    Hi Cian, The problem you have is this LED is designed to run off a 5V battery, and using a resistor with this is very difficult due to the fact that the current draw changes. As such if you needed to use a 9V supply for your circuit you would be best to use a 5V regulator to drop the voltage down for the colour changing LED.

    Hello Indrasena, The colour changing LED has a maximum voltage supply of 5V’s. As such you shouldn’t’ use a supply that has a higher voltage than 5V’s. We also wouldn’t recommend using a car battery to power a homemade device as a car battery can provide a large amount of current and could be dangerous.

    A:

    You wouldn’t be able to place a number of the colour changing LED’s in series to allow you to use a high rated power supply. This is due to the forward voltage constantly changing while the LED cycles through the different colours, as each colour requires a different forward voltage. As such if you had a number of these in series you could either not have enough forward voltage for each LED, or when they require a smaller forward voltage you could cause the LED’s to become damaged as the supply voltage then becomes more than what is required by the LED’s.

    I’m very surprised to hear that you are having issues with the colour changing LED’s. If you can email your order details, including your order number (being 03) to sales@kitronik.co.uk we will be able to look a little further into this for you.

    The voltage is ok, you should check the maximum current your transformer can supply though. If it is over 300mA you should be fine

    A:

    Although it is possible to run this off a high voltage using resistors it would cause issues with the LED. This is due to the fact that each colour requires a different current, by having a resistor already in the circuit would mean you are limiting the current twice, and would likely stop the sequence running correctly.

    You wouldn’t be able to run these LED’s at a higher voltage of 5V’s and use resistors to bring the current down. This is due to the fact that each colour requires a different current and as such you wouldn’t be able to limit it without limiting the way the LED works.

    The LED’s are fine working at 4.2V, it has a built in current limiting for any voltages up to 5V. You will be fine to put the LEDs in parallel with the batteries and you won’t have any problem. The wattage of the heater want make a difference, as the LED’s will only draw about 25mA each when wired in parallel with the batteries.

    You wouldn’t be able to wire this circuit in series as you would need a supply voltage of 200v DC to give each LED 5V. The best option is to wire the circuit in parallel. Please be aware that each LED can only be run at a maximum of 5V.

    Hi Barry, The LED’s shouldn’t be burning out as they don’t need a current resistor and they can handle a power supply of up to 5V. To understand why this might be happening I need some more information, such as the rating on the power supply and ideally a photo of the circuit. If you can supply this to me in an email to support@kitronik.co.uk then we can try and solve the problem.

    A:

    The sequence is as followed: Red, green, blue, yellow, cyan, magenta then back to the beginning of the cycle. As the change is a gentle fade you do get colours between these in the cycle, such as the fade between red and green will produce an orange/yellow glow for a short period before fully changing to green. The time between each change varies depending on what the next colour in the sequence is, so the amount of time the colour stays on for does vary slightly although there isn’t a large difference in time variations.

    A: Hi, they all go out of phase after a few cycles. It's the same sequence for each LED but the timings on each LED are very slightly different.

    A: The capacity of the CR2032 coin cell is 200mAh. Technically these batteries are designed for keeping clocks on time when the power fails and as such state that the max current draw is 10mA. If you take more than this it won't be a problem however the internal resistance of the battery will mean that it will limit the current and the voltage may drop a little. This can be seen when the cell is running low, by the LED dimming and then voltage dropping to the point where the cycle starts again. The current taken by the colour changing LED will depend upon the colour that it is showing, lets use a typical average value of 40mA. In which case the cell will last about 5 hours (40mA per hour for 5 hours = 200mA capacity). Your simplest option for a longer life would be 3x AA batteries. A good AA battery will have a capacity of around 1500mAh so would last for around 38 hours with a colour changing LED. Mobile phones use lithium ion batteries which would be good choice on size, but whilst these are compact circuits for charging them are very complex.

    A: It depends on what you mean by "safe in lit candles". We don't stock any LEDs that won't melt or stop working at very high temperatures, but if it would be for example in a candlestick under the flame it would function fine. The key thing is keeping any batteries away from heat or flames, they can leak or even explode.

    A: Hi, these particular ones are ok up to 5V. They have a typical forward voltage of 4.5V so they are a little different to the 3.4V ones you saw elsewhere.

    A: Hi, 2.2V won't power a colour changing LED. It may light up very dimly or not at all. If it is a 1.2V battery though it suggests the voltage is being boosted some way. Your multimeter would read the average voltage and not the peak voltage. The peak may be enough to light the LED. Without knowing more about the lamp it's impossible to say.

    A: Hi Dave, the LEDs have microcontrollers in them which determine the timing, due to very slight manufacturing differences the timings are all different and they don't stay in sync. You can try the RGB LEDs we sell, those you have full control over and can get virtually any colour out of. https://www.kitronik.co.uk/products/components/leds/leds/colour-changing-and-rgb-leds/rgb-full-colour-led-5mm/

    A: 3xAA batteries will run a single colour changing LED for about 80 hours. If it's in a bathroom you probably want to avoid using mains transformers as they are not waterproof.

    A: Hi George, Can I ask how you connected the LEDs? Where in the circuit are they? The amount of current the LEDs draw varies as they change colour and this is likely causing the power supply to fluctuate which in turn is upsetting the IC as it tries to decode the radio signals. Are you powering the circuit from a battery or the mains? Is it one of our FM radio kits?
