What is the highest watt led light bar my L3240 can run?

4570Man · Oct 13, 2015

I'm looking to mount a led light bar on my L3240. I plan on getting the widest one that will fit in the bottom side of the ROPS and obviously mounting it on the bottom side of the ROPS with a swivel mount that will allow it to point forward or backwards. I'm probably looking at a 120-200 watt bar and just making sure it won't overload the electrical system. It will probably be used with the factory headlights on.

You could run up to 250 watts (20 amps x 12.5 Volts = 250W). It would be a continuous load, so the wiring needs to be at least 12ga. and on a dedicated, fused circuit off the battery.

Not the same tractor, but probably similar alternator output. I run a 108W tied right into the high beam switch, because the high beams are pretty much useless. No extra switch to deal with. No problems so far. Pics are low beam - high beam. I think the 108w is plenty.

Your alternator may be rated at for example 30 amp output at 1800 engine RPM. If the majority of the time you are at 6-900 RPM, you need to know what the alternator output is at that engine speed or you may be draining the battery.

That's really clever! Great idea. :thumbsup:

Do you guys think I could get by with two 150 watt bars or should I back down to a 100 watt? One would be up front in the place of the factory head lights and the other on the ROPS.

Rigid original version D2 35 watts per pair silly bright. Best warranty and reviews I've found, very happy

100w LED will be more than enough light for tractor use, you probably don't even need that much.. Something like this should suffice..

.. I run 150W off road on my jeep and that's plenty in the middle of a blackend trail in the trees...

FYI, save some $$$ and buy from Amazon... Amazon.com: 20 led light bar: Automotive

I've run plenty of these on my jeeps on the trails and fullsize and they are worth the money savings... Even if you had to replace in a few years still cheaper than buying the expensive ones.
