How to use an LED correctly: If you use a power supply like a regulated DC PSU, always use resistors to adjust the voltage at or below the rated level. Do not supply above-limit voltage because you will only get a small raise in brightness but the LED will become less durable. Don't forget to verify the direction of the LEDs when you connect them.
