That's exactly what I do with my lights. Got viparspectra too.
use them for veg ,,,my advice is to then replace them with a 600w HPS. It'll give you time to have the money for the HPS.
Two of those viperspectra leds won't give full coverage in flower
A magnetic ballast ,globe and shade should be well less than two hundred dollars.
But will easily cover itself in the extra yield you'd get
No Billy not enough coverage even with two
