Neon sign components include neon tubes, tube supports, neon power supplies, and all secondary wiring from the neon supply. Fluorescent sign components include fluorescent tubes, ballast, and ballast secondary wiring, and in some cases lampholders.
Retrofit kits include the power supply or transformer, power supply or transformer enclosure, the LEDs and the LED mounting means, and installation instructions.
New sign construction
Component power units may be incomplete with respect to electrical enclosure, mounting, supply connections, etc. LEDs, secondary wiring, and LED transformers or supplies may be provided separately.
