FREQUENTLY ASKED QUESTIONS

Q1: Is your product designed for hobbyists or for commercial use?

Our goal is to deliver an affordable and scalable plant lighting solution that’s attainable by both small-scale hobby hydroponics growers and large-scale, commercial-grade medical and licensed installations, indoor or greenhouse.

🔴 Our success is based on filling the need for high quality, affordable solid state horticultural light fixtures that actually do the job.
Our customers are mostly professional growers that don’t use consumer-grade products due to their low efficiency and short life.

Q2: Can I buy your lights on Amazon, Ebay, or other e-commerce websites?

No.  Our products are professional-grade, a step above the quality of the consumer products you find on Amazon and other consumer web sites.  We will be pleased to work with you, including special quotes and extended warranty that is available for large commercial projects.

Q3: How can your light fixtures reach such a high system efficacy? How accurate are your published specifications?

Our Canopus series grow lights use the latest Samsung and Osram LEDs, hand-picked from top-shelf bins.  Unlike Chinese-made “Epistar”, “Epileds” and numerous other LED chip names used by competitors who sell less expensive product, LEDs that we use are the best performing LED chips in the world. 

🔴 These LED chips are the true Lamborghinis of the LED industry.

Samsung and Osram LEDs are expensive.  We also use lots of them, with more than 3000 pieces in certain 800W models.  This is how we reach industry-leading performance and life longevity.  Both are fully documented by NRTL certified independent testing laboratories.  For example, most consumer brands use only about 300 low-cost LEDs in their highest-power, 600W lights.

WE INVEST IN QUALITY, NOT FLASHY INTERNET PRESENCE AND HYPE
Some of the known brands recognizable by multiple cooling fans, advertising “proprietary intensified x-band spectrum” and fancy looking remote control systems, invest in sleek web sites, Youtube marketing videos, and a tsunami of what seem to be mostly over-hyped web reviews.

These companies publish Watts, and push you to buy even more watts, but they never publish the true efficacy of their products.

Other brands not publishing, or reluctant to give third party test reports are, to say the least, suspicious.

Our own tests, performed on precisely calibrated equipment, confirmed that the efficacy of most of the brands known within the hobbyist community, only reach between 1.2 and 1.5µmol/J.

Independent testing labs have confirmed the efficacy of Bluetech’s light engines to be 2.812µmol/s. This means up to 100% more photon output using the same power as competing light fixtures (download certified test report here).

It takes five of our established competitors’ light fixtures, at the same per-fixture wattage as ours, to deliver the same results as just two Bluetech Canopus industrial lights of the same wattage.

In other words, 🔴 one Bluetech Canopus 640W delivers the same PPF, or Photosynthetic Photon Flux energy, in µmol/s, and results as 1100W of grow lights from popularly hyped consumer brands.

Such substantial savings cannot be ignored as they can add significant amounts of money to  grower’s bottom line.

The above statements are sbased on test reports produced from calibrated laboratory testing equipment, and are not intended to bash our competitors.  Our competitors’ lights also produce results, mostly in hobbyists grow tents, but to match the yield results of our product, you would have to buy more of their lights, using up to 100% more power due to their inefficiencies and cooling requirements.

Q4: I tried several imported LED grow lights, but their results were disappointing. Some of them also died quickly, and I was unable to get any help from the supplier. Why should I buy another Chinese brand?

The LED grow light industry has exploded in the last few years.  Along with that, a huge number of off-shore low quality LED manufacturers, have started selling lights that either don’t produce the results they claim or simply don’t last.  In most instances, both. This led to disbelief that LED technology can produced results desired by commercial growers.

Low quality, performance and short life is definitely not the case with all lights made in China. In fact, some of the best LED grow lights (and other electronic products) are made in Chinese factories.

If you’ve had a bad experience in the past, either with a low-quality product or getting support, we guarantee that you will not have this kind of experience with Bluetech.

All of our manufacturing processes are certified to strictly adhere to the ISO9001:2001 international quality management and ISO14001 environmental management standards. Our warranty and post-sale service is one of the best in the industry.

🔴 In addition, our Toronto-based, fast responding North American customer service engineering support staff is available 6 days a week through SMS/Text, email or fax. See contact page for details.

Q5: What type of lenses do you use?

Although our competitors claim “best penetration down to bottom branches” by using mostly narrow-beam (90-degree or 60-degree or “mixed”) lenses, we decided to stay away from lenses because every lens, no matter how well designed, absorbs anywhere from 10% to 15% of the valuable photons emitted by the LED.

Research has confirmed that for every 10% drop in light output, yield will also be reduced by 10%.  

