Hi there,

new kid on the block here...............i'm trying to use the led wizard thingy.

I'm looking at building the 3 point clip system, using a 12v supply and using LED's with a max forward voltage of 14v and a forward current of 8.5mA, both values as quoted by supplier. When i put these values into the wizard.......nothing happens......HHEELLLPPPPPPPPP

I don't know, but those led values just don't seem right...

But anyway, assuming that those values are correct and instead of max forward voltage, it's the only froward voltage (the voltage necessary to make them work), you will need a battery of 15v at least... that's why the wizard doesn't work.

I suggest that you confirm those leds values first, they don't seem correct.

Hi Jorge,

Thanks for the reply, below are the details from the suppliers website. I would appreciate any help that you could give in explaining the values to be entered into the wizard, and what results i should expect

Thanks...............potgut

No problem.

Forward voltage:    2.5V - This is the value for the led wizard, with the same name (minimum tension that you need to feed the leds, so that they become active)


Forward current max.:    25mA - This is max current they support before they "burn", you have to introduce a lower value in the wizard. I would go for 20mA, since higher the current, higher the intensity of the light, but at the same time shorter life time... so it's really up to you.

The rest of the values don't really matter, unless you want to compare them to others.

Good luck with your setup.

Thanks again Jorge, i am very grateful for your help on this one.

Entered the values advised and got the results. Off now to buy the parts.

Will let you know when its built and working.

Thanks again.......potgut
