UL 879A:2016 PDF Download

The UL 879A:2016 standard covers LED kits that are designed for two specific purposes: retrofitting existing signs in the field and installation in new signs.

For retrofit kits, the standard addresses the replacement of electrical components used in different types of sign illuminations, such as neon, fluorescent, and HID. This includes components like neon tubes, power supplies, ballasts, and secondary wiring. The retrofit kits are required to include the necessary power supply or transformer, enclosure, LEDS, LED mounting means, and installation instructions.

Regarding new sign construction, the standard allows for component power units to be incomplete, meaning that they may not include all electrical enclosures, mounting equipment, or supply connections. Additionally, the standard permits the provision of LEDs, secondary wiring, and LED transformers or supplies separately for new sign installations.
