With the introduction of Source Four LED Series 3, comes the next generation of lens tubes. XDLT takes your Series 3 fixtures to a new level of brightness – especially when used from the farthest distances. Reduced light leak, improved pattern projection, and near-zero chromatic aberration make these lens tubes a must-have for the largest theatres.
When your lighting situation requires precise optics for projecting images, gobos, and logos, the Source Four EDLT (Enhanced Definition Lens Tube) option is an invaluable addition to your fixture inventory. The EDLT attaches easily to any new or existing fixed-focus Source Four, Source Four LED, ColorSource Spot, or Source 4WRD luminaires. While increasing light output up to 22% over standard lenses, EDLT also provide heightened sharpness and stunning contrast to images when used as a pattern projector.
With the introduction of the iconic Source Four incandescent fixture in 1992, came a revolutionary set of lens tubes that have set the standard for quality around the world. The original Source Four lens tubes are only available from ETC and come in 5°, 10°, 14°, 19°, 26°, 36°, 50°, 70° and 90° field angles.
Maximum brightness, maximum field-angle flexibility. With Zoom lens tubes you only need one fixture for a variety of field angles. Plus, these lenses make it easy: ETC's patented one-handed zoom operation makes adjustments quick, simple and safe. Technicians can focus with one hand and hold the ladder with the other.
