I used DDH-M0B, XiangNan 6v5a boost driver and a very special emitter to build a light. It’s the 2nd DIY light I built for myself.
The emitter is called “FL7018R”, which is a 95 CRI 6v7070 emitter with relatively high efficiency and very rosy tint (the best Ive ever seen).
The emitters are from dark_dreamer. He did some simple tests of its efficiency:
1a 724lm
5a 3090lm
9a 4870lm
15a 6650lm
Here are some infos about the emitter.
Due to the limit for new users I can only post one image here. If anyone gets interested, I can upload some beam shots and CRI comparisons
