The lens dia it actually about 1-1/2ish. They are a knock off (yes another one) of my stuff so I ain't tellin you who's they are.

I make a similar one called the Micro B. but I don't do flames, only clean and smooth. You can get them in 35w just like the big ones, BUT they are not as sturdy as the larger 2 1/4" ones. I also do make one that is exactly 1" lens diameter but it's only an LED taillight.
If you have any questions, lemme know.
