    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month Pros:The driver is made on three linear current stabilizers AM?7135. It is difficult to find a driver for LED 3W or more (for example,Cree Q5) I put in my flashlight Sipik68 (for a Li-battery 14500). During the whole battery charge gives direct current. Accordingly...

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:This will be a review for the 700mA board since that is what dx sent out. It is essentially the same product but with one chip difference. Quiet, constant and easy to solder to. Will run an array of emitters. Does not get too hot. Cons:I got the ones with only...

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month Pros:Very cheap, very simple It is basic configuration for those AMC 7135 integrated current regulators - basically there is nothing else on the board - just two!

Cons:can't think of any, maybe leads on both ends of the driver? so i don't have to solder them onto the brass(?) plates and risk frying the driver. OtherThoughts:bought some cheap Ebay "5 watt" flashl... Read more

    Involvement:Novice  (still getting used to it) - Ownership:1 week to 1 month Pros:Has three AMC7135's. Simple easy way to regulate current to an LED. I like the fact the voltage starts at 2.7V. Nice when you are trying to drive a Red LED with out a voltage regulator too. Doesn't get too warm. Saves the LED. Allows batteries to last longer.... Read more

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week Pros:very small and works. It can be shaped with a grinder to fit into almost anything (may need a little resoldering). It doesnt heat up with extended use at all which means that it wont need to be mounted to a heatsink (as if anyone would anyway). Cons:The outer go... Read more
