energy savers unlimited inc ballasts - can't open up?


New member
i have two "energy savers unlimited inc" ballasts. one for the actinics and one for the hallides. they link together. theres a sticker on one box, but nothing on the other.

i was told i could open the other ballast to find out the info etc. however the 4 screws on the bottom do not allow it to come apart. it seems as if there are rivet type screws. anyone have any input on this?

how i can get in the ballast or a better way to find out the model etc.?
