TPI's Clamp LED Portable Utility Light CPLED1 provides the longest lamp life while the lowest energy usage per lumens are produced. Each light head is designed with an acrylic lens cover over each of the 12 watt LED emitters and a narrow 15 degree angle beam generates 960 lumens per bulb. The clamp on mount secures the light head to most surfaces up to 3". A 9-3/8" long 7-3/4" diameter aluminum shade swivels 300 degrees horizontally and 210 degrees vertically while remaining cool to the touch. The CPLED1 is ETL C/US listed for indoor applications only. A bulb, an on / off switch and wire guard are included with each light head.
