What does the bulb look like? I bought a brand new one today at the LFS. The information on the end has flaked off and I am wondering if it is used, or even if it is the right bulb. I put it in just to see, and it looks very yellow for a 10K. I have another one that doesn't look like this one. This one is long and has a bulge in the middle. Not sure how else to describe it, but if you have a bulb like this you will know what I mean. What bulb is this?
