Stand aside… this rechargeable flashlight will light a construction site, backyard or campground at 3000 powerful lumens – and all in a handheld flashlight. We’ve upgraded and updated this light with a 200% improved run time (up to 40 hours!), a rechargeable Safety Ytrion Cell battery, and a Fast Action Switch for quickly moving between light functions. The seven reflector lenses were newly recalculated in conjunction with all-new LED chips for a more homogeneous lit area and better light distribution. The X21R.2 puts most car headlamps to shame.
