This innovative, eye-catching colour change LED contains an inbuilt IC that causes the LED to cycle through the red, green and blue elements individually and then in combination.
Diffused lens
Colour cycles in 33s
Ideal for use in warning devices, indication panels, alarm systems, mood lighting and toys
Q. Hi do I still need to use a resistor with these if I use 4.5V or 5V?
A. Hi Andy, thank you for your question. This LED is designed to work with a typical voltage of 4.5V (3 x AA batteries) 5V is it's absolute maximum. As these have an integral I.C the use of a current limiting resistor is not advised as this method requires a constant current to be drawn and with these LEDs the current varies from colour to colour.
Q. What is the time in seconds for the LED to cycle through all 3 colours? The catalogue says it cycles at 1.5Hz, but the 3mm and 10mm LEDs have cycle times of >30s. 1.5Hz seems a bit quick!
A. The cycle time for all 3 colours is 30-40 seconds MAX.
