Modifying two color LED driver

[viriol]

I've got a 300 mA LED driver for a ceiling lamp. It works like this:

1. Turn on the light switch = all warm LEDs light up
2. Turn off/on again = all cold LEDs light up
3. Turn off/on again = both warm/cold LEDs light up

I would like only the warm LEDs to always light up. What do I need to do to make that happen?

When the warm LEDs are lit:
~110V DC power between A (yellow) and V+ and also between A and B

When the cold LEDs are lit:
~110V DC power between B (white) and V+ and also between A and B

When all LEDs are lit:
~100V DC power between A (yellow) and V+ and between B (white) and V+

Thanks in advance!

That sounds like a job for Big Clive.

But seriously, I would cut the white wire only. This way your lamp will switch state on every switch click if I understand your explanation.

Or better yet, maybe not messing with mains voltage equipment is the best advice.

My logical guess for cutting white wire would be:

1. Switch on = warm light
2. Switch off/on = dead
3. Switch off/on = warm light

...back to 1...

Ah, I presumed there was a:

4. Switch off/on = off

So "Switch on" and "Switch off/on" are different switches?

Never mind, I think I get it.

They look like relays!

No cutting.

Disconnect the wire for the colour you do not want. Connect the terminal for the other wire to the terminal from which you disconnected it.
