for those of you that own the DEWALT dw919 18V Cordless Flexible floodlight with a dead bulb and look for replacement try this first ... just unscrew the flashlight lens and look right inside the rim ... BINGO ! ... they should be a extra backup bulb right inside the flashlight ... I find this out the hard way after buy the replacement pack ... but if you have already kill both bulb then buy the 2-pack here while you can ... these be kinda hard to find ... and they probably will not last ... these work great so go nutz !
