Brighter Blue LEDs

[Gerbil333]

What's the point of this? The blue LEDs in my case were already way too bright, so I unplugged them.

Duh, didn't you want blue taillights and turn signals? Screw red, blue's where its at.

LEDs are used for home lighting and they are getting much brighter and cheaper to produce.
They use less energy, have a long life and develope less waste heat. This is just a progression.

The PD is very particular about who runs blue lights. On the rear:roll:

On a side note, i just ordered 3mm LEDs to replace the insanely bright ones in the two Sunbeam fan rheostats i have.

Blues are the weakest link, besides the violets. There are many applications which want brighter blues. For example: my company (barcode decoders) is doing a cross hair targetting system in blue. I am always searching for brighter/ more efficient blues among other colors.

Also, isn't it normally blue used to pump the phosphorous used to make the whites? Surely you can see the need for brighter whites.

You may want to use the LEDs for lighting - signage, daytime visible indicators, backlighting of LCD TVs, etc.

Indicator LEDs like the ultra-bright blue ones that you can get everywhere these days are not powerful devices. They merely produce a very narrow, very intense beam - rather like a high-brightness flashlight. You couldn't use those for actual illumination.

You can get high power LEDs, but they are quite specialised. I'll include the obligatory pics of my collection of uber LEDs:

Make, model, price of said LEDs?

Yeah -- those Sunbeam Rheostat lights are BRIGHT!

I installed two of those "string-of-pearls" $7/ea. from Sunbeam behind the modder's mesh in my case front. I put automotive aluminum tape ("almost 'chrome'!!") on the chassis front, and on various surfaces of the plastic bezel behind the modder's mesh.

Sucker looks like something out of "ET" now . . . glows so bright you'd think God were coming for you in your sleep . . .

I was never enthusiastic about this "pimp-rig" stuff before. But each of the Sunbeam units only pulls about 20 mAmps of current. Why the hell not?? I'm just not quite ready to substitute "tangerine-flake" auto-enamel for IBM-beige yet . . .

Why blue? I thought red light works best for those applications because it improves the contrast of the image compared to blue light. Brighter whites, yes, I see many purposes for that.

blues the base for white leds which is why it matters.
