L-Tech 20W 300-650mA CC Triac LED Driver

Description

Intelligent constant current LED driver. Supports Leading edge (Triac), Trailing edge (ELV). With soft-on and fade-in dimming function, enhancing your visual comfort (see video below). T-PWM™ dimming technology allows for continuous and flicker-free images under high-speed photography.

The housing is made from V0 flame retardant PC materials from SAMSUNG/COVESTRO. Small size and light weight. The clamshell design and screwless type for strain-relief. 

Dimming
