    Excellent. Have a Ficus which typically looses its leave during the winter months and using this has essentially allowed it to thrive throughout the Colorado winter.

    This light has kept my flowerpots alive all winter in a dark basement. I have the light on a timer for 15 hours a day. I can't wait to put my seed geraniums back outside. They will look amazing and be flowering in no time!

** 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.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.
7.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
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
