I've seen several forum members with displays that need lighting repairs or upgrades and seen IUSteve's thread about his problems getting parts to work together: ballast, lights, LED's, etc. I educated myself a little on LED's and drivers and found some components that looked like slam dunks so here's a DIY. Starting with single wide that already has a halogen light the process is easy because 120v is already run to the top of the display and a hole is already cut in the ceiling. Here it is with one 20W halogen: Kinda yellowish halogen light temperature: Remove the top of the display that has the lighting components. This display has the remnants of a fluorescent lamp as well as a puck with a halogen. No mind though, all of that is getting stripped but I'm leaving the black box with the switch so that I can distribute power in the top and still be able to switch on and off: I flipped it over and drilled out all the rivets that held all in place except for the black box which I'm leaving mounted: Then you have this left: And a hole in the top of the display: The new lamps are a perfect fit out of the box, have their own bezels and hold themselves in with spring feet: Insert the new lamp into the display ceiling: Splice the driver wiring into the 120V in the top of the display using wire nuts, a 120v male plug, whatever and refit. That's it. I plugged the LED driver leads into one of the switched 120V outs on the black box. I really only use that box as a switched power source. So here's the display with the new LED lighting from the top: And plugging in the LED rope lights from a previous display mod: You get this complete solution: These LED's can also be used in a non-lighted display since they are complete with driver and mounting / finishing hardware. You would have to bore a hole in the top of the display to mount the light and run 120v though the uprights but that is pretty easy. For me the education curve on lighting, ballast, transformers and drivers along with finding the right driver and LED combination was the harder part. The LED's that I sourced will work with a variable AC voltage of 84-240v so they can be used in US (120V) as well as UK (220V) applications. It's really that easy, in fact I did this upgrade and shot the pics in about 20 minutes while having a phone con with Infinite Hero. PM me if you need additional info on these.
