Topic: UK source of buck-pucks. (Read 885 times) previous topic - next topic


I'm looking for a source of a three PWM-able buck-pucks (350mA) in the UK.
I found some Luxeons in a drawer, and I want to do something with them.
Does anyone have any recommendations, please?

The only place I've found that sells them is here:


Their info says they'll ship overseas to 'some countries'. ┬áIf you place an order, they'll either ship it or cancel it and not bill you.  It's worth a try.  Maybe email them first and ask about it.



I've heard of hockey pucks
I've heard of pass the buck
but buck-pucks must be a British thing  ;)

Never having been oppressed by Napoleon, we continue to drive on the correct side of the road, as do all civilised countries, and Australia.

OK, modified question, if I can't find buck-pucks, what other options do I have for driving three separate strings of Luxeons at 350mA, and a PWM frequency of around 300Hz?
(Confession time - I'm not driving them with an Arduino)

Check dealextreme.com.

look undere "Electronics" and then under "DIY parts".

They have some comstant current source LED drivers. Cheap + Free world wide shipping :-)

I don't know if they are PWM-able though.
