    Hi all ...

    I need help with this high powered LED im buying, the data sheet is on this site aswel.

    http://uk.farnell.com/ledengin/lz1-00db00/led-5w-dental-blue/dp/1678946

    Basicaly could some one please recommend a driver or resistor I need to run this LED, i was going to power it by just using a 12v adaptor.

    I did speak in online chat to a guy from the site he recommended this driver.

    http://uk.farnell.com/xp-power/ldu2430s1000/dc-dc-led-driver-constant-i-1000ma/dp/1738296

    But as you can see the LED is £15 to buy so i want to make sure I get it all right.

    any help would be great guys.

    With that driver you do not need a series resistor.

    But you do know that you need to heatsink the LED, right?

    Hi Steve.

    Thanks for the reply.

    So your saying the driver I listed is the correct one for the LED. I hope it is because I have already purchased it.

    Do you know what heatsink I should be looking to buy to use with the LED . . . be very greatful if you could point us in the right direction.

    Check the datasheet for the LED, it should tell you what you need.
