The EXC-JH10B is a cost-effective classroom lighting solution specifically designed to deliver high uniformity illumination for writing boards. This luminaire combines performance and affordability, making it ideal for educational settings where visual clarity and eye comfort are essential. Its housing is constructed with a robust metal aluminum frame, formed through a mold-extrusion one-piece process, significantly enhancing impact resistance. The fixture features a clean, modern aesthetic with an aluminum anodized finish complemented by lemon-yellow PC end caps, creating a fresh and lively appearance that suits vibrant classroom environments.
Designed for both students and teachers, the EXC-JH10B incorporates a professional polarized lens that allows close-proximity installation to the writing board. This ensures consistent high-illuminance uniformity for students while drastically reducing direct glare for teachers—a thoughtful solution to a common challenge in classroom lighting. It utilizes high-performance 2835 LED chips with a high color rendering index (Ra >95, R9 >90) and full-spectrum output, ensuring accurate color reproduction and a comfortable visual experience. These LEDs offer high luminous efficacy and low light decay, with a blue light hazard rating of RG0 for enhanced eye protection.
The fixture includes a high power factor (≥0.95) and low total harmonic distortion driver that delivers flicker-free, efficient performance. Its light output waveform fluctuation depth is maintained below 1%, ensuring stable, smooth illumination. Rated at IP40, the EXC-JH10B is effectively sealed to prevent insect ingress, helping to preserve the longevity and cleanliness of the light body.
Key technical specifications include an operating voltage of AC220-240V, a power consumption of 36W, luminous flux between 3000–3600lm, and a luminous efficacy greater than 90 lm/W. The fixture is available in color temperatures of 5000K, 4000K, or 3500K, with a color tolerance of ≤3 SDCM. The optical design achieves beam angles of 82° (C0–180) and 25° (C90–270), while the blackboard surface illumination uniformity exceeds 0.86. The EXC-JH10B is designed for pendant mounting and measures 1230x87x80 mm, using aluminum profile materials and plastic end caps for durability and aesthetic appeal.
