    my new quad mc-e



    just a teaser for now, but I hope to test it out this week. It's fully assembled and functioning, I can honestly say it's the brightest LED light I've ever seen.

    The entire housing was cut on my friends manual mill, it took a few months of cutting a little at a time.

    I'm using 3 warm white, and 1 neutral white (left over), with boomerang SS reflectors. It's being driven by a hipflex and a 18v makita li-ion drill battery.

    I'll upload more pics tomorrow.

    My theory on the MC-Es is that more usable light output can be had with larger diameter optics. I built a single MC-E (running @ 1A) using the housing and optic from one of these DealExtreme E27 getups, but beforehand had tested out the beam pattern with the two different Boomerang optics for comparison. I know, I know, everyone is trying to make their lights smaller and lighter, but I am convinced that larger might be better. Once again, as stated in another thread, I am not an engineer.

    My dual MCE ended in the spare parts bin. I only kept the MCE to power a triple XPG w/ 35mm optics and now the trail lights up!

    I still need to trim some depth from the rear housing cover. I'm pretty sure I can lose 10mm of depth there. We are also going to try to create a little more surface area in the fins. I'm very impressed with the output of this thing, it's a wide spot that gives a huge field of view but still has plenty of throw.

    I really like the Frean narrow reflectors for the MCE. My fav light (so far) is 2 narrow Freans on the head, and a MCE with an LM1 optic on the bars. This is a great combo. I did like the 3 MCE's with Boom reflectors as a bar light too. Boom's have a nice "flashlight" type of pattern. Very nice work so far; I think you need more finning for sure though. James

    my camera doesn't have a real manual mode, so these exposure times are not all the same, but I did what I could with it. The iblaast2 has a blueish hot spot that stands out against the quad. The quad has a wonderful deep yellowish tint, that really makes everything stand out.

    Nice work, what is the heat transfer currently like? - just thinking if there would be a nice way to force air through the fins, I'm not sure how much airflow you'd currently get?

    RT...when posting photos of builds it's really a good idea to include an object ( like a battery ) for us folks as a point of reference so we can judge the size better. By the way, nice build.

    Cat-man-do, you could use the other bike light (I-Blaast 2) as a reference, it is MR-16 sized, ie; 50mm or 2 inches in diameter.
    Cheers, Digger.

    Hi,

    couple questions:
    what kind of driver do you use?
    how are mce's connected inner and to other mce's ?
    what battery do you use?
