Six tricks for general lighting selection
1. It is safety: when choosing a lamp, you can't be greedy and cheap, but you must first check its quality, check the warranty book and the certificate is complete. Sometimes the most expensive is not necessarily the best, but it is not good to be too cheap. The quality of many cheap lamps is not enough, and there are always hidden dangers. Once a fire breaks out, the consequences are unimaginable.
2, look at the start-up performance: If the store has a best voltage regulator, in the power-off state, first turn the regulator at 150W (can be according to the minimum starting voltage indicator listed in the manual) output, install a cold light The hand leaves the light, and it is best to turn on the power once to ignite. It makes sense to describe such tediousness here.
3, look at the working state: the purchase of incandescent lamps to do the next step will be OK, energy-saving lamps are not the same, after the start is smooth, the regulator should be screwed to the head, output 250W voltage, work under high pressure for more than 5 minutes, let it heat up quickly, See if there is flicker, and if there is any odor overflow above the scent lamp.
4. Look at the interference situation: In China, electromagnetic compatibility is a project that must be passed by electrical appliances. However, the detection of this project is very complicated. When users buy lamps, they will see if they have passed the national electromagnetic compatibility test mark on the packaging. A medium-short-wave radio, when the lamp is working, put the radio nearby, the lower the noise emitted by the short-wave radio station, the better the electromagnetic compatibility of the lamp under test.
5, look at the performance after work: Finally, do not forget to compare the temperature of the lamp body after disassembly, the lower the temperature, the better, in addition, after the test, there will be a black mark on the root of the lamp, please be careful, this black section The longer and darker the lamp life is, the lower it will be.
6, the appearance of acceptance: the plastic shell of the lamp must choose the kind of engineering plastic flame retardant. Ordinary plastics are easily deformed and flammable, and are prohibited from being used in the production of energy-saving lamps. The two can be easily discriminated from the surface. The latter surface is smooth and shiny, and the surface of the former has a texture similar to frosted glass. In addition, from the perspective of the lamp, multiple lamps can be put together for comparison. The shape and size of the lamp are better. The machine is bent and formed. The consistency of the product is good, the quality is easy to be guaranteed, and the maintenance is Interchangeability is preferred. Of course, there should be no cracks, looseness, and traces between the interfaces.
