Seedlings to harvest
The TaoTronics grow light is suitable for all stages of plant growth, flowering and fruiting. Its relative compact size making it excellent choices for cloning and seedling lights since they can be placed in tight spaces without worrying about heat increased.
Less heat, more growth
Keeping heat off plants is essential. By using aircraft grade aluminum and a unique heat sink design to maximize heat dissipation area, the LED maintains a cooler temperature even after 24 hours of continuous use.
LED lights have average lifespan of 50,000 hours. It uses far less energy and emits much less heat than fluorescent lamps. The best part is it works on standard light sockets so you do not have to purchase any special housing for the bulb.

Nutrient delivery is computer controlled and precisely monitored. Over the last 18 months I ran experiments in DWC hydroponics STERILE, DWC "Bennie", Aeroponics, Ebb and flow, ebb and drain, Kratky method, and full aquaponic systems.
The TaoTronics LED Grow Lights are legitimately the best build quality and subsequently have the best heatsink (thermal efficiency) out of 46-50 "LED light bulbs" I tested over the last year. After running these 24/7 you can easily touch ANYWHERE on the entire heatsink without feeling much heat. Amazing!
Out of all of the LED multispectrum panels and LED light bulbs that I tested in the 60watt (or below) category, these 36w bulbs delivered the *****BEST**** PPFD (Photosynthetic Photon Flux Density) and overall visible growth results in all plants.
With the Quantum par meter, these rockin rollers amazingly put out 600-700μm (micromoles) at 3ft. That's absolutely impressive. Bringing the quantum meter closer (and still very comfortable for plants) to around 1-1.5ft the Taotronics LED Grow light easily reaches 1300-1800μm! I currently have THREE 1200watt LED multispectrum grow lights bought off Amazon that have HUNDREDS of positive reviews, that these Taotronics are literally stomping all over in output AND thermal efficiency!
There are cons though.The spectrum falloff is SEVERE, meaning that the effective diameter of coverage is small. They have a spotlight effect, the center is always receiving a significant amount more light than the edges. While increasing the distance (obviously) increases the diameter of coverage... I would say the ideal effective range for these is from 4ft all the way up and cozy to 3 inches.
To provide a comparative perspective, marijuana seedlings thrive when you start seedlings with a minimum of 150µmol, preferably 300µmol+, teen (2 weeks into VEG or futher) marijuana from healthy strains are known to prefer a minimum of 500µmol+ , and recent studies by NASA and The Department of Agriculture show that marijuana thrives best at around 4000µmol, something that most (singular LED lights) LED's are not capable of for long periods of time (4/21/2017) without peltier/watercooled assistance. Most of the good LED lights kick out around 1200-2300µmol and the ones that do it continuously RELIABLY and run cool to the touch, will cost anywhere from $900-4000.
You can use the following calculation to determine the hourly PAR. Substitute your actual instantaneous PAR measurement for the '55µmol’' below:
Hourly PAR= (55µmol / m^2s) ( 60s / 1min) (60min / 1hr) (1 mol / 1 x 10^6µmol) = 0.36 mol / m^hour
In case anyone isn't tracking along, here are some definitions:
Humans use Lumens. Don't measure a lights effectiveness by it's luminosity. If you do, you're just an idiot. The FEIT 300watt LED $40 bulb is extremely bright and can light up a .25 acre backyard, it's marketed as "stadium lighting replacements" however it puts off a miserable 100-300µmol within 2" of the bulb and leans too heavy on the blue spectrum side. It doesn't work well at all at replacing a grow light.
Plants use PAR, PAR stands for photo-synthetically active radiation (PAR). PAR is NOT a measurement or “metric” like feet, inches or kilos. Rather, it defines the type of light needed to support photosynthesis.
The three factors anyone (even little ol granny growing Magnolias indoors) should care about when growing under artificial lighting is:
PPF - Photosynthetic Photon Flux, PPF measures the total amount of PAR that is produced by a lighting system each second.
