Review on High-Quality Haobase 50pcs Mixed Colour 5mm LEDs Pre Wired Light Bulb - Bright 12V 20cm Mini Lamps by Larry Ton

Revainrating 4 out of 5

Make sure the current limiting resistor can be rated higher.

These LEDs are bright enough when powered from 12 to 9 VDC. The current limiting resistor is small, 1/8W. Open 12VDC at 100mA. it will be very warm to the touch. I don't know the value of the resistor connected, I haven't taken it apart to read or measure it. I used them to replace the "wheat grain" bulbs in my radio. I had to add an extra 1kΩ 1/2 watt resistor to the lamp. Works great after this supplement.

Pros
  • Easy to use
Cons
  • There are other interesting options.
