Happiness is a package in my mail from a CPFer. When it's return address is our Charlie "Mr.Bulk" Wong (or some of you fellahs), it becomes joyful anticipation.

I was down at the Ranch on Saturday hunting wild dogs (Bagged: Zero) so when I got back on Sunday I found a priority mail box with this awesome Mag-mod inside.

It is a brand new Mag 3xD cell in that handsome silver finish. It has a Luxeon III LED mounted to an industrial sized heatsink which is Direct Driven by the three D cells.

The lens has the very mild Acrylite (I don't know if I have that spelled right) coating to smooth out the shiny, stock reflector's artifacts. It does this extremely well with what must be only a modest diminishment of output.

I have one of Oto's Perfect Mag Reflectors (cammed orange peel) on order and look forward to trying it with one of the UCL lenses from Flashlightlens.com /ubbthreads/images/graemlins/cool.gif

Mag makes beautiful hosts and I am particularly fond of the 3D. I kept a Mag 3D I bought in the early 1980s in my truck for a decade. Three years ago I destroyed it defending myself against a couple of road ragers who sideswiped me on an Interstate access road and blamed me for it.

They graduated from punks to knotheads, but all I had left was the dented empty tube and tailcap. /ubbthreads/images/graemlins/frown.gif

I replaced it, but then, alas, I discovered CPF. /ubbthreads/images/graemlins/yellowlaugh.gif

Being an ape concerning technology, I can't say much about the innards of this mod. It is Direct Drive and uses a Luxeon III ("3 Watt") emitter that is very white. I don't know the bin, and it doesn't really matter to me. Whatever the bin, it is white and intensely bright like I want 'em to be. Every Luxeon modded head or flashlight I have bought from a CPF modder has been very white and very bright. Binning codes are wasted on this igner'nt, hairy-legged, old country boy. /ubbthreads/images/graemlins/grin.gif

I hope to send it off to Roy for plotting the output/runtime in a couple of days.

It arrived in the host's original packaging inside the box, which is a thoughtful and nice touch. I saved the packaging 'cause it has Charlie's fingerprints on it and will be a valuable collector's item when he and I are worm food. /ubbthreads/images/graemlins/tongue.gif

The workmanship is impeccable...flawless. There is no way this is going to be used as a "Knob-Scobber".

I'll post some photos I took just a little while ago. It was daylight, high noon actually, on a clear, sunny day in South Texas. I took one shot outdoors, the light setting was cranked down to its lowest (- 1.5) and you can see it looks like nightime. My veteran Sony Mavica's overexposure protection kicked in, too. I thought it gave a nice look at the powered up emitter. However, when I attempted to look at it with my nekkid eyeballs I howled that good old Germanic, single syllable expletive and staggered around the balcony much to the amusement of my three Lesbian coed
neighbors.

Edit: The counter top is formica painted dark "Battleship Grey" and the wall is indeed just about that color, I call it "Tobaccy & Bacon Grease Stained Gubmint White". /ubbthreads/images/graemlins/icon15.gif

Here's a beamshot of the Mr. Bulk DD3DIII at a light setting of "-.5" :

Here beamspots are compared between the Pelican M6 Incandescent (on the left) and the Mr. Bulk DD3DIII (on the right). Light setting is "0" :

The reflections mar the photo, but you can see that the DD3DIII's LED output compares favorably with the Pelican M6's 70 something Lumen ( /ubbthreads/images/graemlins/icon3.gif ) intense spot.
Charlie, please correct me if I've erred in my description. Thanks so much for showing me how much light a Luxeon III can put out.

When the Runtime Plot is completed a link will be posted.

Oh, no rechargables for this darlin' /ubbthreads/images/graemlins/icon15.gif. All this performance out of inexpensive Walgreen's alkalines. This is driven at the bleeding edge for the Luxeon III in this configuration.

Looks great Britt.

I am thinking of making a 3D or 3C direct drive mag soon. For a runtime light.
I have a 3x123 DB1227 one and a Uflex 1000 8AA one now.

I dont like lights that dim over time though. (direct drive) /ubbthreads/images/graemlins/frown.gif

Please keep me posted on how long it will run before it starts to get noticably dimmer.

Thanks, and have fun.
 
cool light mr bulk makes awesume lights hey 5 more days to the new moon!!!! its on the 20th i belive fun night to play with lights.coool post i enjoyed reading it

Wow! /ubbthreads/images/graemlins/ooo.gif Jtice, be sure and post about 'em here if you haven't already. I'd be very interested in how those runtime lights perform.

Raggie, I believe you're right on the date for the New Moon. I was just checking that last night so that I could plan on being out of the city for it.