🔴 Lens reliability can be an issue
Lenses are usually made from plastic that will deteriorate over time, leading to even greater light losses at the lens.   If we were to use plastic in the optical path of our products we would be unable to offer our unique 6-year, no questions asked, bumper-to-bumper performance warranty.

Q6: How can you get proper “punch” without lenses?

Instead of plastic lenses, our Canopus series light fixtures can use optional 98% pure silver coated aluminum reflectors made by the German company Alanod.   Despite the material used in Alanod reflectors being up to 20 times more expensive than the plastic used in lenses, we chose these reflectors for their legendary reliability.   For the same reason, German Alanod has been a favorite reflector material in horticultural lighting since the beginning.

The light loss from the LEDs to the plants has been verified to be negligible – less than 0.5% light loss.   In addition, unlike lenses, reflector-based optics deliver more diffuse light at lower angles, leading to better canopy penetration with beams coming in under low angles.

Bluetech products deliver optimum optical performance in any type of indoor or outdoor growing application.

Q7: How difficult is to keep reflectors clean?
Shiny aluminum reflectors have been used by growers since the very beginning. Cleaning reflectors is a common skill and is very easy. All you have to do is wipe them down with a dry microfiber cloth when you notice they are dusty. This will keep your Bluetech lights always running at maximum performance.
Q8: Are your cooled by fans as I see on many other brands?

All of our products, including the Canopus series, are engineered with high performance, anodized aluminum heat sinks with large surface areas. Our heat sinks are designed so that they dissipate enough heat to cool the light fixture without needing fans, in all kinds of environments that can be found in indoor growing facilities.

🔴 Fan reliability can be an issue
Besides the constant droning of a fan as background noise, fans, just like other moving parts, are prone to failures and shorter life due to dust and moisture penetration

Q9: What kind of energy savings I can expect when switching from Sodium to Bluetech light fixtures?

Using the dimming schedule specified by this article will result in energy savings of up to 80% without compromising your yield. This method will guarantee you fastest return on your investment.

Q10: How long do I have to keep the original packaging for?

Other manufacturers ask you to keep the packaging for up to 3 years, or the length of their warranty, so that you can use it when you need to ship their product back for a warranty claim.

🔴 Each Bluetech light fixture is visually inspected and tested at full power for 72 hours prior to shipping.

As a result, the chance of a short-term or long-term failure is extremely small. Our records show that the 6-year failure rate of our LED products is only 4 fixtures per thousand produced, so you can be assured a warranty return is highly unlikely.   Feel free to dispose of or recycle all packaging materials right after you unbox your lights.

Q11: Other manufacturers, including the biggest commercial brands, provide a 3 year warranty. With your competitive prices, how can you afford to offer 5 warranty?

We offer a five year warranty due to our nine-year track record of very few failures, with a rate of only 4 failures out of every 1000 units produced (a failure rate of 0.4%). This gives us confidence in the functional and performative longevity of every fixture we manufacture, and allows us to offer a longer than standard warranty.

While all other manufacturers maximize their profits by using materials and components that are only rated to the absolute minimum, we are the only company in the world that we know of, that has lifetime customer satisfaction as our top priority.

🔴 To us, the customer’s experience is more important than maximizing our bottom line by using inexpensive components.

All internal power connections and wiring inside Canopus light fixtures is rated for 15A, to ensure any chances of heat-related failures are eliminated.

Furthermore, we use a meticulous four-step method for joining power wires, where the end of the wire is stripped to a specific length, hand-twisted, soldered, and crimped. To our knowledge, no other manufacturer manufactures their power wiring harnesses in such a diligent way. Thanks to our process, and the use of 12AWG wire for grounding the chassis, reliability and safety are maximized where they matter most: in your production facility.

As a final touch to ensure the reliability of our grow lights, the we deeply under-drive the LED chips we use, powering them to only 40% of the maximum rating specified by the chip manufacturer. 

By forcing less power through each individual LED, temperatures are kept substantially cooler than the maximums imposed by the manufacturer.  Cooler temperatures then lead to less wear and tear on the chips, and a longer lifespan for the light fixture.

Q12: How can I get technical support and advice? How can I claim warranty, if needed?

You can contact our factory directly or use our Toronto-based, fast responding North American customer service engineering support staff that is available 6 days a week through SMS/Text, email or fax.  See contact page for details.

 

Q13: Some manufacturers use 3W, 5W, or even 10W LEDs. They say that the more watts passing through each LED, the better. What is the watt rating of your LED chips?

Differences in efficacy between LEDs with different power requirements are not a myth, as some manufacturers would have you believe. However, with many products on the market, it can be hard to understand the difference between the multitude of available LED fixtures.

