  • Actual scientific conclusion about the TT-GL20's performance.

    Hey everyone, 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.

    I should clarify something right away: I have no idea what I'm doing. I did the absolute minimum in regards to researching this before I purchased it. I do not have a green thumb. In fact, my thumb is so far from green that it might as well be petrified wood. I am one of those
    I should clarify something right away: I have no idea what I'm doing. I did the absolute minimum in regards to researching this before I purchased it. I do not have a green thumb. In fact, my thumb is so far from green that it might as well be petrified wood. I am one of those people who should not be allowed to have houseplants, not because I can't keep a living thing alive but because it helps if that living thing can make noise at me when it wants food. That being said, I bought this with the clamp light because my aloe plant has been looking a wee bit limp and sad. I put everything together and turned it on my plant for a few hours. One of the very first things I noticed is that the leaves seemed to have fattened up. They were looking pretty thin and skinny before, so I'm taking it as a plus sign. I haven't noticed anything else really. I just purchased more plants, because I might as well just make it a party or something. They're still healthy and don't seem to respond positively or negatively to the light. Maybe a 5 star review isn't necessarily warranted because I have no idea if it is actually helping. However, I have noticed some improvement, everything arrived packaged and as described and I have no reason to take off stars for this review.

    l've had these 'Hydroponic LED Grow Lights', from TaoTronics, for a little more than a month; I purchased two, for considerably less, and intended multiple purposes: first I was curious to see if the lights would encourage growth of transplants from a fig tree that hasn't produced matured fruit. I grew the tree from a cutting, and have maintained it as a shrub, and it produces fruit but cold weather prevents maturation - my fault for not providing proper Winter care - and I decided to do some experimenting. During Fall I transported rooted canes, with dormant buds, to containers and have had the lights on them for less than a month; buds are blossoming. While waiting for that to occur I also planted herbs, within the same containers, and they've been doing very well also. I've become curious about hydroponics, too, and will use the lights to propagate a variety of vegetables for Spring transplanting into the garden and containers as well. There's room in my utility room to accomplish all this but the arrangement I've made is a bit haphazard at the moment, as the photos show, but successes will encourage better planning.
  • Work great when used at their intended distance from the plant - about 1/2 meter (2 feet or so)

    Note the picture for the device and how close they have to be to the plant. I bought four along with Woods 0151 18/2 SPT-2 Clamp Lamp Lights to give some extra light for house plants that are relegated to the basement in the winter. These do not put out enough light to really be effective for large house plants, unless the lights are directly over and close to the plant. But used in conjunction with a large parabolic reflector equipped with a 400w halide grow lamp, they help. Edit - I have increased the rating of the product due to the fact that it might be my error in not noticing in the pictures how close the lamps are to the plants. Also, the manufacturer contacted my about my review and was very helpful. I like it when a manufacturer backs up their product. They stated that they are good when used 0.3-0.5 meters from the plant. I can definitely see them working well at that distance.

** Amazon Customer Questions & Answers **
The questions and answers below were created by Amazon customers, who are not affiliated or in any way officially connected with Taotronics. Please follow their advice at your own discretion.
1.does this fit a Standard light bulb socket??? Customers are chatting about this View conversation
A: Yes
2.how much distance should i leave between the light and the plant? (I am growing herbs and leafing greens) Customers are chatting about this View conversation
A: The closer the better. I usually start at three inches and keep the light about that far from the growing tips. The further you go from the growing tips the less light falls on them (Inverse Square Law) For my big trees the light sits right on the top leaves. Doesn't burn the leaves and the light that penetrates the top leaves is that much closer to the lower leaves. The item's "suggested height" is meaningless. New growth is tender and sensitive. Established leaves are more hardy. If you put the light too far away the plant will use whatever energy it can get fro the light to grow towards the light. you'll get pale, leggy, stringy plants. The closer the light can be to the growing tip of the plant, the more energy the pant has for photo-synthesis. And it will spend all that energy making rich, dark green, succulent leaves. The old incandescent-type lights made light by making a lot of heat. An d heat dries out the soil and burns too close leaves. The point about thee led lights is there is not supposed to be much heat at the light genarating end. Though there can be heat behind it in the diode part. Just try to get the light as close as possible to the plants growing shoots. Test the light source heat with your hand. The closer the better. --The other thing is differential growing. If some plants grow low (some herbs) and other plants grow high you will have a problem. You want all the growing ends to be about the same distance from the light source.
3.will this work for germinating vegtable seeds Customers are chatting about this View conversation
A: Assuming as I think any sensible person would, that this person meant "seed starting", the answer is no. More evenly distributed light is better for seed starting, like fluorescent tubes. Particularly when they're just starting out, light spectrum is basically irrelevant, any "white" light will be satisfactory if it's bright enough, and light intensity is not "too" important, since fluorescent lights can also be placed very close to the plants (and seedlings are of course short). And in any event, calling this light "full spectrum" is ridiculous as a quick glance at the stated specs makes quite clear.
4.what is the plant coverage for this bulb? Customers are chatting about this View conversation
A: I think its about 2' but its only good for short plants , if your plants are going to be over 16-18" the lower part of the plant wont get enough light
5.Will it be good for one mature tomato? Thanks! Customers are chatting about this View conversation
A: I would say no - a mature tomato needs more sunlight than this unit will provide to reach all the leaves. a bank of these lights would be good for indoor tomato plants if legal where you live
6.I just got this bulb and it is noticeably flickering. Is that normal or do I have a bad bulb? Customers are chatting about this View conversation
A: Plug it in somewhere else as a test (check to see if it is your power at fault). If it flickers still then it is bad and you should return it
7.Does it emit any Ultra Violet rays that are harmful to humans (skin cancer, eye damage)? Customers are chatting about this View conversation
A: This bulb does not emit any ultraviolet light. The wavelengths of the LEDs is in the specs as: 460nm, 620-630nm, and 660nm. These are all within the range of visible light (400-700nm) http://en.wikipedia.org/wiki/Light. Ultraviolet is from 400nm-10nm http://en.wikipedia.org/wiki/Ultraviolet. There's no need for any eye or skin protection.
8.hoe does this compare to lumen out put of a cfl ligh? Customers are chatting about this View conversation
A: It's about as good as a standard mid watt CFL. But the difference is, this LED is like a flashlight. Bright over a tiny area, almost nothing if you go outside the circle. A CFL will get you light over a huge area. Also I found the lumens were not that high. These are very dim LEDs compared to what is used in normal LED grow panels today (5W). Get this as an emergency light to keep a plant thinking it is a certain season, but it's not good for additional lighting or main lighting for growth or fruiting.
9.How often do you run the light (for how long)? How has using the light reflected on your electric bill? Customers are chatting about this View conversation
A: if its 12w and your electric company is charging you 12cents per KW., if you have it on for 24hrs/day for 30 days, then you will be paying exactly $1.0368
10.For larger plants, like tomatoes, would adding reflective material to the grow area help with the base of the plant? Customers are chatting about this View conversation
A: Yes
