The commonly used LED fluorescent lamp specifications include T8, T5 and T4 tubes. A group of three tubes used by enterprises is usually T5 tubes. Long ago, the commonly used LED fluorescent lamp specifications were T10 and T12.

The commonly used LED fluorescent lamp specifications include T8, T5 and T4 tubes. A group of three tubes used by enterprises is usually T5 tubes. Long ago, the commonly used LED fluorescent lamp specifications were T10 and T12.

“T” stands for “tube”, which means tubular, and the number after T represents the lamp diameter. T8 means there are 8 “t”, and a “t” is 1 / 8 inch.

One inch equals 25.4 mm. Then each “t” is 25.4 ÷ 8 = 3.175mm;

The diameter of T12 lamp tube is (12 / 8) × 25.4＝38.1 mm

T10 tube diameter is (10 / 8) × 25.4＝31.8mm

T8 tube diameter is (8 / 8) × 25.4 = 25.4mm [T8 is just one inch in diameter] (Note: uniform width 39mm, height 52mm)–carrying tape

Length and power of common fluorescent lamps: (20W 620mm long; 30W 926mm long; 40W 1230mm long)

The diameter of T5 lamp tube is (5 / 8) × 25.4 ＝ 16 mm (Note: uniform width 23.5mm, height 39mm)

Length and power of common fluorescent lamps: (8W 310mm long; 14W 570mm long; 21W 870.5mm long; 28W 1170.5mm long; 35W 1475mm long)

T4 tube diameter is (4 / 8) × 25.4 ＝ 12.7 mm (Note: unified width 21mm, height 32mm)

Length and power of common fluorescent lamps: (8W 341mm long; 12W 443mm long; 16W 487mm long; 20W 534mm long;

22W, 734mm long; 24W, 874mm long; 26W, 1025mm long; 28w (1172mm long)

T3. 5 the diameter of the lamp tube is (3.5 / 8) × 25.4＝11.1 mm

The diameter of T2 tube is (2 / 8) × 25.4＝6.4 mm

LED fluorescent tubes are manufactured according to the specifications of ordinary fluorescent lamps. Their specifications are as large as the same. LED fluorescent lamps can be easily replaced with ordinary fluorescent lamps without replacing the support, so as to achieve environmental protection and energy saving, which is conducive to saving the replacement cost.–carrying tape
