Sold/Expired WTB: MM sandwich

[BugLightGeek]

I'm looking to buy a MadMax sandwich with a Seoul LED for a miniminimag host I'll be getting. I'll also need a 17mm reflector since I don't think the host was bored out for a 20mm.

It will be running off an AA battery.

I'm hoping to find one with a nice Seoul LED :thanks:

anyone? anyone have a sandwich I can buy?
The Shoppe only has 1W LED ones... :help:

 

[BugLightGeek]

hello?

 

[mossyoak]

i havent seen one but if you get lucky and find one let em know.

I wasn't aware that anything besides a Luxeon will fit on a sandwich. Has anyone actually made one with a Seoul?

Yup, I made a sammie with a Madmax plus and SSC USWOI emitter. I'm sure others have as well, it's essentially the same as making one with a lux. I am currently using it in my minimag with an IMS20 reflector. The base of the emitter is a little wider than a luxeon, but it still fits between the contact posts. Just make sure you leave just enough epoxy to electrically insulate the base of the emitter from the emitter board. btw: my minimags are not bored out for the 20mm reflector - I just filed & sanded the outside of the reflector body, mostly around the bulge near the bezel end, till it fit. Takes time, but it's possible.

I'm really pleased with the result, practically comparable to a 6P with a P60 LA with over 2hrs of runtime on NiMHs. I imagine a Madmax Lite or BBNexgen400 with an SSC would be a nice combo as well - bright with a long runtime. Sorry for the tease BugLightGeek but I'm not ready to part with mine yet.

Care to make one for me?

...Has anyone actually made one with a Seoul?

Yep, made several DB's, BB's, Wiz2's with Seoul, and also made some FluPIC's using Seouls. Basically, anything that uses a Luxeon can be made to work with Seoul. The only gotch is that you must insulate the slug from the ground of heat sink.

How much to make me one?

I've got a MM sammie available with luxeon. should be too much trouble to change out to P4. but it may draw too much current.

vf affects amount of current delivered with MM. P4's vf is much lower than any luxeon.

 

[BugLightGeek]

Will it run alright or will you need to add a resistor?
I plan on running it in a miniminimag off (most likely) just a regular AA.

 

[IsaacHayes]

Just a single AA with a madmax and low VF seoul shouldn't matter. In fact lower VF means more current into the P4 since the MM can only supply so much wattage out, the lower the VF, the more of that wattage out is current.

 

[PhotonAddict]

I agree with IsaacHayes. The Vf range of an H or I bin SSC is very similar to an H or J luxeon. As I recall the SSC on my sammie is getting between 550 to 600mA on a freshly charged pair of AA NiMHs so it should be o.k. If BugLightGeek runs it on a single AA (and not a 14500) the emitter would see even less because the MM+ would be drawing a constant 1A from the batteries in both cases so he should be o.k.

BugLightGeek, I'd like to help you out but work and other commitments are keeping me pretty busy at the moment... it would be a while before I could make one for you. Sorry...

Its not a sandwiche but my CMG has a Cree XR-E running off a MadMax Lite (Link in my sigline)
I power it with a 14500 Li-Ion but it will run on a AA withreduced output.
Works great as a flood for walking or looking around in the dark car.
Get the Madmax Plus if you want to focus in a MiniMiniMag and get more lux.

 

[BugLightGeek]

Thanks for the tip, Nein!!

Nein - that's a nice work. Looks like modding CMG's can be quite a challenge. When I tried a 14500 with my sammie it was drawing over 1A on a fresh charge so I figured I'd play it safe - my 2AA is my favourite worklight anyway. I have noticed that the SSC sammie does not seem to generate as much heat the luxeon sandwiches. Presumably because the SSC is more efficient and more of the energy is used to produce light vs. heat (?).
