You need to watch out for the 2 different sizes of metal bulb clips. Not sure if this may pertain to the 96watt bulbs but it's worth a try.
I had a Coralife 65watt enclosed unit with the sliding plexiglass protector that took the regular PC
bulbs. Now I have a JBJ retro kit 65watt and the 2 PC
light clamps that came with it are too small for my bulbs from the Coralife unit. Their width is shorter.
New bulbs are on the way. If I need to, I will get some wider clips.
What I'm getting at is be sure the lamps fit into the clips smoothly. You shouldn't have to force them. I've heard this is what causes some bulbs to break at the end where the 2 are fused together.
Just my $0.02 worth.
