1.At present, the material of the LED fluorescent tube kit mainly includes aluminum-plastic tube housing, glass tube housing and plastic tube housing. At present, the common LED lamp tube materials on the market are mostly aluminum-plastic, but the aluminum-plastic materials are not safe, and the PC material department is easily aged, deformed and has a short life. Aluminum-plastic pipe cooling machine is better. However, due to the composition of aluminum, conductive leakage occurs easily, causing an accident. The strength of the all-plastic pipe is that it has good heat conduction and can be physically insulated, but the heat dissipation effect is not good, and it is easily bent and deformed at high temperature.

2, led tube according to the diameter of the tube is divided into T12, T10, T8, T6, T5, T4, T3, etc., currently with T8, T6, T5 as the mainstream. In particular, due to the technical characteristics of T5 fluorescent tubes, advanced technical performance, high luminous efficiency, outstanding lighting quality and outstanding effects, T8 fluorescent tubes are being replaced at a faster speed.

3. In theory, the thinner the LED tube is, the higher the efficiency is, that is, the more wattage is emitted. In order to save costs, T5 and T4 are sold in the form of micro-brackets, which are contained in the micro-space of the bracket. The efficiency and quality of such ballasts are generally not good, resulting in lamps that should be highly efficient. Contrary to the conventional T8 tube, the life is also a bit discounted.

Led tube length and power

1. The “T” of the led tube represents “Tube“, indicating that the object is tubular, and the number behind T indicates the diameter of the tube. Each “T” is 1/8 inch and one inch is equal to 25.4 mm. Then each “T” is 25.4 ÷ 8 = 3.175 mm, then the diameter of the T8 tube is 25.4 mm.

2, the length of the T8 tube (Note: uniform width 39mm, height 52mm). 20w length 620mm; 30w length 926mm; 40w length 1230mm; length of T5 tube (Note: uniform width 23.5mm, height 39mm). 8w length 310mm; 14w length 570mm; 21w length 870.5mm; 28w length 1170.5mm; 35w length 1475mm.

3, the length of the T4 tube (Note: uniform width 21mm, height 32mm). 8w length 341mm; 12w length 443mm; 16w length 487mm; 20w length 534mm; 22w length 734mm; 24w length 874mm; 26w length 1025mm; 28w length 1172mm. The diameter of the T12 tube is (12/8) × 25.4 = 38.1 mm; the diameter of the T10 tube is (10/8) × 25.4 = 31.8 mm.

Led lamps, whether in production specifications or in the market sales classification, there are many types, so if you want to buy led lamps in your home, you must determine the actual needs of the home, compare the LED tube Well, at the same time, we should learn more about the length and power of LED tubes and other related knowledge to improve the rationality of everyone’s purchase.

In the lighting requirements of the family, brightness is the first requirement. At the same time, energy saving is required. There are many lighting products on the market. The LED tube is a widely used product. If you want to buy a LED tube, then You should have an understanding of the LED lamp brand. Let’s take a look at which LED lamp is good, and also understand the size and size of the LED lamp.
