Same wavelength, same color. Then the price is high:
White light is divided into warm color (color temperature 2700-4000K), positive white light (color temperature 5500-6000K) and cold white light (color temperature above 7000K). Europeans prefer warm white.
Red light: band 600-680, of which 620,630 is mainly used for stage lighting and 690 is close to infrared light.
Blue light: band 430-480, of which 460 and 465 stage lights are used more.
Green light: band 500-580, of which 525,530 stage lights are widely used.
Frequently asked questions about led lamp beads;
1. Problems caused by abnormal power supply:
Check whether the power supply works normally and whether the indicator light is on. If not, please check whether the power supply is connected correctly.
Check whether the power cord of the lamp bead is connected with the positive and negative poles of the power supply and whether there is phase inversion. If the above problems exist, please connect them correctly.
2. Voltage requirements:
Nominal 3V LED lamp beads, in fact, different colors have different requirements for current, yellow requires the smallest current, followed by red, green, white and blue. Excessive current will scorch the wick. Charging the battery with 2.4V is easy to burn, because even if the voltage is not large and the current is too large, it will burn at will.
