I think I saw them in person at the RI Orchid Society show a couple months back. They were really small! I didn't have the time or chance to ask the person who had them about his experiences. I had seen photos before (advertising) so their small size really surprised me. I should have delved into it...now you've got me all curious! Incidentally though, I've been trying to find the person's email address regarding another matter so if I turn it up, I shall ask him about the lights.
