GE DI4 4" Series
If you've been looking for a more energy efficient lighting system for your retail space, then look no further than the DI4S and DI4R LED downlights from GE Lighting. Part of the DI Series, both of these products offer improved color rendering, energy savings, and long lamp life, all in a more environmentally-conscious option.
The DI4R features a 4 inch round aperture, while the DI4S has a 4 inch square aperture. Made to be used in new construction applications, both fixtures are made of rugged 16-gauge galvanized steel with a junction box of the same material with multiple knockouts for easy installation. Both come with universal mounting brackets with over 3 inches of vertical adjustment, allowing them to be installed on a variety of different hanger bars.
A unique feature of both these products is the use of an Infusion™ LED technology downlight module in each fixture, which allows the modules to be twisted in and out as necessary without the use of tools, making for easy upgrading and replacements. The DI4R and DI4S are both rated to illuminate for up to 50,000 hours. The DI4R provides lumens of up to 1,730 in four different color temperatures -- 2700K, 3000K, 3500K, and 4000K -- and a 90 CRI. The DI4S illuminates with 1,930 lumens at its highest point with the same color temperatures and CRI. Both can be used with 0-10V dimming down to 10%, and both come with a five year limited warranty.
