I hate my florescent lights in my MH and I will attempt to replace these when back in the US shortly.
I have made up some spray painted pieces of plywood - same size as the existing florescent lights - and I am going to mount these LED lights
on the boards. 2 LED lights to each board was my idea. The LED's are 2700 Kelvin and I have tested them by connecting them directly to a 12 Volt battery. They work fine and I believe that they are going to make an nice improvement. Time will tell.
I plan to take the complete florescent fitting out, including the ballast, and I will probably install a small 200MA fuse holder and fuse in front of each individual new light fitting.
