Our setup on a 1/2 dozen nets, net size average are 6 to 8 ft square, mesh most are 1/4 inch,
Pulley set up off the houseboats, depth dropping net is choice mine is 8 ft maybe a little deeper at times,
Net lowered, light is on as bright as it goes, bulb choice are table light bulbs, spot lights outdoor floods, what ever u have will work.
Bulb usually about 6/8 inches off the water in a reflecting hooded light, (13$ walleye world). Tab of caulking where wire goes into plastic housing, We have everything from 60 watt table light bulbs to spot light bulbs the latter takes a little more abuse as the light sometimes gets banged when u dip your bait from the net Opps there goes bulb. I splice in to a dimmer switch, typical switch hardware store 6$ ?.. Been. Awhile,
Shad comes to the light ideally its circling the light, we dim till it's a almost burnish red very dim. This tightens the pattern and draws those deeper shad, standard tech to raise its a hand over hand slow steady pull as u see your net harness start to reach the surface the pull speeds as much as you can.

Nets Memphis net an twine company. 50/ 80$
Frame to many variables mine 20$
Light dimmer, bulbs less than 15$
Outter proof cage and dock neighbors good luck. Hardware cages out of wire most 50$ isn

If you skimp on the cage your wasting your time.

This year I'm 75 yards from a set up that gets nightly cage full pulls. (My pulls are horrible this year all small bait) We live on our boats nightly pulling bait depending on the number of people we take out
