Selection method of orchid faucet red crown energy-saving lamp

See if there is a national inspection report; Look at the outer packaging of the product, including the trademark, nominal power and labeling content of the product, and wipe it with a soft wet cloth. If the mark is clearly identifiable, it is the qualified service life. Qualified energy-saving lamps can be used for more than 500 hours in the experimental state, and must last for more than 200 hours in normal use. If you can't meet this standard, it is a poor quality product. Safety requirements: during installation and disassembly, check whether the lamp cap is loose, bent and insulated; See whether the outer tube material of the energy-saving lamp is heat-resistant and fire-proof, and whether the fluorescent powder in the lamp is uniform.

If it is not used, the two ends of the lamp tube will turn black, which is an unqualified product; Another point is the price comparison. Generally speaking, due to special reasons, the cost of energy-saving lamps is relatively high.

If it is an energy-saving lamp with seven or eight yuan, it is likely to be inferior products produced by some small factories. Generally, the price of domestic energy-saving lamps is more than 40 to 50 yuan, and the imported ones are higher.
