$300.00 100W Halogen flashlight seems impressive.
1500 mAH 14.4V battery pack, max available energy is 21.6 WH.
0.216 Hours run time per charge.
12.96 Minutes of light if no waste incurred in battery heating, etc.
Their 15 minute claim is an exaggeration. LOL
status with under 13 minutes of light per charge.
Perhaps if one was to backpack a golf cart battery or two, plus a 100W inverter???
I'll stick to my 3W LED MAG Light.