This is the true difference between 1W, 3W, 5W, 10W, and COB LEDS

Many LED grow lights contain 1-watt (1W), 3-watt (3W), or even 5-watt (5W) LEDs and claim to be the most efficient. However, no manufacturer can claim they use the most efficient LEDs. A 1W LED is more efficient than a 3W LED at producing light, and a 3W LED is more efficient than a 5W LED, in terms of photons produced per joule (or Watt) of energy used. However, a 0.5W LED is even more efficient than a 1W LED, and the most efficient LEDs produced to date use 30 picowatts (0.00000000003W), so in this sense 1W, 3W, and 5W certainly cannot be the “most efficient”.
Bluetech grow lights use the latest LEDs from Samsung and Osram, hand-picked from top-shelf bins. These LEDs are the highest-performance, commercially-available LED chips in the world. They are the true Lamborghinis of the LED industry.

These Lambo-quality leds are expensive. In order to maximize efficacy and extend longevity, we under drive these LEDs by using lots of them, with up to 3000 pieces in certain models. (Our Kind-est competitor only uses 320 LEDs in their highest power, 600W, light). This is how we achieve the best-in-class performance documented by NRTL-certified independent testing laboratories.

🔴 A word about COB
Chip-On-Board (COB) or “integrated” LEDs are created by placing many low-wattage (typically 0.5W or 1W) LEDs side-by-side on a small circuit board. This allows companies to claim very high wattage LEDs, however in reality high-wattage COB LEDs are just numerous smaller LEDs together on one small area board. It is not yet feasible to use higher-wattage COB LEDs, as they generate too much spot-focused heat for current cooling technologies to effectively remove. As a result, fixtures built with these LEDs would not last long enough to meet the requirements of the professional grower.

Q14: Do you make growlights which take 347V power as input for Canadian growers?
Yes. Bluetech 347V lights use high-voltage drivers with an input range of 180VAC-528VAC, and are thus also suitable for 347V Canadian and 480VAC US systems.
Q15: How can your LEDs last more than 100000 hours? Most manufacturers claim their fixtures last only 30000-50000 hours.
Because LEDs do not have filaments or bulbs filled with gas, which can break down after years of heating up and cooling down, they have a significantly longer lifespan than traditional lighting technologies. Even cheap LEDs are rated for a lifespan of over 50,000 hours, while the top quality LEDs used by Bluetech from Samsung and Osram are rated for over 90,000 hours when installed in adequately cooled systems.

At an average 12 hours of daily operation, Bluetech products are rated for a 25 year lifespan, where an LED fixture is considered to have reached the end of its life when its lumen output has decreased by 30% from its initial level. LEDs do not burn out like traditional lamps, they just get dimmer over time.

Q16: I like the build quality, test results, and reviews of your products, but I only see full spectrum grow lights listed on your webpage. I’m still convinced that a specific red/blue mix is the best for my needs. Can you help me with this?

Yes.  We can custom-configure any of our horticultural products to any spectrum the customer needs. Including pure blue/red or adding green, orange, far red, infrared, UV, etc. We also offer high performance, adjustable and tunable spectrum systems as well.

However, note that custom configurations require a minimum order quantity, and lead times and prices will be quoted separately from normal products.

Q17: What type of plugs do your growlights come with? There seem to be so many options!

In North America, the Canopus flagship series comes with a non-removable 3m (10ft) long cord terminated by NEMA 5-15P grounded plug for standard 120V wall outlets. For NEMA 6-15 240V outlets we recommend to use on of readily available adapters.

We can also supply any of the plugs shown in Fig. 1 below. However, note that customer-specified plugs require a minimum order quantity, and lead times and prices will be quotes separately from normal products.

Q18: How many watts worth of high pressure sodium (HPS) lamps can the Canopus replace?
The Bluetech Canobus SE can replace one 1000W single-ended HPS grow light. To replace higher-end 1000W double-ended high performance fixtures, we recommend the installation of Canopus DE.
Q19: How many Canopus SE or DE lights can I connect to one 120V outlet?
Up to three Canopus SE grow lights and two Canopus DE lights can be connected to the same outlet protected by a 15A fuse, assuming that no other appliances are connected to the same circuit. Downolad Installation Instructions for details.
Q20: What kind of dimming schedule should I use to maximize my energy savings, without compromising my yield?

The impact of dimming schedules on yields is discussed in this article.

Q21: Are your grow lights more suitable for indoor growing or for greenhouses?
We offer two standard spectrums across our product range, one for indoor growing (FCSI) and one for greenhouses (FCSG).
Q22: What are your standard spectrums?

We followed a results-oriented approach to designing our two standard spectrums.

