Got my BOG 3W in today - good news and bad news.

Well first the bad news. Testing it with the ceiling bounce test using the ol' eyeball meter, I don't see a BIT of difference in output compared to the 1W. They must be very close in current. There may more difference than I can see now since its daytime, but I closed the blinds and the curtains and still didnt' see a difference. Arghhh. Hopefully when I transplant the Seoul P4 in both of them , the difference will be more pronounced.

The good news is the 3W seems to have no problems running on 2 batterystation 3.7V 900mah protect RCR123s.'

I also have 2 AW 17670s on the way, and I hope they run both modules' in full spec.

what kind of runtime do you get on that 1w with taht tailcap if I might ask?

Which tailcap?
