Madagascars require good full spectrum light. Mine are under these: https://www.amazon.com/gp/product/B07BPWD1LY/ for over 3 years and they love it. The white / yellow plant lights are useless for these. They need the "fuchsia" full spectrum. Monios has a two foot version on the same page. There are double lamps in the fixture, with a reflector.

The Madagascar will also get stressed (just like pets and people) when moving to a new location. Give it some time under a new light. It will likely drop a few more leaves (curl, tips turn black and fall off), but it will recuperate fully in a month or so.
