Basic parameters
Model: HMB-J03-36
Product introduction: Recessed integrated flat panel prismatic classroom light, simple and elegant design, the entire light adopts spray-coated high-temperature baking paint surface treatment, with anti-aging and non-discoloring characteristics. The frame adopts stretched integrated aluminum profile, the bottom shell adopts 0.4MM high-quality steel stamping integrated molding, no weld spots, no burrs, stable structure, good product consistency. High-gloss paint treatment, good reflection effect, not easy to age and discolor during long-term use. The product has good dustproof effect and is easy to clean. The light source adopts aluminum substrate SMD, fixed with thermal adhesive. It has good heat dissipation effect, and the light source is not prone to lumen depreciation during long-term use.
