    New XML Reflectors

    FYI, got an email. Looks like Cutter has some new XML optics/reflectors.

    One of them shows 80mm diameter. WOW, no problems with surface area on that light housing!
    FastMatt is an oxymoron!

    Wonder who the manufacturer is for the reflectors? They are huge. The also look pretty short and squatty to be good throwers.

    Wonder why they did a round opening in one and a hexagon opening in the other? Why not square?

    Not too excited.

    48mm tall doesn't seem short? The first one is claiming better than a 9deg total beam which seems pretty good.

    How about the little XML- specific optics?

    The hexagon opening is 20mm, thus the whole star fits into it. Guess that's the reason.

    I don't really fancy them being that big. No way to make a nice and small build using them...

    big ? 16mm is smaller then a 20mm star !?

    take a look at a pico . It has more heat then lumen.
    What I mean, is, it gets hot fast, and needs to throttle down the lumen.

    Smaller optics , are also less efficient, and show color variations more (ugly).

    my preference for 2/3 xml power no smaller then 1" (25mm)
    for any other / higher power , 1.25"- 2" , for each.
    If you want an idea of size/ratio to efficiency, take a look at the custom
    Hella lights. for example the FF series .
    Hella designed some of the world most efficient reflectors .
    And those are definitely not the smallest.

    the 7D reflector, looks to be a very good one.
    take a look at the size 45mm , MS -> ~35mm

    oh, thanks for the post, options are good,
    availability, even better.

    cheers, Rob

    Yep, those reflectors are huge!! Looks like the are from China, found the exact same ones on Alibaba. I am just not an optics kind of guy for some reason.

    Yes, I got really excited when I got Cutters email and saw the claimed angles, but then I saw their size so moved on very quickly.

    Would make really good garden lights though for lighting up the gum trees in my backyard

    Really?

    That 9deg total beam width 35mm optic that is under 18mm deep seems like a great little mr11 sized optic. You could make a pretty compact housing for something like that.

    I was talking about the reflectors, not the optics. Every time I have been excited about claimed angles with optics and have got my hands on them, I have been disappointed. I didn't even look at them this time

    Of the 5 different light designs I've built, the three with optics are the ones collecting dust, sold to others, or junked. Reflectors produce a beam more to my liking. I am doing another light with a pair of Cute SS triples. Looks OK in the shop, but it will take a ride to tell for sure if it is nice.

    More likely tormenting the Wallabies in the gum trees at 130 meters.

    I am with Scar and Emu here not going to get excited till either I have some to try or some of you closer to Cutters get some and try .

    but at least something is happening from someone in the optics world .


    also looks to be a few new ones going up on the new Ledil site
