About the only reason to replace one is if the manufacturer used a proprietary bulb that is no longer available, and altering it to use a different bulb isn't possible. The home processing of color photography in Czechoslovakia was possible since 50ties. For older Opemus enlargers (as Opemus 6x6, Opemus II, Opemus III) was produced special adapter, called Meocolor. Meocolor was inserted between bulb and condensor.
At the top of adapter was inserted IR filter, color filters were inserted into the slot. Subtractive filters were from glass and coloured gelatine in sets with 12 pcs for cyan, magenta and yellow color. With this filters you could change every color with 5% increments. The filters was made by Agfa, ORWO and by Meopta (Subtracolor correction filters). The first color head produced by Meopta was Meochrom and was produced for Opemus 5 enlarger.

This was very cheap, you could insert filter between lens and paper, but now is this method obsolete.
