There's no apparent difference because the bins are made in the same process unless you have the equipment to remove the LED and drive it at a constant current in an integrating sphere. They don't make bins separately. They make a bunch of XM-L2s and then they test them (that's the binning...
Things I don't see use the LED flash as a flashlight doing that a dedicated light can do as well anytime soon:
-Throw . Till someone invents a way to directly shape the beam (and I want flying cars first :devil:) a reflector or lens takes real estate that doesn't fit the ergonomics of a phone...
Generally with lights I am of the less is more group.
There are lights where extra thermal mass makes sense but for the most part don't need to "blot out the sun." Balance matters but generally the only clue to that would be a review. Nothing about a listed weight tells me how they...
Flashlights make light... why do we see so many variations and differences. Why does GM make anything besides one model?
Aside from the protection circuit differences there are plenty of reasons to have different performing cells even from the same manufacturer. They supply them to different...
Re: $11 single AA/14500 XPG R5 450 lumen flashlight ???
An R5 binned XP-G lists a calculated 348 minimum lumens at 1 Amp (with a typical forward voltage of 3,15.) Many budget lights claim emitter lumens (What's right there coming off the emitter as opposed to what actually comes out the...
I don't prefer reflective material as a rule so it's a no. It's useful. I tend to prefer more muted tones in much of my clothing so unless the use is specifically one where I would always want to have it I avoid it. I do have a number of reflective belts that can easily be slung over a...
Chris - If there was any snarkiness it was strictly aimed at the MSM. They love to play to fear and our generally bad ability to assess risks because it gets attention...which means viewers and readers. It WOULD suck to have a phone rapidly combust in a pocket. It would suck to get hit by a...
Looking at Sales numbers just for the S3 they'd surpassed 40 million phones sold in Jan of this year with over 100 million total S series phones sold. Obviously it's not a complete report of all phones sold that may have had a rapid burning of the battery with serious results. What info the...
A little bit of test data (admittedly with a small sample size of 1) gives some insight past the assumptions. From another forum the bond wires of an XM-L2 (mounted on copper Sinkpad with good heatsinking) fried over 8A (about 5.3C draw on 123s). At that point it's only got a Vf of 4.2 volts...
You'd need to get more than half the total current going to one of the LEDs. That's likely to take one LED below typical Vf and the other 3 all being very high. Unlikely you'll end up with that condition. There's less of a difference between typical and maximum for XP-G2 versus XP-G (at 350mA...
It depends. In Army speak the universal answer is METT-TC (Mission Enemy Time and Troops available - Civil Consideration) dictates is the "right" answer to all such questions.
It really depends on a lot of different factors. There's no one right answer for "the battlefield." One friend I...
I rarely buy the hot new thing on Day 1 or pre-order. Rarely is there not at least some difference between reality and marketing. In the flashlight market, especially, the hot new thing also tends to turn the first owners into the last round of beta testers.
subsribed to wait for that answer. I once saw an interesting history of the evolution of the current iteration of the light going back to WWII. IIRC the last "major" change was post or during Vietnam. I suppose that means there could be old versions that are different out there. Those would...
