I use something similar to that CFL light bar you got there Vostok. Great for starting sprouts or cuttings in the bedroom closet. Even vegging plants to a decent size before going under bigger lights.
Those same plants are now vegging under my old 8 - tube bank of T-12 fluoros as my HID grow lights are at a buddies for another month until his plants are done. They look like crap atm as I was away for 6 weeks since the first pic and just repotted into those 2gal pots. The wife isn't the best plant tender but she kept them alive until I got back!
4 are my experimental try at making my own autos and two are a very high CBD strain known as Otto#1. All are about to be cloned then those will get flowered out once I get my gear back.
Here's a pic of my homemade veg tent with the light panel installed but not completed. Built hat panel 15 years ago and haven't used it in a dozen years. Pays to hang on to stuff I keep telling the wife!
The tent is just 2x2s and I used hinges so the walls fold in so I could get it downstairs. Barely makes it and now I'm using it upstairs in the spare bedroom. 8x4 tent is going downstairs when buddy is done to hook up with my regular grow room and it will be used strictly for flowering with a 1000W EYE Hortilux hanging off a 6' light rail to do the whole tent. Perpetual grow gonna happen finally!
I've since added another ballast and 2 more tubes to make it 8. Each pair has a disconnect so I can run 2, 4, 6 or all 8. Total of around 25,000 lumens using Daylight Ultra 40W tubes that are hard to get these days.
