What's Difference between T8 LED Tube and T5 LED Tube

T8 LED Tube, lamp behind the number 8 means that the perimeter of 8cm, diameter of 25.4mm (80/3.14).

Tube diameters of the following:

T12 diameter of 38.1 mm
T10 diameter of 31.8 mm
T8 diameter of 25.4 mm
T5 Diameter 16 mm
T4 diameter of 12.7 mm
T3.5 diameter of 11.1 mm
T2 diameter of 6.4 mm

LED lamps in most studies the heat problem to be solved, most people regard the thickness of T8 LED tube as 26.0. It is worth mentioning that the LED T8 Tube length. Because small diameter that can be a little coarse matter, both sides of the head as long as the PIN plug on it. Restrict the length of the tube, as is standard lighthouse, the general is 600mm and 1200mm two. But to say that although the lamp is to buy 600mm or 1200mm of, but actually 1.2 m long tube in the production of only 1190mm, while the lamp is usually 590mm 600mm

China now has nearly 80% of the fluorescent lights also are T8, supermarkets, hospitals, factories, lines, office market, the school almost all T8 LED tube lamp. With the development of technology in science and technology update, now the T5 fluorescent lamp can replace T8, and illumination, life and stability are to far beyond the T8 fluorescent lamp. T8 lamps replace the amount is significant.

Is now commonly used fluorescent T8, T5, T4 lamps, commonly used in the first two years include T10, T12. So, the "T" in the end what does that mean? T5 and T4 there any difference?
"T", is actually representative of a constant diameter tube. Each "T" is 1 / 8 inch.
We all know that one inch equals 25.4 mm. Then the T8 lamp diameter is 25.4mm.
The remaining figures correspond to the following:
T12 diameter of 38.1 mm
T10 diameter of 31.8 mm
T8 diameter of 25.4 mm
T5 Diameter 16 mm
T4 diameter of 12.7 mm
T3.5 diameter of 11.1 mm
T2 diameter of 6.4 mm
In theory, the more efficient the thin tube, that is the same wattage light more.

However, the finer the more difficult to start the lamp, so the development time to the T5 LED tube, electronic ballast must be used to start.
To save costs, T5, T4 are used in the form of a miniature stents sold is included in the ballast tiny space inside the stent.
Fluorescent size: T8, T5, T4 difference and tube length, shows the power
Fluorescent size: T8, T5, T4 difference and tube length, power note: specifications are commonly used fluorescent T8, T5, T4 lamp, companies use a set of three tubes is usually T5 lamp, long time ago Commonly used fluorescent specifications T10, T12.

"T", on behalf of "Tube", said tubular, T behind the numbers indicate the tube diameter. T8 is eight "T", a "T" is 1 / 8 inch.

One inch equals 25.4 mm. So every "T" is 25.4 ÷ 8 = 3.175mm

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

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

T8 tube diameter is (8 / 8) × 25.4 = 25.4mm [T8's just one-inch diameter tube] (Note: The uniform width 39mm, height 52mm)

Commonly used fluorescent length and power: (20w length 620mm; 30w length 926mm; 40w length 1230mm)

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

Commonly used fluorescent length and power: (8w length 310mm; 14w length 570mm; 21w length 870.5mm; 28w long 1170.5mm; 35w length 1475mm)

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

Commonly used fluorescent 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 lamp diameter is (3.5 / 8) × 25.4 = 11.1 mm

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