Light fixture and maximum Wattage ?

Hey, I have a rubbermaid growbox and have 2 5 socket light fixtures in there to hold my 10 27w cfls. Now, the question is, the light fixtures say the maximum is 60watts per socket. I'm using 27w cfls equivalent to 100w incandescent bulbs. Am I well under with 27watters or am I well over with ~100watters? And if I am well under with 27watter, I could possibly go with the 42watt monsters then right? Or would that be pushing it? The bulbs I have in there now are doing fine but I wanted to make sure I wasn't going to burn my place down by using maybe more wattage then I should be. Here's a pic to see what what it looks like:

Well, thanks for the responses. MMMMMM Weeeeeeeeeeeeeed. :rastasmoke:

Watts are the amount of energy any bulb uses. So the 60 watts per socket maximum is the maximum amount of energy that can be used to power the light. A CFL may say it's equivalent to a 100 watt bulb, but for the socket, all the matters is that it pulls 27 watts of energy. In other words, you're fine.

I thought so, so now its time to try and find some more powerful bulbs muhahaha.

Thanks for the response.
