Fluorescent tube lamps are double-ended fluorescent lamps. Common nominal power has 4W, 6W, fluorescent
Fluorescent 8W, 12W, 15W, 20W, 30W, 36W, 40W, 65W, 80W, 85W and 125W. Diameter with T5, T8, T10, T12. fluorescent Lampholder G5, G13.
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
(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.
(Two), fluorescent tube diameter and its electrical parameters of the relationship:
1, fluorescent tubes, the finer diameter, the higher luminous efficiency, energy-saving, the better.
2, fluorescent tubes, the finer diameter, the higher the voltage ignition starter, ballast technology for higher performance requirements.
Diameter greater than T8 (including T8) 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. You can employ inductive ballast, starter ignition operation performed.
Diameter less than T8 fluorescent tubes, high voltage ignition starter. Relative to 220V, 50Hz frequency alternating current, does not meet the starter ignition voltage is less than 1/2 of the law of supply voltage.starter ignition operation performed. Diameter less than T8 fluorescent tubes, electronic ballasts must match. By the electronic ballast, starter generate high pressure, the fluorescent tubes breakdown ignited.
