Rated 3.9 out of 5 by 11 reviewers.
Rated 5.0 out of 5.0 by Good buy I have owned this light for about 2 weeks and it does great. Easy to use. Removing the lenses was a little tricky, but not very complicated. All in all a very good grow light. The extra outlet is great. I plugged in my seed starting heat mat and it works great. I will be purchasing another soon for my indoor garden. March 7, 2015
Rated 2.0 out of 5.0 by Had to use duct tape The fixture insides are drooping on one side and I had to use duct tape to hold it together. I would have sent it back but my seeds have sprouted and I need it now! March 11, 2015
Rated 5.0 out of 5.0 by Small greenhouse We have a small indoor greenhouse made up of shelving and the grow lights. We have purchased 6 of these lights and are very happy with the results. We started seeds in March and are now ready to plant in the garden and yard. April 29, 2015
Rated 4.0 out of 5.0 by Good Value Easy to install and use, but removing the diffuser in order to remove the cardboard from the bulbs was difficult, and I cracked it. Product could definitely use better illustration/photo here or better yet, another type of attachment. Great to find the chains for hanging included in package! February 15, 2013
Rated 5.0 out of 5.0 by Excellent product for doing my starts for my garden. Excellent product to get your garden started. Easy to hang and easy to adjust as youor plants grow. April 1, 2014
Rated 2.0 out of 5.0 by Nope, only kept it because I need it. The inner unit (light bulbs, etc) came loose on one side and I needed to tape it up so it wouldn't fall apart. March 12, 2015
Rated 5.0 out of 5.0 by Excellent features though a bit tricky to install Excellent value and well made. The ability to piggy back is VERY helpful in the hothouse. The light covers are tricky to remove and install, otherwise this is an excellent product. My plants are thriving this winter! January 24, 2014
Rated 5.0 out of 5.0 by Satisfied The unit is good looking and is doing its job providing very good lighting for my plants. I removed the cover over the tubes since that gave me more light. I then used the cover as a baffle on the each side of the unit to prevent light from the tubes glaring into the rest of the room. March 19, 2013
