If all you're concerned about with the Surge is the bulb burning out, just bring a spare bulb, and a keychain LED light so you can see what you're doing while you change the bulb.
The brightest AA LED light that I remember hearing about is a 2D Mag set up like a Space Needle II, with a Hotlips-type heat sink and 5 watt LED and six AA's. But maybe that's not what you wanted to hear. Actually I now remember Mr. Bulk made an extension tail for the regular SN2, that let you run it on six AA's (this may have been the famous "Assault and Batteries" whacklight; my memory is hazy by now). But that light was almost 2 feet long, so maybe you'd find it even less practical for camping.
Another cheap incandescent alternative is get a 2D Brightstar plastic industrial flashlight and load it with six AA's and a KPR112 or KPR118 bulb. The Brightstar has a spare bulb compartment in the tail (like a Mag), but it weighs a lot less since it's made of plastic. Output should be in the same general class as your Surge, though the light will be a little bigger.
Really, unless you're camping under battlefield conditions, it's not that big a deal if a flashlight bulb burns out, as long as you have a spare.
