I bought about 15 LED clusters and have installed about half already in my boat. <BR> <BR>I have an 04 Mastercraft, with the stock LED lights in the gunnel's. I disconnected the white light LEDs that came with the boat, and connected to that wire to power the clusters that I have installed. <BR> <BR>My concern is that the wire that is stock on the boat is fairly small, probably 18 gauge or something like that. <BR> <BR>I know LEDs pull very little power, but is it worth running a new power feed from the switch all the way around the boat. <BR> <BR>That would suck. <BR> <BR>Is there any chance that a smaller wire will have enough loss that the LEDs would dim slightly? <BR> <BR>I ask because I am going to add the other five or six clusters this week and dont want issues. <BR> <BR>Thoughts? <BR> <BR>By the way, as crazy as it seems, purple LED clusters are awesome looking at night. Pretty much looks like a black light.

I think you would be fine with what you have.

Hey Rob, <BR> <BR>You would probably be fine with even 22gauge wire. They pull hardly any power, and led's dont dim, they are simply on or off.

i don't now anything about LEDs but is your profile pic taken with a fish eye lens? it looks awesome!

Cool, thanks everyone. I will roll with what I have then. <BR> <BR>Matt, yes it was a fish eye lens. Kind of funny, I didnt even remember having a profile pic. Thanks.

this thread needs a pix... <BR> <BR><img src="http://www.wakeworld.com/MB/Discus/messages/65921/332462.jpg" alt="Upload">

I think Grant said these pull something like 7 amps.

Mike: Im its more like 3 amp' I tested with a meter before I finished my install and it was around 2 amp's and then I threw in a few extra so my guess its around 3. I guess I could always just push the button on my new dash gauge and it would tell me but I forgot I had the ability to LOL

to answer your orignal question. 16 awg is plenty large to run like 50 led cluster's. 20 led cluster's will pull like 1/2 a amp so your fine. Hook it up !

That pic is crazy! I dig it. <BR> <BR>3 amps is still pretty much, is that for the boat above? I would not want to pull 3 amps through the little bitty wire that is stock in the boat. <BR> <BR>Then again, I have/will have about 1/10th of what is in that boat above. <BR> <BR>Still think I will be ok?

Thanks bro. <BR> <BR>Hey Grant....have you ever put a smoke machine in a boat?

you should be fine. I have close to 20 lights installed and used 20 gauge wire, which is a tad larger than what was in the boat, but not by much. No issues here. I just spliced into the existing courtesy lighting.
