Powerful lighting for location work and compact studios
Pocket-sized COB light with up to 50W output
The L023 combines small dimensions with enough output to serve as a key or fill light in a compact setup. It operates at 40W in normal mode, while Overclock mode raises output to 50W when extra brightness is required. With the included reflector it reaches up to 13,150 lux at 0.5m.
Fast, direct control
Brightness is continuously adjustable from 0–100%, while color temperature covers 2500–6500K. The rear display and control dials provide immediate access without an app. Eight preset lighting effects add creative options for cinematic scenes.
bi-color COB source with CRI ≥95
wide 120° beam angle
stepless dimming and eight scene effects
Mini Bowens for soft and shaped light
The integrated Mini Bowens mount accepts the included reflector or diffusion dome in seconds. This makes it easy to adapt the light for interviews, product photography, vlogging and location work. A 1/4"-20 thread supports mounting on a light stand, bracket or pistol grip.
The light itself weighs only 490g without reflector, so it fits easily into a compact kit and can also be handheld for short periods.
Built-in battery and flexible charging
The 14.8V / 3400mAh (50.3Wh) battery provides up to 50 minutes at 50W, at least 70 minutes at 40W and up to 180 minutes at minimum brightness. Charging is available through DC 19V/3.4A or USB-C PD up to 65W, with a full recharge taking approximately three hours.
When powered and used simultaneously, maximum output is limited to 40W. A compatible 65W PD charger and cable are required for full charging speed.
