The KingLite is a heavy duty, high powered spotlight packed with features. It uses a unique dual filament Xenon lamp that produces a bright beam that cuts through thick smoke, fog, and dust. The body is made of unbreakable ABS resin with a polycarbonate lens and thermoplastic rubber shroud that resists chemicals and corrosion. Two reflectors are included: a modified spot (stippled for a wide beam) and a laser spot (smooth for a tight collimated beam). Also, a back-up lamp is stored behind the reflector for emergencies. The dual direction switch is easy to operate, even with thick gloves. And there's a locking slide feature to prevent accidental activation. The pistol grip/lantern handle quickly converts to multiple positions for flexibility. The 4000 also comes with a shock absorbing internal battery module that protects both the cells and the lamp from hard knocks. Powered by 8 D alkaline cells.
