DLED7-Bi, is a 90w Bi-Color Focusing LED Source with Similar Housing to the Dedolight DLED4 (40 W). 

Although DLED7 heads provide significantly higher light output, and in spite of the added cooling devices, the weight of these light heads is still identical with the original DLED4 light head.

Only the Power Supply/ Dimmer has grown somewhat, to accommodate the increased power. Alternative power supplies allow battery operation. The bicolor version is continuously adjustable from 2700K all the way to 6500K. Pure monocolor DLED7 versions in daylight or tungsten are also available. The noise level of the whisper cooling will surprise you – even under the most critical conditions.
