Double-capped fluorescent lamp

Introduction:

The double-capped fluorescent lamp, also known as the straight tube fluorescent lamp, is a traditional lighting source that uses ultraviolet light generated by low-pressure mercury vapor to excite the phosphor coating to emit light.

classification:

According to the power can be divided into: 40W, 36W, 20W, 15W, 8W. According to the size of the fluorescent tube diameter, it can be divided into: T12—38mm in diameter, T10—32mm in diameter, T9—29mm in diameter, T8—26mm in diameter, and T5—16mm in diameter.

How to buy:

When buying tubes, you should first determine the specifications you need: straight tube fluorescent lamps have many specifications, and tubes of the same power have different tube diameters and luminous colors. The choice of tube thickness mainly depends on whether it is coordinated and beautiful with the appearance of the lamp used. The choice of the luminous color of the lamp is mainly based on personal preference. For example, if you like the light color "cold", you can buy the lamp with the letters RR, RZ, RL, and RB; if you like the light color "warm", you can buy the lamp. The luminous color of the lamp tube marked with the letters RN and RD is light yellow, which is relatively soft. When choosing a lamp, the first thing to look at is the label, the label on the package or the manual, and a few more questions about the information you don’t know, you may find many problems, and provide some information to help you purchase. Beware of buying products that have forged the place of origin, fraudulently used other people's factory names, or fraudulently used certification marks. Some old brands have won the trust of consumers, leading some unscrupulous manufacturers to forge their origins and use others' brands, especially the "three noes" products, which are absolutely impossible to buy. The second look at the appearance, such as whether the lamp pin is loose, whether the fluorescent powder coating of the lamp tube is uniform, and there is no leakage. Third, you can turn on the lamp to see if the lamp emits normally and evenly, and the lamp should have no dark spots.

Pay attention to when using the lamp: 　

1. In order to prolong the service life of the lamp, frequent switching should be avoided.　

2. If both ends of the lamp tube are severely blackened, in order not to affect the lighting effect, the lamp tube should be replaced in time.　

3. The power supply should be disconnected when replacing the lamp tube.　

4. The lamp contains a toxic substance mercury, so it is necessary to avoid damage to the lamp as much as possible.
