PRODUCT OVERVIEW

9881-3: GASKET.

Verbatim’s Dichroic MR16 GU5.3 LED Lamp is a high-quality, energy efficient replacement for halogen dichroic lamps. Known for their unique glitter/surround appearance, dichroic lamps allow light to pass through the dichroic coating, which creates a unique lighting effect at the back of the lamp, similar to halogen MR16’s, and reduces heating of illuminated objects. Because they lack the traditional LED heat sink, Verbatim Dichroic MR16 LED Lamps are ideal for track and pendant lighting applications in museum, hospitality and retail spaces.

Backed by Verbatim’s 3-year limited warranty, the 3000K Dichroic MR16 lamp has an estimated design lifetime of 25,000 hours, resulting in reduced maintenance and replacement costs when compared to halogen lamps. This part is cataloged in the U.S. Government catalog under NSN 5330-00-334-9371, indicating validated use in U.S.

government and defense logistics supply chains.
