Used Anton Bauer UltraDAYlight 5600°K HMI Head Module for the Ultralight 2 Video Light.

UltraDAYlight HMI Head Module... With UltraDAYlight the high efficiency of HMI lighting can be added to any Ultralight system by simply changing head modules - a patented Ultralight exclusive.

The UltraDAYlight head module fits any Ultralight base to instantly deliver 5600°K light at less than half the power required of tungsten/halogen - without the need for dichroic adaptors.

Uniquely designed to share power from camera battery using the PowerTap on every camera Gold Mount.

Instantly change from daylight to tungsten and back by swapping head modules - no twisting, turning orhandling of bulbs. And since the rugged Ultralight head modules house and protect the bulbs, they can be stored in the head module until next use.

The UltraDAYlight head module is a unit - 25 watt bulb and ballast all in one. Perfect for daylight fill situations, the UltraDAYlight can be converted to tungsten with the UL-GF and UL-GELKIT (not included).

UltraDAYlight also features a unique color temperature adjustment which allows the ballast to adjust the color temperature of the light, compensating for bulb variations and aging. Specifications: 5600K nominal color temperature. 350 footcandles at 3 ft (1m), 25 watt ballast.
