    Hey guys- just a warning on over applying AS-5 to p60 modules.

    I guess some creeped into the threads of my Linger module that Big C tested and caused it to dim n flicker. I sent it back to NB thinking the driver was bad.

    I had it slathered pretty good - guess its a bad idea to go crazy with it.

    AS5 is both non conductive and slightly capacitive. It's also only useful between very tight, almost microscopic gaps. If you need to fill a gap thicker than a sheet of paper you need to use a metal tape or foil of some kind + the thermal grease.

    ^^ word.

    If you look on some of the earlier pages in this thread Big C
    used quite a lot on some of the modules he was testing and
    did get improved results. I did the same but it eventually migrated
    to the threads on the pill and caused my drop-in to flicker and
    dim. just a smidge on the outside of the copper tape is probably
    best.

    They looked like rectangular shape to me, not square
    Just kidding.

    Corvette6769,
    The original version of PLI was also in the $57 range, but later on I lowered the price of PLI due to the camo color. Back then MC-E costs less than SST-50, the body of PLI also costs less than P-rocket. If it costs me more on this new product why should I sell it for less profit? I'm not in the business for charity, and I'm certainly not wealthy enough to do that. Just try to have my ends meet each day.

    Some people like 5700k color, others like 6500k,3000k and 4500k. Not possible for me to make P-Rocket in all different color range and have everyone pleased. Like you said, you can find lights on DX cheaper and brighter, which is great. But Shiningbeam.com is not DX, we are an American company and we can't survive on 10% profit like the retailers do in China. If you are not happy with our products' quality and price, just simply don't buy them.

    Hi BigC,

    Are you still doing this type of testing?

    Have you tested any XML U2 maglites? If so what is roughly the output @ 3A?

    Thanks
    In Him (Jesus Christ) was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not.

    Seems this isn't being updated any more. Sadly. Maybe it is time to un-pin it?
    Note to self, turn off flashlight when a plane is over head. Don't want them trying to land.

    As someone who recently purchased a used Surefire LX2, this makes me very happy. Looks like approx 240 lumens of output (initially) from a light rated for 200 lumens.

    The most impressive thing is that Surefire LX2 you can put a L1 XR-E bezel on it. Run a factory IMR 16650 cell and you will get close to 13.5K lux or so and about 300 real out the front lumens. That was my favorate Lego. Not very efficient since its direct drive and 1.6~1.8A but soo much lux from small bezel is cool.

    I believe this is the brightest LED light on Mag C. It doesn't throw as far as the SSR-50, but it looked to me about 1.5-2x the OTF lumens over the SSR-50/5Amp light, so I think it's going to be >1500 OTF at least
    I think so

    I am not having any luck searching for lumen readings for the 2014 Fenix E05 aluminum, the Olight i3s, and the Thrunite Ti3 Titanium
    can you link me to actual lumen tests for those 3 lights please? Im looking to see the readings with standard Duracel aaa alkaline batteries
    thanks!

    Technically it depends on how you measure it. Sphere readings like this won't test for lux, but lumens can be measured the same way lux is, if you basically average the intensity and size. Technically it is more accurate to do sphere but 2dimensional readings for lumens are possible. To save time, I believe ansi uses that measurement, not a sphere.

    I know the haters gonna start, but lumens and lux are essentially the same thing without being related at all.
    Because it is the same thing, you can take it and measure it using the same tool. Different ways of measuring lumens greatly distorts the numbers, which are further distorted by atmosphere. Some lights are theoretically measured based on LED since measuring takes too much time.
    Be the light.

    Ansi uses lux, because that is what the measurement is .... at what distance can you achieve a certain lux value. Sphere testing of a flashlight is great for specs, but not terribly useful on its own for a flashlight.

    - Are haters knowledgeable people?
    - You can't use the same tool. One requires a meter to measure the amount of light in a defined area. One require the amount of light in a defined area AND a precision method to take multiple measurements over a large spherical surface. It's like saying you can measure speed with a stop-watch ... or with a tape measure. Of course you need both to measure speed.
    - Different ways of measuring lumens DOES NOT distort the numbers. There are right ways, and wrong ways, and numbers are not distorted, they are right or wrong ... and not impacted by the atmosphere unless foggy or polluted
    - Lux and Lumens are about the same as mass and density ... i.e. not at all really.

    ??????? Whoa!!! Is this a new science? Better contact Cree, Osram, Phillips and etc., and let them know they are all doing it wrong.

    It's like talking to college kids. You guys completely agree with the truth in my comment, but don't know how to read it in a way you understand. Sorry we are having a hard time communicating. If I make some videos, I'll show you what I mean.

    First quote, then wtf are ansi 'lumens', and for the rest, try reading my comment slowly, and don't skip over major parts of the sentences that you completely over-elaborated on and went on and on to take a couple hours explaining what took me 5 seconds.

    Further the "new science" is called common sense, you take light-all-over-the-place, and turn it into an average, and bam, one unit to another. It's like taking mass, and roughly estimating density based on knowledge the object is spherical and how much pressure is on the ground the object is sitting on.

    And yes, my point well proven, haters weren't smart this time.


    Please stop being so ridiculously negative in your reaction to my comments. It's become an extreme nuisance.

    - As you have stated, lux and lumens ARE NOT the same thing just like mass and density are not. One is a base unit, one is not and you cannot convert from one to the other without a ton of other knowledge.

    For your knowledge, which appears to be lacking, the ANSI FL1 standard, which is for flashlights uses BOTH lumens in an integrating sphere and beam distance which is based on at what distance is the lux at a given standard. There is not magic and knowing one provides you with no knowledge for the other.
