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 reply and the link. I’ll check it out.
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.
Sent PM with title amazon SP 35 code please, and thank you as the body message….It’s no problem was the response,but that is all…no code…unless it’s no problem is a code. I still need a SP35 code for Amazon in the US.
