Product Release

Fobsun Electronics Limited, a leading global LED lighting products manufacturer and supplier, has released their new style square LED downlights which are available in 4 inch, 6 inch and 8 inch recently.



4", 6", 8" square recessed LED downlights are newly developed by Fobsun to replace conventional square lighting fixtures. The square shaped super pure polished aluminum housing with high brightness Nichia or Epistar LED chips and quality PMMA lens to ensure high lumen output, uniform light distribution and low heat generation. The high reliable external constant current driver guarantees not only high energy efficiency but also long life span of the LED downlights.

The square downlights are TRIAC dimmable to 8% and compatible with most common dimmers. The new square LED downlights come with wide input voltage range: AC100-240V 50/60Hz, which ensures them to be widely uised in different countries and regions. Due to the high efficacy of LEDs, the LED downlights are ultra energy efficient and can save over 50% electricity bill compared to the conventional CFLs. The square LED downlights are 100% environment friendly and do not contain any hazardous materials such as mercury, lead and so on.

The LED downlights are designed with an extremely long lifespan of over 35,000 hours, which is nearly 7 times as the lifetime of CFLs. The square recessed LED downlights are easy to install and maintain, and thanks to the durability of solid state lighting, they hardly need any maintenance costs during their lifetime. Our LED downlights are direct replacements for traditional CFLs, they are suitable for cabinet, restaurant, houses, villa, hotel etc.
