    Convoy S2+ measurements (7135*8 3B)

    Yes,.. results I get measuring output should be OK, but it is the color temp I have no proper instrumentation, so really I should edit my post and just delete the Kelvin data. I have 2 more samples of these lights in transit to me now. One from the Simon/AliExpress site and other from...

    Convoy S2+ measurements (7135*8 3B)

    For what it is worth I just took delivery on the 18350 version from Banggood. My testing confirms that something is a little off with the Kelvin specs on these lights, on the XML2-U2 in my sample, just as maukka noticed the actual temp is more like the next emitter down the ladder, in this...

    Zebralight SC600 MKIII HI BUY IT!

    That's exactly it. I actually logged into my account over there at Zebra and started to write the first few sentences of a request for an RMA and got this weird little 'creepy' feeling, so I bailed out on finishing the process. I will feel much better just selling it. And anyway, maybe if no...

    Zebralight SC600 MKIII HI BUY IT!

    Well, I do not feel this is a fair way to do business. The agreement on the purchase is that it can be retuned or exchanged if there is an issue with the product.. There is no issue here, the light is exactly as represented and well within spec. I am an experienced user, I knew what I was...

    how much brighter can a led get?

    Yes, you are correct,.. I finger flubbed the "s" there and the plural is a source of confusion. (good eyes, +1 point for you !..) That's what's wrong with plain text language in discussion of these matters. I tested the waters in my last post and included a little math. When I first saw...

    how much brighter can a led get?

    Well, right. Again I will try to draw the conversation back to my understanding of the OPs original question "how much brighter can a led get" which i admit, I personally understand to mean that he really meant "how much more (radiant energy) can an led emit" Unfortunately my understanding...

    how much brighter can a led get?

    Please re-read my answer carefully.. You will see that I covered the issue that he asked 2 questions, not one, and I selected and responded to the question posed in the title. I will stand by my answer. He asked "how much brighter can an LED get".. the answer is that there is no limit. His...

    how much brighter can a led get?

    Upon rereading all this, I see that the OP asked two different questions, so I will address one of them (the other is a simple energy units conversion question that is really not that interesting anyway..:rolleyes: If I understand your question to be *exactly* in your title " how much brighter...
