Does anyone know of any waterproof/submersible light sensor that can be used for measuring exact light intensity and K-scale of light at different spots in the aquarium? I'd like something to measure more precisely how much light reaches the bottom of my tank versus the top, how much more light shines in the middle of the tank than the outer edges, etc. Not really liking the wattage/gallon method of operating with a blunt instrument.
Looked around the net a bit, didn't come across much.
(if you know a store that carries something, even better).
