Detailed explanation of technical parameters and standards for lighting fixtures

1、 Electrical parameters

1. Rated voltage

The rated voltage of lamps is generally 220V, and there are also some special lamps with a rated voltage of 110V or 24V.

2. Rated power

The rated power of a lamp refers to the power consumed by the lamp during operation, generally measured in watts (W). The rated power of different types of lamps also varies.

3. Power factor

Power factor refers to the phase difference between the input current and input voltage of a lighting fixture, which is an dimensionless value generally between 0.5-0.95.

2、 Optical parameters

1. Luminous flux

Luminous flux refers to the total amount of light emitted by a lamp, usually measured in lumens (lm). The higher the luminous flux, the brighter the light emitted by the lamp.

2. Color temperature

Color temperature refers to the color of the light emitted by a lamp, usually measured in Kelvin (K). The higher the color temperature, the whiter the light emitted by the lamp, and vice versa, the yellower.

3. Color reproduction index

The color reproduction index refers to the degree to which the light emitted by a lamp reproduces the color of an object, usually measured in Ra. The higher the Ra, the better the restoration of the color of the object by the light emitted by the lamp.

3、 Safety standards

1. Waterproof grade

The waterproof rating refers to the waterproof performance of the lighting fixture, generally expressed as IP (Ingress Protection) rating. The higher the IP level, the better the waterproof performance of the lighting fixtures.

2. Lightning protection level

The lightning protection level refers to the lightning protection capability of the lighting fixture, generally expressed as a level. The higher the level, the stronger the lightning protection capability of the lighting fixtures.

3. Electromagnetic compatibility

Electromagnetic compatibility refers to the electromagnetic radiation and sensitivity performance of lighting fixtures, generally expressed in grades. The higher the level, the better the electromagnetic compatibility of the lighting fixtures.
