P7 drivers

LEDBE
The DX is a good driver, but pretty inconsistent... Some 2.2A some 2.8A

Got 5 off them, all 5 only 2,0A :sigh:

Funny thing is, I don't really notice great lumen increase after about 2.3 amps or so... So, does it really matter if you get 2.8A? Anyone think the same?

I'm looking for driver replacement for a P7.

From your experience, is this one delivering promised 2.8A?

or would you recommend others instead?

I order some and after the confirmation that they are in stock the last 2 week message is "Processing - Awaiting Stock"

I don't know if you read this post after but it was for a MC-E.

I don't know if you can use 2 in pararell but I recomend those drivers

They use the ZETEX 1360 that is rated to 25W, at 10W they produce litle heat and this driver is cheap and small.

I have that driver listed as "buyer beware" because users have reported poorly regulated output as low as 1.95 A instead of the 2.8 A claimed. I would stay away from it myself, as I like to know what I'm getting and I like constant current output from my drivers. But to each their own.
 
Hi guys,

I ordered this driver: kaidomain P7 super output 3 mode driver

I received it this week, but it came with something that seems to be some kind of soft heatsink:

it seems to be made to sit around the component that sticks out a bit (the one with the copper wire).
Anyone seen this before? should I use it?

I guess it will be better to use some thermal glue to attach it to heatsink. Not sure what to do with this...

also, I couldn't find any indication on where to connect the batteries.
there is a metal plate on a little pole, which I suppose needs to touch the + of the batteries. There are also some pieces of copper on the side. Should I connect one of these to the - of the batteries?

regards,
Johan

Use your link in the last photo shows how to connect it, the red wire is the positive of the led, the black wire is the led negative, the center terminal is the batery posite and the orther the negative of the batery.

do you mean that metal piece that is visible on the side of the driver or the little hole in the board with metal around it (next to C1)?

Usually the negative of a torch is conducted by the body so I'm sure that is the 2 metal pieces on the side of the driver, it's possible the metal next to C1 it's also connected to them check it with a multimeter but it's also possible that it's the opposite side of the LED - terminal.
 
Battery - goes to the outer diameter contacts on the board. there should be 2. Battery+ goes to the central metal post.
LED +- go to the pre soldered wires.
I never use the rubber heat sink thingie but instead drill a hole in a heat sink big enough for the coil on the board then thermal glue the boat to the heat sink so the FET and diode make good contact.

I have never had one of these drivers fail when used in this way.
