When should I buy LED light bulbs?

Dimmable LED light bulbs seem more economical than halogens. But they're really expensive. Will they quickly come down in price, so I should wait? Or will they come down slowly, so I might as well start saving? Also, how good is the dimming? I tried dimmable CFL's, but they don't seem to dim past 50%.

Where can I get CFLs that aren't orange or blue, but just white?

I'm apparently part of the minority that really dislikes warm colored light. I used daylight incandescent bulbs back in the day, and I'm looking for an equivalent CFL. All I've been able to find are either pink/orange (supplied by the apartment) or blue (the GE bulbs at the grocery store). Isn't there a good, just, white? Like the tubes in an office building?

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?

Broken CFL in 2-year-old's room

Okay, need some help regarding a broken CFL (compact fluorescent lamp) in my 2-year-old son's room. I've looked through a couple of similar questions here, but this situation is a little different so I'm hoping for more specific insight. I've also already seen a lot of varying information relating to proper clean-up procedures, potential long-term contamination and adverse health effects, etc. I really need to know what I should be concerned about with regard to my son's health.

Flickering Lights

I had 4 compact fluorescent bulbs (candelabra base) in a ceiling fan that I recently installed and they would flicker terribly until I replaced one with an incandescent bulb and it stopped. The fan is not on a dimmer switch. Any ideas on what is causing this and does it need to be fixed? [more inside]

A dim question.

Let's say there are two identical light fixtures, on two identical dimmer switches. One fixture has two 15W dimmer-compatible compact fluorescent lights, the other has two standard 60W incandescent bulbs. The dimmer switches are turned just beyond the "off" position to the "dimmest" position (identical on both dimmers). What will the difference in power utilization be between the two fixtures?

Sources for *small* dimmable Compact Fluorescents in Vancouver, BC?

I have been switching over to CFL bulbs, but have many lights on dimmers.
