This is the new XM-L2 LED version of this flashlight, the info listed is from the older XM-L version. The flashlight with the new emitter will be about 15% brighter than the older model.
SL6S series flashlights are simplified version of SL6,which inherents all the main features of SL6 series but cancelled the tailcap switch and inner tube.
Please note that high quality 18650 batteries are required to access and maintain the turbo mode of this light. 2 CR123s will likely not power turbo mode and many the protection circuit of many protected 18650s will kick in when the light is switched to turbo. Two batteries that we have tested and confirmed to power the turbo mode are the Eagletac 3100 mAh 18650 and the AW 2900 mAh 18650.
