The EXC-JH11B is an ultra energy-efficient, eye-friendly LED classroom light designed as a modern replacement for traditional chalkboard fixtures. Its highly optimized structural design enhances heat dissipation, contributing to a longer operational lifespan and greater reliability over time.
This fixture utilizes high-luminous-efficiency, full-spectrum SMD2835 LEDs combined with a professional optical lens system. The result is a soft, uniform light output that mimics the spectrum of natural sunlight—providing gentler illumination that helps protect students’ eyes and reduce visual fatigue during extended use.
Featuring a unique three-row lens configuration paired with an optical anti-glare grille, the EXC-JH11B ensures exceptional light uniformity while minimizing distracting glare. Its built-in constant-current driver is compact, making installation straightforward and efficient. The driver also ensures instant start-up with no flicker, contributing to a stable and comfortable lighting environment.
Technically, the EXC-JH11B operates on AC220-240V with a power consumption of 36W and a high power factor of ≥0.95. It delivers a luminous flux of 3000–3600 lumens with an efficacy of over 90 lm/W. The CRI exceeds Ra 95 with R9 > 90, ensuring full-spectrum color rendering ideal for educational settings. Color temperature options include 5000K, 4000K, and 3500K, all with a color tolerance of ≤3 SDCM. With a blue light hazard rating of RG0 and a flicker depth of less than 1%, this fixture prioritizes visual health and comfort.
Additional features include anti-glare body design, beam angles of 82° (C0-180) and 25° (C90-270), blackboard surface uniformity greater than 0.86, and an IP40 rating to protect against dust and insect ingress. Constructed with an aluminum profile housing and plastic end caps, the EXC-JH11B measures 1230 x 87 x 80 mm and is designed for pendant mounting.
