It's mounted on tree fern, in an area that is rather bright but only the back of the mount faces the brightest area...did I explain that right?
It was also furthest away from the 52 degree heater all winter and got watered probably twice a week for the past few months.
About a week ago, I put it in my large tank rather near the top and the blooms are bursting open!
I've never measured the light in there so I have absolutely no clue is the answer to whoever asks
