We've installed both the Whelen and Sound Off LED floods on our work trucks and they do alright. Have some Magnalight 50W HID's on our Hovercraft that absolutely Scream ...... but you have a relatively high startup amperage until the lights warm up. Best I've seen in LED are the Whelen Pioneer Plus, not the standard Pioneer's but the Plus versions crank out some seroius light (doubles are pushing 14,000 lumens). Down side is they're spendy, but cheaper than VisionX or Magnalights. You can buy the LED bars from Magnalight or VISIONX but the 25,000 lumen bars are around two grand.
