What size lights are these?
 

I'm wondering if anyone can tell me what size lights are pictured here - https://www.quadratec.com/products/12249_764X_PG.htm

I just bought the updated version of this rack (in the mail now) and am looking to purchase the right sized lights for it. I like the look of these but am having trouble estimating their size.

Any and all educated guesses are welcome!

Those look like 7" lights. Wattage unknown

the look like 9" to me

I think 9", too, but have you called JCR?

Also, you can get it cheaper directly from them. $80 cheaper for the powdercoated version.
