ROP with 8.3 mm opening...

[Mjolnir]

I recently built an ROP using this reflector. While the bulb itself fits through, the opening seems to prevent it from going as far out into the reflector as it normally could. The ROP also has far less throw than I had expected based on beamshots posted here by various people. I realize that they are using different reflectors, but they are all similar in size. I suppose that I could have simply underestimated the hotspot size... However, I have no way to determine if the bulb is focusing as well as it could in the reflector.
Does anyone have any experience with using the reflector with the smaller opening vs. the larger one? Could the reflector with the smaller opening reduce throw? It is MOP, but I was under the impression that a textured reflector wouldn't reduce throw all that much (especially since the reflector is so large).
My malkoff maglite easily outthrows the low bulb, and probably the high bulb as well.

If your reflector has flat area at bottom (around opening) of reflector, then you picked wrong reflector for incan.
Incand reflectors regardless of opening size should not have any flat area.

When you use the proper type reflector the ones with small holes typically throw better.

I have a few of the reflectors you are using and I also have many of FiveMega's reflectors. The problem you are running into is the ROP HI potted bulb can not get far enough into the reflector you are using. Kai used to sell this http://www.kaidomain.com/ProductDetails.aspx?ProductId=1661 bi-pin socket. This socket differs from the FiveMega's http://www.candlepowerforums.com/vb/showthread.php?t=179891 bi-pin socket. Notice that FiveMega's bi-pin socket is slightly recessed by maybe 2 mm? I suspect that a G4 bulb and FiveMega's bi-pin socket more closely approximates the positioning of a potted bulb. I have many of FiveMega's bi-pin sockets and they work great. Kai used to sell a G4 bulb called KD773U that worked very well with his reflector and his bi-pin socket. Nice solid med to large hot spot. I am also able to use a AW1111 with Kia's reflector and bi-pin socket with good results. It generates a smaller hot spot and whiter than the KD773U. If you purchase one of FiveMega's bi-pin socket and mount a AW1111 on it 2 mm high it will work with Kia's reflector. Now that being said I like FiveMega's reflectors better than the Kai reflector you linked above. The kai reflector has a very rough orange peal coating and is not as good as FiveMega's MOP reflectors in removing artifacts.

Happy Mods.

the Kia's reflector.....

Kia's reflectors with the flat bottom will produce the most artifacts in my experience.The one's with no flat spot aren't as nearly as bad.Frosting the bulbs also will make a big difference in beam quality.

For some reason the product picture shows that there is a flat spot at the bottom of the reflector, when in fact the reflector actually has no flat area. It tapers right down to the hole.

Do you own any other hot-wires that you can compare it to or are you basing your thoughts off of beamshots alone? The reason I ask is that perhaps you're expecting more that you should. It's a great combination with reasonable run-time but unless the reflector is heavily textured, like a Surefire, then you're not going to have a smooth, perfect beam. If you do indeed have a "hot-spot" then you at least know the light is focused. If it's not focused you'll have a dark void in the center of the beam. If you posted some of your own beamshots on a flat surface like a wall or garage door, we'd be able to verify if what you're seeing is correct.

It may be that the reflector inhibits it a little, and it should be slightly more focused. The hotspot is smallest when the bulb is farthest out into the reflector, but I doubt that that is the optimum focus point (since the reflector is not designed specifically for the bulb). I was thinking that if the bulb went a little farther out, the hotspot would be slightly more focused. However, there is a definite hotspot, and no dark center. Perhaps I am just overestimating the throw that an ROP should have.

Sounds like maybe the output is sub par. Whats the powersource?

 

[Mjolnir]

It is running on 2 18650's. I usually just run the low bulb, since the high takes a few clicks to start. I realize that Lithium ion cells might sacrifice a little output, but it is still very bright. Comparing it to other people's beamshots (for brightness) doesn't really make sense, since beamshots rarely illustrate the brightness accurately. I have a feeling it could focus slightly more, but I also might have underestimated the size of the hotspot.
The high bulb seems to have similar throw to my 3D Maglite with Malkoff droping, but it lights up a much larger area, and instead of white light, there is a nice warm incandescent beam that shows colors much better.

A high quality LOP reflector will give a hotspot diameter of between 6 to 9 inches at a distance of 20 feet depending on who's reflector you use.

Any suggestions where to get appropriate reflectors? I'm running into the same problem with my KD reflector.

Try Custom B/S/T, look for threads by Fivemega.

LumenHound-you should check the link you gave-when I clicked on it I got a screen with the message "Reported Attack Site!".

 

[LumenHound]

Works fine for me.

Do you see theledguy.chainreactionweb.com/product_info.php?products_id=780 when you mouse over the link?

 

[ANDREAS FERRARI]

That's what I see.I clicked again and the warning popped-up again.I didn't end up at the Sandwich Shoppe.Punched Sandwich Shoppe into Google and got the same warning!!! I haven't shopped there in several months-is something going on that I don't know about?

 

[LumenHound]

The problem is with the server.

Wayne posted about it yesterday in this thread.

 

[ANDREAS FERRARI]

Thanks for the update-I haven't shopped there in a while but it is one of my top 3 CPF related sites-I highly recommend it to any newbies lurking.And no-you don't buy that "kind" of sandwich there.

These new Ver2 Deep M*G Reflectors have a 8.5 mm opening.
