DIY LED Using 10 Watt Arrays

[Tony Ooi]

Thansk for your explanation.
Te 12V DC power supply, the potintiometer you mention , is it the the plastic which have philips screw head?
my dimmer just arrived yesterday. I have yet to open up to inspec what is inside , but it felt like almost nothing and very light wieght. I have LED which spec at 10watts(running at 10V, 1A current). Theoretically should able to handle up to 8 LED per dimmer base on the label stated there 8A. For safety reason, i might just want to keep 6-7 LED per dimmer.
