Source Four's revolutionary technology gives you a clean white beam for unequaled imaging, crisp pattern projection, and a bright, even field. The EDLT lens tube option for 19º, 26 º, 36 º and 50 º field angles makes the Source Four even better for ultra-crisp, high-contrast pattern projections. 
 
 Rated for up to 750 watts, the Source Four is perfect for punching through saturated colours and performing the longest throws. Ultra-efficient for more lumens per watt: at 575 watts the Source Four literally outshines 1000W ellipsoidals. And at 750 watts, well, no point comparing - there are no other luminaires in its class.
