Thread: Anyone tried the Z-led P4's ?

  1. #1

    Default Anyone tried the Z-led P4's ?

    Just found a new (to me) led that looks good from the data sheet.

    Seoul Z-Led P4, runs from 350ma to 1A and at 1A has 240lm output. Also has a forward voltage of under 4v so comparable to the 3w or a K2 electrically. They also appear to have the same star configuration and looks like they can use the same optics as a luxeon.

    Ive just ordred a couple to test so i'll find out soon if they can. If everything is as the data sheets say then a good upgrade to my 130lm white K2, almost double the light for the same in.

    Datasheet http://www.dotlight.de/datasheets/SeoulP4.pdf there if you want to check it out.

    I would already have built one, but my usual suppliers either don't carry it (hint hint, Tim ) or only have the lower bins.

    As soon as I get a decent one, I do intend on giving it a good workout.

    What would you use for optics for these? And how would you go about mounting them to a heatsink? Specifically Tim's 1-1/4" sink tube heatsink. I may have to buy one of these...

    if they do work in star format, then just like a normal lux

    until neo confirms this, it will be a mystery

    where would a guy go about getting a star board to mount one of these to? I've looked around...

    The one Im waiting for is already in a star format.

    Ive ordered it from dotlight in germany. http://www.dotlight.de/shop/product_...roducts_id/909

    If you want a blank star to mount your own emmitters on then you can pick them up on ebay such as here http://cgi.ebay.co.uk/Luxeon-K2-Alu-...QQcmdZViewItem another german firm.

    I've been looking at an asian reseller that has the U-bin z-power SSC leds, always wondering if its good or if its just an asian luxeon knockoff with boosted up spec sheets. (also wondering if I can trust the asian reseller himself)

    http://www.dealextreme.com/details.dx/sku.1445

    they also have cree brand luxeon shaped power leds in white that can go up to 100 lm at 350 mA. (altough I doubt they'd support up to 1 amp.)

    Marsupial, the Seoul Zled-P4 rank U is what I have coming to me from dotlight but that seller is cheaper so thanks for the link

    As for the Cree leds, well alot of the custom flashlight guys have been using them and having plenty of success. It was the CPF (Candle Power Forums) that put me onto the Seoul led in the first place. Saw them mentioned, read a few threads and noticed that dotlight who I get leds from anyway were stocking them. Couldnt really resist

    I would have tried a cree but they need their own optics and so far those Ive seen are bigger than the equivalent luxeon ones so Ive not bothered.

    At under $8 inc shipping I think that retailer is worth the risk. In fact I might just order a couple anyway once Ive tested the one I have coming. Can never have enough leds Besides Ive got loads of EL sabres I could convert.

    I'm seriously interested in whatever result you can post us... both at 1 amp and 350 miliamps.

    If brightness is increased, even with colored filters, I'd think of changing my 1W star/Os for those P4 U-bin under Corbin's driver at 350mA.


    But for now, I'll be moving in less then 3 months, so I start to stop ordering stuff as I'll be packing most everything soon. I'll mention it: I hate moving. but with the new place I'll have my own workroom.

    anyway, I hope those SSC leds makes good results.
