LED classroom light

Q: How many watts does a classroom light need to be sufficient?

36W is enough to meet the needs of a standard classroom. The HUMUBAO HMB-H02-36 has a rated power of 36W. With a layout of 9 classroom lights plus 3 blackboard lights, the maintained average illuminance on the desk surface is ≥400Lx, and the lighting uniformity is ≥0.7.

Q: How effective is the anti-glare performance of the classroom light?

This light has a unified glare rating of UGR<16 (measured in classroom lighting). It features an integrated grille anti-glare design, a blue light hazard classification of Rg0 (exempt), and flicker-free operation, making it suitable for primary and secondary school classrooms.

Q: What are the color rendering index and color temperature of the classroom light?

Color rendering index ≥95, special color rendering index R9 ≥90, color fidelity ≥90, color temperature 5000K±100K, color tolerance ≤5, able to faithfully reproduce the colors of books and blackboard writing.

Q: What is the lifespan of the classroom light, and how many years is the warranty?

The overall lamp lifespan is ≥30,000 hours, with a lumen maintenance rate of ≥97% at 6,000 hours. The light source resists lumen depreciation over long-term use. The product comes with a 5-year warranty.

Q: What are the installation method and protection rating of the classroom light?

It uses rod suspension installation with a rod diameter of Ø10MM. The IP protection rating is IP40, and the anti-electric shock class is Class II. The overall lamp is made of metal, with a stretched aluminum profile frame and a 0.4MM cold-rolled steel plate one-piece formed bottom shell.
