2D Mag goes 4*Seoul (w/ pics, now w/ beamshots)!

[Nereus]

Seoul is clearly brighter, no doubt. BTW, nice avatar!

Re: 2D Mag goes 4*Seoul (w/ pics)!

Good job! :thumbsup:

I'm wondering how you could keep the reflectors centered. :thinking:

It's a secret?

 

[Nereus]

No it is not... I am making step by step pictured guidance how I made this mod: https://www.candlepowerforums.com/threads/153982 . I used the same technique with it. So, it is a matter of days that you will see how I did it.

Nereus, What do you think the lumens output would be for this 2-D mod?

Greetings!

Nice job! Where was the switch and cover obtained? I have a project i'd like to use that in...

Best wishes,
Bawko

Thanks! I have heard about "up to 240 lumens at 1A" marketing mambo jambo for the u-bin P4 led... I think some 200 lumens per emitter at 1A is closer to the thruth, so that is 800 bulb lumens. Throw in to the equation 30% optics losses (that is general CPF consensus) and we are talking about 560 torch lumens.

I bought the switch and cover in a finnish electronics store called Yleiselektroniikka... But that is a very common switch, you should find it in many international electronics stores. It's produced by Apem.

Okay guys, it is time to reveal the secret - have a look on this thread https://www.candlepowerforums.com/threads/156336 for a description about how I centered the leds.

Nice mod Nereus! Are you satisfied with the switch and cover? If so, do you have the part numbers/manufacturer so I can locate and purchase as well?

Thanks!
Charlie

Thanks! That's Apem 5000 series three stage (on-on-on) double pole 5644 switch. Here is the Apem catalog page where you can find it: http://www.apem.fr/pdf/uk/section_a/05-Serie 5000-A-structure.pdf . The switch cover is U1231 neoprene sealing boot, see this page of Apem catalog: http://www.apem.fr/pdf/uk/section_h/01-Boots-A.pdf . And yes, I have been satisfied with the switch and the cover - no problems so far.

If you are using alkalines you might want to use similar kind on-on-mom Apem 5644 switch. Like that the high mode would be momentary on only which is good because the runtime @ high would be quite short with alkalines.

oh last thing, im usung some So2Xa reflectors, will these fit the seoul LED as well?

Do you mean IMS20 reflectors, like this from the Sandwich Shoppe?

I have tried IMS20 with the Seoul P4 led and the combo produces usable but a bit unfocused beam. If you remove material from the back side of the reflector you can improve the focus.

BTW, nice avatar - it is a pity that CPF rules do not allow bigger ones!

Nice work. Can you show a beamshot between this and your maghid?

Yup - I just have to see when I have time to take the beamshots...

That is a sweet Mag Nereus. I didn't even know they made Mags in green. :thumbsup:

 

[Nereus]

Thanks! You can find magseoul and maghid comparison beamshots here.
