Q:
Do these 3W White Power LED Star require a resistor if so what size.
Asked by: Martin Tones
A:
Hi Martin,

Thank you for your question, you would likely need a resistor with 2.2 Ohms. If you look on the link below we have a few more details.

Q:
Hi there, I want to try and make a light to use on my mountain bike....I want to make it as bright as possible....would it be possible for you to put together a list of products from your site and I will buy.... I am looking to make a light at least 2000 lumens....

Asked by: David
A:
Hi David, I believe I spoke to you on the phone earlier today, unfortunately none of our items would be suitable for this as although you could create a circuit it wouldn't be practical.

Q:
would theses unit be suitable for use as a flash with the raspberry pi camera I do know how to wire them to be switched via gpio
Asked by: Terry
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, Using_a_Kitronik_3W_star_LED.pdf

Q:
I am looking to connect six of these into a ring format. Should I connect them in parallel and use a PSU? Thanks
Asked by: Lizzie
A:

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.

Q:
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.
Asked by: Phill
A:

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’, Using_a_Kitronik_3W_star_LED.pdf and on the second page it shows what power supply should be used.

Q:
Is this LED able to be dimmed?
Asked by: Joshua Budgen
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.

Q:
Does this LED require a heat sink?
Asked by: Keith
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.

Q:
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?
Asked by: Keith
A:

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

Q:
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.

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 how-to-use-3w-star-led

Q:
If used with the USB power lead what size resistor will I need? Can USB produce enough current safely?
Asked by: stuart
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: how-to-use-3w-star-led
