Don't believe the hype.

LED is nowhere near a mature technology yet. LEDs may look cool in your computer case and give a brighter light than those tiny incandescent flashlight bulbs, but trying to replace big gas discharge bulbs with LEDs is just insanity.

1. LEDs need LOTS of heatsinking. Their l/W output is terrible, and unlike an incandescent, halogen or gas discharge bulb, the heat can't be thrown out the front, it HAS to be heatsinked.

2. LEDs are tiny, tiny sources of light - they will cause lots of glare if not used with diffusers. Whereas gas discharge bulbs don't suffer with diffusers.

3. They're too expensive, and the fancy "More than 100 lumens per watt" are invariably tiny LEDs running at less than 1 watt.

4. The parking garage bulbs are not incandescent - they are already high-efficiency mercury vapor/metal halide or very high-efficiency high pressure sodium or ultra-high efficiency low pressure sodium.

So in conclusion, don't believe the hype.

Let's face it, Apple ripped off the basic touchscreen concept from basically everyone else on the market and called it their own.
