The Armacost Lighting PureVue Dimmable LED Puck Lights are the perfect solution for taking your under cabinet LED lighting to the next level. The all metal design measures only 5/8-in thick, making the puck lights an ideal solution for surface mount fixtures or as a recessed flush mounted, ultra-thin downlight. The PureVue LEDs are extremely energy efficient, consuming only 4 watts per LED puck light. The lights produce about 375 lumens of light or roughly that of a 40W incandescent bulb. Thanks to its PureVue diffusion technology, visible LEDs and spotted countertop reflections are eliminated. With no bulbs to change and maintenance-free operation, expect reliable use for years to come.