PPFD - Photosynthetic Photon Flux Density (PPFD), measures the amount of PAR that actually arrives at the plant, or as a scientist might say: “the number of photosynthetically active photons that fall on a given surface each second”.
Photon Efficiency....Photon Efficiency refers to how efficient a horticulture lighting system is at converting electrical energy into photons of PAR. Many horticulture lighting manufacturers use total electrical watts or watts per square foot as a metric to describe light intensity. However, these metrics really don’t tell you anything since watts are a measurement describing electrical input, not light output.
Micromoles (looks like this µmol ) – Intensity of a light is measured over a fixed area to understand the ability of a light to cover an area with that intensity (coverage). Micromoles of photons per square meter per second (µmol/m2/s) measures the intensity by taking measurements in a consistent 4 x 4 grid, measures the coverage of that intensity–commonly known as PPFD per 4 x 4 grid. Rather than measuring light intensity by lumens per watt with a lux meter, growers should use a quantum PAR meter to measure the micromoles of photons per square meter per second (µmol/m2/s) at the canopy level. To best calculate PAR light intensity coverage using PAR mapping 4 x 4 grids, be sure and measure at various heights. Spot readings (PPF) metrics are misleading. G rowers use PPFD per square meter to accurately measure intensity and coverage of that intensity.
If you want to be mindblown......, the $26 Taotronics 36w LED grow light BULB puts out a multispectrum 1500µmol at 1.2ft You would need a couple per plant for large fruits, vegetables or marijuana, but you cannot beat the cost factor and....after running the lights for a week, you can easily fully grab the bulb/heatsink, unscrew it, and it won't even be slightly warm. Also the Roleadro 45w $26-29 puts out a consistent 250µmol for those looking to grow microgreens or tissue culture or seedlings.
If you're like "whoa dood, I'm just trying to grow baby tomatoes for grams and you're going Bill Nye on me", I'm simply saying: I have ordered 6 more Taotronics LED Grow lights to replace a "1200watt LED" which was increasing the ambient room temperature by 12 degrees! The cost savings was nearly $350. These lights are amazing.
If you were to grow larger vegetables or plants, or trees, or even marijuana, you should use 4 of these per (respectable) plant.
About a month later I rearranged the plants and bought two more Tao lamps for better coverage. Well the TaoTronics lights worked better than I could have imagined. The TaoTronics LED lamps run cool and didn't have to water the plants much either. Cheap to run too.
It's now getting close to April and the plants are still healthy and growing. When I get them outside, I'll have the first colorful plants growing on the block..... But first I have to wait for some warm weather and the 3 foot of snow to melt.The worst February winter on record. Yeah it's Buffalo, but the Tao Lights worked for me and gave me summer in my basement.. I waited to write this review to make sure they worked. They did!!!
I have preformed a bunch of searching for the best lighting system to light my next hydroponics build. I tried searching a fair amount for the PAR values that the TT-GL20 actually puts out. PAR measures the amount of plant usable light in the 400-700nm range. Most small greens like lettuce max growth at a total of 34 mol/day. PAR is the honest, non bias way of telling you how much USABLE plant light the plants are receiving.
I bought one TT-GL20 unit to test the PAR output at varying heights (and therefor footprints). One of the images attached is the table from my findings. All distance measurements are in cm. NOTE: All measurements were taken in darkness, so if you have some light in near your grow area, the values from this study would be the minimum values you could see.
Based on my results, I recommend that these lights before best at height BELOW 50cm. With the optimal height to footprint ratio being right around a 40cm height. Once you lower the light fixture below 40cm you are significantly lowering your grow-able footprint.
Additional information: Actual energy draw from this unit was only 9.2 Watts. (Perfectly normal to be under rated 12 Watt draw).
In conclusion, I will be purchasing several of these units (2x5), at a installed height of 30-40cm to cover an approximate 40x150cm grow area to maximize plant growth. Each light fixture will overlap the edge of their footprints by a few cm. For my rectangular system, I believe that using several of these units will best maximize the light used and provide the most stable gradient of usable light.
I hope this helps, if you have any questions please comment below and I will definitely try to get back to them.
