Cree Q5 reflectors

[Zero_Enigma]

Ok not sure if I asked this before but may as well ask it to clear up some questions I have in this area. Thinking of ordering some of the IMS20 reflectors and/or Khotad reflectors of a member on CPF.

Now I'm not sure if the IMS20 and the Khatod reflectors work with the Cree Q5. Will they work with the Cree Q5 or any other Cree LED or do they only work with a certian few Cree models?

How are the beamshots with the Cree Q5 with those reflectors? Is there a pronouced square in the middle of the optic when you're throwing the light far?

Right now I only have L2 optics which work good on the SSC P4 LEDs I have. However the blue LuxIII LED seems to only want to give me the square die image when I use the L2 optics on it. I also get the square die using the L2 optics on the Cree Q5's.

Hi Zero
Do you need to use reflectors? With those you mentioned you will get dark rings in the beam.
There is a spot beam reflector used in the Scolo

Much better options with optics.

There is the standard Cree 8 deg optic for a nice spot beam -no artifacts.
The Carclo 10200 10.4 deg gives a smooth medium beam.
There are a few others as well.

Cheers
Dom

Dom,

I'll come right out and say it. I'm thinking of ordering some reflectors off PhotonFantic (sp??) a seller in the CPFMP.

That Carclo 10200 10.4degree is it for the SSC P4 or Cree? BTW that Cree 8 degree optic you mentioned, will that work with ANY Cree LED produced to date regardless of model?

I'm checking out the http://www.carclo-optics.co.uk/carclo-optics.home0.0.html right now.

EDIT:
Dom,

The reason I'm using reflectors is becauseI have heard they give the longest and brightest throw of light. I will be using the longest throwing light on the helmet as I do ride in some sketchy areas around here and take the wooded paths sometimes. I would like a strong, bright light that can throw a sharp bright light downrange so I can lamp up any sketchies hiding in the woods or pathways. I ride with both a barlight as well for close-mid range. I'd just like to scan downrange ahead of time in the pitch black woods. Also as a secondary use is because I do take on some fast rolling hills decents in my part of town on my return trips home.

Edit:

Dom.

What part number is that Cree 8 degree?

 

[Zero_Enigma]

Where can I get Carclo optics in Canada or the US of A? The manufactuer (sp?) site shows 50 count orders.

What part number is that Cree 8 degree?

Here $2.50 shipped from kai, was 10 for 10$ when I ordered but can't find that now.

Very nice optics.

Hi Zero
Yes -the Cree 8deg is very spotty and would be good for your purpose -i think DX also sell them.They are made for the 7079 XR-E series
http://www.cree.com/products/pdf/XLampXR-ESecondaryOptics.pdf

Don't know where you can get the Carclo -i got mine from Cutter.They are for the Cree as well but not as good a spot beam as you would like.

The Ledil ROCKET SS (for Cree) would be a good one as well -very nice beam -the only reason i haven't used these more is because they are 26mm diameter.
Brum seems to have run out of those but has some other type (LC1 -RS) that look good .Check out his groupbuy -i've bought stuff off him before -might get some of those myself

I also get lots of stuff from PhotonFanatic but all his stuff is for Seoul and Lux

The really good reflectors for Cree are very expensive ones from McGizmo.

I don't have my ruler or digicaliper or the numbers handy but 23.2mm I think is too large to fit in a 1in square aluminum tube. Gow is the beamshot on that optic? Can you take a pic of that if you own it? I prefer less spill and as much downrange light as possible.

Dimensions:
(Lens) Diameter: 18.3 cm (opening) 5.34 cm (LED), height: 13.5cm
(Holder) Diameter: 23.2 cm (opening) 10.6 cm (LED), height: 15.82cm

It will fit, an inch is 25.4mm.
For two-fifty you can evaluate it yourself and let us know what you think!

ps, beamshot on by dual bflex road page, below.

I'm talking inner diameter and not outer diameter. I just got my measurements on the tube ID.

So for a 1in aluminum square tube at Home Depot the ID is 22.80mm max tho I think 22.75mm allows for smooth in/out.

The OD is 0.9970

The holder is plastic, you can trim it to fit.

Argh my fundage on this is getting smaller. How much of the Kai 8 degree holder do you think you can take off? 1-1.5mm all around without effecting the holding?

Found it for you.

You could take the diameter down 3mm (1.5mm from each side) before you encounter problems.

Cool. I may order a couple to try the 8 degree. If I don't like it anyone up for optics I don't need? Also need to figure out a way to mount the holder onto the portable drill in a way that won't fly off so Ican spin it while pressed on the sandpaper.

When I trimmed down my 8 deg optic holder to fit inside my copperhead light, I just lightly clamped the base of the optic in a vice and ran a dremel tool around the outer edge of the holder to shave off enough material. It's not hard.

Ah. I did think of that way but thought the attaching to the portable drill then spinning it on the sand paper would igve a more even sanding then spot sanding. Both ways work.

I got an 8 degree rough, but hate it. Most of my lux 1's must use 6 degree smooth (dorcy excluded, which I gave away cause so wide angle), which offer a brighter light than the cree/seoul mod with 8 degree. So I don't get bumping up the lumens by 90% then lowering lux by an equal or greater amount by widening the optic. Lux of a cloudy day is supposed to be 30,000 (wiki) while the best lights only give 11,000 at 1 meter. Consider, also, I need 10 watt hour battery pack for every watt I run to get a full 10 hour work day, and one can only conclude that we have a long way to go to match daylight detail with any battery operated lamp when used for close work to illuminate detail.

radius squared so x lumens per 9 (3^20) verses x lumens per 16(4^2). so jumping 2 degrees from a 6 degree reflector dilutes light to give you 9/16 of the throw. Or 56% the brightness on spot you are looking.


I know bikers like it wide, so why not do two 6 degrees with option to angle inward as one beam or separate to up to 12 degree wide? Also, mixing a cool and warm led give wider range of color rendering.

While I feel strongly about real world need to keep optics narrow to improve lux to a cloudy day level, perhaps someone more knowledgeable can tell me if they have tried a 6 degree and not like it.
