ETC Source Four 36 Degree:
This is the ETC Source Four 36 Degree lens attachment, not the fixture itself.
A complete rethinking of ellipsoidal technology, the ETC Source Four 750w is the only fixture combining the energy-saving power of the HPL lamp with the patented dichroic reflector for the coolest beam on the market. That means your gels, patterns and shutters last longer, and your performance space stays cooler. No other light offers such optical brilliance. 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, 26º, 36º and 50º field angles makes the Source Four even better for ultra-crisp, high-contrast gobo projections. Rated for 375, 575 or 750 watts, the Source 4 is perfect for punching through saturated colors and providing the longest throws. Ultra-efficient for more lumens per watt: at 575 watts the Source Four literally outshines other 1000W ellipsoidal fixtures. And at 750 watts, well, no point comparing – there are no other fixtures in its class. When fitted with a 750 watt HPL bulb (available separately), this fixture will provide a beam of 349 foot-candles 9.5 ft (2.9 m) in diameter, from a distance of 10 ft (3 m). It will throw 56 foot-candles 23.8 ft (7.1 m) in diameter, from a distance of 75 ft (22.7 m).
