Direct/Indirect Led Linear Light 1040110U, 54W, 40x110mm, Suspended/Surface-mounted, Model No.: 1040110U, is a special linear lighting product delivering both direct and indirect lights in targeted areas, which gives a state-of-the-art solution for commercial & office sectors. It incorporates two PCB boards on two sides of the lights, delivering glare-free soft lights on two directions over a continuous run of line. The light length is flexible with different aluminium profiles, from 850mm to 3090mm per piece, which gives great flexibility & versatility in light planning.  (Note: Customized lengths need be made in factory prior to shipping.)

This direct/indirect Led linear light, adopting modular LED PCBA & high-quality built-in Led driver, maintains less than 10% light attenuation after 50,000 working hours.  It can be suspended to deliver lights on both upper and lower directions , or wall-mounted like a wall sconce washing the wall on both directions with prismatic lenses. Thanks to latest Led technology, it’s eco-friendly and energy-saving comparing with traditional incandescent lights or fluorescent lights.

Besides this direct/indirect light we still offer other sizes & kinds of Led Linear lights, please feel free to consult our sales if you have any specific demand.
