Just for fun, (and because Ive never seen a thread started like this before.)
Lets see a pic of your tank when its dark and quiet in the house.
Here's my 220g, Im running a 18w led tube turned backwards in the fixture. The lighted bar at the top is actually the reflection of light itself. I have the tank lid open so that you can see it for the pic. It looks like a lot of light but actually its not.
