Product reviews for LED-7501 - 60° flood beam

Pros - I installed 6 of these lights mounted mid-cab (fenders) on a 7 series row crop tractor.  With the brightness, I would not go below 60 degrees. I also purchased two 40 degree lights for the front of the cab, but they tend to have too much spotlight.  60 degrees work perfect for all mid-cab lights.  The 40 degree lights would technically work on top of the cab, but they are too bright in that location as they give too much light deflection into the cab from bugs and dust.
Cons - There are not ANY labels on these lights, so it will be impossible to replace them in the future (unless I can remember exactly what I ordered and where I placed them). Given that I have two 40's and four 60's,...AND THEY LOOK EXACTLY THE SAME, I was hoping some sort of label would be included on the lights.  Other Larsen light are properly marked with Product ID, so not sure why these aren't.
