How to connect LEDs properly: If you are going to use a power supply like a regulated DC PSU, remember to use a resistor to adjust the current below the rated level. Never supply excess current: the brightness will only increase by a just a little bit but it will shorten its lifespan. Don't forget to verify the polarity of the light emitting diodes before soldering them.
