I need to point out that the inside diameter of these bulbs seems to have gotten slightly smaller in more recent purchases. I needed to change one recently and I could not clip it all the way in because it would not clear the ballast like the prior bulb did.

I need to point out that the inside diameter of these bulbs seems to have gotten slightly smaller in more recent purchases.

Unfortunately I tried too hard to make it fit; it cracked then fell out and smashed. $10.00 straight into the garbage! They can now only be mounted by pushing them only part way into the clips which I don't care for even though you have the cable and plastic lens to keep it from doing damage if it pops out. Read Less
