Good product and delivery time prompt. Very good product


Growing Light! LED's does no put out alot of heat, like the Ultra Violet florescent bulbs do.

Emily G

Great Product. Impressed with this product. My Bell peppers have done incredibly well under this light. Ordered a second light, have the 2 foot and 4 foot light. Seedlings grew so fast, needed the larger light to allow for them to spread out. The pepper plant leaves are broader than what I've grown under fluorescent T5. Another benefit, my plants are not leggy. Stalks are nice and thick. You can pull the light close to the plants after they sprout which was great at first. Eventually moved the light about 18? above them as they have grown larger and continue to grow. Plants have a nice Bush appearance. Also obtained great results with parsley and am now staring cabbage, tomatoes, basil and believe they will do just as well. This light definitely has given me a jump on the growing season which can be tempermental at times where I live.


high performance, low cost. This lamp has been phenomenal since turning it on from day 1, I noticed immediate growth improvement. I could not be happier with the performance of these lamps and recommend to anyone.


Great light. The light is great. Perfect for the indoor grow tent I have and puts out a nice, bright, even light. I love it.

Wendy D Fisher

Grow lights. Easy to install and appear to be doing their job.


Company very nice. Really nice.


Performing LED at excellent value. Amazing light. Almost no heat output - be sure to plan for that! Also, the switch allows you to turn on only 2 or all 4 bulbs. I thought the fixture was broken at first but it turned out to be an added feature - BONUS ! Support was also very responsive when I messaged them with a question. I will buy again.
