Wonder how much smoke it will produce? And how long it takes to explode. Sounds more like some sort of grenade than a light.
27A for 9XM-L in parallel. What sort of cell can handle that? Not anything that'll fit in the 280mm length. Google Translate didn't help much here. At most it is long enough for 3x18650 in series. Which means 8A each from them! Better use good IMR's.
27V at 3A in series. Which would mean 7-8x18650.
If these are driven hard which I doubt this is an 80W device!
And if I read it right that's a US$450 device. Probably double that from the usual free shipping suspects.
I am not sure, but the same seller has this pill, with 4*SST-90 on a CSM360 module, I am not sure it is compatible with the same host, but it should also generate quite a lot of heat for winter.
Anyone else notice each picture appears to be a different light? 1 with 5 leds and 1 with 7 leds and 1 with a smooth reflector. Seems almost light bad photoshopping or something.
9 XM-L's in, what, a square inch? Yeah. Good luck with that. Unless they found some super-metal to use as the pill, it will be so freakin hot in about 13 seconds that the XM-Ls will burst into flames. In my light with 24 XM-L's, I had to add 4 pounds of aluminum with more than 450 sq. inches of surface area to even think about controlling the heat produced - and they're far more spaced out. Back of the napkin calculations suggest that 80 or 90 watts into 2 cubic inches of copper would yield a steady state temperature of about 300C - some heat is going to be dissipated by convection through the host, but I would still suspect 200+ C. I know I don't want that thing in my hand.
When LED's are 80% efficient rather than 10%, That will make a kick-ass-host. For now, it's just not practical.
