Gets vert hot in about 3 minutes. Better than I thought.
Uses 21700 of course.
SFT40s are pointless for this light
1 or 2 21700s?
One of the unique appeals about the OwlEyes is that in its default configuration with the two Osram Emitters, it could run Turbo continuously with no heat problems, and hold a near constant output for over an hour. SBT90s are so power hungry and hot, that they kind of take away from that attraction. I would have thought maybe the SFT40s would provide the same intensity and heat generation as the Osrams, but maybe a little more output.
3 minutes with 2 SBT90s is pretty impressive though; plenty of time to scan an area without worrying about the light stepping down too quickly.
