LED Pin Spot Lighting

**MrNightmare** · 03-30-2009,08:26 AM

Does anyone know where to get those small LED Pin Spot Lights? The are very bright but to not flood the rest of the room with light, only the spot you wish to light. Also, the are very small and easy to hide. I've seen these in many Haunts last year, but I can't find where to get them...

Just make them yourself. I use a small piece of black plastic tubing and mount the LEDs inside. Attach the appropriate resistor and a 9 volt battery snap and you're good. Here's a couple of pics:

Otaku,
I'm going to have to build a few of these this year. They look fairly easy to build. I'll have a few questions for you down the road. I'm working on other projects right now.

How will I know if I have the appropriate resistor???

You could ask the salesman when you go to buy the LEDs what size resistors you would need?

or I could use this calculator:

You need to know the forward voltage and the current draw of the LED. Plug the values into this wizard:
LED series parallel array wizard
and it'll show you how to wire the array. If you're using a wall wart instead of a 9 volt battery, just be sure that the wart has enough current to power all the LEDs in the array. In some cases I didn't use a resistor at all - if the forward voltage was close to 3VDC and I was using 3 of them, I just wired them in series to the battery snap. It's a little rough on the LEDs but I haven't had a failure yet.
