Basic ParametersModel: HMB-H01-36N Product Introduction: Integrated anti-glare polarized lens blackboard light, uniform light output, precise light output angle. The entire lamp body is formed in one piece using extruded aluminum profiles, with sandblasted oxidation treatment on the surface. Both end caps 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.

Frequently Asked Questions

What wattage is suitable for a classroom blackboard light?

This HMB-H01-36N has a rated power of 36W, a rated luminous flux of ≥3500Lm, and a luminous efficacy of ≥85Lm/W. The maintained average illuminance on the blackboard surface is ≥500LX. For a standard classroom (≤64㎡), 3 blackboard lights are sufficient.

Is the blackboard light anti-glare?

Yes, it is anti-glare. An anti-glare baffle is provided in the line of sight, and an all-in-one polarized lens is used. The blue light hazard rating is Rg0 (no risk), and flicker is harmless, preventing glare interference for both teachers and students.

Which national standards does this blackboard light comply with?

Comply with GB 50034-2013 "Standard for Lighting Design of Buildings", GB 7793-2010 "Hygienic Standard for Day Lighting and Artificial Lighting for Middle and Elementary School", and GB 40070-2021 "Hygienic Requirements for Myopia Prevention and Control of Children and Adolescents' Learning Materials". Also hold CCC certification, energy-saving certification, and high-quality light environment certification.

What is the lifespan and warranty period of the blackboard light?

The overall lifespan of the luminaire is ≥50,000 hours, with a lumen maintenance rate of ≥99% at 10,000 hours and minimal light decay. The warranty period is 6 years. It adopts an isolated constant-current power supply for greater stability during long-term use.

How should classroom lights and blackboard lights be configured for a standard classroom?

For a standard classroom of ≤64㎡, the installation plan includes 9 classroom lights and 3 blackboard lights. The blackboard lights are mounted with telescopic rod suspension, with a rod diameter of Ø10MM. The installation angle is adjustable by ≥30°, and the position can also be adjusted to both sides.
