Location: Northwest Chicago Burbs | I might have a semi genius idea about lighting for night fishing. But wondering how long the masses believe 2the deep cycle batteries will run 75 watt bulbs. 2 of them |

Location: WI | 150 watts at 24v is 6.25 amps
Given a 105 ah agm battery should be 16.5 hours. That is to drain batteries to a safe 50% discharge. |

| Slamr, My only question is are they really 75w LED bulbs or are they bulbs that are equivalent to 75w Incandescent bulbs? A LED bulb that draws 75w has to be incredibly bright. I lit my whole 18x22 basement to operating theater brightness with less than 75w worth of LED bulbs (9w dimmable can lights). If they are equivalent to incandescent they pull a lot les than the 6.25 amps mentioned and the specs on the package or instructions will tell you how much they draw.
I personally use a set (4x) of 12w floods to light the deck of the pontoon boat for night walleye fishing and it's more than enough to read by and still see the fish in the water from light coming over the sides. I use the RGB changeable floods with the remote so I can use the Red mode for night fishing. It doesn't kill your night vision like other colors do. To run this system I use a set of 12v 5ah batteries (wired parallel) and they will run for several days of constant use. I think the lights draw .2-.6 Amps each.
LMK if you want to discuss this further, I have used LED lighting in a ton of projects...
HTH,

Location: WI | I was thinking the same thing. I am an electrician and install a lot of led fixtures on exteriors of buildings. The only led fixtures I have installed that are that big are parking lot lights. Those are 90watts and the equivalent of a 400 watt hps. My guess is its a 75 watt equivalent at about 12watts. |
