There are extremely high powered LEDs out there, and most of the ‘creative’ uses of these are extremely high-powered flashlights, complete with heatsinks, forced air cooling, and beefy power supplies.

In high-power lighting, needs are emerging for LED luminaires rated to 100, 200 or even 600 watts (over 60,000 lumens), to cover wide areas. The higher-power heat sinks increase in size and weight ...
