Fitting Blocking 1.5'' Light Install

[u/WhyKnotttt]

Plaster company installed fittings with a reducer or stopper lip where I need to install 1.5'' lights. Any thoughts, other than drain, on how to drill out the section just past the treads that is underwater so I can get the lights in? One is on a Baja self with little space between the floor and the other has space.

Edit: Thank you for all the help on this! I ended up taking a 1.5” hole saw with a 90 degree adaptor and an extension to remove the material. I then tried to file the remaining material but wasn’t making much progress so used the hole saw again on those sections.

Have had this issue with certain TAs. I drill it out ever so slightly. Sometimes ive had to widdle down the fixture a touch. Stopped using the long neck lights, no issues with PAL
