Optics

• Multi-optic 600mm square LED module that utilises intermediate brightness zone technology through application of flat centre strip and innovative curved wings
• The unique optic design creates a graduating light output from the centre, out to the sides, and then onto the ceiling plane. Thus eliminating harsh contrast created by flat panel LED modules. TSI technology is also incorporated to achieve optimum wall illuminance for education
• ‘Cool’ white 4000K colour temperature
 
Two optic options:
1. Advanced Hexaprism PMMA centre optic with prisms facing down for optimum glare control and diffusion
   • Designed for use in offices or school classrooms where LG7, LG5, and/or UGR compliance may be required
   • Outputs:
 – 2700 lumens, 26W
 − 3350 lumens, 33W
 – 4100 lumens, 38W
 
2. Polycarbonate TP(a) opal micro-polymer diffuser with wipe clean finish
   • Designed for use in transitory, social spaces and open areas
   • Outputs:
− 2200 lumens, 22W
− 4200 lumens, 40W
– 5300 lumens, 49W
