The Switronix TorchLED Bolt On-Camera LED Light is a 200W-equivalent light for attaching to the top of your camera - or (likely via an adapter) to a light stand for use as a "sun gun" on a set or on location. The 16-LED light is powerful enough to use as a fill light outdoors. The TorchLED features a brightness and throw (40-50') that put it in the range of halogen lights.
If it has a free Powertap output, you can use your existing 14.4V DC brick-style battery for powering this light - a Powertap cable is included. Alternatively, the TorchLED Bolt accepts a Sony L-Series-style battery to supply the needed power. Though it puts out the equivalent of 200W incandescent light, it draws just 22W at maximum light output. At 4100K, which is a blend of full 3000K and 6000K light, the illumination is 3800 lux at 3.3' (1 m).
