reflector for mag c

[mrmickeyknox]

i just modded a mag c and the reflector is too deep causing a dark spot in the beam. is there a shallow reflector available that would fit?also what is the reflector size for a c cell mag? 48 or 50 mm

 

[gswitter]

How was it modded? Is it no longer focusable?

It's not cause it's too deep. The solution is to get a textured reflector. Will smoothen out the beam at the expense of throw but well worth it.

no its too deep. if you focus it out to the point the head is almost completly unscrewed it works great.the heatsink has a raised pedestal. if the reflector was about a half inch shorter and maybe even tapered more it would be great

It's not the reflector as darkzero has already said. I can't tell you the number of people that have modified maglites with P7s and had no issues with the reflector except that it wasn't big enough to git rid of the hole. The only thing I can think of that might be the problem is the heatsink. Make sure it is down as far as it can go. Tighten the maglite's head to focus. If you hit the o-ring and go past it slightly you're fine. If not, I can only guess the pedestal is too high. Besides replacing the heatsink, file the down the lip of the heatsink so it will go deeper in the maglite's body. It will also help to drill two holes it he heatsink so you can maneuver it with a pair of needle nose pliers.

The photobucket link says it's a P4, not a P7, mod and the very blurry image appears to confirm that. The image also shows that the reflector is incorrectly positioned, which is most likely why the beam has a dark spot. You don't want to bottom the reflector. You want the edge of the reflector opening to be approximately even with the top face of the LED case. Thus, you need to unscrew the Mag head and you should see a big improvement in the beam quality. It's not because the reflector is too deep. You have to put the light source at the focal point of the reflector. At least with the KD OP reflector with the 15mm opening, the OP texturing gave only a minor improvement in beam quality over the stock smooth Mag reflector. For the P4, I wouldn't bother with getting a textured reflector.

I can tell by the gold anodize that that is on of the first run Brightlumens C heatsinks, or one of it's clones, where the pedestal is too high. The newer ones Jo offers are much shorter. You can take off the lip and sink it down into the body, or sputter the reflector. That's definitely a P4 by the pictures, so no dark cross pattern, just a hole.

 

[mrmickeyknox]

yes its a p4. and yes the light sits way too high. thus causing me to think that if i got a reflector that was less deep it would fix this. i gues cutting off the lip would work but with the driver in there there isnt much more room to push it down without possibly kinking a wire. im not trying to be hard headed and its not that i dont belive that you know what you are talking about cuz i do ive learned alot from you guys on here. but is there a reflector that is less deep. just pretend im not even going to use it on this light. :thumbsup:lovecpf

it is a lightmania hetasink.

I don't know of any maglite reflectors that are shorter. You can modify your current reflector, but I can't say how well it would focus. I think grinding down the lip on the heatsink would be the most if effective fix. Coil the wire in the maglites body to prevent kinking.

 

[mrmickeyknox]

thanx ill have to try that.

 

[mrmickeyknox]

well i think i fixed the problem. 1st i cut off the top of the reflector, about 1/8 of an inch. glued it to the lense now making it one piece so if i break my lense ill likely have to replace the reflector too. 2nd i put some loctite on the threads and adjusted it to the best position it is not focusable now, but the oring isnt showing and the loctite eliminated the head wobble. i couldnt stand that, made it feel cheap. overall i am very satisfied with it. for a p4 it puts out a decent amount of light. much better than a stock c cell mag. cant wait to try modding my 2d mag with the p7 direct drive. thanks again for all your help and suggestions.

The WF-500 Reflectors are very shallow, you could modify it to fit in your Mag by shaving down the threads near the lip.

Here is one example

or something like

this one

or this

I believe they were also available in SMO finish for better throw.

Are you sure that your LITEmania CMag, gold anodized heat sink is for a P4? It looks like it's for a P7 based on LITEmania's sales thread on CPFMP. His English language web site has conflicting info on the gold anodized heat sink. The title says it's for a P7. The text description says P4.

The pedestal has a slight recess to help center the LED. Was that recess a perfect fit for the P4 or was it oversize? If oversize, then the heat sink is for a P7 and that probably explains why you have to unscrew the Mag head so much.

Even if it was used for the P7, it would still be too tall. It is either an exact copy of Brightlumens first run of "C" Mag P7 heatsink, or they purchased all of Jo's leftover stock. They are both too tall.

yeah i looked at those. i wasnt sure if they would fit but yeah i think ill try that. thanx, glad someone doesnt think im a complete idiot.
ill probably end up getting one of those but for now i pretty happy with the chopped mag reflector you really cant even tell. that is until i get done with my 2d p7. think ill use the 3 1/2D-Size NiMH Rechargeable Batteries that you recommended aircraft800. you have been a great help with everything. i appreciate it.
