Overdriving lights.
Reefmaster,
10% loss is due to particulate matter in the water and diffraction loss at the interface between water and air. The 1/distance relation is already taken account with the light meter (the measurements were done in air).
Steve,
Looks really good. I don't know how accurate your light meter is...but it seems that you can generate more light as you overdrive (lumens/watt or lux/watt). But...it sort of makes sense....
Have fun with your new lights [img]images/smiles/icon_smile.gif[/img]
Hmm...maybe I should get one of those meters.
