Yeah i know them as dual spectrum bulbs, there's probably a few companies that make them, hortilux is popping into my head for some reason but that might just be a random thought i had thats got nothing to do with lights at all, i'm pretty baked lol i had one a couple years ago and it did a pretty good job from what i can remember, it's probably better to have seperate bulbs as they're specifically designed for either veg or flower rather than one that can do both but won't be perfect at either.
