When to change to CFLs?
I have a home with lots of recessed lights using BR30 bulbs. Last time I was in Home Depot they had a 6 pack of CFL BR30 bulbs for around $15. The prices of the bulbs has come down quite a lot and now I am wondering whether I should swap out my incans for them.
I guess I have a few options but am not sure which is the best route: swap them out when the incan goes out; replace working incans in rooms that I use a lot; replace the whole house. The latter does not seem like the smart route and the first option seems like I could be losing money even though I'd be using the incan bulb till it dies. What would be your guide line or benchmark be for a room to warrant the cost of switching to CFL?
