They are 18 Watts each so pull 1.5 Amps each.
Besides the added lumens, the CRI is pretty good which improves what you can see with each lumen. I really am very pleased with them. I have a third one - thinking of mounting to the back of the Fops facing the rear but i might replace the existing one instead. I will do a temporary install on the FOPS and see what i think. With the fops mounted to the front of the tractor, the articulation meand the light could easilb be facing the wrong way but it might have enough spread.
By the way, i double nutted the lights tight enough that tey stay put but i can rotatet and angle them to point where i need then to.
