    - 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. - Very small package size Low mode is 5% not 10%. 10% would be more useful to me but this is a minor ...

    True linear current regulation (thanks to AMC7135 chip) Maximum LED performance Well built Easy to install Easy to disable annoying flash modes without soldering No transparent information about LED +/- soldering pads. It will give the maximum performance for the LED, because it's linear current regulator. The Cree datasheet said, the lower current ... Read more

    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 stack additional 4 AMC7135 chips onto the original 4. Has many modes and a few intuitive functions.... Read more

    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 need a flashlight. Seems well soldered and the layout is simple enough that I was able to put 1... Read more

    Allows you to run LED without strobe modes Cool running runs to stated specs i.e. supplies 1 amp @ 3.7V Low mode is too low Could do with more light levels but kept to different group maybe Great little board. Not for a total beginner but if determined things can be worked out with little knowledge. Wish there was a data sheet available! I am not sure ... Read more

    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. 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 understand. waffeling ... Read more

    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 regulate the current and have overtemp protection. only that there is no capacitor for the atmel pic ...

    -No strobe! (if you're in the right group) -Tons of modes -Different mode groups -Extremely dim low -Maximum strength high -Mode memory -Hard to install -No directions -Slightly complicated -You have to turn it off while the led is actually illuminated to switch modes or it restarts the mode setting The strobe and sos modes on my akoray k-109 were annoying,...

    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). No instructions or documentation provided but can be found online. Soldering a little difficult due to small size of pads. Needed a little Dremel work to fit in SKU 5937 but that was easy and I did not have ... Read more

    - 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 useful) - has low voltage alarm - flashes slowly when below 3V - works perfectly with Cree XR-E R2 (...
