Which LED light bulbs do I want in my bathroom?

My bathroom has six light bulbs in it and, to my shame, they're incandescents. I'd like to replace them with LEDs so I never have to think about them again. Which LED bulbs are most like your standard 60W incandescents? [more inside]

Why do LED lightbulbs have a bulb?

While changing a bulb in one of our rooms, replacing a LED with a CFL because of a need for brighter lighting in this work area, it suddenly hit me: Why does an LED light have a bulb? In both incandescent and CFLs, the bulbs trap gas (or vacuum as the case may be.) But why an LED? It doesn't use a gas and it doesn't need to operate in a near-vacuum for efficiency. Closer examination showed that the bulb was plastic and had no lensing effect. This question is almost answered here. Because of the question regarding heat sinks (which seem much reduced in modern LED lights, I'm guessing the answer is because they get hot. So I'm guessing that's what it is, though I also think that having a bulb makes it easier to screw into the socket. Taking these points together, I can imagine getting a burn if there was not bulb by brushing up agains an LED stalk that was on until a few seconds ago when you decided to unscrew it. So...have I answered my own question or is there more behind the bulb?

Can I use a CFL or LED bulb in an outside flood light type fixture that is hooked up to an in-wall Intermatic timer? I was told no but I would like to confirm. If that is the case, I'd love a short explanation in plain English. I tried Googling but I'm still confused. [more inside]
