I bought a LED grow light from a professional LED grow lighting manufacturer named sunprou，LED grow light indeed dramatically promote the growth of vegetable，I have been interested in green vegetables and decided to buy one although the LED grow light is expensive， I found the fashion LED grow light named rainbow from the company，it seems that it would be perfectly suitable for my greenhouse， the saler from the company patiently told me how to install it，but now I got the accessories and grow lighting body, I have no idea about know how to install and the saler have not replied me timely.Who can give me some idea，thank you very much！

Wish I could help you but I am not familiar with that brand, and I have never heard of a LED fixture that needs to be assembled by the consumer. If it is a Chinese brand, I highly recommend you stick with the brands manufactured in the US like California Lightworks, etc.. They seem to be the most popular on this site. But if you post some pics, maybe someone can help.
