Sure you can. You just need 6 D nimh cells(the costly part of it), to go with a glass lens and metal reflector. That's really the only difference your battery size.
Output should be close to the same as your 2d if you're using good cells in your 2d that don't sag under the load.
The 6d is going to give you great run time and the cells should be able to sustain the voltage better than most AA's.
Watch them when they're fresh off the charger. I use 6 sub c's in a 4d and they'll flash the high bulb after an hour's rest. The D's might have a similiar affect.

The 6D ROP is the easiest to build. I would be careful putting 9V's to the ROP bulbs.
RickyT: What brand SubCs are you running?
FILIPPO I dont know how much alkaline Ds sag under 2Amp drain, but I think it will be enough to use safely. (I could be wrong, sorry). I think some people have used the ROP low like this. I cant test the Ds, but from other tests I know the ROP Low takes abuse very well. Design Voltage 6.0, Power=11W I = 1.85.
I have driven ROP low with 8.55V on, 1.99A, 17W (for short runs..) This is more than what i think Ds would deliver. Maybe try with multimeter measuring Current at tailcap. If its around 1.9A, you should be fine on alkaline. Just expect diminishing output as batteries get used up.
good luck

Gday FlashSpyJ,
Most simple mod I can think of like that would be use 18AA rechargeable nimh (or 16 or 17,, I dont know, depends on batteries and lamp need to test) and put MR16 halogen downlight into the mag head. I'm not sure about D maglite, I have C size, and use 35 W Osram Decostar IRC, driven at 17Von, and 3.6A =61W. This is very white, but 10 degree beam, so lots of light, but doesn't throw like ROP. Lots more Lumens, maybe less candlepower... But looks great and lights up whole house, or field..
CAUTION. I only use mine for 15 seconds at a time, just for quick checks outside, house so heat is not a problem for me, but may be if used longer.
I have Tested 50W osram decostar IRC ((Infra red coating) high efficiency), and pushed to 101Watts. (20Von 5A) Also extremely White. Standard lamp life is 4000hrs at 12V, but when pushed, maybe 5 or20 hours.. I dont know. But push less = longer life of globe, but less light and less white.
Search cpf for "Mag MR-16" page 3 of search has many talking about it. I just looked randomly, but you should find plenty. Some use 75W globe.
My advice, if you do this, is drive the globe hard. Better to push 35 watt globe to 60W, than to push 50W globe to 65W. I have tried both. Only when pushed hard do they become worth having. Heat issue may be, because they reflector allows heat behind, but metal maghead shouuld work to get rid of it. This you must check. Ask others who use for longer..
To fit it, remove globe and reflector, and make adaptor to make pins of MR16 lamp contact inside where bulb sits. You maybe can use wire to make a different circuit, but i use wire and electric tape to seperate pins and make contacts for where the bulb goes. Looks funny, but works great. Also, i just use standard lens to hold main lamp in head. Again, I have no heat problem because very short use..
Maybe this is what you want. Lots of Light.. Very cheap if you have batteries.. And very fun
good luck

I have done a Mag 6D ROP mod just yesterday. I used the following parts;
Mag 6D
6 x 2600 mAh Uniross rechargable D cell
Pelican 3854 bulb kit
MagCharger glass lens (fits, but the lens retainer doesn't screw all the way down)
FiveMega dual function MOP aluminium reflector
All in all, the upgrades cost about the same as the price of the 6D originally. Estimated output is approximately 2.5 - 3.0x that of a stock 6D. And the FiveMega reflector makes it a nice, smooth beam at that.

HI MikeSalt, aerosimon here, I was eyeing those dual function reflectors. Can i ask how you find it. Do you have any spread adjustability or is it just set at max focus? Also if you've tried the Bulb with a normal reflector, are the overlapping 'batwings' completely gone with the MOP? Like perfect spot.. surefire like??
I have a 6C, and had both original krypton and Xenon bulbs, plus the ROP in now using plastic reflector. How do the normal spots compare size and cleanliness against the MOP. Any chance you could measure the spot width at a given distance so i could work out an angle. Im a bit technical and it would really help me understand and choose MOPvsVLOP..
I have a smooth setup if you want to trade numbers I can do that in case you dont want hassle with all that work
Sorry about my begging

ps: I am making a sign saying: will dance for technical info

I am using the tenergy 3500 mA cells with tabs. I got about 41 minutes straight run before it dimmed, and had used it 3 or 4 minutes off and on before the run test. Pack was at 6.2 volts when I checked it after the run, this was on it's second cycle. This seemed like pretty good results, but I don't know how they'll hold up over time.

I have 2 6D ROP's, they are pretty cool. UCL lens, MS camless reflector, 6 CTA 12000mA batteries, 3854 HALO.
Hi Pokerstud,
I am asking some ROP questions about reflector quality/spread in the main thread. You have Medium stipple reflectors running. Any idea how much wider the hotspot is than with a smooth setup? I have just posted my rough measurements of mags plastic one giving about 4 odd degrees of hotspot spread (60cm at 8.3m average).. Can you help me decide on a reflector based on cp/hotspot size vs beam quality..
Cool setups, by the way. Lotsa run time
thanks, aerosimon

Aerosimon,
It is adjustable for focus, and yes, at maximum focus, it is a very clean beam. Of course, I do not own a SureFire, but from photos, I can say that it is a SureFire-like beam. When you adjust the focus, there is a hole in the centre of the beam, similar to the stock reflector, but alot smoother.

Thanks MikeSalt, great to hear. In the ROP thread, someone said (apologies to the helper) that a surefire is similar to Light Stipple. Based on my looking at Photos it seems that LS and MOP are in the same region of beam quality.. Thanks again
Filippo, 2200 is about standard AA capacity. (maybe 25minutes total good runtime on Hi).. Pokerstud is using 12000mah Ds which would give 2.5-3hours.. Just think about 4200mah per hour since drain is about 4A..

do you know where I can buy six Ds 12000mah?
