Well shoot, not sure how I missed that. Nice work! A bit disappointing results, but hey… not all LEDs can be homeruns for flashlight use.
From your images, would not the xd16 have a 19.5% higher lux in a 20 mm edc single 1850. Driven by a single amc7135 at 350mA, the xpl/xml typically only gets a near sighted 1100cd, not enough to bounce around in day working where detail and texture is important (cars, drywall, painting inside, etc.). The xpg might get something like double, say, 2200 cd. This is better, but not the ideal lux.
I would gladly take an extra %19.5, 429 lux, in an edc on a workday run-time setting.
I would bet the better output to throw balance would be the Xp-G2 S4 HE 180Lumens @ 350ma XPGBWT-BE-0000-00L50. However, I don’t see a single post at anyone testing these. It used to be people would drop these into lights and post the beamshots within a month of release. I am guessing since current has gotten so high, people’s camera’s don’t have time to get into focus before the battery runs out.
Given the fact that it does not have an isolated thermal pad, I would be concerned that over driving it may not be an option. Otherwise, could be interesting in the A and D bins.
The Virence boards for the E21A are thermally as good as a DTP board.
It was hoped that this led would outperform the dedomed XP-G2 as a thrower led, but even though the led was not tested by one of the BLF led testers, the few builds that are reported had disappointing throw.
Examples (thanks to the Search feature!)
- Cree XD16 measurements
- pointless mods: a high CRI lighted tail (bonus: Cree XD16 test)
- Pocket sized with most throw? - #54 by Cereal_killer (just a mention, you would need to ask for details)
- 2.4A Driver for XP-E2 - #34 by Cereal_killer (another post by CK, no details but at least there’s a pic)
- What did you mod today? - #6114 by Cereal_killer (yet another post by CK with a pic, a few details included)
