Basic parameters
Model: HMB-J03-36
Product introduction: Recessed integrated flat prismatic classroom light, simple and elegant in design. The entire luminaire adopts a spray-coated high-temperature baked paint surface treatment, featuring anti-aging and non-discoloration properties. The frame is made of stretched integrated aluminum profile, and the back housing is formed by one-piece stamping of 0.4MM high-quality steel, with no weld spots, no burrs, stable structure, and good product consistency. High-gloss baking paint treatment provides good reflection effect and is not prone to aging or discoloration over long-term use. The product has good dustproof performance and is easy to clean. The light source adopts aluminum substrate SMD, fixed with thermal conductive adhesive. It features good heat dissipation, and the light source is not prone to lumen depreciation over long-term use.
