The idea is good . However the resistor must be of 4 or 5 Watt to work properly. Because : P=I x I x R.

you need 30 ohm resister not 10 if your using 12v dc as a power source.

for your information i used metal film resister because it was available that time. Metal oxide film resistors operate in a wide range of resistors and can withstand a higher temperature than the resistors of the carbon film. Noise Design In contrast to carbon film resistors, metal oxide film resistors has a low noise design. They keep the minimum current. Therefore, it ensures less noise.

For 12V power supply: - Connect 4 LED in series, so each LED will only receive 3V. It can have ~60-70% of max luminace but with less heating. - To get higher luminance, connect 3 LEDs in series with 10Ω resistor, it is 20% brighter than 4 led in series, but the resistor will draw almost 400mW of waste heat, and the LEDs will have shorter lifespan.
