What is the power of energy-saving lamps? How to choose energy-saving lamps?

As a substitute for traditional lamps, energy-saving lamps occupy most of the market, but how much do you know about energy-saving lamps? What is the power of energy-saving lamps? Is there any skill in the method of purchasing energy-saving lamps? Let Bian Xiao teach you.

Types of energy-saving lamps:

From the shape of the lamp tube, energy-saving lamps are mainly divided into U-shaped tube, spiral tube, straight tube, lotus, plum blossom, bergamot and so on. Different energy-saving lamps have different power distribution.

Energy saving lamp power:

1, U-tube energy-saving lamps: tubular: 2U, 3U, 4U, 5U, 6U, 8U and other specifications, with power ranging from 3W to 240W. 2U, 3U energy-saving lamp, diameter 9mm- 14mm. General power is between 3W and 36W. Mainly used for civil and general commercial environment lighting. In the way of use, it is used to directly replace incandescent lamps. 4U, 5U, 6U, 8U energy-saving lamps, pipe diameter12mm-21mm. The power is generally from 45 W to 240 W. It is mainly used for lighting in industrial and commercial environments. In the way of use, it is used for direct substitution: high-pressure mercury lamp, high-pressure sodium lamp and T8 straight fluorescent lamp.

2. Spiral tube energy-saving lamp: spiral tube diameter.

The number of spiral rings (represented by t) is 2T, 2.5T, 3T, 3.5T, 4T, 4.5T and 5T, and the power varies from 3W to 240W.

3. Bracket energy-saving lamps: T4 and T5 straight tube energy-saving lamps: T5 and T4 straight tube energy-saving lamps. Power is divided into 8W, 14w, 2 1W, 28W. Widely used in civil, industrial and commercial environment lighting. It can be directly used to replace T8 straight fluorescent lamp.

Theoretically, the thinner the lamp, the higher the efficiency, that is, the more light emitted by the same wattage. However, the thinner the lamp, the more difficult it is to start, so when developing T5 lamp, electronic ballast must be used to start. In order to save cost, both T5 and T4 are sold in the form of mini-brackets, that is, the ballast is contained in the micro-space of the bracket. The efficiency and quality of this kind of ballast are generally not good, which leads to the high-efficiency lamp is not as bright as the traditional T8 lamp, and its service life is somewhat discounted. Nevertheless, the temptation of thin tubes is still great, and the sales of T5 and T4 tubes are also increasing.

How to choose energy-saving lamps;

1, depending on the packaging brand

For example, choose products with safety certification such as the Great Wall logo; Choose one with high brand awareness; Choose the one with exquisite packaging, exquisite appearance, complete address and telephone number of the manufacturer and complete technical description.

2. Look at the performance

If there is a voltage regulator in the store, it's best to turn on the voltage regulator with 150W output when the power is off, install the electro luminescent, and keep your hands away from the lamp. It's best to turn on the power and light it at one time. The starting of energy-saving lamps has two characteristics, one is that the higher the temperature, the easier it is to start, and the other is that the lamp is easier to start under the induction of human contact. Also remind you of the problem of "one ignition". Many lights come on as soon as they are turned on, which is not good. Elegant lamps often have filament preheating circuit when starting, and there will be a delay of about 0.4 seconds when starting, so "one-time ignition" should be understood as the minimum flicker when starting, and red light should not appear at the root of the lamp tube.

3, look at the working state

It is enough to buy incandescent lamps instead of energy-saving lamps. After successful start-up, turn the voltage regulator to the end, output 250W voltage, and work at high voltage for more than 5 minutes, so that it can quickly heat up to see if there is flicker, and at the same time, whether there is odor overflowing above the sniffing lamp.

There are energy-saving lamps at home at any time, but the power of energy-saving lamps should also be suitable for the home environment, making people feel comfortable. I hope everyone knows more about energy-saving lamps and chooses the ones they are satisfied with.
