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 applications.

Forward Voltage: 3.5V - 4.0V
Angle: 110deg
Luminous Intensity: 67000mCd
Colour Temp: 6000K - 7000K

Question:

Can you suggest suitable batteries to power these LED's? I'll probably have about 6 of them in a scale model to light it from the inside. Thanks in advance.

    Hi Phill, Unfortunately due to the current drain of the LED star batteries are not recommended as shown in this datasheet in the section ‘using the LED’, https://www.kitronik.co.uk/pdf/Using_a_Kitronik_3W_star_LED.pdf and on the second page it shows what power supply should be used.

Question:

Is this LED able to be dimmed?

Answers:

  • Posted by Michael Lockhart on Thursday, 4 February 2016

    You might be able to use a potentiometer, however you would need to ensure this is rated to at least 3W. You might find though that as you turn the potentiometer there is little difference in the brightness and then suddenly the Led will turn off. The best way to do this is to use a micro-controller to quickly turn the LED on and off.

Question:

Does this LED require a heat sink?

Answers:

  • Posted by Michael Lockhart on Thursday, 23 July 2015

    No you don’t require a heat sink, the power LED comes mounted on to special PCB star that acts to draw heat away from the LED, therefore extending its operational life. However please note during use the star LED and resistor will become hot and as such shouldn’t be touched.

Question:

Would a 5v 1amp USB charger be suitable to power this LED using the curcuit https://www.kitronik.co.uk/blog/how-to-use-3w-star-led, if not would a 5v 2amp charger be sufficient?

Answers:

  • Posted by Michael Lockhart on Monday, 20 July 2015

    The 3W LED star draws around 300mA, so a 5V 1A power supply would be suitable.

Question:

Do you sell a kit to run this LED. What power supply would be required. If no kit is available could you provide the parts requied to produce a simple lamp. THANKS, Howard Bevan Afon Taf High School.

    There isn’t a kit for this one but if you use this tutorial on how to use a 3W LED star that shows the components required for the circuit, https://www.kitronik.co.uk/blog/how-to-use-3w-star-led/
