    Default FS - Onion Rings (SF A2 LED rings)

    Read how the project started here!

    CLICK HERE TO JUMP DIRECTLY TO ORDER LIST & UPDATES.

    Hello guys,
    I am finally making these available. Please read and read carefully, before you take the plunge.
    For this reason, I am posting the user instructions first then followed by the actual sales contents.

    Onion Ring User Instructions



    Before performing the task, please ensure that you are wearing a grounded anti-static wrist strap to prevent damage from the electronic components.
    The 5mm LED has no ESD protection. Here's a howto.

    Inspect Onion Rings

    1 - Check the springs are in shape and the DIP connectors are straight. Refer to pictures below.

    Preparing the LEDs.
    1 - Trim the leads to 4mm. Usually, there will be a stopper in the way, remove the stoppers with a file. Thick leads will damage the socket.
    Some leads are thicker than normal, if so, thin the leads. A Dremel with sanding disc will work well.




    2 - Remove base/skirt with a file. The easiest way is to insert the LED into a drill chuck and file away




    The LEDs should have a smooth body without the protruding base/skirt.




    And a crude sample of a LED from beginning of the project



    Preparing the SF A2 head
    Dust is your main enemy, start by cleaning your work area. Once it's clean, clean your SF A2 especially the bezel head area. You don't want anything to fall inside the reflector area because it's hard to remove it afterwards. Remove the original Surefire A2 LED ring by disassembling the three screws with a small Philips screwdriver. Keep the screws in a safe location. Do not lose them!

    You should recycle the Onion Ring packaging by reusing it for storing the Surefire A2 LED ring. Keep the item safe, you will not need it for the rest of the installation.

    Preparing the Onion Ring
    1 - Adjusting the Brightness.
    The surface mount trimpot has an arrow pointer, you may need a loupe if vision is not perfect. It will arrive in medium setting(12 o'clock) as a default. Each LEDs will be driven at 10-15mA.


    2 - Minimum brightness setting is at 7 o'clock. Each LEDs will be driven at 3-5mA.


    3 - Maximum brightness setting is at 3 o'clock. Each LEDs will be driven at 32-38mA.



    Adjust brightness sparingly and only when needed. The trimpot is not a regular stereo adjstment knob, it will not last many cycles.


    4. Installing the LEDs.
    When the socket is at 12 o'clock, positive is on the left and negative on the right





    Installing the Onion Ring
    1 - Insert the Onion Ring in to the A2 head. Position a screw in to the correct slot as pictured (other slots may not work)


    Important!

    2 - Hold the screwdriver as upright as possible and turn slowly and lightly clockwise. Do not use any force, if you feel any resistance, remove the screw and try again.

    It's easy to strip the thread in the A2 head as the metal is soft. So install the screw slowly and carefully. We only need 1 screw for now. Reinstall the Surefire MA02 bulb then the head. Check if the LED brightness is right.

    If adjustment is required, remove everything and adjust the trimpot.

    3 - When you are done with the adjustments, reinstall the second and third screw.


    The screw holes might not align properly. Loosen the first screw by 2 to 3 turns. Then try installing the second and third screw. Finally tighten the screws one by one in small steps.

    4 - Due to the design(more like lack of) of the pcb slots, the screw does not go all the way in. So stop turning once you feel resistance.


    5 - The Onion Ring does not need all screws to function, you can leave the two screws out but keep them in a safe place. Do not lose them!

    Default Re: FS - Onion Rings (SF A2 LED rings)

    Please note the two issues below before placing your order
    1) As hard as I try to align the holes on the circuit board to the Surefire A2 head, it is still not perfect.
    So you might not be able fit all three screws but the Onion Ring will operate with a single screw in the right slot.
    This will not affect the reliability or operation of the light.

    2) The Onion Ring uses DIP sockets, the LEDs might dislodge from the socket if subjected to shock. ie dropping the flashlight head first on the ground.

    If you do not understand or agree to the terms above please do not place order.

    All prices in USD.

    Base Price
    Onion Ring(no LEDs) - $21.00

    5mm LEDs 20 Degrees, 3xLEDs per pack


    Yellow_____30,000mcd__$1.20pk

    Red _______25,000mcd__$1.20pk
    Cree Green 20,000mcd__$0.90pk
    Cyan ______ 6,000mcd__$0.60pk
    Cree Blue__ 5,000mcd__$0.90pk
    Cool White _____30,000mcd__$1.50pk
    Warm White 17,000mcd 3000-3300K $1.20pk

    UV 380-385nm $3.90pk

    Shipping & Packaging

    All shot at ISO800, f/2.0, 1/100s (20mA) (Except for last picture)


    Yellow ------------------------------ Amber


    Red (Current Stock is much better, new pics coming soon)
    Not very exciting.


    Green (Not CREE) ------------------------------- SF A2 Nichia Green
    Much brighter and smoother than the Green Nichia.


    Cyan -------------------------------- Blue ( Not CREE)
    For some reasons, my camera could not capture cyan and blue accurately.
    The colors are a bit off compared to what I saw.



    Warm White --------------------------- Nichia GS


    White --------------------------------- Nichia GS


    White -------------------------------- Nichia GS


    Warm white -------------------------- Nichia GS
    The 3x00k warm white is very interesting. It has a layer of yellow phosphor
    which is evenly applied, it makes the beam very smooth and pleasing. Unlike
    cooler White LEDs, it does not have a bluish center. The color is even from
    the center to the outer ring. Not quite sure about the CRI number, I wouldn't
    expect anything decent.


    Power Star Nichia High CRI 350mA (exposure increased by +ev 0.67) NOT FOR SALE

    I'd be a definite for two if possible, or one if that's the limit. Depending on what's available for LED packs, I'd be interested in amber, UV or possibly red...or possibly others, depending on what rabbits come out of, err, the Koala's hat.
