I read some post in the forum and i see R5 driven at 1A, 1,4A and also 2.1A... Now, assuming a standard host (502 or 504 for example) and heatsink on this host, which is the "right" current for a R5?
A 3x7135 circuit would be enough? (Like this, for example)
This is a good question. Much like the xm-l, there's a lot of speculation on gains after 1.4a for the xp-g. I'll try and get around to testing it, much like I did the xm-l and mc-e. The sst-50 is next though.
Is your post with the test of the emitters that "create" my question. I see that emitter have a sort of ideal current. If you use lower current they lost a lot of lumen, if you use more current you gain only few lumen...
