APL-PB-2508D

Brand L.I.O.N
Product origin China

Φ120-300mm sizes (18W-48W). Bezel-free design achieves near 100% active area. Die-cast aluminum housing ensures superior heat dissipation. 90-100lm/W efficacy, CRI>80. AC100-265V input. IP44 rated diffuser. CE/RoHS/DLC certified. Ideal for offices/retail spaces.

I. Optical Engineering Breakthrough

Bezel-Free Illumination Technology

Near-100% Active Area: 1.5mm ultra-narrow bezel achieves 98.7% light-emitting surface ratio (vs. 85% industry standard)
Edge-to-Edge Brightness: Patented light guide plate (LGP) with laser-etched micro-dots eliminates dark borders
Glare Control: UGR<14 via prismatic diffuser + micro-louver layer (EN 12464-1:2021 compliant)

Core Innovation:

Zero frame shadow effect at 170° viewing angle
92% uniformity (CIE 150:2017)
