Default Did a test on underwater dock lights

Tested the LED 400 W equivalent LED light against a 400 W metal halide Green Monster light and the results are very different. The LED light attracted some catfish and lots of bait. Next night different story with the Metal halide. Several Snook, Mangrove snapper and tons of bait. Wife says it's because the wavelength of the Halide is much greater than the LED. If the object is to attract game fish it kind of negates the electrical savings I think.

She probably could have told him the outcome and why before he started apparently.

Your wife is correct.
Example. In the saltwater reef aquarium world nothing grows coral better than Metal Halide lighting. LEDs come close but no cigar.
My personal thoughts are that it is due to the wave length as well as the UV radiation that Halides give off as opposed to the LEDs inability to produce said radiation.

Whether fish can see this, I don't know, but corals do phosphoresce more under the Halides.
Just my non scientific observation.

Keep both lights off for a week or so and try the halide light the first night, followed by the LED the second night. My neighbor has a dock light and he turns it on a few nights before he wants to fish it as more and more fish show up each night. When he turns his on, he gets nothing but bait fish the first night. Might just be the light being on for consecutive nights, not the type of light.

Problem we have around here is that these idiots decide to come and fish your lights at 3 or 4 in the morning with no regard that you may be sleeping 30' away. All my neighbors turn them off now as the people started showing up on a nightly basis and were having conversations, dropping things in the boat, knocking around empty beer cans and making all sorts of noise.....along with items starting to disappear off docks.

Wife was a lighting specialist with Grainger for 14 years and then LED project manager for Philips lighting for 9 years and now has her own lighting consulting business. Very smart and a red head. so don't try to tell her anything. Photos coming up

How does a 500W halogen compare?

She says a 500w Halogen underwater would be equivalent to a 100-125w metal halide.

Much difference out of the water? Dock is on somewhat open water, underwater wouldn't last long. Currently running 4x 500w halogens, was considering switching to equivalent leds - didn't give much thought to the type of light, just brightness and power draw.

She says out of the water about the same amount of light projection. The problem with LEDs is they are plenty bright but the wave length and the distance the light will travel is significantly less than conventional lighting. I'm a mechanical guy and even asking her questions will inflict me with way more knowledge than I can absorb but I do know the LED underwater lights attract far fewer fish.

I don't know lighting, but I thought the Green Monsters were 175W mercury vapor?
Where do you find a 400W Green Monster?
