When I was running CFL and Flouro lamps ( T5 4/8 bulb ) ... I find them miles ahead than throwing young seedlings under harsher blurple .
You can keep flouro / cfl hella close without issue. The kelvin spectrum of the cfls run from 5000 k ( ecosmart ) to 6400k / 6500k for good early growth and lessen the stretch. But if you have some stretch, it can be remedied with a transplant ( up potting ) and burying the excess stem.
Not familiar with Bestva ( but looks similar to various ones on amazon ). Blue spec tempers excess stretch . But from previous experience with vipar ( back in my early grows ) it is better to “ harden “ the young cuttings, seedlings and new sprouts with a milder light such as cfl or flouro lamps. This way they can concentrate on throwing roots comfortably instead of being overwhelmed by a harsher light. People still throw shade on these kind of lights but they are quite useful when done right.
I like my girls stress free right from the start.

ya bro, thats a flowering spectrum
2700k is straight flowering #s
you want 5000k or higher for vegging plants. mine are 6500k and so are my t5 bulbs.
2700k will still grow a plant, but it will prob be a little stretchy with all that red....you want the other end of the spectrum...the COOL WHITE side....5000k+
Would 40 watt 5000k work? That's my only option if i want to go get them right now.

Yes they would work for seedlings.
Higher the kelvin the more blue, vegging plants love blue light apparently . So we want high kelvin numbers when veg, lower k in flower
3000k is a good flowering spectrum
5000k + is good for veg
3500 and 4100k have been proven to be good all around, start to finish spectrums.

those have UV
yes they work well that is why as seedlings like "some" UV
they are phasing that type out here
they are handy to have around for cheap veg to small seedling light.

Yes they will work perfectly fine
