The Switronix TorchLED Bolt 220W On-Camera Light has a 220-watt output and was improved for convenience. The new LED light now has an independent knob for color temperature between tungsten (3200k) and daylight (5600k) that means you no longer need to mix and match between two dials for the most accurate ambient light. The dial is used to change the brightness from 0% to 100% with no noticeable color shift.
The BT220 is the same size as original Bolt BT200, but 10% brighter and 40% more power efficient, which means it will run longer on the same Sony L-series style batteries or with on-board batteries through the powertap cable included.
The powertap cable is used for DC powering off of a standard 14.4v brick battery, as well as a built-in Sony L-series battery sled. With the convenient on/off switch, you have the ability to maintain your light settings even when powering off the unit.
