    I'm with derek on this one, check the spec sheets on the edison opto or the osram platinum dragon LED's. They're getting there. And the optics will be better as well, the smaller the light source.

    I would also like to mention how happy it makes me that this appears right above the fire that derek, errrr someone started


    I have 2 of those little color changing colorkinetic led changing bulbs, they're nice, not bright, but still pretty cool

    Only a matter of time until they are powerful enough!

    Its all about heat management. Unlike incandescent, where waste heat is found in the beam, LEDs need to have the heat moved out by direct contact (think heatsink) as it does not exit in the beam. Also, their performance plummets as the junction temperature rises. So, it's all about pumping up the power while keeping things cool.

    Hummmmm... I'm picturing an S4 with a plug and water hoses ;)

    Definitly likely within the next 5 to 8 years considering how fast LED technology (esp white) is moving along. Just look at how many high output LED flashlights are available now. In most typical cases now, High brightness White LEDs traipse both incandescents and fluorescents in lumens per watt and lumen efficiency/ life time.

    Its not only that LEDs are more efficient than incandescent, its that a red LED puts out 100% red, as compared to having a deep red gel on it that may absorb 99% of the output.

    One little clarification- (Although most of you already know this.)
    The reason the plastic casings for LEDs are dyed different colors is simply to identify the color the junction inside emits. It does not play a role in the output color as they are monochromatic to begin with. Many high output LEDs come in a clear casing, as do multi-junction / multi-color units.

    Actually, most High output LEDs do not die the casings any colors since the domed lens on the LED is either polycarbonate or Silicone. The only way to distinguish colors is to know them by how the die looks or by just turning them on. Most of the newer fixtures you see on the market these days are using high output (luxeon K2, Osram dragon, Seoul Semi conductor, cree XRE ... etc) that operate similar to the older 5mm LEDs but have a much more even and bright output and usually have better color characteristics
