Using a patented technology, according to the firm, it is achieves the narrowest available beams combined with state of the art colour mixing capabilities.

“Designed to match most demanding RGBW or human-centric light applications, it also provides a significant breakthrough with single or multi-chip white LEDS,” sias Gaggione. “Combined with quad chip white LEDs, it eliminates the cross-hair effect usually associated with narrow beams.”

The collimators are:

• LLC59U
  As low as 5.7° FWHM with 4mm² RGBW leds
  <4° FWHM with some white leds*,
• LLC59N – “Bringing the stage lighting application to the next level”
  6.2° FWHM beam with 4mm² RGBW.
• LLC59C “Uncompromised colour mix for architectural or indoor coloured beams”
  <10° FWHM.

*3.9° with Seoul Z5, 4.0° with Osram Oslon SSL 150

FWHM is full width to half maximum intensity, so 4° FWHM is a +/-2° beam.
