I’m wondering if this is even possible. I would like very much to do this myself. I have some experience soldering circuit boards but I lack the electrical engineering skill needed for the larger portion of this project. What I have is a 12” Mag Lite that requires (3) ‘D’ Cell Batteries. My Wish list is to replace the filament bulb with a 12 volt 50 Watt Cree LED AND replace the batteries with quick recharging Ultra Capacitors. I would like to leverage the existing hardware of my flashlight and just add the upgrades if possible.
I know this sounds ambitious but is this even possible.
I have done some research and I think I need the following…
How much energy would those ultra capacitors carry? With a 50 Watt it will probably only light up for a slight or even split second. They put D-cell in it for a reason: Amp-hours

I have done some more research and your are correct - Ultra Caps would not do the job.
DanV:
I think 50 watts is unreasonable - this would be brighter than an automotive headlight - way overpowered!
I have a 1 watt flashlight that is hugely bright! 3 watts would be super bright.
Remember that 50 watts is the power draw for the LED - you can’t compare that to a 50 watt light bulb at all.
It’s the lumen output that determines how much light output the LED has.
50 watts at 12 VDC = 4.17 amps - pretty big load!
do some more research …
Actually, it is an Automotive headlight I’m wanting to put into a Maglite. I’m wondering if I could use (8) 1.5v batteries in series to generate the 12v needed to power the LED. Would something like that be possible?
Apparently The Ultra Caps wont work. What I would like to do is see about completing the second part of my project. I have an old 1,000,000 candle power spotlight that is very big and bulky and does not even hold a charge anymore. I was hoping I could get away with an update to my sleek looking maglite.
Is is possible to get that kind of illumination out of a maglite with some elbow grease and solder?

I think you need to do more research on the basics of electricity. Especially Amp hours… There is a reason why high powered lights have huge batteries.

Thanks for reality check guys. I'm guessing my ambitions exceed science.
If I may make a request (and the forum would be amicable), would anyone suggest a conversion setup that would max out the lumens and still give me close to an hour of use time?
I really want to make at least a go at this if nothing else but to learn a few things.
