Being simulate natural light the SUN series can be used with flash or natural light.BL-3000SUN,the new model continuous lighting(three flash heads and a travel-generator)with all the excellence of both tungsten lamp and flash lamp. High precise stabilized circuitry (operating voltage:AC100V-240V,50-60Hz),apply to any power supply all over the world,keep the consistent 100% light intensity output even if the voltage largely fluctuate.Because of visible continuous lighting,it is convenient for precise adjustment,no parallaxa.It adopts OSRAM bulb and advanced import circuitry low heat lamp, consistently keep the normal temperature after long working time.
