Description

The CB4000PB-RC is a compact video light from Bigblue’s CB line. Its chip-on-board (COB) LED puts out 4000 lumens of 5000K warm white over a 120° beam with no hard edges, and Bigblue lists a color rendering index (CRI) of 85. Run two of them and you cut down on shadows.

Four white levels run from 4000 down to 2000, 1000 and 400 lumens, for 1.5 to 15 hours of burn time. A lighted battery level indicator shows what’s left. Built-in red LEDs give you a discreet light for watching nocturnal marine life without disturbing it, and blue LEDs add a third color with three power levels.

“RC-ready” means the light has a port for a fiber optic cable. Add the cable and a controller arm, sold separately, and you can run the light from your camera tray. One controller arm runs two lights, and a two-light setup needs two fiber optic cables. Want the remote in the box? Look at the CB4000PB-RCP.

Power comes from a rechargeable 18650 x 3 battery pack, and Bigblue suggests 5–6 hours to charge it. The housing is anodized aluminum, 50 mm across and 130.3 mm long, tested to 100 meters.

A Goodman glove and a 1-inch ball mount come in the box, along with the charger and a dry bag.
