    My mini culite

    My first little light. It still needs a optic but here in Cape Town in SA its bit harder to get than expected.

    I got a XPE Q5 and the CuLite jumped to mind but I thought lets make it smaller. So i used a 15mm pipe in place of 22mm. This meant that I have to find or make a compact driver. So I made it. Here is the specs on it


    XPE Q5 on 12.5mm board
    10mm long alu lug to fit pipe
    15mm pipe coupler
    15mm pipe
    15mm end cap

    driver:
    zxld1360 led buck driver
    resistor R160 1206 give a 625mA output(measured 610mA)
    diode
    cap 4.7uF 1206
    100uH inductor


    Building the driver without a pcb was tuff, but I wanted it small. It made it also structual weak. After I tested that all was working I used some thermal epoxy blob to make it solid.

    I have had it run a few minutes and just gets warm not even hot. Had a short run other night on bike and while riding it stay cool to the touch.

    Here is some pics:
    First up is complete driver in testing stage:


    then I mod it to be close to inductor and make it more compact:


    Here is the led glued to the alu piece and the driver epoxy covered:


    Just before I closed it:




    The wire out the end cap:


    The is it 90% closed up along side a AA battery:


    99% finish. Just needs optic inside

    Brilliant. It's great to see the CuLite concept being pushed even further and people coming up with their own innovative solution to things. I can't wait to see the completed light and I hope it meets your needs.

    Nice. Harder to blaze the trail. What optics are you trying to get? Importation issues?

    I looking to get a ledil Lisa2 RS from farnell thought a place here in sa but they dont have stock. Importing is not really a problem but shipping cost for a lens is. ex cutter $2 for lens and $10 shipping. I feel it is not worth it.

    I don't know if this helps or not but Digi-Key sell Ledil optics. They list the Lisa but not the Lisa 2. They have an international website with an SA option but ship from the USA I believe.

    I am in the UK and have ordered from them in the past but I had to put in an order over 50 to get free shipping. Almost unbelievably my order arrived a day later!! (shipped from the USA).

    Getting all the parts together from suppliers all around the world is one of the biggest challenges we face unfortunately.

    There is a guy called Brum I think who supplies optics and other parts on CPF I believe. I have never ordered from him but maybe someone here can point you in his direction.
