The EXC-JJ04B is a high-performance educational lighting fixture designed to deliver low-glare illumination ideal for classrooms and other learning environments. This direct-lit grille anti-glare luminaire is engineered to provide balanced lighting with enhanced visual comfort, promoting a more focused and comfortable atmosphere for students and teachers.
Constructed with a robust metal aluminum frame formed through one-piece mold extrusion, the EXC-JJ04B offers excellent structural strength and high impact resistance. The back panel is made of eco-friendly plastic that is free from VOCs and other harmful substances, ensuring a safe, non-toxic, and sustainable lighting solution. With an IP40 protection rating, the fixture effectively prevents insects and debris from entering, thus extending its service life.
This luminaire features a sophisticated three-layer optical design that enables both upward and downward light transmission to brighten ceiling surfaces while minimizing shadows and glare. Light from the optical-grade lens is evenly diffused, then refined through a secondary diffusion panel, and finally treated with grille optics to further reduce glare. Users can choose from square, honeycomb, or galvanized grille options to suit specific application needs and aesthetic preferences.
Equipped with high-efficiency 2835 LED chips that offer a color rendering index (CRI) above 95 and R9 values over 90, the EXC-JJ04B ensures vivid, full-spectrum lighting with minimal light decay and no blue light hazard (rated RG0). The isolated driver system supports a high power factor (≥0.95), low total harmonic distortion, and flicker-free operation with light output waveform fluctuation depth of less than 1%, making it a visually stable and energy-efficient solution.
Operating at 36W, this fixture delivers a luminous flux between 3000 and 3600 lumens with an efficacy greater than 85lm/W. It is available in color temperatures of 5000K, 4000K, and 3500K to accommodate different learning environments. The beam angles are measured at 65° (C0-180) and 27° (C90-270), providing focused yet even illumination. With a blackboard surface uniformity greater than 0.85 and a pendant mounting design, the EXC-JJ04B offers both technical precision and installation flexibility. Its dimensions are 1230x115x106mm, making it a sleek and effective solution for modern classroom lighting.
