Any time, I keep a few in stock...

Resurrecting this old thread-- PatMat had pointed me to it form my thread about lighting my Lightship.

This thread mentioned the holiday lights- but they aren't in any of the stores around here at this time of year.

I just found a possible source for the concave white LEDs:

And look at the clearance page-- they have red and green strings!

I have used SMT LED's for a side mount. You can get all different sizes and colors.
I use 2 soldered together for the "Halogen" spots on my push tug.

Here is an article on what can be done with LED's. It might give someone an idea coming up with something new...

Try the long version.

New for 2011- Warm White minis!


I was excited back at the beginning of this thread about these inverted-cone tip Xmas LEDs, because unlike regular LEDs, they shine 360 around... regular LEDs are more like flashlights, with all the light out the tip.

Problems- these 5mm (3/16") diameter LEDs are hard to use in smaller models... though they are quite OK in about 1:24th. And they have that blue tint, just not right.

But I walked into my Sam's Club today, and lo & behold, warm white mini LEDs with inverted cone tips!

These are 3mm (1/8") diameter, so they'll be useful in even more models.

Yay.

20 bucks will get you 200 bulbs... enough for a lifetime (or one of Leen's offshore tugs).

Another comparison- size of mini 3mm vs 5mm.

Also- the mini bulb casings will make perfect welding gas bottles in 1:72 scale!

Thanks for the info Pat!! Now that the season is here I will make sure to pick some up along with the usual X-mas supplies.

It's that time of year- go stock up on these inverted cone tip warm white LEDs! Buy one string, you'll be set for life...

Pat, how hard is it to get the bulbs out of those green/white plastic holders? Can you theoretically get all 200 bulbs out intact or are you looking at substantial attrition from ham-fingers?

More an issue is poking yourself on the leads. Use pliers...

Saw some more Xmas LEDs today, might give you some ideas.

One is just another source of 3mm inverted tip white bulbs... though you really want to make sure they aren't the old blue-white, but rather a true white.

The others use LED chips (which you can also buy loose). These are tiny, 1 maybe 2 mm for example... they have solder pads on either end of the chip, and the LED is on the top surface... they're intended for surface mount soldering onto a board. But here, they're soldered like rungs on a ladder made of skinny wires... not sure where the required resistors come in, can't be the wires themselves...
But each LED is encased in a drop of clear material... I've seen white and colors.

I found a bunch of the chip LED's at the dump though I have no idea how much voltage they would need. Must be a strand that has 30 or so LED's on it.
