I suggest going to Wal-Mart and getting two mini Spiral CFL Daylight bulbs
They'll be a little bright, if you want something slightly duller you can go to Lowes or Home Depot and their Daylight bulbs only go up to 5,000K instead of 6,500K like Wal-Mart's does. I assume you have the screw in types since you said you have two bulbs.
The bulbs at Wal-Mart come in a pack of 3 Mini Spirals and only for 2.88 or something like that. This is the packaging you're looking for:
And on the back most, not all unfortunately, have the Kelvin rating scale. 2000K is that yucky orange/yellow color (Warm) that living rooms have and stuff, so that's the one you don't want. Do not get "Soft White" or "Warm White" those are the low Kelvin Ratings. Here's a picture of the Daylight 6,500K bulb:
