UC3A Internals and Emitter Swap
This swap was probably one of the easiest/quickest I’ve ever done. One reason for this is that there’s no thermal paste involved.
First I tried some FFL351a in 3700K. The beam hotspot is so very narrow on a domeless emitter paired with these optics. I just didn’t like it that much.
Second, and final, a pair of Nichia 519a’s in 4500K, dome on. Love it. It matches pretty well with the white side light.
The internals are in one piece and pop out easily once all the screws are undone. There’s a silver post with some notches for a flathead screwdriver to screw tight that securely holds the internal chassis in place.
