you could use it as supplemental lighting but you'd have to have a shitload of these to make a good grow, and you'd have way too much heat, even more than regular hps bulbs. Also, while the electricity cycles, the light does not - once the gas ignites it's on, only at first it might flicker during "warmup" to it's proper operating temp. When it's cold, you'll get more flicker because it takes longer for the bulbs to "fire" up. And while your strobe theory is good, it will only work as supplemental light- if you read about extending veg times for outdoor growing, they will string incandescents above the plants, run them for 12 hours, then sometime within the next 12 it has to have 1 more hour of light - not in a strobe effect, but solid light. I think the plants would have a hard time adjusting to that type of lighting, but hey, always willing to learn!
