With the tighter frequency of an LED, which is better for reflecting color (green vegetation, as well as planters with flowers), 2,700 or 3,000? Also, dark green tropicals that are not translucent are like black holes. In many applications they look great with green light on them. Anyone developing a green LED MR 16 or PAR (not with a green lens)? It would be so awesome if fixed colors were available.
