Thank you for your email, unfortunately yes I think those LEDs are quite dead now they have had 12V run through them. This circuit is reasonably resistant but with that much power it is likely dead. Generally these kind of kits have a very small switching circuit inside to change between three colours of blue, red and green. At 12V either the switching circuit has burned out or the other two colours has as well.
These LEDs are only 750mcd which means they are not the brightest LED so probably that was the correct brightness when you had it at the 5V.
I want to connect this directly to a 3V lithium battery - can you confirm that this is enough voltage for the LED to work and cycle through all the colours?
Hi Adrian, This should be fine, we use the 5mm version of this LED in our electro-fashion range and this runs off a 3V coin cell battery without a problem.
Hi Carol, Unfortunately the only colour changing LED’s we have are diffused. The only other alternative we have is an RGB LED, colour changing LEDs you would then use a micro controller to change the colour that the LED outputs.
need to use http://www.kitronik.co.uk/products/components/leds/leds/colour-changing-and-rgb-leds/rgb-led-5mm-common-cathode-pack-of-500/ or the common anode version and some circuitry to control the timing of the colours.
