FacetCore™ LED light source uniformity demonstrated with LTI Optics Photopia™

Oct. 22, 2021
LTI Optics Photopia optical design software predicts FacetCore’s 360° uniformity.

ST. PAUL, MN, October 22, 2021 - MetroSpec Technology’s custom FlexRad® FacetCore™ radial LED light source illuminates with exceptional radial light intensity and light uniformity.  LTI Optics Photopia™ optical design software quickly provides accurate optical design simulation of diffuser and source combinations. Come see FlexRad modeled with Photopia at the LTI Optics booth at LightFair in New York, October 27-29, 2021.

FacetCore can be cut from a reel to exact fixture specifications as a flat, bendable wrap, or formed into a pre-configured multi-sided shape. With brightness up to 4,000+ lumens per foot, FacetCore fits into a wide arrange of pendants and sconces including globes, tubes and cylinders.  No additional heat sink is required.

“FacetCore looks nice and the radial board layouts work well for cylindrical products. This pre-configured light source is a more cost effective option than what we have seen, and it’s nice FacetCore can be cut to any length", said Mark Jongewaard, President - LTI Optics.  LTI Optics are optical design consultants and developers of Photopia™.
