not true with aspherical lens

I have accidentally dedomed one sst-50 and it lose lux with asphericals

That might depend on the die size VS size of the aspheric.

My dedomed SST-90 throws a hell of a lot further than my domed SST-90 using an aspheric in a P60 sized head.

Re: Enter The mag Dragon

That looks cool.

I will wish for a lathe for you for Christmas!

Yeah, yeah..... rub it in :rolleyes:.....:D.......;)

Re: Enter The mag Dragon

Hurry up and finish, I need an idea on what to do next since my stock led maglite throws the same as my kd aspheric xre!!!

Re: Enter The mag Dragon

too cool.. Nice work as usual:thumbsup:

Re: Enter The mag Dragon

Thanks & Sorry guys, I am a little slow.

I am running into some hurdles , some part are still on order, can't finish it up yet, but I do have some progress made. Will post some updates tomorrow.

Re: Enter The mag Dragon

did u decide on what driver ur going to use ?

Re: Enter The mag Dragon

Yes, DIW's Linear driver special made for me at 7 amp.

Re: Enter The mag Dragon

Got to keep my promise, so here are some updates:

I soldered 22AWG wires to SST-50 & used Arctic Silver to glue down to the brightlumens mag D SST-50 HAIII heat sink. I am pretty sure this is enough to handle the 2Amp over spec on SST-50, but only time could tell for sure,

No one has tried to drive SST-50 this hard as far as I know.


I grind down 2-3mm from bottom of the Mag D switch & wired a copper pad as the positive to connect to switch
core with super short 18AWG wire, this eliminate the factory "leef spring connection" on the bottom side,
reduce resistance or possible sparks at high amp.

What's the big deal with the extra 3mm? You'll see.


As far as battery of choice, I have previously sold a Mag 2D SST-90 runing on 4x 4/5 Sub C. http://www.candlepowerforums.com/vb/showthread.php?t=278919
However, I have since worked out fitting 4/5 Sub C into the much more compact Mag 2C (FS at B/S/T):
http://www.candlepowerforums.com/vb/showthread.php?t=281139
Since Mag D tube is so large, it'll really benefit if I could fit much bigger NiMH in there.

Enter The 4000mah half D NiMH:

These 1/2 D are rated 12Amp max current, they look huge next to the 4/5 sub C.


However, the 4x 1/2 D is just slightly longer & needs to go into the tail cap. So I bored out the tail cap:


This turns out to be an unexpected challenge, as the battery hasn't gone into it deep enough,
I have already bored open some area that I cold see the threads, see the dark "cut" right above the "shelf":


Unwilling to bore it out any further & risk of detaching the thread section from the rest of the tail cap,
I could not close the flashlight, there is a small gap remaining even with the extra 3mm space gained
by grinding down the switch:


The good news is: I think the gap is small enough that I could fill it with Down load's mag Ring 2: http://www.candlepowerforums.com/vb/showthread.php?t=178764&page=12
This will also allow to JB weld the Mag Ring to the body, therefore beef up the section that I have filed
open some "cuts".

The bad news is, that's a delay of 2 weeks perhaps? :banghead:
I just placed my order & haven't gotten a response yet.

Do you have a link on the 1/2 D's? I looked for them before I settled on the 4/5Sub-C's I ended up using.

Re: Enter The mag Dragon

I think it's time you bought a mini-lathe :)

Re: Enter The mag Dragon

+1 on the lathe for Christmas. He reminds me of darkzero in his pre-lathe days. I always used to wonder looking at his posts, "How'd he do that without a lathe?"

Only one seller on ebay has it. Hi amp type.

Re: Enter The mag Dragon

Hey I have a question...

When you used that heavy gauge wire, did you have any issue getting the led to sit all the way into the pocket? The last one I did would not go down as the wires would not fit into the milled pockets very well. I had to mill the area where the wire travels to get it to sit where it should.

Max AWG is 20, I bend the wire 90 Deg. test fit first, tight but do fit.

22 AWG is eazier & still good for 9A.

Re: Enter The mag Dragon

While waiting for the 7A driver & Mag ring to come, I measured the LED Amp with IMR 26650 direct hook up an AW IMR 26500 w/o flashlight light body. It came out to be 7.3 Amp :eek:. I got lucky on this one in terms of low Vf, because for all the SST 50 & 90 I bought from various places (Photonfenetic, Avnet,4Sevens etc., I have never had a SST 50 or 90 went above 6A when direct hook-up to IMR 26650 or AW 26500 IMR.

So I decided to build a short Mag 1D body for this low vf SST-50 for now,
Just so I don't have to wait any longer. I cut a 3D Mag down the same
way as shown here, but I think I am getting a little better each time:

MagDragon 1D Shorty:




When not using the dragon head, mated it with a Sputtered mag reflector
give a nice beam.



Light engine inside Inside the Dragen head:
I had to grind down the DIY adaptor inside thread, remove about 1/2 inch of thread to allow mag body to screw in deep enough for optimal focus.



Beam shot about 20ft away next to my 52 Inch Plasma TV:
It has a very large spot due to the short EFL of this lens vs. my previous built magDEFT SST-50 which used a Automobile 3" Projector lens which had longer EFL ( http://www.candlepowerforums.com/vb/showthread.php?t=268894) The spot appears just as bright if not brighter & the Total lumens went into the spot have increased a lot.


I realize that was not very smart after I took this shot, as plasma TV is prone to be bleached, hopefully no perminant "dragon stain" :crackup:


Up against Ledean Mag 1C Aspherical 52mm lens


MagDragon Aspherical 1D on Top/Leaden mag Aspherical 1C on bottom.


Super low exposure at ISO 1000, 1/1000" F2.6.


here is a beam shot with the dragon 1D body with sputtered mag reflector in regular Mag D head, same 20ft distance:


The Goodby shot:
(I wasn't really going to say goodby to the dragon, I just couldn't put it down, I kept admiring it & this photo came out as if I was going to say goodby :nana:).

Nice results.:cool: Does your 3" Franken-DEFT lens fit this head?:naughty:

I sold the magDEFT but I am sure I could make it fit.

Are you winking at a possible dual lens system?

I have cooler mods cooking, but too early too spill the beans...

Dual lens system? :confused:

I am not talking about this light :-)
