    Arrow Which is better? COB, CREE XP-L V6 or XHP70.2 LEDs

    Which is better? COB, CREE XP-L V6 or XHP70.2 LEDs

    What are the best LEDs available today in order?

    I'm new to really paying attention to flashlights myself, so I pulled up some PDFs, to see if I could figure it out.

    First, let's get some tedious pedantry out of the way. A COB (chip on board), is different from the other two. Where the XP-L and the XHP are single LED emitters, the COB is a group of emitters, stuck together on one board. You can have a COB that's made with XP-Ls, or XHPs, but you really can't compare the three of them on an equal basis.

    I'm going to link to the two PDFs that I found. Both are from CREE, I may be in a "gray area", forum-rules-wise, but they're for information purposes.

    https://www.cree.com/led-components/...nts/ds-XPL.pdf

    https://www.cree.com/led-components/.../ds-XHP702.pdf

    If you read them, you may find your eyes glazing over, like mine did!

    Near as I can tell, the XHPs are brighter, as in, they put out more Lumens. You have a lot (a lot!) of choices of how "white" or how "yellow" those Lumens look.

    If I know anything from other gear-related forums, there is no such thing as an objective "best". If you're looking at the LED as the start of buying or building a light, I would argue that there are many other more important factors than the alphabet soup on the emitter. These include, but may not be limited to:

    Cost
    Size
    Weight
    Body material
    IPX rating (dust and water "proofness")
    Carry method (pocket clip, belt holster, sling)
    Battery life
    Battery type
    "Throw" or "flood", or a little bit of both?

    And, if you're secretly an engineer, and you're just trying to get a feel for what CPF considers the "best", then I'm just gonna go chew on my foot, for a little bit longer.

    I was looking for the latest, brightest, most energy efficient Cree LEDs.

    I already took into consideration all the other criteria you listed, but I donít know how to compare the LEDs which are basically the heart and engine of every flashlight.

    I ended up purchasing a Zebra light, but canít figure-out if it came with the latest, brightest most efficient LED. I am sure Cree LEDs can be graded by this criteria. And I was also looking for an LED with a high CRI.

    I probably made the right choice, but it seem Cree ought to produce a comparison chart that would help consumers figure out the difference between their LEDs.

    Obviously, everything being equal the higher K, cooler lights will put out more light, more efficiently. However, every LED with a high K rating should have a corresponding warmer, lower K LED.

    So, to make it simple I was looking for the order of Cree LEDs by cost.

    Which is better? n.a. V8 engine, Turbo diesel or an inline 4 with a Turbo?

    Answer - depends entirely on the situation
    I'm as much Magaholic as flashaholic

    Well, from what I've learned on here, that's just half of it!

    You also have to look at the driver.......the volts and driving amps........& what type of battery you're using....not all 18650s are made the same....size of the LED.....how hard can it be driven.............then temperature/temperature control.....& even more stuff. ALL that + the LED comes together to make the flashlight what it is.
