Simply put, what flashlight puts out the most lumens and yet runs off of normal Alkaline batteries? (preferably D cells)
(Yes, I understand the inherent limitations of the Alkaline chemistry that limit the current draw. So the solution seems to be in a simple parallel arrangement of cells. Such as sets of 3D in series... in groups of parallel.)
I have in mind a large lantern style flashlight running on 12 D cells, with 3, 5 or 7 5watt LED modules in a large copper or aluminum machined head with heat sink fins. Price, $200 or more, whatever it takes. But the point being, one can load it up with a dozen cheap Alkalines for $5 and get 2 or 3 hours regulated run time. A wall of light. That's all. Nothing fancy schmancy!
Or should I get four 3D MagLED flashlights and strap them together with stainless steel hoseclamps and chunks of rubber tire between them for spacers? This would be a poor mans solution, and not nearly as bright as I would like, but at least it is "off the shelf" and rugged with LONG run time too. See what I am getting at? An LED bright super utility lantern that runs on cheap D cells but can itself cost a small fortune... Does anything like this exist yet? Sigh.
I await the ridicule...