🔴 Cannabis full-cycle spectrum for indoor – FCCI

Green light is a vital part of Bluetech’s full-cycle spectrum, indoor (FCSI), which is optimized for precipitated growth and thorough plant development in indoor production environments.Straightforward and easily understandable, the fullness of the FCSI spectrum is tailored for growing plants from propagation to senescence (germination, clones/cuttings, mothers, vegetative, and flowering applications) in indoor environments. 

🔴 Cannabis extra-bloom for indoor – EBCI

EBCI spectrum with enhanced 660nm wavelengths is configured to maximize yield in the purpose-specific flowering rooms. Elevated concentrations of CO2 are recommended to maximize yield under this spectrum.  Contact factory for details.


🔴 Bluetech full-cycle spectrum for greenhouse – FCSG

Bluetech’s full cycle spectrum, greenhouse (FCSG) adds more energy in the 400-500nm (royal blue) range, which is used to eliminate tall plant stretch that can be induced by the sun’s far red radiation.  IP67 certified green house model will be available 1Q 2019.

Pleasing environment, increased work productivity and small-task accuracy

With a minimum CRI rating of 90, Bluetech’s spectrums offer a visually comfortable work and research environment with vivid colors and greater contrast that enhances small-task accuracy, important in surveying the health of your crop.

Q23: Do your lights replicate sunlight, high pressure sodium (HPS), or metal halide lamp spectrums?
No. Our intent is not to mimic the spectrums of legacy systems or sunlight, or to market a “proprietary magic spectrum” in our light fixtures. We focus on and market the real, result-oriented, and meaningful specifications of our grow lights.
Q24: Why don’t you use fans? Don’t they provide better cooling?

🔴 FAN RELIABILITY CAN BE AN ISSUE
The commercial greenhouse environment presents numerous hazards to moving components, such as moisture and dirt. In this environment fans and water-cooling systems have proven themselves to be unreliable.

This is the main reason why our design engineers eliminated moving parts from our luminaires. Every Bluetech light fixture is passively cooled and protected against humidity, and when dimmed through our suggested energy-saving light recipes (download here) it offers a real 100,000+ hour lifespan (L70) with only a minimal maintenance.  All is covered by our exceptional bumper-to-bumper, no questions asked six-year warranty

Q25: I don’t see an option for remote controls offered on your web site. Why not?

The majority of our customers have stated that they do not find remote control systems for their grow lights useful or necessary, so we chose not to offer it and pass the savings on to the customer. Furthermore, there are currently no grow light remote control systems on the market that are reliable enough for us to cover with our 5 year bumper-to-bumper warranty.

Q26: How close to the canopy can I install your lights?

Bluetech grow lights must be installed a minimum of 18 inches away from the canopy, 640W models, and 24 inches with 800W models.

Q27: What happens if one LED fails? Will a whole string of LEDs burn out, as I’ve seen on other LED fixtures?

No. Although single LED chips can fail in any grow light, our lights are designed such that if one LED fails it will not affect too many any others or the function or performance of the overall system. The light output will remain without any changes.

Q28: Is failure of individual LEDs covered by your warranty?

No, as our warranty covers the performance of the entire grow light.  If one or few LEDs fail of the thousands on each fixture, they will not impact the performance of the fixture in a meaningful way.

Q29: Can you ship your lights in neutral packaging?

Yes, our factory and our distributors typically ship Bluetech products in discreet neutral packaging.

Q30: Do I have to adjust the dimming level on Bluetech lights, or can I use them for the entire grow cycle without touching them?
You can use Bluetech grow lights for the entire cycle without dimming, however dimming offers the potential of significant energy savings without compromising yield. We discuss our recommended dimming schedule here.
Q31: In a commercial setting, can I dim your lights remotely?

Yes. Bluetech grow lights can be controlled using our simple and reliable plug-and-play wired connection, which supports up to 40 light fixtures in a group and control from up to 300’ away. Large facility customized control systems that can control hundreds of lights from one screen, will be available in 1Q19.

Q32: Some manufacturers offer a convenient wireless system control. Do you offer the same?
Wireless systems are more convenient to install but result in substantially higher costs to the customer. Commercial wireless control systems require transmitters, routers, hubs, a receiver for each light fixture, and usually external contractors to setup the entire system. Our robust wired interface is simple enough to be installed without needing technical expertise, and achieves the same goal as a wireless control system.
If absolutely necessary, we can specify a third-party wireless control system to use in conjunction with our products, however note that this requires a minimum order quantity and that prices and lead times will be quoted separately from normal products.
Q33: Do I need IP65 rating for grow lights use in indoor facility?

No. Current Electrical Code in most regions require dry location or damp-location rating (UL1598) for light fixtures used within indoor facilities.

To enhance the value offering to our customers, Bluetech grow light fixtures will have available (in 1Q19) IP67 protection option that will be certified to withstand water submersing to 10 feet, for 30 minutes.
