    Cree Q5 triple optics beam shots

    Hi -just a couple of beam shots of different optics and emitters
    Had been waiting 6 months for these Carclo optics for Cree emitters to arrive -am very impressed with them.

    I couldn't fit the optic holders into the housing -so the optics are actually sitting on the dome of the emitters - still seems to work alright even if the focus is not 100%

    All beam pix are with triple emitters at 1Amp -approx 50ft to car.

    1) Control

    2) Cree Q5 & Carclo 10.4deg 20mm optics

    3) Seoul 10deg 20mm optics (my "old" light)

    4) Seoul 10deg mini triple optics

    5) Seoul 25deg mini triple optics

    6) Carclo 10.4deg mini triple 25deg mini triple 10deg
    Khatod 10deg









    Should you want to view bigger photos or download them

    I find the best way to see the difference between beams is to load them into Picasa and scroll thru them

    Cheers

    Sorry if I ask silly questions...I am reading all the LED posts just trying to educate myself. I have seen the DIY lights where the LEDs mount individually behind each separate optic or reflector in square tubing.

    What holds the three LEDs in the right position behind the optics? Or is that part of the optics themselves?

    Since you mentioned they did not fit in the housing, I was trying to picture that.

    I like the round shape. Seems like it would be easy to find round aluminum tubing to fit this to.

    Hi Mtroy
    Most optics have holders that align the emitter -usually you have to grind a bit of the back of the holder to give clearance for your wires.
    Some optics will align with no holder -the opening in the back of the optic will be a near fit over the emitter dome.
    Thats how i did the Carclo one - it isn't perfect -the housings were meant for other optics and reflectors.

    Most people who DIY go with the square Al tube because the square optics fit well in them and is easier/neater final side by side assembley -but i'm sure you could find some suitable round Al tube if you wanted to go that way -

    Could bind them into a triangle shape to make a more compact housing.

    Cheers

    Nice work Dom, thanks for sharing! You're getting quite a collection of emitters and optics / reflectors now!

    I have always loved the smoothness and quality of the beam produced by Carclo optics.

    I wouldnít be concerned about not being able to use holders, Carclo optics always seem to be a good fit over emitter domes, and it looks like the phosphor is visibly even around the optic. I know itís a pain to photograph emitters as you see them!

    Dave.

    Thanks Dave
    For the amount of optics i've bought lately -i think i could have got a Lupine
    The Carclo certainly is a nice optic -pretty hard to get a good beam on a bike using Crees.

    This particular optic is meant to sit about 1mm above the dome ring when using the holder -but as i have it now,it is sitting right over the ring,almost touching the base of the emitter.

    Cheers

    Sorry Msxtr -slip of the finger -i fixed it up.

    Are you saying the light seems similar?
    Yes -they are close -but i think the Seoul still has the edge.
    They are getting better all the time -and quickly at that!

    Cheers

    Hi MSXTR
    I have tried the Q2 ,Q4 and Q5 side by side -and the Q5 is definitely brighter than the others.

    The Q2 is WC tint (white)
    The Q4 is WH tint (neutral white)
    The Q5 is WG tint (cool white)

    I "think" they are the right desciptions for the tints.

    But there is a BIG color difference from a Q2 WC to the Q5 WG.

    As far as i've heard -DX is selling the real deal.

    I got mine from Cutters - would have preferred a WC tint -but is not available.

    Cheers

    Hi MSXTR

    That looks about the right color i get as well when i compare a DX Q2 to a Q5
    You can see the bigger hotspot of the Q5 -so it is brighter.

    You would notice the overall brightness difference using different optics or reflectors.
    When using an McR 19-XR reflector the color seems to change a bit.

    If you had a Q5 WC tint -you would REALLY notice the difference.

    I got an email from Cutter the other day saying he had Q5 WC now
    I think i will get some.

    QUOTE:
    We are currently stocking the most recent releases from Cree which include
    Q5 bins max 114 Lumens at 350mA or 256 lumens at 1 amp
    WC tint
    WG Tint
    WH tint

    END QUOTE

    Cheers

    Hi, poobardog Thanks again for all

    Yes, I see that hot spot of the Q5 led are more big than the P4 version, but I like more the P4 tint.

    Here I put another beamshot with a Q5 led but with a Mobdar optic, look


    Mobdar optic 36mm of diameter





    See you the great difference with the previous beamshots, with this optic are more biggest the hot spot, but the tint color are equal.
