Nominal 3V LED lamp beads, in fact, different colors have different requirements for current. Yellow light requires the smallest current, followed by red, green, white, and blue. If the current is too large, the wick will burn.
Using 2.4V rechargeable battery, yellow light is easy to burn, because even if the voltage is not high, but the current is too large, it will still burn. When using the button battery, although the button battery voltage is 3V, the button battery discharge current is very small, so the 3V LED lamp beads will not be burned. Therefore, when using LED lamp beads, you should choose a suitable power supply, pay attention to the voltage and current.
