Fobsun Electronics Limited unveils their new 4-inch recessed downlights recently. As one of the biggest Chinese LED Lighting Manufacturers, Suppliers and Exporters, FOBSUN always insists on supplying LED Lighting products with best design and quality at the lowest price to the market, now let us have a look at the unique edges of the new recessed downlights.

FOBSUN’s new 4-inch recessed downlights are an amazing combination of technical innovations, including breakthroughs in optical design, electronics design, mechanical design, and thermal management. The LED recessed downlights have the highest CRI ever, which is higher than 90 for warm white and higher than 80 for natural white. They employ overload protection which greatly improves safety and reliability. FOBSUN's unique temperature control system built in them can prevent the inside components from overheating, and the built-in heat sensor can monitor temperature of the components. They also employ FOBSUN's latest top dissipation process technology which can control LED junction temperature around 90-95 degree Celsius, thus significantly reduces the heat generation of LEDs and greatly improves the reliability and real lifetime of the lamps. They feature more uniform and comfortable light distribution due to the advanced light transmittance material and design.

The recessed downlights utilize aircraft grade aluminum alloy as body material and top grade light guide plate. They can be compatible with most existing recessed can housings, and the recessed downlights are suitable for architectural lighting applications. They can provide higher efficacy and longer life than Compact Fluorescent Lamps with the beautiful light quality that you would expect from an incandescent.
