(This kind of relates to my previous post 'Heatsinking a 3W Luxeon').
Anyone know anything about BuckPucks for Star LEDs? I've never used one before, and I'm confused about the voltage requirement. I am not using batteries.
I want to use a Luxeon 3W (is that the Luxeon III?) Star LED. I have a
1000mA BuckPuck that I also purchased which apparently accepts voltages between 5 and 32V. There's a couple of questions about the connectivity of these two devices that remain unanswered . yet I have been searching frantically on the web!If I want to run a single 3W green Luxeon Star LED using the 1000mA rated BuckPuck, is the voltage applied to the BuckPuck important? Hypothetically speaking, say if I apply 12V to the BuckPuck, does the LED also get the 12V or does the BuckPuck reduce it down automatically to suit the LED's requirements without me doing anything? It doesn't say anywhere (that I can see) in the LuxDrive 3021 BuckPuck Product Manual that proper voltage input is important according to the LED configuration, and what you need to do.
I will not be supplying the full 1000mA to the LED - I will be reducing the power down a bit using the BuckPuck's optional pot. Hopefully this would allow me to reduce the power a little somewhere around 850-900mA.
Thanks
Jason.
