Hello,

Offline, switch-mode LED drivers that exist *inside* 4 foot LED light tubes, suffer heat, and therefore cannot use electrolytic capacitors...........

-therefore, small-Faradic-value value film and ceramic caps have to be used at the input and output....

..this makes feedback compensation and stability very challenging.....what is usually done to mitigate this?
