With the ETC Source Four 25-50° Zoom Ellipsoidal Spotlight only one fixture is needed for a variety of field angles. ETC’s patented one-handed zoom operation makes adjustments quick, simple and safe. A technician can focus with one hand and hold the ladder with the other. The lens-tube door provides quick, tool-free access when cleaning the lens assembly.
This Black, Edison Plug model has all the advantages of the revolutionary fixed-focus Source Four: bright, even field, cool beam, and amazing efficiency. The patented dichroic mirror disperses heat; shutters and accessories stay cool. Drop-in accessories are interchangeable with the fixed-focus
Source Four models. Other models in this and the narrower 15-30° zoom range are available:
Pigtail, 15 and 20 Amp Twist-Lock, and Stage-Pin.
