Check what the wattage is that they consume, then tell us how many lumens they output. Some CFL's, especially the dollar store ones, are much less efficient then good ones. A good CFL would be a 23W that produces 1600 lumens. My friend bought a few from the dollar store because he saw them and thought he was getting a good deal. They consume 30W and produce 1500 lumens......you get what you pay for.
So check the packaging, and tell us whats up.
