For 60W equivalent this can happen by natural air flow around the bulb, but a 200W equivalent bulb would need something like a built-in fan
From the net I find that a typical 60W incandescent is 10% efficient, therefore generates 54W of heat within the light fitting. A typical 60W equivalent LED bulb draws 7.5W and is 90% efficient, therefore generates 0.75W of heat in the fitting. Therefore, for an LED bulb to generate as much heat as a 60W incandescent, it would generate 54⁄0.75 = 72 times as much light, and be equivalent to 72*60 = 4320W of incandescent lighting.
Since 60W incandescents do not need fan cooling (or even 150W, which I have used at home in the past), why would a high-powered LED bulb?
LED bulbs aren’t made of tungsten and so cannot heat up to 3000+ degrees without taking damage. LED’s are much more sensitive to heat and will burn out very quickly if not properly cooled.

Where are you getting this number? As far as I know, the most efficient LEDs today are around 50% efficient.
Oh, somewhere on Google.
