Product Release

A new style of 4" LED downlight with frosted lens and lower trim is available now in the market. The unique edge of the new LED downlight to other types of LED downlight is that it adopts frosted lens which can bring more uniform and consistent light distribution instead of clear lens which is widely used by the previous generation. Thanks to the frosted lens with unrivaled CRI up to 92, the 4" LED downlight can bring you beautiful lighting quality that you would expect from a CFL, while the power consumption is just a half as a CFL's. With Nichia LEDs as light source, the LED downlight features a high lumen efficacy of over 60 lumen per watt. The new LED downlight which can be dimmable to 10% and compatible with most conventional dimmers is an optimum replacement for incandescent downlights and CFLs. The lower trim enables better reflecting effect and prevents dust and insects from entering the lamp body. With spring torsions, this 4" LED downlight can be easily installed into most 4" recessed can housings. The 4" LED downlight is developed by Fobsun Electronics Ltd, a leading global LED lighting manufacturer and supplier. Fobsun has announced the commercial availability of the new FCL4 4" LED downlights in July, 2011.


FCL4 led downlights

The FCL4 recessed downlight utilizes aircraft grade aluminum alloy as body material and top grade frosted optics lens, which ensure not only low running temperature, but also optimum light transmittance and distribution. This new style LED downlight employs overload protection which greatly improves safety and reliability, FOBSUN's unique temperature control system built in this recessed light can prevent the inside components from overheating, and the built-in heat sensor can monitor temperature of the components, which significantly prolongs the real working lifetime of the lamp fixture.

The FCL4 family is suitable for architectural lighting applications. The LED recessed light provides higher efficacy and longer life than Compact Fluorescent Lamps with the beautiful light quality that you would expect from an incandescent. Suitable for installation in standard-height rough-in sections, fits into most popular 4" recessed can housings. Also available with a dedicated rough-in section for new construction. Also we can provide black housings and black sand blasting trims for special application, such as cinema, theater etc...
