They say that they're equivalent to a 60W light bulb, but if its only using 15W, it should work fine in a fixture designed for a 40W bulb...correct? I just want to make sure.

Yes. It will save electric costs, last much longer, and produce close to the same amount of illumination. However, they take a minute or so to produce full brightness, and are less bright and take awhile to brighten in cold temperatures. They also CANNOT be used with light dimmer controls. Aside from these minor disadvantages, I highly recommend them, especially where the light will remain on for a period of time.

What do you mean, “a fixture designed for a 40W bulb”.
You mean a light bulb socket which is ‘supposed’ to have a 40 watt bulb in it?
The wattage drawn by the bulb is dependent on the light bulb, not the socket. The bulb has some internal resistance built into it by virtue of its filament (assuming incandescent bulb). When you plug it into the socket, a standard AC voltage is applied over it and it will draw current according to Ohm’s Law: V = R * I. The socket you plug the bulb into merely allows fro the electrical connection and holds the bulb in place.
Unless you mean that the fixture is only designed for a 40 watt bulb for other reason (like the heat generated / wasted by the bulb), but those newer, energy saver, fluorescent bulbs waste much less heat, so this shouldn’t be a problem.
Or perhaps you have some circuit breaker or other electrical element wired up with that socket which is only designed to take 40 watts max, in that case, I would not exceed this value.
People generally misuse the term ‘watts’ / wattage when it comes to light bulbs. The wattage of a bulb measures how much electrical power it draws when you turn it on, it is not a measure of brightness, per se. Over the years, people have associated wattage with brightness…and not without reasons….a 100 watt bulb draws more power and gives off more light energy than a 60 watt bulb, for example.
When you see on the package that the 15 watt energy saver bulb compares to a 60 watt incandescent bulb, it is just trying to provide an easy way for you to compare the brightness of the light it will emit. Although it will draw only 15 watts of power, it will emit the same amount of light (so the package claims) as a 60 watt incandescent light bulb. So if you normally had a 40 watt bulb in that socket, you will be getting 20 extra watts’ worth of light (<-- see how I just misused the term)…the proper unit would be Candelas (for light intensity).
So, long story short, the new 15 watt bulb should work fine and could even give off more light than the old bulb, but take less energy to run.

I've save quite a bit of money. I would usually change the bulbs out in the bathroom (6 bulbs on mirror) several times a year. Since I switched to the new energy efficient bulbs, I haven't needed to replace them yet. As goes for the other bulbs in the house, they are still shining bright.

15w Light Bulb

Should work fine as long as the voltage is the same! The 60 Watt equivalent means the bulb will put out the same amount of light as a 60 Watt standard bulb. You will see that your room is brighter and your electric bill smaller.

Yes. The wattage rating on a socket is a maximum. So any bulb that requires less than 40 W is okay. Keep in mind that compact fluorescents do not perform as well in cold environments. So try not to put them outside or by air conditioning vents.

That fixture is designed for a 40W MAX. It is always o.k. to used a bulb less then the max rating (even if it is a compact florescent.)

Hi. Yes. The bulb will only draw the 15W and will be cooler.

Go by the wattage rating. As long as you're not using a bulb that's rated for more wattage than the lamp is designed for, you're fine. In the scenario you give, no problem.
