Look for lights with photometric reports which show high values in the blue (400-500 nm) and red (600-700 nm) parts of the light spectrum. That's what plants crave. These can be all over the map in terms of price, but if you want it to be nice in living spaces, aim for something with a neutral-to-warm temperature and relatively high CRI. Your price point will increase, but these lights last a long, long time and make a substantial positive difference in my opinion.
