FM's 2" Deep Reflector For LED Mag Mods

[darkzero]

I was given the opportunity to try out Fivemega's deep reflector. Same reflector that was offered here except it has a 15mm opening & does not have the cam.

Performs very well with my P4, LuxV, & Solarc HID Mags. With the P4 the beam is very very tight! With a P7 at it's tightest focus there is a donut hole much like the stock smooth Mag reflector. The donut hole disappears when focused out with some artifacts. Throws very nice with less artifacts than the stock smooth Mag reflector. A great alternative for those who are looking for more throw without the price of a 2.5" head & having to risk modifying it.

According to FM there are not too many of these left but he will offer them for sale. Not sure when but please keep a look out for his for sale thread if interested. The reflectors are only available in smooth. I plan on getting another one & sputtering it to see how it performs.

I tried & tried to take pictures to show how this reflector throws. Unfortunately I'm not a camera man & I failed miserably. Any tips are greatly appreciated. :help:

Sorry for the bad beamshots. I know they don't really do any good but it's all I can offer as of right now (I'll update them if I can get better ones). :shakehead

DarkZero, what kind of side spill do you get with the 2" reflectors? How improved is throw over the stock reflector when used with a P4?

 

[rizky_p]

did you cut the cam?

 

[darkzero]

Nope, as mentioned, straight from FM with a 15mm opening.

Didn't really pay attention to spill, I'll check that tonight. Throws very tight beam with the P4 with not dounut hole at focus. With a Cree beam should be even tighter

Thanks for the heads up Will, I just ordered a grey one to try out

Just a FYI if you PM Fivemega he will tell you what he has available

Exactly. He only has a handfull left. Hurry fellas. I may be picking up another one today. They may be gone very soon!

DZ, When you get your second and sputter it please post and let us know how it worked out. I just got mine and it is a great thrower but if the sputtering doesn't sacrifice to much throw I might give it a try.

I picked it up already but haven't got around to it. Planning for this weekend. I'll definitely post here though, I owe it to FM.

I'd love to hear about how well the 2" reflector compares to the stock maglite reflector.

Is the 15mm opening a tight fit with a P7 or is it allright?

darkzero, did you have time to try it out?

 

[jag808808]

dz,

How did the spill come out? I am deciding which one to purchase. The 2" is quite a bit cheaper. I like alot of spill from my P7. If I require throw, I pull out the aspheric. I would like to know your results as for side spill. That will be a deciding factor for me.

Aloha,

I have a dumb question. Does this increase the throw or is it just blocking spill? Hypothetically, let's say we tripple the depth of this even more. It would seem that there is a point where increased depth won't increase throw and creates a tunnel effect that essentially kills the side spill. I don't know much about light physics, so someone inform us. Because in my mind, it would seem like a reflector that is steeper than 45 degrees would be wasteful.

DZ,
did you ever get around to sputtering one of these and if you did how is the beam?

Reflectors reflect light, not just block it, so a deeper reflector takes spill light and adds it to the hotspot.

 

[James35]

Yes, I understand that, but exaggerate the reflector depth 10 inches, 20 inches (for example). Does it throw any better? Who's good with light physics? There must be a point where the reflector angle starts to lose lumen output.

There is a limit for that and depends on angle of light spreaded from light source and ofcourse size of bulb opening.
Deeper reflectors have focal point of closer to buttom of reflector while shallow reflectors have focal point of closer to lens.
Most incandescent bulbs spread the light up to 300 degree while some LEDs spread up to 120 degree and that's why deeper reflectors are necessary for LEDs and thrower for smaller incandescent bulbs. Using large bulbs in large opening deep reflectors will waste some of 300 degree beam which is underneath the focal point and using LED in shallow reflector will waste some surface of reflector simply because there is no light beyond the 120 degree to reflect.

Finally got the time to sputter one. Sputtered it just enough to pretty much eliminate the donut hole. Can still barely see it but it's not noticeable unless you really look for it.

Of course there's a loss in throw but the beam looks much nicer now with a P7. Great reflector & I love it but is still not the answer for P7, although it is better. The P7 needs a big reflector for massive throw. However they're perform very well with single die LEDs.

I'm keeping my other one smooth. I'll be using the smooth for my P4 or maybe a Cree, throws very nice with the P4. Can't wait to try the sputtered one with the MC-E.

All beamshots with P7 at tightest focus.

And one more...
