    I bought some 6500k bulbs yesterday to replace my 4100k bulbs. So I measured my previous bulbs that I had, and I got 17 3/4". I went ahead and bought the 18" because I assumed bulbs didn't come in quarter sizes. Well now I'm second guessing myself. Do you think 18" will be too big?

    I think the 18" bulb should be fine

    Think they measured the 18" with pins in.

    Thank y'all! I was thinking the pins would make it 18".
