Basic parameters

Model: HMB-B01-38

Product introduction: Integrated grille anti-glare classroom light, simple and beautiful in design. The entire light adopts spray-coated high-temperature baking paint surface treatment, featuring anti-aging and non-discoloring properties. The frame adopts stretched integrated aluminum profile, and the bottom shell adopts 0.4MM high-quality steel stamping integrated molding, with no weld points, no burrs, stable structure, and good product consistency. High-gloss paint treatment provides good reflective effect and is not prone to aging and discoloration during long-term use. The product has good dustproof performance and is easy to clean. The light source adopts aluminum substrate SMD, fixed with heat dissipation adhesive. It features good heat dissipation effect, and the light source is not prone to lumen depreciation during long-term use.
