If you still want to go the LED route, possibly the instructor in the shop class (if your school has one) could cut a piece of translucent plexiglass for you to mount at the base of the lamp housing, or rest on top of the condensers. May help with the hot spots.

Especially if these are students learning for the first time. More seasoned printers would probably apply more scrutiny.
