Thread: Commonly Used LED Emitter Index

    The apparently quick-and-dirty and forgettable portion of the OP post allocated to Nichia is quite appalling!
    I may sound disrespectful by saying this, and I understand that Craig may not yet have time to update this thread with more info… but I think this just doesn't do Nichia's LED justice, especially with the awesome Neutral White-producing 219 series LEDs!
    I got into CPF and into flashlight collection solely on the HighCRI merits of Nichia's 219 LEDs, on top of the hosts and flashlight designs! Nichia deserves more recognition than that little short paragraph for it, compared to all the CREEs above it.

    Cheers!

    Flashlights are very benevolent during night. One should carry a good flashlight with him/her. Information shared by you about flashlight is really benevolent and meritorious.

    What is the advantage of the new XM-L2 U3 bin over the U2? I want to upgrade a couple XM-L2 torches with warm tints. Should I wait till they start coming out, or just go for the upgrade now with current XM-L2?

    Each increase in bin usually gives you an average of about 7% increase in brightness. You may be waiting awhile for a warm tinted U3 bin. Warm tints are normally less bright, and are found in lower bins until the manufacturing process catches up.

    Right, I prefer a warm tint for better depth perception and color rendition to a washed out but ever so slightly brighter beam. My other light with a warm XM-L2 is plenty bright, its nice beam that is easy on the eyes is what I like about it the best.

    I may just get the current bin, the green hotspot and purple spill of the cool XM-L2s on the dimmer settings are killing me. The warm tints also tend to be perfect from hotspot to spill and at any brightness.

    It would be really useful to have a separate similar thread for high CRI emitters. Difficult to search for info on lights since often the same model has a choice of emitters. And people spell high=hi, add "-" between words, etc so searches are imprecise.

    This is the most useful thread on CPF, however i am afraid to report that Many image links have broken.
    A saloon chair has replaced LED pic on First page! Something sure is amiss!.

    Anyways I feel that an existing thread should be resurrected/ Repaired rather than making more new threads.

    After reading through this thread iv still got questions as a newbie.
    My main question is whats a good all round LED?
    Will an XM-L 2 be a good all rounder?
    Is there something far better than the XM-L2 ?

    I will be using a reasonable quality aspherical lens.

    Depends on how much battery you plan to power the light with. using 1 cell lithium, a cree XML HI v6 is now one of the best available. I don't know much about voltages or the control circuits that can mess with them, potentially allowing you to put an MT-G2 on a 1 cell AA or something.

    I'm a big fan of the xm-l2 LEDs.
    As an all around LED, they've worked well in my projects, both domed and dedomed. Warm and neutral whites in the higher CRI versions.
    Just my 2˘.

    Is there a thread that lists the flashlight model by which LED it uses?

    It would be nice to see every light that is made that uses say the XHP 35 HI LED, etc.

    Interesting that high CRI has nothing in common with LED emission temp. index:

    I would like to be know how to differentiate all the various LED, but the pictures on the first post by csshih does not seem to work and the link to the Emitter Index ( http://www.lumensreview.com/emitter_...er%20index.htm ) gives an error message.

    Is there some other list I could refer to? The best I was able to find at the moment is the FlashLight wiki, namely for Cree LED ( http://flashlightwiki.com/Cree ), but the pictures are not very clear/sharp.

    Thanks.
