Where is the difference between T8, T5 and T10? Let me tell you

In theory, the T8 is brighter than the T5, and the brightness is higher when the diameter is larger. At present, nearly 80% of the fluorescent lamps in China are still T8. The supermarkets, hospitals, factories, assembly lines, office buildings and schools are almost all T8 lights. With the development of technology, the technology is now updated. Now the T5 lamp can replace the T8 fluorescent lamp. The illumination, life and stability are far beyond the T8 fluorescent lamp. The most important thing is energy conservation. The ratio of 28 to 36+9 is obvious. Enterprises benefit and the country saves energy.

The model below T4 cannot replace the brightness of T8, and it is not commercially available for the time being, and it cannot be widely used.

T5 is a new type of lamp T8 is old-fashioned

The main difference is that the appearance of T5 is small and thin T8 is thick and long.

The intrinsic is that T5 saves energy between 50% and ~40% than T8.

And life is nearly 1 times longer than T8

Straight tubular fluorescent tube φ16mm (5/8 inch), φ26mm (1 inch), φ32mm (1 1/4 inch), φ38mm (1 1/2 inch)

Equivalent to T5, T8, T10 and T12 respectively

The T5 fluorescent lamp has good color rendering performance. Because it uses a rare earth trichromatic phosphor composed of three primary colors of red, green and blue, the color rendering index Ra can reach 80 or more.

And T5 fluorescent lighting is high. The luminous efficiency of the T5 fluorescent lamp with a correlated color temperature of 2700K is about 100LM/W.

The ordinary T8 fluorescent lamp has a luminous efficiency of about 70 LM/W, and the ordinary T12 fluorescent lamp has a luminous efficiency of about 60 LM/W.

T12----tube diameter 38mm

T10----tube diameter 32mm

T8----pipe diameter 26mm

T5----pipe diameter 16mm

T4----pipe diameter 12mm

T3----tube diameter 9mm

T2----tube diameter 7mm

From below T5, special electronic ballasts should be used, and ordinary magnetic ballasts are difficult to start.
