What are the sunny white LED's called out in the lighting industry. If I wanted to buy a bulk quantity of the sunny whites what name would they be called like on that auction site or a LED distributor. I would like to buy at least 50 3mm sunny whites and at upwards of $1.30 each + it would be a little cost prohibitive from the model RR distributors.

Sunny White or Golden Glow are the two most common sold for model railroad purposes.
I get most of mine from either of these sources, which are much cheaper than hobby shop prices:

Sunny White will be something like fluorescent lights, and the Golden Glow are equivalent to incandescent bulbs.
You'll have to go by color temperature. I found a web site that tested all sorts of LEDs (but mostly seem to be the high power ones used as flashlight bulbs),, but they did test a Richmond Controls golden-white and reported a color temperature of around 3400K. The bluish-white LEDs seem to be 5500K and up. I'd guess a sunny white would be somewhere in between those. The lower the color temperature, the more yellowish the LED will be. The higher, the more bluish tint it will have.

I bought 100 warm white 3mm LED's from that auction site beginning with E from China. It took 4 days short of a month to get them but they are the sunny white LED's I have bought from DCC sites on the net for upwards of $1.30 each. I just did some tests and they are identical to the sunny whites. Now for the good part they were $2.99 plus $4.00 S&H so they were only 6.99 cents each. They even came with 100 1000 ohm 1/4 watt and 100 470 ohm 1/4 watt resistors. It was a shot in the dark experiment but I figured its only money eh!. I tried the 2 resistors and there did not seem to be much of a difference in brightness between them both were very bright and did not have a hint of blue in the light I am very happy with them.
Industry standards seem to label them as Warm White (slight golden tint), Cool White (those bluish whites) and Pure White - which is just that .... pure white light with no color over-tones.
I too have purchased LEDs from the Asian market - both direct and through that auction site. Something must have happened with the above poster's order .... I've always received mine in less than a week, yes - all the way from China !!!

I agree. Shipping from China is faster and less costly than shipping with-in Canada, for the most part.

In addition to these two places mentioned, I bought 100 each kind of white from here:

Around $0.15 each, haven't had a bit of problems with them. And I don't have to send my money to China.
