Mag ROP, Help!

[rockz4532]

I've been doing some research, and I've decided to
make a ROP 2d mag in the next month. Problem is that I barely know how to. Here are my questions:
1: Does the stock switch need to be modded, and if so, how?
2: Which batteries work best for the ROP Hi, and where can i get them? (i can't seem to find the CPB1650's)
3: What adapter should I use?
4: Where can i get a cheap, but usable metal reflector for the Mag?
5: Can I use the Mag glass lens i got from DX? Is it suffice for the ROP?
6: Is there any other Mag hotwire mods around the same price, with more brightness?
7: Could I use Li-ions for the same price? Is it going to work well?
8: Do any other parts need to be modded?

Any Idea of the total cost minus the Mag?
Does any store sell all of the parts?
Is there any precautions or warnings I should know before using/building the light?

Any answers appreciated, and if anyone wants to sell some ROP parts to me, drop me a PM (though I am still researching a bit.)

I think this LINK and this LINK will answer all your questions.

1. I did not, and mine works fine. A mod might help though.
2. Eneloops work fine, but try the Elite 1700 from CPB as a replacement for the CPB1650's
3. FM
4. FM
5. Sure. Glass is fine.
6. Mag85??
7. Not sure.
8. Nope. But resistance mods might help.

Ok. Thanks for the information, my parts list so far is:
6x2450mah Energizer's from lighthound (Will this work?)
1x Borofloat lens from lighthound
1x ROP bulbs

Possibly reflector and adapter from CPFMP. If not, I will use this adapter.
Has anyone had experiance with this adapter?

I have that very same adapter and it works fine for the ROP. I'm using AA Sanyo Eneloops because of their low self discharge rate.

For those batteries, see SilverFox's NiMH shootout -- if those are the same thing as the 2500s he tested, they're not bad; they won't hold voltage (and brightness) quite as well as Eneloops, but mighty close, and longer runtime.

I'd tend to go with the Eneloops anyhow, because you can leave the light on a shelf and come back a month later and get full brightness out, but if you can take the time to charge it before each use (or can't let it sit a week between using it :)), they look pretty good.

6: Is there any other Mag hotwire mods around the same price, with more brightness?

With your proposed set-up. You can add a bi-pin adapter from FM (or others) and you'll have other bulb options - WA1111 (not quite as bright as ROP Hi), Philips 5761 (brighter than ROP Hi), etc.

 

[rockz4532]

Everybody, thanks for the replys.
As for regarding the batteries, I am changing my plan. Eneloops are what i decided on, but there are none in any of the B&M stores around, so do you think ROV Hybrids would do fine with the Hi bulb? Would it be matched or slightly less runtime&lumens? Would it provide the ~4 amps needed?

ROV hybrids are on sale at my local sears for 5 bucks for 4 batteries, so it is just a cost-saving choice. Of course, if it doesnt drive the bulb well enough, I will use eneloops (or duraloops)

supasizefries,
does the adapter work stock with no modifications? Also is it well built for ~$20?

Any other recommendations before I start ordering?

Also, is there any cheap (~$20) reflectors I can get that will fit the ROP Hi? The camless M2 reflector from the sandwich shoppe does not fit the hi bulb, and is a little bit pricey.

 

[DaddyCool]

Here is my question: When modding to ROP Hi, it's necessary to change the original socket, isn't it? (but not for ROP low, eh?)

The adapter works in the 2D MAG, no mods needed. I can't complain about the build quality.

Here is my question: When modding to ROP Hi, it's necessary to change the original socket, isn't it? (but not for ROP low, eh?)

I'm using the original socket for the potted ROP hi bulb, no mods needed.

I have flashlights with the adapter from Sandwich Shoppe, MDOCOD and fivemega. The Sandwich Shoppe one works good but it is easier to charge the ones from MDOCOD and fivemega with an RC smart charger. This way you charge the whole pack at once and it takes less then two hours. You can buy just about everything from fivemega and then you end up paying less in shipping.

