Features (2) Astra 6X BiColor LED Lights and Stands in an easy to Travel Case. Simple to use, just power them up and dial between tungsten 3200K to daylight 5600k color temperature for a perfect match. Astra's have a built in dimmer for getting the exposure just right. It couldn't be any easier! Best of all, because they use LEDs, they require only 110 watts to power both lights. Need to power them with a battery? The included V-Mount adapter plate accepts pro grade Sony camera batteries. This makes a great light kit for interviews or product photography. How do the Astras compare to other light sources? In daylight mode they have comparable output to a 575w HMI and in tungsten mode to a 2000w softlight.
