We're not entirely sure why it took so long to do this (we here at Engadget would look forward to a future where all
articifial light is LED or fiber-based), but an Arizona-based company named Enlux clustered un-housed LEDs on a
head-spreading circuit board (matched also with aluminum fins) to make LED-based floodlights. The geek-over-practical
quotient is pretty out of control though: while each bulb lasts 50,000 hours (used 8 hours a day that's 17 years) and
uses less than half the wattage of similarly bright incadescent bulbs, each Enlux flood will set you back $80 bones.
Yes, that's eighty dollars.
