Hey Mate,
before I would go for a CFL I´d rather have a decent look for LED. A TS600 from Mars Hydro, price is below €100 in my area. You´ll get a stable light with a good spectrum. Vipar Spectra, Spider-Farmer, Horticultural Lighting group...
There are tons of producers at the moment. May you want to have a look at the Light-section here at GrowDiaries.
You´ll find one, for sure.
Best of luck for the rest of the way!
Servus,
Oim.👍
