are these still made today? (or atleast the fixture design?)

i think so, i have bought one 5 years ago for my house , its exactly the same

Progress Lighting has the same style in their catalogs. Trio or quad lamps. For some weird reason the quint lamps aren't made anymore.

Can you use lamps higher than 25W in these? I know it says 25W max but man that seems dim. i like LOTS of light lol. I'm not a fan of using candelebra lamps anyways. they're for nightlights IMO. Do they make this fixture in medium base?

for many years we had either 25, or 40W even 60W in these, the ones with the plastic sockets now have issues

It's best to follow the label's specs especially if sockets are plastic. A good way to cheat the label is energy saver halogens if enclosed. Like a 40w max can use a 60w equivalent halogen. CFLs are weird. The higher their wattage. The bigger they get. A 55w CFL is much bigger than a 60w incandescent lamp. (Will get a comparison pic of both tomorrow.)
