AliexpressThe Ulanzi L023 40W Pro is a bi-color COB continuous video light for video, photography and other controlled lighting work. Its colour temperature can be adjusted from 2500 K to 6500 K, allowing warmer or cooler illumination without changing the light itself. The selected variant is without charger: it includes no AC adapter and no light stand, so the buyer must provide a compatible power source and any required support equipment.
Power and light control
The light has a manufacturer-listed normal power of 40 W and a maximum 50 W overclock mode. The 50 W figure is not a promise for every power mode: the manufacturer states that operation while powered or charging through DC or Type-C is limited to 40 W. An internal 14.8 V/3400 mAh battery is listed, with DC 19 V/3.4 A and USB-C PD 65 W input options.
It is a continuous light rather than a flash or RGB fixture. The manufacturer lists a reflector and diffusion dome for controlling the spread and softness of the light. These accessories do not establish that a stand or universal full-size Bowens adapter is included, so check compatibility before purchasing additional modifiers.

Practical limitations and buying checks
- Supply a compatible charger or power source and cable; verify USB-C PD or DC requirements before use.
- Check how the light will be mounted and route cables safely around the shooting area.
- Allow for fan and heat considerations, especially during extended or higher-power operation.
- Do not rely on an unspecified battery runtime, recharge time, waterproofing or all-day operation.
- Confirm reflector, diffuser and modifier fit before adding accessories.
No PMCODE physical test is represented here, and no independent lux, CRI, colour-accuracy, runtime, recharge-time or silent-operation result is claimed. See the official Ulanzi product page for the manufacturer’s package and specification information.
