Bulb cracked immediately. Bad bulb or wrong lamp type combination?

Today I was really excited to upgrade my bulb to a 250W CFL... immediately after screwing it in and turning it on however, it quickly flickered and went dark, as a burnt out bulb does. On closer inspection some of the white poweder inside was burned away or something, and the glass was transparent. A small crack is visible at the base of the glass. My lamp is for "self-ballasted bulbs", and it has a 300W max, while my bulb is 250W and does not have pins at the base of the bulb. Does it sound like this was the fault of my bulb? My boyfriend just told me he noticed some random transparent spots on the bulb even before we plugged it in.

Did you get it wet? Ask the seller for a refund?

Nope, it was dry when I put it in. Is it not a problem with the "self-ballasted" part then? That was the only thing I was unsure about, but my bulb base doesn't have any prongs and it's an E39 mogul just like the lamp socket. I can post pics if my explanation is inconclusive.

Did you tighten it by the base or the top of the glass?

I tightened it by the ballast. Maybe I wasn't as careful with it as I should have been before screwing it in, though I can't remember. Sending the seller a refund request and hoping for the best...
