LED classroom light - grille anti-glare

Q: How many watts are enough for classroom lights?

For a standard classroom (≤64㎡), the common setup is 9 units of 36W classroom lights plus 3 blackboard lights. The maintained average illuminance on desk surfaces is ≥400Lx, illuminance uniformity is ≥0.7, and lighting power density is ≤7W/㎡.

Q: What standard must classroom light anti-glare meet?

The unified glare rating (UGR) for classroom lighting must be less than 16. HUMUBAO HMB-H08-36 uses an optical grille for anti-glare, with a measured UGR<16, effectively preventing glare interference for teachers and students.

Q: What color rendering index do classroom lights need to be eye-friendly?

This classroom light features a color rendering index of ≥98, a special R9 value of ≥90, a color fidelity of ≥90, a color temperature of 5000K±100K, and a blue light hazard rating of Rg0 (exempt/no risk).

Q: What should be done if the classroom light has severe flicker?

Choose luminaires that are hazard-free and have no noticeable flicker, and refer to IEEE Std 1789-2015; HUMUBAO HMB-H08-36 uses an isolated constant-current driver and meets the flicker requirements of that standard.

Q: How long do classroom lights generally last?

The whole luminaire has a lifespan of ≥30,000 hours, with a lumen maintenance of ≥97% at 6,000 hours, showing minimal light decay over long-term use; this product comes with a 5-year warranty and a Class II electric shock protection rating.

Basic parameters

Model: HMB-H08-36

Product introduction: Integrated grille anti-glare full-spectrum LED classroom light, uniform light output, precise light output angle. The entire lamp is formed in one piece from extruded aluminum profiles, with a sandblasted and oxidized surface. Both end caps are made of PC injection molding, and the lens and light source module are embedded in the guide grooves of the lamp body. It has advantages such as a sturdy structure, good heat dissipation for the light source, low lumen depreciation over long-term use, and long service life. Optical grille anti-glare is used to avoid 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.
