Basic parameters

Model: HMB-H02-36

Product introduction: Integrated grille anti-glare polarized lens blackboard light, uniform light output, precise light output angle. The entire lamp is formed in one piece using extruded aluminum profiles, with a sandblasted and anodized surface treatment. The end caps at both ends are made of PC injection molding, and the polarized lens and light source module are embedded in the guide grooves of the lamp body. It has advantages such as stable structure, good heat dissipation for the light source, low lumen depreciation over long-term use, and long service life. An anti-glare baffle is provided in the line of sight direction, avoiding glare interference for teachers and students during use. The installation angle of the entire lamp can be flexibly adjusted, and grooves are provided to allow adjustment of the installation position to both sides.
