What is the category of LED bulbs, T6, T8 or whatever?
Each "T" is 1/8 of an inch. An inch is 25.4mm T12 is 38.1 mm in diameter T10 diameter 31.8 mm T8 diameter 25.4 mm T5 diameter 16 mm T4 diameter 12.7 mm T3.5 diameter 11.1 mm T2 diameter 6.4 mm The number behind T is the perimeter of the lamp. For example, T4 is 4 centimeters, and T5 is 5 centimeters. search That is, the number in the back of T is one eighth of the 25.4 millimeters (1 inch), which is the diameter. Originally, only the electric inductance ballast, "halogen powder" the fluorescent lamp.
I guess the owner is wrong T-tube, tube lamps, just ordinary daylight tubes, each T is 1/8 inch (inch) The T8 lamp is a lamp tube with a diameter of an inch T12 diameter 38.1 mm, T10 diameter 31.8 mm, T5 diameter 16 mm T4 diameter 12.7 mm T3.5 diameter 11.1 mm, T2 diameter 6.4 mm, etc LED lights include high power and low power, LED wall lamp, LED digital tube LED lighting, LED lighting, etc A little help to the landlord
In practical use, thin lamp tube is easy to conceal, use the occasion also be flexible, this is why T5, T4 light tube to get the reason that stylist people favour However, the more difficult the tube is, the more difficult it will be, so when it comes to the T5, the electronic ballast must be used to start the lamp. In order to save costs, T5, T4 of miniature stents has been adopted in the form of sale, mini space is the ballast in bracket, the efficiency and quality of the ballast are generally not very good, should lead to very high efficiency tubes as conventional T8 tubes instead of bright, life can be a little discount. Still, the lure of the tube is still strong, and the T5 and T4 bulbs are selling more and more. The difference between T5 and T4: The theory should be that T4 is efficient, but because of the quality of the ballast, many T4 is not as bright as T5. Life and stability are different, T4 is not as mature as T5, so life expectancy is slightly shorter than T5
