1. Brightness

The brightness of LED lamp beads is different and the price is different.

Lantern cup: Generally brightness is 60-70lm; Bubble Lights: Generally brightness is 80-90lm.

1W red light, brightness is generally 30-40lm; 1W green light, brightness is generally 60-80lm; 1W yellow light, brightness is generally 30-50lm; 1W blue light, brightness is generally 20-30lm.

Note: 1W brightness is 60-110LM; 3W brightness can reach up to 240lm; 5W-300W is an integrated chip, which is packed in string/parallel.

LED lens: A lens is generally used in PMMA, PC, optical glass, silicone (soft silicone, hard silicone) and other materials. The larger the angle, the higher the light efficiency. With a small angle LED lens, the light must be shot far.

2. Wavele

The wavelength is consistent and the color is consistent. The price is high.

White light is divided into warm color (color temperature 2700-4000K), white (color temperature 5500-6000K), cold white (more than 7000K) Europeans prefer warm white.

Hongguang: The band is 600-680, of which 620, 630 are mainly used for stage lights, and 690 is close to infrared.

Blu-ray: Band 430-480, of which 460,465 stage lights are used more.

Green Light: The band is 500-580, of which 525, 530 stage lights are used more.

3. Lighting angle

The LEDs with different uses are different. The special lighting angle, the price is high.

4. Anti -static ability

LED lamp beads with strong anti -static capabilities have long life, so the price is high. LED lamp beads that are usually anti -static than 700V can be used for LED lighting.

5, leakage current

LED lamp beads are unidirectional conductive light emitting body. If there is an reverse current, it is called LED lamp beads with large leakage currents. LED lamp beads have a short life and low price.

LED lamp beads are widely used in lighting lighting, LED large screen display, traffic lights, decoration, computers, electronic toy gifts, switches, telephone, advertising, urban glittering engineering and many other production areas.
