Energy saving lamp is also called compact fluorescent lamp. In addition to white (cold) light, there is still yellow (warm) light. In general, in the same watt situation, an energy saving lamp can save 80 percent energy of incandescent lamp and only 20 percent thermal radiation. In normal condition, a 5 watts energy saving lamp is equivalent to 25 watts incandescent lamp and 7 watts is equivalent to 40 watts.
It is first invented by foreign manufacturers in 1978. Because of high efficiency (5 times than ordinary light bulb), significant energy saving, long life (8 times than ordinary light bulb), small size and easy to apply, it is popular with people and countries. Now, many families have already used the lamp. So, how do consumers distinguish the quality of it? Following below:
1. Select the products with safety certificate, whose quality can be guaranteed.
2. The packing should be fine and beautifully printed. Name, address, telephone number, complete instructions and other information are complete. Check the appearance of light and its plastic part should be marked clearly the source (it may be a trademark or name of manufacturer), rated voltage and voltage range, rated power and rated frequency;bulbs should be smooth, no bubbles;phosphor coating inside the lamp should be fine, no granule and uniformly white;lamps and plastic parts should be securely connected, not loose;no sound when hand shaking the whole lamp.
3. The plastic case must be made from specific engineering plastic and ordinary plastic is banned for production. In addition, compare lights and choose with good consistency in shape and size. Meanwhile, The shell can not be cracked and loose.
4.Booster available is the best when purchase. Regulate the booster to 150V (or the minimum voltage marked on the instruction) and equip with an energy saving lamp,then it should be able to pass once when power is on. Because energy saving lamp starts with two characteristics:First, the higher the temperature is, the easier to start;Second, it is easily started under the effect of human body. It is worth mentioning that there should be about 0.4 second start delayed time after setting up the filament preheating circuit inside a lamp.
5. Electromagnetic compatibility is the necessary performance of household appliances. When you buy, examine whether it is through the test.
6. The temperature of energy saving light rises slowly in normal state, otherwise, its life will be short. Meanwhile, both ends are black or filament is red or flashing when the lamp is on shows it has quality problems.
7. Purchasing the energy saving lamp, you can only consider the price, regardless of quality. If blind pursuing low price, it is very likely to buy substandard products.
