The 31.8 x 33.0 x 6.3 cm panel draws just 110W of power while it outputs the equivalent of a higher rated tungsten fixture and maintains a high CRI of 95. Under normal working conditions the Superpanel's fan is barely perceptible but it can be turned off for passive heat dispersion and silent operation in sound-sensitive environments. A multi-voltage AC adapter is included, and it can also run on an optional separately available dedicated battery for up to 1.7 hours when mains power is unavailable. Strong yet lightweight, the Superpanel 400 features a durable carbon fiber reinforced techno polymer shell that weighs just 2.27 kg.
