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

    Hi Lizzie, You would need to connect them in parallel, and you would need to defiantly use a power supply. One that is rated 5V 5A.

    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.

    A:

    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.

    A:

    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.

    A:

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

    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/

    A: You cannot use this LED from a USB power lead. It requires too much current. You can use the 1W version through as detailed here: https://www.kitronik.co.uk/blog/how-to-use-1w-star-led/

    A: The star is 20mm across. If you click on the images just under the main product image there are some mechanical drawings.

    A: Hi Terry, The LED may be suitable to use as a flash, it has a Luminous Intensity of 67000mCd and has a viewing angle of 110 degrees so a fairly large viewing angle. However you would need to ensure the LED is connected up correct and follows something similar to the datasheet in terms of power supply and also a power resistor, https://www.kitronik.co.uk/pdf/Using_a_Kitronik_3W_star_LED.pdf.
