    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. - Very small pa...

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week Pros:True linear current regulation (thanks to AMC7135 chip) Maximum LED performance Well built Easy to install Easy to disable annoying flash modes without soldering Cons:No transparent information about LED +/- soldering pads. OtherThoughts:It will give the maximum... Read more

    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 stac... Read more

    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 need a flashli... Read more

    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 OtherThoughts:Great little board. Not for a total beginner but if d... Read more

    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 f... Read more

    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 regulate t...

    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 siz... Read more

    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 useful) - h...
