Golden white LED's

[river_eagle]

got them at target right after thanksgiving 60 +4 spares for 7.99

100 string for 11.99

inverted cone type, use as is for general lighting, sand/file/grind off cone to use as headlamp, tje ones inside round globe a bit smaller than 3mm size. 

similar prices at Wall-E.

Only a matter of time until Walthers or someone else buys a bunch and sells them at 4 times the price.  They could advertise them as pre-wired lighting and cut the end off of the string.  Then add instructions to cut the bulbs off as needed.

If you don't mind waiting until Christmas one can get strings of 50 of them for about $7.

 

Golden-whites?  Maybe standard white.  I have never seen golden-white or Yeloglo LEDs used on Christmas trees.

 They do - and they seem to be the ones sold out first. I guess peopel have caught on and realized the bluish-white one don't look so great draped over the bushes. I've seen them - what I haven't seen is the awesome price people pick them up for.  By the time WalMart et al put them on clearance around here, it's a few colors and some cool white, nary a warm white set to be found - and i've played treasure hunt on the shelves, hoping to find the last overlooked set. At regualr price, there are usully plenty available, but they aren't such a deal per LED at regular prices.

TZ,

I guess it's possible that a 200 ohm increase in resistance might produce a more yellowish tint to an LED - i.e. at least a "warm" white one.  Yea, sounds like a good science fair project to me.

The surface mount LED's are usually used when there is a light channel used. In those cases you don't see the device in the lens.

On the xmas tree lights, they call the golden ones "warm" whites

the pure blue-whites are "cool" whites.

corner drugstore has cool white, others have warm whites

I could be reading it incorrectly but it seems like the "dayglow white" LEDs that Renegade is referring to are still whiter than the golden-white or Yeloglo LEDs.  Perhaps good for newer diesels but not so much for steam locomotive headlights.

Possibly, but when Charles first found these I had just purchased some genuine Yeloglo and begun to use them.  I could not tell much if any difference.  Now I am wondering if the "yellowishness" varies with the resistor value.  I usually run 1200 ohm instead of the normal 1000 ohm that most people use.  Not quite as glaring....  Now if I only had a spectrometer I could test that theory or give it to a student for their science fair project.

Then you haven't looked to closely....They don't call them Yeloglo of course. Ummm Renegade1c found them originally http://cs.trains.com/TRCCS/forums/t/140556.aspx?PageIndex=1

Point of clarification: 3mm LEDs for standard headlight applications come with leads attached. The surface mount LEDs are the ones that are sold with or without leads attached.  These are miuch smaller than the 3mm and are rectangular shaped. 

If you buy the surface mount LEDS, I agree with other posters, cough up the extra $ for the ones with leads attached...I have soldered leads on these puppies...not an easy task that I would care to replicate.

Here is a shot of a Surface Mount LED in a brass loco headlight mounting. Looks great when it is on, looks like someone stuffed a tiny box of kleenex in the loco head light when it is off.  Needs a lens...

Richmond controls is a great company...

 

If you don't need small headlights, I have bought golden white 3mm LEDs in lots of 100 for very cheap on Ebay....

JRP,

I like the 3mm Yeloglo LEDs from Miniatronics.  Some g-w LEDS are too orange in color.  The Yeloglo LEDs have just a slight tinge of yellow to them and are very realistic.

Thanks. I just found richmond controls and agree on the leads attached too. I'll give them a try. JRP

Make sure you get them with leads attached.  Makes life much easier.

Yep, I'll second that.

Anyone know some good sources on where to find and buy "golden white" LED's at reasonable prices(either on line or at stores)? Thanks. JRP
