Led Fluorescent Tube Appearance Parameters
Writer：Jane Time：2021-07-28 Browse：191 Green lighting has entered the homes of ordinary people, but for ordinary consumers, this thing is really not understand, say the price, dozens of pieces to three or four hundred; Warranty, there is a year, two years, four or five years also; What about performance? I don't know what to ask. So how to find a beautiful, energy-saving, and durable LED fluorescent lamp? Below we come to bask in, from the appearance first say.
1. From the diameter of the LED tube:
Mainly T5, T8, T10 and, rarely, T12:
The number on the "T" side refers to the diameter of the LED Tube. It is in English units. One "T" is an eighth of an inch.
One inch is 25.4 millimeters. So each "T" is 25.4÷8 = 3.175mm
The diameter of T12 tube is (12/8)×25.4 = 38.1mm
The diameter of T10 tube is (10/8)×25.4 = 31.8mm
The diameter of a T8 tube is (8/8) x 25.4 = 25.4mm.
The tube diameter of T5 is (5/8) *25.4=15.9mm
In traditional fluorescent lamp T8 tube is the biggest mainstream now, the fluorescent lamp of T5 basically is given priority to with three primary color fluorescent lamp, T10 fluorescent lamp basically has been very few in the market.
Because in the early stage of LED fluorescent tube development, many constant current power supply can not be miniaturized, so it can not be built in T8-LED light lamp LED constant current power supply, so there is T10 fluorescent lamp on the market, and some solar tube factory even can not do T10, so there is T12. However, the T10 and T12 interface can not be used on the G13 lamp holder of the T8 lamp holder, so the lamp holder of T12 and T10 above is in two sections. That's T10 to T8.
Therefore, from the diameter of LED fluorescent lamp, it is best to find the ability to develop the true T8 (within 26MM diameter) factory. Because T8 LED daylight tube has now been developed for more than two years, to now or in the same place marking time manufacturers, its enterprising spirit can be imagined.
2. From the length of the traditional lamp:
T8 fluorescent lamp length and power:
Traditional 20W fluorescent lamp length 620mm, conventional is 2 feet, or 60cm, this length of LED fluorescent tube power is generally 7~10W;
Traditional 30W fluorescent lamp length 926mm, conventional is 3 feet, or 90cm, this length of LED fluorescent tube power is generally 11~14W;
Traditional 40W fluorescent lamp length 1230mm, conventional is 4 feet, or 120cm, this length of LED fluorescent tube power is generally 15~20W;
T5 fluorescent lamp length and power:
8 w 310 mm long; 14 w 570 mm long; Conventional is 2 feet, or 60cm, this length of LED fluorescent tube power is generally 5~10W;
21 w 870.5 mm long; The general saying is 3 feet, or 90cm, this length of LED fluorescent tube power is generally 8~14W;
28 w 1170.5 mm long; Conventional is 4 feet, or 120cm, this length of LED daylight tube power is generally 13~18W;
35W long 1475mm) is generally said to be 5 feet, or 150cm, this length of LED daylight tube power is generally 18~22W;
In the purchase of LED daylight tube, as far as possible to choose and the market on the general length, so as not to cause installation inconvenience, and the kit must be independent mold problems, so as to increase the cost of the product.
It is best not to find some unreasonable power, for example: find 60cm long, 20W. Such LED tubes in addition to some unscrupulous manufacturers dare to do, regular LED solar tube manufacturers will not do so, because an LED lamp is not only said to be able to make the problem, but also must be produced after the heat dissipation, light decline, failure rate and other factors.
