want to add more lights. electrical questions

Here's a question to the electricians. Currently I'm running 2 1000w Metal halides with the convertible ballasts for HPS. This setup is on a large closet in the garage. I had to run one one extension cord for a short distance into another circuit because I quickly found out that 1 circuit couldn't handle it.
Now I want to run 3, preferably 4 lights in a bedroom instead of in that closet. The bedroom circuit is 15 amps, and the circuit actually goes to 2 bedrooms adjacent to each other, so I can't just run a cord underneath the house and into the other room. Above the hallway ceiling in the attic is an electrical circuit that goes to the 2 hallway lights and 2 small bathrooms. Can I tie an outlet into that for the second light?
I'm gonna go back up there and hopefully find the circuit that goes to the master bedroom. If that is easily accessible, hopefully above the hallway in the attic, I'd like to put an outlet into that also for a 3rd light. Further research required for the 4th light.
My breaker box does not have any vacant spaces. Thanks for your input.

can you get wires from the breaker box to the attic?
you can get split breakers that will have 2 breakers in it but only take up 1 spot in the breaker box.

max. wattage at 80% load
15 amp is 1440 watts
20 amp is 1920 watts

if i was going to use that amount of lights and other equipment that will be needed, i personnally would do a small sub-panel in the attic. but i can do all that myself though.

Thanks for the response. I think i'll look into that. Maybe I'll call an electrician..

i would agree with the previous post about the sub panel.
you are getting pretty agressive with the lights so safety
must be a concern. I would first ID and label all breakers in the existing
panel.
with some luck you may be able to double up and free up two spaces
and then run a 220 circuit to a sub panel. Another option is to place the sub panel
and divert existing circuits. becareful and good luck

i recomend that you come off from your breaker box with a 220 volt line to the adict. most ballast are switcabaletorun 110, 220, 277, or 440 volts. run all the light on 220 volt and you want have any problems.
