12V LED and drivers

good luck. take pictures :slight_smile:

I looked at it last night, but was confused about switched. In the comments someone suggested switches rated at 1.5A but driver is well over 2A.
I didn’t feel comfortable with higher current while my and other listed switches are rated for 1-1.5A

Input current is ~1A at 12V, so if you’d switch input, not output (switching output on such driver, actually, is not recommended at all!) you’d be fine.

Thanks for all the help :slight_smile:
Here is current build. The questions are for the next build that should double light output.

I have the same led as mentioned in post 0.
Any datasheets available? Who is manufacturer?
I tried it and it looks very nice.

I have this driver which is 1A capable and dimmable like the other one.

A lot of those PT4115 10W drivers have 0.2 and 0.3 ohm current sense resistors in parallel. This gives around 750 mA out. You can parallel them with another 1 ohm resistor to get closer to 1 amp output. When I tried pushing one to the 1.2 amp rating of the chip, it went into thermal shutdown mode. Also, it would probably be a good idea to not let that filter cap rest on the driver chip… it gets warm.

So what is this LED, datasheet?
