My New LED Light Bar Specs

I can say this thing outputs near as much light as a thousand watt metal halide fixture of which I have experience only with Hubbell. I am going to check out a downside up visor that keeps the hood dark as night. Light scatter isn't bad but man alive even the faintest of skirts is distracting. I want to light up those asphalt-tinted cattle. And now transplanted antelope. Burros are smarter than horses but I saw a little Nissan awhile back that splatted a badger. Major big-league damage to grill, A/C condenser and radiator
I am going to power the bar up only at 30 mph and faster. Something is nagging at me re the wattage verus the heatsink area relationship. White powdercoated aluminum. Powercoating does BTU no favors. Wish it had come anodized black. Oh well.
