big factor being missed or not mention is the advantages of LED's, like working life on the lights HPs or Sodium to LED's average on HP's & Sodium approx 5,000 hrs LED's 50,000 hrs, power consumption on HP's or Sodium quite high, LED's quite low, optical efficiency on HP's & Sodium are low, optical efficency on LED's high, color temperature on HP's & Sodium is low amber/yellow & uncomfortable, (some even get headaches fishing with these lights) LED's color temperature is quite comfortable cool or warm light available. Light pollution (is excessive, misdirected, or obtrusive artificial light), HP's & Sodium is high with LED's you have very little to none. Shock poof, HP's & Sodium high, glass will break easy, LED's no so much.
Heating, HP's & Sodium are Hot, LED's cool about 65 degrees, maintance cost on HP's & Sodium high, LED's low cost.
its easy to post poor evaluation on LED's and not give the pro's to them.......I listed some of the advantages of LED's I have to say you did mention the comparison price HP's vs LED's yes they are more in cost, but if you see what adavantage LED's have over HP's & Sodium Lights, no comparison. I fished on both HP's & Sodium and had headeaches the whole night, Lighting on boats are personal preference, you love LED's or you hate them, I'm a fan of LED's for all the reasons I listed about them. I've seen many boat I fished on or with that switch from HP's, Sodium to LED's for all the reasons I listed, then again like I mention you love them or hate them, their is NO in between.
I have 2 40W Floods up front 3 27W Floods on each side. My lights are Custom Fitz LED's. I have 2 31 series deep cells (1 for lights 1 for troller) 2 55amp powermax converters (1 for the lights 1 for the troller) I run a 2500W inverter genny withj 2200W working @ (60db's) pretty dang quiet. I get 3hrs running off battery when light start to dim. I'm out on the water fishing 1 1/2hrs before sunset. Our lake close their gates @ 10

m dark 30 is 8:00pm. Now the reason I run a genny with LED's is I fish from a 14-48 jon boat, my 31 series batt's are 59lbs ea, yes I can run a few more but I'll be adding more weight to my small boat were I run a 2500W Inverter Genny @ 69lbs @ 60db's. So its better for me to run a 1 large batt with converter & small high out put inverter genny. The nice advantage of LED's too are running total quiet off batteries only, or with converter & genny. Another is running more lights do to the low amp draw also. JMO
