Three-proof lamp refers to waterproof, dust-proof and anti-corrosion. Explosion-proof lamp means no sparks. Some explosion-proof lamps include three-proof lights, while three-proof lights do not include explosion-proof.

Three-proof lamps and explosion-proof lamps are only the difference between the shell, and you can choose a variety of light sources. The choice of light source mainly depends on the purpose:

1. Street lamps generally have metal halide lamps and high-pressure sodium lamps, which have the disadvantages of slow start-up, energy-saving advantages, high power, and strong ability to penetrate haze, especially high-pressure sodium lamps and other good fog penetration performance.

2. For high-frequency switching lamps, both incandescent lamps and LED energy-saving lamps can be selected. The price of LED energy-saving lamps is the highest, followed by incandescent lamps.

3. Metal halide lamps and high-pressure sodium lamps are the most cost-effective for high-power fields, which can achieve 1000W.

4. Energy-saving lamps for general office occasions, LED can be selected if economical permits. For high-rise buildings and chimneys, choose special high-altitude obstruction lights.

5. When people are likely to encounter lamps and other dangerous situations, in view of the use of 24V and 36V lamps, the LED effect is best. For example, the LED explosion-proof sight hole lamp used in the reactor is 36V.

6. Energy-saving lamps cannot be used in indoor basketball halls and table tennis halls where stroboscopic requirements are required.

7. For shopping malls and other occasions that have requirements for color rendering index, colored lamps and other lamps that affect color rendering cannot be selected (except for special color rendering requirements such as advertising effects, etc.).
