Cleaning the aquarium for the first time in half a year

There is no material today and it is a miscellaneous note.
It’s been about a year since I bought an LED light for an aquarium.
Until now, I used fluorescent lamps and the aquatic plants grew well.
When I changed to LED, moss grew well.
A film like seaweed is applied to cover the inside of the aquarium.
You can get it right away by rubbing it, but I wonder if you can’t go for a cheap LED
Is the fluorescent lamp for the aquarium more expensive, so is there a countermeasure?
Nowadays I want to put it back, but the replacement light bulb is expensive …
