The Altman ODEC is the first fully functional outdoor ellipsoidal with 30°-55° zoom focus, framing shutters, glass or steel pattern projection capabilities, internal & external mounting options for color media, dual gobo rotator, mechanical douser, louver, or scroller. The removable lid allows for maximum accessibility during installation, lamp changes or lens adjustments. Two stainless steel safety cables hold the lid securely when the fixture is opened. The lid is secured to the body with four side-mounted link–lock latches that provide a water-tight seal. Padlocks of appropriate size can be added for security. The proprietary highly polished reflector is engineered for use with T6 G12 CDM/CMH lamps for maximum output. The lens focus adjustment is via Teflon guides throughout the focus range. Focus is secured by way of brass thumb screws. The ODEC comes complete with pattern holder, image clarifying donut, and internal color media holder.
Use this calculator to determine either the size of the circle of light, how far away you should place the light, or which degree of lens you should use. Put in two of the values and then hit calculate to find the third value.
Values can be in feet or meters, but both values must match.
