105 watt in a 100 watt fixture okay?

I want to use two 65k CFLs and one 50k CFL to start

The light bulbs say "Fits into a regular medium screw in base"

so I'm thinking about using this...

First of all, it will fit right?

Second of all is it okay to use a 105 watt CFL in it?

It says: "Use up to a 100 watt incandescent bulb"

Also can I use one of those one-into-three connector things with this?

Well if it says not to use anything above 100 watts i wouldnt do it. A 105w CFL is going to pull just as much watts as a 105 watt incandescent bulb, notice they are both 105 watts haha.
BUT your 105 watt CFL will give out more light then a 105 watt incandescent bulb even though they draw the same amount of power

It's not enough to worry about. You will know for sure it's ok after you run it a few hours and see that the wire doesn't heat up.

You'd have to be over by 50% to even begin to notice a problem.

(but, technically you are exceeding the limit by a tiny bit so it will come down to whether you are paranoid about it or not.)

It might work. Cfl doesn't generate as much heat as a regular bulb does. I currently run a 23w cfl on a 15watt max socket and it runs cooler than the 15 watt bulb. So far no problems. Maybe mines works because theres a fan in there. My dad uses that kind of bulb socket for housing a 150watt halogen for his plants(not weed lol) and its fine so far. But the reflector isnt on it. It's just my experience.
