The Westcott Ice Light 2 LED light is an enhanced version of its predecessor built on the wish lists of photographers in the field. As their first order of business, Westcott made the light 50% brighter while maintaining its 21.6 x 7.5" form factor and rendering color-accurate output with a very high CRI of 96. Ten-step dimming is accessed via the unit's handle which has a built-in digital display. The light also has a USB port and built-in Bluetooth technology for future wireless control. For videographers, Westcott has doubled their efforts to produce a truly flicker-free fixture. A removable Lithium-ion battery is yet another Ice Light 2 refinement. A 2.5-hour charge gives you 60+ minutes of runtime with the convenience of being able to charge a backup battery outside of the fixture. You can also double your runtime by attaching an optional power pack battery extension. It uses the same charger as the Ice Light 2. Like Its predecessor, the Ice Light 2 is virtually heat-free. Hold it as close as you want to your subject; the closer you get the more Ice Light's wrap-around quality of light becomes evident. Since it's virtually heat-free you never have to worry about injuring the talent or damaging the set. While the ergonomic shape easily lends itself to handheld operation, the Ice Light 2 has a 1/4"-20 tap at each end of it for mounting it to a light stand or other accessory.
