The Quasar Science Q-Lion Q20 Switch Linear Universal LED Light (24") is a portable, battery-operated, 24" bi-color LED tube light, useful for creating fill and accents in both still imaging and video-based applications. It is a compact turnkey lighting solution, serving as a toolbelt staple for set lighting technicians, camera teams, art departments, and independent online content creators alike. It is great for lighting everything from actors to craft services, especially when space is at a minimum.

Compact and lightweight, the Quasar Science Q-Lion Q20 Switch Linear Universal LED Light (24") may be mounted via the 3/8"-16 socket or simply stuck in place on metal surfaces with its magnetic base. This LED light features single-button operation and the button is recessed to prevent accidental setting changes.

Integrated Rechargeable Lithium-Ion Battery

The integrated lithium-ion battery can operate the Q20 linear LED for up to 4 hours at 100% output. The built-in battery level indicator allows the remaining charge to be monitored. The rechargeable battery is charged with the included multi-voltage AC charger via a micro-USB port, and the lamp may be used while charging. Note: the light will not charge on a standard 5V USB charger. The light features a kill switch to disable battery operation for travel.

Stepped Dimming for Quick Operation

Scroll through preset output levels of 100%, 75%, 50%, 25%, 10%, and off for quick and easily repeatable setups. Output is flicker-free below 1/500th of a second at any output level, and 1/2000th of a second at maximum output.
