The LM-P40Bi is designed for creators who need more powerful lighting in a portable package. Its 40 W output helps illuminate interviews, product shots, streaming setups, or small stages without the need for a large studio light.
The dual-color temperature range of 2700–6500 K allows you to quickly match the light to both warm indoor lighting and cooler daylight. Dimming from 1–100% gives you control over the intensity, and the high CRI of 96+ helps preserve the natural colors of skin tones and products.


The built-in 37 Wh battery enables cordless operation. At full power, it lasts approximately 35 minutes; at 50% brightness, approximately 1 hour and 20 minutes. The light can be quickly charged via USB-C PD and, with a compatible charger, used while charging.
The LCD display makes it easy to adjust brightness and color temperature settings. The magnetic diffuser softens the light for portraits and talk-to-camera shots, while a pair of 1/4" mounting points allows for attachment to a tripod, arm, or other rigging accessories.
