LED tube light specifications: the difference among T8, T5 and T4 LED tube light, tube length and power descriptions

"T" is the abbreviation for Tube. The number behind it represents the tube diameter. T8 means it has 8 Ts diameter. 1 T =1/8 inch.
1 inch=25.4mm, 1 T= 25.4÷8=3.175mm

T12 LED tube light diameter: (12/8)×25.4=38.1 mm

T10 LED tube light diameter: (10/8)×25.4=31.8 mm

T8 LED tube light diameter: (8/8)×25.4=25.4 mm
T8 LED tube light means that the tube's diameter is exactly 1 inch(PS: width 39mm, height 52mm)
Common LED tube light length and power:(20w length620mm, 30w length 926mm, 40w length 1230mm)

T5 LED tube light diameter: (5/8)×25.4=16 mm (PS: width 23.5mm, height 39mm)
Common LED tube light length and power:(8w length 310mm, 14w length 570mm, 21w length 870.5mm, 28w length 1170.5mm, 35w length 1475mm)

T4 LED tube light diameter: (4/8)×25.4=12.7 mm (PS: width 21mm, height 32mm)
Common LED tube light length and power:(8w length 341mm, 12w length 443mm, 16w length 487mm, 20w length 534mm, 22w length 734mm, 24w length 874mm, 26w length 1025mm, 28w length 1172mm)

T3.5 LED tube light diameter: (3.5/8)×25.4=11.1 mm

T2 LED tube light diameter: (2/8)×25.4=6.4 mm

LED tube lights are produced according to the specifications of common fluorescent lamps, so it could replace the latter to achieve energy-saving and environmental protection without replacing support bracket. Meanwhile it could save a lot of trouble and the money.

Theoretically, the thinner the LED tube light the more effective, and it means that it is much more brightness in the same amount of emergency.

Practically, the thinner the tube the easier to be concealed, and it is more flexible and applied to many occasions, that is why designers like using T4 and T5 LED tube light.

But, the thinner the tube the more difficult to start, when it developed to T5 LED tube light, the electronic ballast had to be used.

In order to saving the cost, electronic ballasts are usually in support bracket. But this directly causes low light effect and short serving time. Nonetheless, the selling of T5 and T4 is getting better and better. After all, it is hard to resist the attraction of thin tube.
