TCP 1G2504 - 4 Watt G25 Compact Fluorescent Globe Light Bulb, 2700K

Bought several of these to replace convenient bulbs and absolutely love them. They are just as bright, come on instantly and have cut down on the amount of heat generated by the convenient bulbs by 75%. Hopefully will save just as much on my electricity bill.

For the price I don't think these bulbs last long enough, but can't find the 25 watt equivalent G25 Globe lights anywhere else, only 40 and 60 watt.

Update:
These bulbs just don't last. An article in the New York Times on compact fluorescent bulbs stated "if the bulb is enclosed in some manner, the additional heat will shorten the life of the bulb."

Will now replace the bathroom light fixtures with a fluorescent tube to get away from this type of bulb.

We read the reviews and got one globe to see how bright it actually was and whether it lasted or not. It won on both counts so we ordered 8 more and replaced both bathrooms' incandescent globes. Like any cfl they take a few moments to completely light up to full brightness, but we didn't see that as a problem. However after only ten months, two out of eight bulbs have failed, so there is little or no cost savings. As these CFLs wear out we'll go back to incandescents, as more cost effective.
