You need a light meter.

If you don't have one, start with a free lux meter app for your smartphone. It uses the camera's light sensor to compute a regular lux reading. I would also order an "LX-1010B" (or similar) handheld lux meter. Less than $15, better readings, safer to use around saltwater than your phone!

Surface measurements around or over 30,000 lux should be fine.
