I purchased Sylvanian 6ft, 5ft, and 4 ft LED batten fittings, These fitting were totally new to me and had I had a good look at them before hand I would not have bought them. The terminal on the top of the fitting has only room for one cable and are push in terminations which doesn't go down very well with me, Loop in and out wiring system is impossible. The fitting are not vert practical as far as installation is concerned. If you are expecting to mount on beezer boxes to replace older fluorescent fitting, these are the wrong fittings. Out of 5 fittings one failed after two days. The light output is good. I had a phone call from the company to see if my order was all okay. Unfortunately I have not unpacked my order at that stage. I would not buy these fitting again. Sadly Disappointed.
