AFCI breaker constantly trips

We have a lot of CFL's
Most of them we have switched to CFL Daylight bulbs
These are actually a different "color" then normal CFLs'
They are a brighter light, not yellow

We have (2) 13w CFL Daylights in the main room & we like them better then the overhead light that has 2 60w reg bulbs

Man up and get this fixed before you kill your family
Whether it's tripping on arc-fault or overcurrent, the CB is tripping for a reason. Call a qualified electrician to have it resolved. It might be something as simple as a minor overload of the circuit, but if there's an arcing issue the few bucks spent to pinpoint it could be the difference between peace of mind and a potential fire hazard.

Tuckahoe,

Just curious, given the information in the first post, how would you go about troubleshooting this problem if you were called out on a service call?

First, determine what I'm dealing with. The CB doesn't immediately trip, therefore it's not a fault to ground. So is the circuit overloaded or is it tripping on arc-fault? The OP said it trips 'almost on a daily basis'. I'd get everything turned on the circuit and amp it. It's a 15 amp circuit and it normally shouldn't be loaded to more than 80 % (12 amps). If it's reaching 13 or 14 amps the breaker could be gradually building up heat until it eventually thermally trips. In that case, the ambient air temperature around the breaker could also be a deciding factor in how quickly that heat is dissipated and how quickly the CB trips. Anyway, if this turned out to be the problem, I would suggest splitting the circuit by pulling a new one to reduce the load.
If overcurrent was not the problem but it was instead tripping on arc-fault, I would find out if any brushed motors (vacuum, fan, etc.) are being plugged (or hard wired) into the circuit. The arcing from motor brushes can cause some older arc-fault CBs to trip. If this is not the problem, start checking devices on the circuit (particularly switches, as someone else noted) and see if operating them duplicates the problem. Check the terminations on the devices for tightness. No more than switches cost, and probably no more than you would be dealing with, it could be worthwhile to change them out; particularly if the quality of the switches is questionable. Just troubleshoot through the process of elimination.