 

[Badger_Girl]

IMO, fivemega has the best adapters and sockets and reflectors...

you can get almost everything you need from him.

Assuming your build is for a 2D/C maglite

1: unless your going to a high current build [50W+] your don't going to need to work with the switch
2: Eneloops, Elite 1700s [www.thomasdistributing.com for Eneloops]
3: depending on what you have available, FM's 6AA-2D work fine, Mdocod's 6AA-2D work fine, If you managed to find a few 6AA-2D magamod's adapters, they will work as well.
4: Check with Litho123 to see if has any reflectors left, if not, contact FiveMega [FM], while his MOP Cammed reflector works very well...its a bit on the expensive side
5: if its glass, chances are it will work. Many where would consider UCL for higher light transmission, personally I use Borofloat [Boro-silicate] window obtained from lighthound, its more temperature resistant and prevents shattering as I use my mag hotwires in the rain occiasionally.
6: Aside from the Mag ROP, theres the Mag11, Mag61, Mag85, Mag64, Mag623 [or USL, aka paper burner], Mag625...etc. The 3D Mag85s has slightly more parts than a ROP: WA1185 bi-pin lamp, G4 bi-pin to PR adapter from fivemega, and if your using NiMH in a stock maglite: 9AA to 3D adapter.
7: Sure...if you can stuff 2 18650s in your mag in series it should work. Any other variants may not be able to maintain the proper output because the lamp current consumption is too far above the batteries ability to provide [asuming we are talking about protected cells here, I'd keep the max output in terms of amps to be around 2C, C = capacity in AH of the cell]
8: You have the option of cutting down resistance using a gold spring, or simply a jumper from the tip of the spring down to the bottom, removal of anodizing in the tailcap. Modding the tailcap to use a MOSFET switch, replacing the lamp tower with a softstarter...etc.
But for a basic ROP mod...the only thing you need is:
A new window [Lighthound, $6]
A new reflector [FM, $25]
A new lamp [comes in a set of high and low lamps, keep the low under the spring as a spare, lighthound, $10]
A set of 6AA identical brand NiMH cells [$10/4, so it works out to about $15]
A battery holder [FM 6AA-2D, link here, $37]
FM will include a male charger plug to use with the built-in charger port in his adapter.
I recommend this charger for your eneloop pack [Battery junction, $26], When you recieve the adapter, choose a connector accessory you don't use and cut the end off, solder on FM's included adapter plug (CENTER IS POSITIVE) and you are set. [I've snipped my Male Tamiya to Mini Female chord for this particular mod, because I can use the alligator clips for other uses]

and it should work as intended for as long as the batteries/lamp lasts.
It works to about $120 before tax, shipping, etc...excluding the maglite...not bad in terms of price really. :grin2:

Good luck on your build:twothumbs

I wanted to try out a ROP, but I wanted to do it on the cheap. I got a reflector from KD for $10. I picked up the bulbs from a Pelican dealer in LA for less than $8 a set. And I used a couple protected 18650s that I use for other lights. Then I made a spacer from wood. Works, but I have to triple click the hi bulb due to the protection circuit on the batteries.

I still have the plastic lens, but it's ok if the light isn't on for too long.

Why stick with the plastic lens, the glass lens from flashlightlens.com or the one from KD are very cheap.

 

[ampdude]

I agree, and pick up a few in case you break one.

 

[greenLED]

Anybody tried a ROP Low bulb with some older Pila 18650's?

I'm wondering whether their rather conservative protection circuit will power that bulb or if I need AW cells.

 

[ANDREAS FERRARI]

It's too bad AW can't offer his C-size Li-ions anymore-decent runtime and no double clicking.Although it took forever to charge them up!

His new IMR ones should be available in a few days.

 

[bguy]

I do plan on replacing the plastic lens with glass. I just haven't done it yet. I don't know about Pilas, but I have protected DX 18650s, and they can do the ROP low on the 1st try.
