I would pay a little extra and use the 130V lamps.

Also if a dimmer is installed, when lamps are dimmed 10%, the life of the lamp is usually doubled.

If I was not going to dim them, the way to go is compact flourescent. Instead of 65W, you would only be using 15W, and most CFL's are rated for 10000 hours (about 5 times as long as a namebrand BR or PAR lamp)

Personally, I prefer this lamp in the link over any of the big name manufacturers because of size (same as BR30) and its colour is virtually identical to an incandescant lamp, not to mention it is affordable.
