The Pencil™ Programmable Dimming LED Driver

Measuring in at just 0.75 inches wide and 0.75 inches high The Pencil Programmable LED Driver is truly LED innovation. It has the shortest height and narrowest form factor on the market. Designed small for architectural lighting applications, this versatile driver is programmable, with Deep-Dimming and 3X wider voltage range than the competition.

Key Features of the 30 W, 25 W
and 13W models include:

  • 0.75 inches wide x 0.75 inches high

  • Up to 3X wider voltage range on 30 W models

  • The industry’s most popular dimming option: 0-10 V

  • Deep Dimming technology (100% down to 0.5% to off)

  • UL Class P

  • Costs up to 15% less than the competition

  • Designed small for architectural lighting applications
