Re: In search of the perfect 12v, LED lantern
The Davis Mega-Light meets all your criteria other than LED bulb. With .11 amp power draw I don't think I'd bother switching to an LED bulb. But if you wish to switch after market bulbs are readily available; search Davis Mega-Light and the LED replacements pop up.
