For those using flashlights that take the P60 drop-in LED modules as headlights or flashlights this may be of interest. Many flashlights from Solarforce, Surefire, Dereelight and other vendors take these LED modules.
Thrunite now is shipping a XM-L LED P60 upgrade LED module that is putting out about 460 OTF lumens. Floody beam and quite bright. I got the module from Sbflashlights.com and the cost was about $30 including shipping. I got the 3 to 9 volt 3 mode module version. This is a very efficient LED which in the Thrunite drop-in draws 1.5 amps maximum at nominal voltage so heat buildup should not be too bad. I checked the module temperature after 15 minutes of running and the temperature was just a bit above my body temperature.
