A video I made last night of my EATPM. LED's can be done in different ways. I tend to try to keep the original look of incandescent bulbs by using warm white LED's on the GI and then matching the insert color to the LED. A little color here and there for personal taste.
I also shot video of my IJ and TZ but I haven't uploaded them yet. With my TZ I went more cool white GI just to kinda change its look a little. My IJ is straight warm white, and it looks really close to incandescent bulbs.
The biggest reason is the energy efficiency this leads to less stress on the boards, wires, plugs etc. my TZ would randomly reset no matter what I tried. Going all LED actually helped.
