Source for LEDs w/ long leads

Evans design offers their LEDs with 8" or 14" leads.

Evans Design LED's will probably not do well at the voltages he specified.  I'd consider just using #3 wire-wrap wire (the same as Evans uses), and wiring your own resistor and diode (if AC).

Are you running AC or DC to power these?  Note that white and blue LED's require around 3V to light, red, yellow, and green typically require around 1.5-2.0 volts. 

Like I said, the color determines the operating voltage.  Note that you should virtually always have some sort of current limiting for LED's.  Once they reach operating voltage, a small increase in voltage with no current limiting will result in much higher currents, usually exceeding the ratings of the LED.

I've never seen white LED's that will do anything at 1.5 volts, so I'm not sure what you have there.  I looked on their website, but I didn't see any LED stuff for sale, do you have a link?

John, I will re-check the packaging when I get home.  I'm positive it said 1.5 volts and warns against using a 3 volt source and wiring in series to limit current.

I didn't think Tichy was in that business, but they must sell someone else's product.

It’s so easy to just wire those Evans LED’s directly to the accessory terminals on your AC transformer.  No special wiring or diodes needed.  I’ve had no problems running those Evans LED’s using 12-14 volts AC from my post-war ZW’s.

John, my preference would be for 3VDC LEDs (white) with long leads.  My power source is an old computer power supply with 3VD, 5VDC, and 12VDC outputs. 

I'm trying to find LEDs that I can use for street lights (on arms) on telephone poles.  That's why I need the long leads (and very small gauge wire).

Here's some ready for 12 volts: http://www.ebay.com/itm/30-pcs...;hash=item232197ded8

Here's some 3V with wires: http://www.ebay.com/itm/20-pcs...;hash=item1c36596bb8

John,

I took a good look at the package and here's what it says:

"Tichy Train Group" is in the center of the label, but surrounding it is "Micro-Scale Models Inc."

And the website is www.micro-scale.com

It also says that this is a 1.5 volt clear lamp for visible gas pumps.  Avg lamp life is 5,000 hours.  So maybe this ISN'T an LED after all.

Correct, that's not an LED, I'm virtually certain that's simply an incandescent bulb.  Sounds similar to the kind that Harry Henning has as step lights on a locomotive, I forget where he got them, but they were 1.5v bulbs.
