Why are white and blue LEDs more expensive?

supremetronic sell white/blue/purple + all cool color LEDs for $1.50 each
whereas the red and crappy colors go for 20 cents each
thats a rip off consider that i can get white/blue LED at dollaroma for a dollar with batteries included
are they jacking up the price or do they really cost more?

Supply and demand. White and blue LEDS are in more demand perhaps?

White and blue LEDs actually cost more to make, I think only in the recent few years has the breakthrough came that allows them to work.

yeah at the hardware store i work at, during christmas out white/blue LED strings of lights are usually $5-$10 more for a package. they told us (the PK guys) that it was because in order to get the blue and white, they must go thgrough every other colour first. our reds, greens, etc were all cheeper and the same price.

aswell, i dont know if you've ever noticed, and on newer LED's .. my phone for example, the white LED is vary white. the ones we had for last christmas had a blueish tint to them.

LED's are the future. once we figure out how to direct them and make them brighter, they'll be replacing bulbs for headlights. many car manufacterers are already using them for rear, brake, and signal lights.

Slightly different material is used , and yes that is why the cost is slightly different. Plus Blue/white is a recent developemnt. Pink/Purple is even newer I think.

yeah material is different as well as the light output and current needed to produce the light .

but if u are looking for leds buying from stores or even hardware stores they will always rip u off. a while back i was looking around for a dozen leds ( needed about 24 for a project of mine) all places downtown had the cheapest "superbrights" at 1.50 - 1.00 . meanwhile if u were to buy them off the net in the links i provided above they cost about 20 cents each .

radio shack , active electronics even places in chinatown hugely overprice there leds .

I believe its because those colors are the newer generation of LED's. I havent used them in any of my electric circuits but when I started playing with electronics back in like 95 96, all my LEDs were red.
