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. Illumination is 1800 lux at 3200K at 3.3 ft distance.
