Recessed lighting fixtures such as LED panel lights
and LED troffers
are designed to be recessed into a dropped ceiling, ceiling grid and tile system, or other engineered ceiling system. The design of architectural surfaces increasingly demand energy efficient light fixtures with aesthetically pleasing designs to provide quality ambient lighting. Troffer-style fixtures, e.g. parabolic troffers, volumetric troffers and prismatic troffers are ubiquitous in commercial buildings, offices, institutional facilities and industrial spaces throughout the world. Preference for recessed troffers has shifted from relatively inefficient, maintenance-heavy fluorescent troffers toward low profile, energy efficient LED lighting systems. LED troffers offers exceptional performance, superior energy savings, improved visual appearance and require minimal maintenance over their long operational life. These type of light fixtures works well in lighting renovation or retrofit projects where new technology is desired and budget-consciousness is needed. Recessed LED troffers, however, are relatively deep and cumbersome fixtures. With an exceptionally thin and light weight structure, edge-lit LED panel lights significantly elevated the aesthetics and functionality of recessed lighting fixtures. Its waveguide optical architecture enables uniformly distributed light across the panel without hot spots, flicker or glare. The streamlined look enhances a sense of space and seamlessly complements a variety of commercial and residential settings.
