The Haikelite HK20 is an ultra-high-output searchlight engineered for demanding outdoor illumination, long-range visibility, and large-area lighting applications. Equipped with four SFY55 LED emitters, it delivers a manufacturer-rated maximum output of 180,000 lumens and a claimed beam distance of up to 1,750 meters.

Powered by an integrated 48,000mAh battery pack consisting of 12 × 21700 lithium-ion cells, the HK20 combines exceptional output with multiple brightness levels, stepless dimming, active fan cooling, and intelligent thermal protection.

Its 6063 aluminum alloy body, Type III hard-anodized finish, tempered glass lens, and T-shaped carry handle make it a substantial lighting tool for outdoor exploration, search operations, emergency preparedness, and other demanding applications.
