These power LED stars offer an extremely high light output in an energy efficient way. The power LED comes mounted on to special PCB star that acts to draw heat away from the LED, therefore extending it operational life. This makes them perfect for many lighting applications, a datasheet can be viewed detailing a few options.

Forward Voltage: 3.0V - 3.4V
Angle: 110deg
Luminous Intensity: 45000mCd
Colour Temp: 2700K - 3300K

hello, one of my pupils would like to use two of these 1 watt LEDs (code 3547) using your 12v power supply. (code 2265) they would also like to dim the LEDs using a 10k pot (code 3010-10K) which power resistor would you recommend to use ?

    Hi Phill, With regards to using a potentiometer to dim an LED you would only be able to dim a small section of what the LED emits, as such you would likely have the LED on, it would then dim slightly and then go off as you turn the potentiometer. If you wished to try this circuit you would need to use the following potentiometer, 3005-50R,

    You would connect this in series with the two power LED stars, and then put the 10 Ohm power resistor in parallel with the 2 LED stars and potentiometer.

Can this LED be used with a 3v penny battery? I know this is less than the forward voltage but I'm assuming that the LED just won't be as bright rather than not work at all. Thanks.

    Unfortunately you wouldn’t be able to use a coin cell battery to power this, the LED star draws 310mA and the coin cell batteries can only supply 200mA.

You have indicated a 10k linear potentiometer can be used to dim the LED. Is this wired in series to the resistor? If not could you provide a circuit diagram to show how this can be done? Thanks.

    The following link explains how you would need to connect this up, also it explains a little more into how it works,

I'm a A Level product design student and we have an LED lamp project, I was wondering if i were to wire 3 of the 1 W LED's in parallel to an electromagnet if a 12 volt power supply would be strong enough to run all of this?


  • Posted by Michael Lockhart on Monday, 8 February 2016

    It would depend on the current of the supply, and also the current that the electromagnet uses. You might get some back EMF from the electromagnet, so it would be worth putting a beefy blocking diode in line with the LEDs

Hi I am a teacher of GCSE product design with the project of lighting and was hoping to secure two alternative methods of lighting: a mains/USB powered circuit such as the CREE LED Kit you supply and an equally bright star LED powered via a battery therefore a portable option. I was wondering as this is the LED featured in the USB kit could it be powered by a battery source and if so what would be best and would a resistor be necessary. Also would this be the best option for a bright battery powered light or do you recommend an alternative. thanks Sanj

    Yes you can use a battery to power the LED, you can power it from either AA batteries or a Polymer Lithium Ion Battery. This would give you around 3 hours of battery life. It would still be recommended to use a resistor, and this would depend on the batteries you wanted to use.
