No that was WAY too high. There was more light in the room than the tank

I also went through the entire RC thread about the lumenbrights and mostly everyone found to get the best PAR and decent spread, 12" to the bottom of the reflector worked well (makes the bulb about 18" off the water). I know that article said 20" or so but as most people found in that thread, 20" was too high.
