What is “ATR”? Is that the feature that prevents the light from stepping down on Turbo? And if so, is this a good thing, like I suspect? Or, is it potentially dangerous, because it leaves it vulnerable to heating up and destroying the light or burning something/someone?

Also, is this light comparable to the SC31 Pro? Is it as bright? Brighter?

If you, or someone else who’s familiar with this light, wouldn’t mind replying and sharing some feedback, I would appreciate it.

ATR is the abbreviation of Advanced Thermal Regulation. It is a safety mechanism to prevent the flashlight from overheating, i.e. damaging the LED, battery and - most important - your skin while holding the light in your hand.

SC31 Pro and SP35 both share the same emitter but are different in some details. SC31 Pro has a slightly more floody beam profile, uses Andúril UI, is more compact and comes with a FET driver. SP35 has a simplified, proprietary UI, benefits from the new 21700 form factor and comes with a constant current buckdriver. In terms of maximum brightness they will be about the same.

Thank you for the detailed reply and helpful information. I am a big fan of Sofirn flashlights (I probably have 10-15 of their lights in my collection right now) and I am happy to support them, so I am tempted to buy this SP35, as $24 would seem to be a great price.

How many flashlights does a "real man" need?

None, real men are not afraid of the dark.

Sorry for my delayed response… and thanks to others who have already answered your question.

Personally, I’m not a fan of the aggressive ATR with visible fluctuations in brightness levels that this unit is reported to have.

Between that and the 6500K color temperature, I must pass on this deal.
