Hi guys I have just installed a new system in Firgrove, the customer wanted state of the art electrics and T5 tubes. Well I must add, I fitted 4 x 80w daylight tubes and 6x T8 plant tubes. I tell you , those 4 daylights are bright. The length of the tubes are 1.5mtrs. I will post some pics soon. The T5 tubes are operated from Osram electronic ballasts and each ballast runs 2 tubes. I must add that those T5 tubes get hot so watch out for DIY reflectors.
