It looks like there are 5 Crouse-Hinds and the other 3 I don't know. The Crouse-Hinds have the fancy little piece on the top and bottom and the backs have grooves or ribs in them. They also have two little latches by the shade that allows them to be opened. Don't know how to explain but 5 of them look alike and the 2 very center of picture are different along with the one on the right hand back.
I agree with T-way on the pricing. I believe the 4 ways that bring the big dollars are one complete 4 way unit. Not separate lights joined together like this. That's my 2 pennies.
