    Home made LED

    posted by caver68 on 02/13/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    - Good mode groups which can be disabled in-situ via the on/off switch. - LED out is actually easy to spot and to solder to though there is a neat by pass with the +ve by taking the LED out straight from the back. - Draws 1050mA across the voltage range. - ...
    Cons:
    Low mode is 5% not 10%. 10% would be more useful to me but this is a minor point.

    Best driver for use with 1 lithium cell

    posted by Andrej86 on 12/24/2011 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Probably the best linear / PWM driver board (on DX) for LEDs if it's driven from 1 lihium cell. The PCB design is great and allows you to add additional AMC7135 chip to increase output current to around 1.4A. Could be upgraded even to a 2.8A output if you s...
    Cons:
    I don't see any major flaws. It is linear type driver but this is only in high mode so it think efficiency is not a big problem...

    Versatile board with expansion options

    posted by ledsmoke on 12/23/2011 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    Does as it is supposed to and delivers a constant current of 1A over very nearly the whole period of battery life (18650 batt.) Has optional mode groups selection that I like because I dont like to go through the blinky modes for 99,9% of the times when I ...
    Cons:
    Hard to say since it works flawlessly even with my little "hack". Can hardly complain about the size since it should ...

    Great little PCB for super price!

    posted by ollyk22 on 06/10/2011 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    Allows you to run LED without strobe modes Cool running runs to stated specs i.e. supplies 1 amp @ 3.7V
    Cons:
    Low mode is too low Could do with more light levels but kept to different group maybe

    best board i found so far

    posted by JimmiR on 05/07/2011 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    good product for the item i use it for. the extra place for a amc7135 to boost it to 1400mA. it really does what the specs say it will do. the tiny13a IC is nice programmed and will remember the last use setting.
    Cons:
    you have to know where you put your iron for the wires. But if you go find a datasheet on amc7135, it is not so hard to under...

    works great

    posted by dakabo on 11/25/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    multible gruops. i bought this because of the constant current and the capability of not strobe/sos. but i have it if i need it. the pcb is soldered really good and works great. low-med-high mode is: 30mA-300mA-1050mA. the acm7135 chips needs 120mV to regu...
    Cons:
    only that there is no capacitor for the atmel pic so if the battery is disconnected for just a micro second, it will change mod...

    Good board, works as advertised/

    posted by David18 on 10/16/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    Multi-modes in multiple groups. Easy to use interface. I used it with P60 set (SKU 5937) and Q5-WC emitter (SKU 11022) in a WF-504B (SKU 24200).
    Cons:
    No instructions or documentation provided but can be found online. Soldering a little difficult due to small size of pads. Need...

    Love it!

    posted by technicc on 03/21/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    - very small size, fits pretty much anywhere - quality looks good - plenty of modes, police strobe is very nice (maybe just a tad too slow) - gives 1050 - 320 - 75 mA (Hi-Md-Lo) - fits in X2000 :) - has mode memory (but I don't find that particularly u...
    Cons:
    - doesn't switch modes if left turned-on more than 2 seconds -> when you tap the switch, it stays on the same mode, so you need...
