Emisar DW4 review by LuxWad >>> (163) Emisar DW4 - Rambling Review - YouTube

Emisar DW4 puts a high lumen output but generates a lot of heat at the same time, please acknowledge before purchasing. Unprotected, flat top battery works only (not included in the price), DW4 does not work with protected battery.

The boost driver upgrade is available for the quad version of XP-L HI, SST-20(except SST-20 deep red), Osram W1/W2, Nichia 219B R9080 versions, each LED receives 2A current. The driver is not compatible with Nichia E21A, Nichia E17A, and mule versions of the flashlight.

Please be noted that the boost driver version will have less output on turbo than the regular version, it is a more efficient driver (90-95%) with longer running time and less heat.
