To All interesting.
Our 1W 637nm is using 8pcs 170mW(Oclaro) diode, after combine, we got about 1.2W, as I know, many manufactory is using 6pcs to do 1W, factually their power is not match 1W(At least my cohrent power meter test is).
We just want to using the red in safety current and give customers more power.
Best regards!
