Will a 20 amp toggle switch be fine with 5 of the 27w leds wired to it?
27w X 5 lights = 135 watt
If you are running them on 12 Volt then Divide by 12
135 divided by 12 = 11.25 amps

So the answer would be yes
 
Just ordered 18 27 watt led's from customfitz. Cant wait to get my lights and put the generator away. Stealth mode is gonna be incredible!
 
Just got my 10 27's in today, can't wait to get the deck back from being modified so I can hook em up and enjoy the silence of the night. Thanks again Custom and I'll probably be ordering a few more once I get these hooked up and see how they look.

Quick question tho, what gauge of wire should I be running? Plan is to run 24v power to 2 switches (one switch for the left and right sides of the deck and the other for the front lights).

look around but your best thing would be ask obg or jeff that already run them to help with that

If you split them into 5 on each switch...27watts/24volts=1.125amps x 5= 5.625amps. Find a wire size chart to get the size you need.
 
Wiring DC LED's


Note. If you can get actual input watts or amps of the manufacture use those numbers. ( a 27 watt led is not actually 27 watts it could be under driven by the manufacture, or over 27 watts if driven by another powers supply built into the light.



1 ------ Light load in amps or watts?
27 watt LED divided by 12 volts = 2.25 amps
27 watt LED divided by 24 volts = 1.125 amps

Ex, 12 LED lights @ 27 watts each----12 light times 27 watts = 324 watts total
or if you know amps per light -----------12 lights times 2.25 amps = 27 amps total (12 volt Led)
or if you know amps per light -----------12 lights times 1.125 amps = 13.5 amps total (24 volt Led)

2 a -------Wire length in feet from batteries to terminal block ? Ex. 14 feet of wire.(See drawings)
324 watts @12 volts and 14 feet of wire = #6 wire
324 watts @24 volts and 14 feet of wire = #12 wire
27 amps @12 volts and 14 feet of wire = #6 wire
13.5 amps @24 volts and 14 feet of wire = #12 wire

2 b -------Wire length in feet from terminal block to 4 lights ? Ex. 10 feet of wire. (See drawings)
108 watts @12 volts and 10 feet of wire = #12 wire
108 watts @24 volts and 10 feet of wire = #14wire
9.0 amps @12 volts and 10 feet of wire = #12 wire
4.5 amps @24 volts and 10 feet of wire = #14 wire


3 -----Use OBG’s chart to find DC wire size. http://bow.fishingcountry.com/forums/entry.php?284-DC-Wire-Size-Chart
Top chart is for 24 Volts DC
Bottom chart is for 12 Volts DC

Column 1 of chart is for amps ( when amps are known ) find your total amps then follow row to the right to your feet of wire to terminal block then follow that column up to the top to see wire size.

Column 2 of chart is for watts ( when watts are known ) find your total watts then follow row to the right to your feet of wire to terminal block then follow that column up to the top to see wire size.

Just ordered 4 50w, and 27w lights. Looking forward to sweet silence! Thanks Custom.
