I don't think there will be a problem, just try not to leave them too close to your plant.
Although I think it would be more beneficial in the flowering stage when there are places that the light doesn't reach.
Hi mate, I believe as long as they are both dimmed down to suit the size of your plant it should be a better light. But the XS1500 should be enough, its a better light than the burple one. good luck and happy growing
