DB221 Modular Design LED Linear Light

DB221 is a multifunctional modular replaceable linear luminaire. The housing is constructed from high-grade aviation-grade aluminum, delivering exceptional structural strength, superior corrosion resistance, and outstanding thermal conductivity—ensuring long-term operational stability and significantly reducing post-installation maintenance costs. The optical system offers four tailored solutions: two downward-lighting configurations—high-transmittance PC diffuser or UGR anti-glare diffusion film and clear prismatic cover; and two upward-lighting configurations— high-transmittance PC diffuser, and bat wing-distribution clear extruded PMMA lens. These options enable precise adaptation to varying photometric and illuminance requirements across diverse applications. The luminaire is available in four standard lengths—600, 1200, 1500, and 2400mm—and supports five mounting methods: ceiling surface mount, pendant, wall-mounted, track and recessed, ensuring compatibility with a wide range of complex installation scenarios.

  • Modular design allowing seamless splicing of multiple units
  • lumen efficiency options: 120lm/W, 140lm/W
  • Adjustable CCT and wattage
  • Flicker-free operation with built-in driver
  • Functional variants: Emergency, sensor available
  • Dimming method: DALI /1-10V

Applications: Widely used for classrooms, workshops, warehouses, and exhibition halls.
