What’s the T12 Lamp Holders?

All fluorescent light fixtures consist of at least lamp(s), T12 Lamp Holders, fluorescent ballast and internal wiring. Some older types have “starters”, too. The ballast is used to create the voltage and current necessary to start and illuminate the fluorescent lamp. In time, the ballast may need to be replaced. Read on to learn how to swap out the old with an approved replacement ballast of the same technology. Please read the entire article and warnings before attempting.

The linear fluorescent T12 Lamp Holders continues to grow with the newly introduced T8 series featuring rotary lamp-lock technology and bottom push-in wiring. Our linear fluorescent brochure details the many different mounting, wire insertion and lamp insertion configurations available.

For easy installation, reducing costs and safety reasons, many straight tubular fluorescent ballasts are installed in the bracket, constitute self-ballasted fluorescent lamps.
According to the size of the diameter.

T12 fluorescent lamp holders types
(A), straight-tube fluorescent tube divided by the diameter size: T12, T10, T8, T6, T5, T4, T3, and other specifications. Specifications “T + number” portfolio, which means that the value mm diameter. Its meaning: a T = 1/8 inches, one inch is 25.4mm; figures represent the number of T’s. If T12 = 25.4mm * 1/8 * 12 = 38mm.

(B), fluorescent tube diameter and its electrical parameters of the relationship:
fluorescent tubes, the finer diameter, the higher the voltage ignition starter, ballast technology for higher performance requirements.
Diameter greater than T12 fluorescent tubes, low voltage ignition starter. Relative to 220V, 50Hz frequency alternating current, in line starter ignition voltage is less than 1/2 the supply voltage laws.
