If I'm doing heavy duty up to my armpits maintenance on my 55 I just take my fixture off and use a clip on work light with only 13 inches of breadth there just isn't a lot of room to be working around a fixture if I'm replanting or rearranging.
I ditched my glass hoods. I used to have them always seemed to be in the way. I always took them off for maintenance as well. Stepped on one of them once as they are hard to see when laid flat on carpet... They went in the trash after that near miss in bare feet.
Only time I miss them is in the winter when they really cut down on heat loss and evaporation.
TLDR: Get used to giving yourself the room to do the maintenance when it is time to do the big stuff it makes it way easier and more time efficient.
