These LED panels can add “hot swap” capability: pull out depleted panels and quickly exhchange for fully charged ones. You may also need more to replace lost/damaged LED panels. These are compatible with VPR 400 series. To fully equip a single VPR, you will need to order two (2) panels. One charge will provide 1-3 hours of light, depending on your dimmer settings. Adapters are included to mount the LED panel on the hotshoe of your video camera, SLR or tripod.
Please be sure you are ordering the correct LED panel. The VPR 400 panel has a sliding on and off switch and three power level LED’s.
