Source Four Enhanced Definition Lens Tube (EDLT)

What is Source Four EDLT? EDLT stands for “Enhanced Definition Lens Tube”. The EDLT offers heightened contrast and edge crispness to projected images, specifically when the Source Four is used as a gobo projector. This is an optional lens tube for the Source Four, it is not the entire fixture.

What’s so innovative about the EDLT? The EDLT’s new dual a-spheric lenses utilise the most advanced manufacturing techniques and anti-reflective coatings. The system is optimised for sharp focus of intricate gobos with maximum lumen output.

Why is the EDLT an option rather than standard on all Source Fours? EDLT’s advanced optical system costs more to produce and is not required for most lighting applications. But when the lighting situation calls for even more precise projection optics, EDLT is available! Remember, millions of Source Four products are in the field and remain the benchmark for luminaires, still setting the standard for performance and price.

Is there any loss of light output associated with the EDLT? No, in fact, preliminary photometric tests show that the EDLT produces a gain in field lumens, along with improvements to contrast and acuity.
