Help with bulb replacement

[blkdrgn]

What type of bulb is this? I thought the box said PC 15W but when I searched online for PC bulbs it doesn't look this this. One is blue and the other is white. This is a Resun DMS-400 12g tank. Never heard of it? Me neither. This is all they sell in our lfs.

If you look on the power cords of the light fixture (or if you can open it up and look at the parts maybe?) it might say what wattages it takes there. They look sort of like the coralife screw in PC's but those are either 10 or 20 watts, but not 15....
