Hi all,
I have a cheap rainbow christmas light set off Amazon which has this little power supply that has a button to change modes. I had a white set with the same power supply that I returned but I can't find any other rainbow themed ones that don't use this setup.
Anyway, the problem is every time you unplug them and then plug them in it reverts back to "Combination" mode which cycles through all these annoying tacky effects instead of going back to what you had selected or at least defaulting to "Steady on" which is what I want. So I'm thinking I can just find any approximately 30V DC power supply and use that instead, but I'm wondering if that actually works. How does the power supply communicate to the LEDs which effect to use? I tried to use my multi-meter but the battery is dead and I don't have any other 9V batteries so I can't tell what it's doing.
Thanks for any input.
Edit: I went on Amazon and there are "steady on" versions of these power adapters but they have this note: "This item only with steady on mode, it is only replace for 30V 0.4A led transformer with steady on, it can't replace for 30V 0.4A led transformer with 8 lighting mode with multiple settings. If your original transformer is multiple settings, please go to our store and choose a right multiple settings one to replace it."
And there are reviews stating that people tried to replace their 8-mode one with the steady-only one and it caused only every other LED to light up. So confused!
