I am all LED on the plane, but..... on my 4X4 Cummins diesel truck I have a set of 450 Watt 28V PARs in the winch bumper with a special power set up to run them, 16 AMPs each @ 28 V. These are the brightest lights I have ever seen. lighting up the reflectors on top the snow steaks for many miles ahead, and will auto ignite a piece of paper if held in front of them.
