Can you elaborate on the heat dissipation issues?

  You have to keep the LEDs relatively cool or their lifetime decreases substantially. That's why most LED bulbs of reasonable intensity have a heat sink integrated into their design. In practice, this isn't too much of a problem when you're designing the entire bulb (and perhaps the housing). But it does mean you're still stuck using incandescents as, e.g., oven light bulbs. (I say "stuck" mostly in a design sense - the inefficiency is irrelevant in that application. But LEDs give more shape flexibility. I'm a fan of how they've been deployed in refrigerators to provide more uniform illumination, for example.)
