LED Brightness

There has been some talk on LED brightness, well since I am still too poor to afford any and take pictures, I decided to take pictures of some LEDs I already had, namely in my computer, to show you the typical brightness of them. I took them at varying light levels to give you a good idea:





Most of the automotive bulbs are 4-LED and some 9-LED, these are single LEDs each, so keep that in mind.

Where are the LEDs located? The only LED I remember in my desktop is on the network card, but that was years ago.

Reading Topic: LED Brightness

Those are some bright LEDs...I think the latest and brightest is the "luxeon", but couldn't find any that were made for auto applications yet, so far only in flashlights. The next brightest are the 5mm Nichia type. I think they what most bright LEDs are made of today. And then there's the older type LEDs that are used as indicator lights on things from laptops to cellphones and computers. The LEDs above definitely are bright. You sure there's only 1 of them in there?

Is that LED's or Neons? Led's are not this bright. And as I read elsewhere, LED's do not actuatully give you more brightness. Only nicer look, instant on/off, they don't heat up, longer life, and crisper look.

Those are LEDs on mine, although you can clearly see the cold cathode on the door. If those are not LEDs, then those are some funky bulb-shaped neons... :)

Ofcourse there are LEDs this bright. There are blue LEDs so bright they are like flashlights...

I have a decoration light in my office, it has seven blue LEDs and it lights up the entire office when I turn off regular light. Pretty cool.

I, in fact, have an LED flashlight, super white, 5 LEDs on the light, 120ft effective range, light can be seen 2 miles away. Greatr little light, only about 5 inches (12.7cm) long, one (2.5cm) in diameter. Can rolls a two meteric ton car over it and it'll be ok, as well you can submerse it up to 150ft. The LEDs are good to last 12 straight years of burn time too. Comes with a handy belt loop carrying case too :)

With all these cool LED applications, you'd think they would come up with something better for cars...

I have a miniature LED flashlight in my key chain. One LED only. It's great to have there.
