Principal Lighting Group is Granted Additional LED Retrofit Patent

It’s Principal LED’s fifth LED-to-fluorescent replacement patent.

Principal LED (P-LED) has been granted U.S. Patent No. 10,400,960, which relates to our market-leading Stik™ family of direct-connect LED retrofit assemblies.

“This latest patent further expands our intellectual property portfolio and will add features to continue to simplify the fluorescent-to-LED retrofit conversion process,” partner at P-LED, J. Bryan Vincent said.

Patent 10,400,960 covers the use of a fluorescent to LED retrofit that is powered through the existing sockets, removing the need for rewiring the interior of difficult to access signs. This is Principal LED’s fifth LED to fluorescent replacement patent, alongside U.S. Patent No. 10,024,501, U.S. Patent No. 9,851,054, U.S. Patent No. 9,311,835, and Canadian Patent No. 2,759,366.

“We anticipate existing Stik products with a “wireless” option to be commercially available in the coming months,” Vincent said. “In addition to inventing products that improve the retrofit process, we continue to assemble our products in the U.S. to ensure quality and provide just-in-time customization for our clients.”

P-LED’s patented product lineup includes:

• Tap Out™ Stik
• Qwik Stik™
• Street Stik™
• Pinnacle Stik™
