This flashlight uses a 60-watt high-powered H4 quartz halogen bulb that produces 1,100 lumens and natural daylight illumination at a color temperature of 4,300 Kelvin, brighter than tungsten photofloods used by professional photographers. The rechargeable battery provides up to 80 minutes of operation on a full charge in full power mode. The hardened glass chimney adds strength along the length of the bulb for extra shatter-resistance, and a hardened glass lens surrounded by a latex rubber sleeve shields the bulb chamber. With adjustable stand and carry handle. Battery recharges via included AC adapter or 12-volt DC automobile adapter. 15 1/2" L x 12" Diam. (12 lbs.)
