Finnex 48" LED @ 39 Watts. Lights are 7000K and perfect for growing. I own 2 other finnex lights that grow plants awesome. This light is basically new and has been sitting around for the last 6 months collecting dust. I decided to go smaller and dont need it. http://www.amazon.com/Finnex-Ray2-Aquarium-Daylight-48-Inch/dp/B008K3DO9I check out the light for reviews and such. Great item, havent had a problem with my other 2 lights that have been going strong for over a year. Need to get $140. New is over $180.