Britt
 
Whaooooooo !
Nice picts, wonderful light Britt /ubbthreads/images/graemlins/thumbsup.gif
But too big for my small hands /ubbthreads/images/graemlins/grinser2.gif
I certainly prefer a super baby pin /ubbthreads/images/graemlins/wink.gif
 
BC0311,

Heres the MagUflex Page.
Not sure why the pics arent showing up. I think logics site has been messing up lately. /ubbthreads/images/graemlins/frown.gif

Thanks Britt. Lesbian coeds, eh? Reminds me of a story:

An alcoholic country boy was whiling away the time at his favorite watering hole doing his favorite thing, when a beautiful woman comes and sits right next to him at the bar and orders a drink. After striking up a conversation with her, she finally turns to him and admits he's wasting his time because she's a lesbian.

Being from the back country he has never heard of such a word so he slurs out, "A lebbian? Whuzzat?"

The lady tells him it means she thinks about making love to women all the time.

"Uh-oh!", says the drunk.

"What's the matter?", asks the woman.

The drunk replies, "Then I must be a lebbian, too!" (drum roll / cymbal crash)

Sorry guys, couldn't resist! /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif
 
i just made a 3d lux3 the other day for somone, and was quite surprised how badly it blew away my 1w 3d of over a year ago! the old one was a ld of unknown bin, and i always thought it was quite bright, but compared to the lux3 version, there is certainly no comparison.

you say you're going to use a cammed reflector? /ubbthreads/images/graemlins/confused.gif
i don't think that's going to work...
a picture of the heatsink/led without the head on would be able to tell for sure.

/ubbthreads/images/graemlins/blush.gif Shows you what I know. No biggie, I like it just like it is just fine. Rothrandir, maybe these photos will help.

Charlie... You weren't s'posed to tell everybody! /ubbthreads/images/graemlins/blush.gif /ubbthreads/images/graemlins/yellowlaugh.gif /ubbthreads/images/graemlins/yellowlaugh.gif /ubbthreads/images/graemlins/yellowlaugh.gif

Hey Pascy, when you get your VIP next Christmas ( /ubbthreads/images/graemlins/yellowlaugh.gif jk) you're not gonna need an SBP.
Britt
 
nope, a cam wouldn't work /ubbthreads/images/graemlins/smile.gif

you might try one of darkzero's reflectors, i have one of his modified minimag reflectors, and he does an amazing job!
i don't have one of his larger mag ones, but as soon as i get some money i will /ubbthreads/images/graemlins/wink.gif
 
Thanks, Roth, saved me probably breaking it.

Roy told me to go ahead and mail the dee dee three dee three to him for runtime plotting. It'll go in the mail to him tomorrow.

Britt
 
sounds just like my 3C mag only yorus is 3D...I guess D's have mroe resistance but longer runtime?

Gotta love the beam those mags with Lux III throw witha sputtered reflector! So far it is my favorite flashlight I have modded...And my first too!

Next project is a boost circuit to keep a Silver mag 3C @ 1 amp (Mr-T?) with a T-binned luxeon.
 
With 3C you probably don't need a boost circuit, unless you have a very high Vf luxIII.
 
Ya, I know, its still damn bright, but im going to keep it at 1000ma untill the batteries compleatly die...I may be picky, but I do notice a big difference after my alkalines get down to sub 600ma...Now on NIMH thats another story, but then the boost circuit shoudl still help some, and since they would be rechargable then the loss of runtime is negligable.
 
your luxeon would have to have an amazingly high vf to need a boost curcuit from 3 cells! /ubbthreads/images/graemlins/eek.gif
i don't even think that'd be possible...

a buck curcuit would regulate the light better...

maybe a downboy 1000?
 
I got on the list for a couple of Darkzero's C/D Mag reflectors. /ubbthreads/images/graemlins/thumbsup.gif Thanks for the suggestion, Rothy.

Britt
 
Justintox: Probably a buck/boost would be needed. A buck to lower it to 1000 when the bats are new, and a boost to well, boost it when they are lower. But it probably won't boost for very long before going out, I would imagine as to bump up the voltage it will have to suck a ton more current than the 1 amp output it will be trying to deliver.
 
Well.... Here's your runtime plot! The runtime calculated out to be 7 hours 50 minutes!!!!! I shut down the plot after 40 hours. For the last 12 hours the plot had been at 500 Fc @ 1Ft plus or minus 30 Fc. That is an amazing amout of light for 40 hours of continous operation.
 
Thanks Roy,

Hmmm, three great big D cells overdriving that poor lil' Luxeon III and it still hangs around for that long? I guess there certainly Must be something different about the internal construction of the Lux3 as compared to the Luxeon 1W. Good news indeed for all who are using it in their extreme-driven lights (like the VIP on "High"...).
