Looking to replace a rated 15 watt bulb with a different color temperature, read below....

The only bulb I was able to find with the color temperature that I wanted was a fluorescent energy saver type 40 watt replacement that only uses 7 watts. I still should be able to use it in my application right? And why?

I read your question a few times, hesitating before I realized "it's just a light and as long as it fits into the fixture, gives you the light you are looking for, it should be OK." On second thought - the techie in me wants to know what the application is you have there, before I could answer the "why".
So would you tell us? Thanks.

Its just for a 10 gallon fish tank. There are two of the tubular type fluorescent bulbs, each using only 7 watts of power apparently. But they are supposed to go into a 40 watt replacement application? On the cover of my fish tank it just says to use a 15 watt max. So my guess is that if I'm under 15 watts, then i should be fine.

Is this case your are good. The 15 watt limit on the tank is there because they don't want to have the bulbs in there to create more than 15 watts of heat. In other words - anything higher would warm up the water in the tank.
The two 7 watt fluorescent lights are below that limit and as long as they fit into the fixture securely and create the color temp you want, you are all set.
The "40 Watt Replacement" comment on the packaging of the fluorescent means that a 7Watt fluorescent bulb creates as much light as a 40Watt incandescent bulb. Therefore - you might be OK with just one of the 7Watt fluorescents. Do you remember how "bright" the old bulb was? You don't want to "blind" the fish...

This new color temperature seems to be better actually not too bright but a lot brighter than the soft white incandescent bulb. Thanks for the help!
