Offering more power than a traditional 500 watt tungsten unit, the 750 watt meets with the demands of professional studio based photographers. It can also be used at 250 watts or 500 watts by simply flicking a switch on the back panel. The lamps are color balanced to 3200k enabling them to be used with many other Interfit tungsten or halogen lighting. This light comes complete with a Interfit Stellar 750 X Tungsten Head with 3 x 250w Lamps.
