I have a Beamswork LED aquarium light like this. It has a 3 way switch:
- All LEDs off
- Blue LEDs on only
- White AND blue LEDs on
It has a single mains power plug.
What I want to do is make it have two mains wall plugs. I want one to power the blue LEDs all the time, always on.
I want the 2nd plug to power the white LEDs only, and this will be plugged into a plug timer like this, so the white LEDs will independently go on and off by time, while the blues stay on (because that will be plugged in separately - I hope).
I opened the cover and found this:
The 2 black wires connected to the brown PCB is where the mains adapter plugs into. Then there are 3 blue-covered connectors which are connected to the 3 way switch. I don't know which ones control which colour as I didn't test it plugged in, but I think the white one is white LED, the middle one is power, the one I'm holding had a blue wire so probably blue LED. Is there a way to connect a 2nd mains plug to that blue LED connector (if it is that) so it powers separately? Drilling through the plastic to get a wire in is fine, but I don't know how what electric connectors or connections I need.
I don't know much about electrics, first-time project! Thanks.
EDIT: This is is the spec of the adapter:
And here I have done a few tests:
- Wire 1 controls the "blue ONLY" LEDs from the switch
- Wire 2 comes from the mains adapter
- Wire 3 controls the "white AND blue" LEDs from the switch
- Wire 4 goes to a metal thing on the LED board saying "Ground"
If I disconnect wire 1 and put the switch into the "blue only" position, the blue LEDs don't come on. But if I put the switch into the "all on" position, the white AND blue LEDs do come on.
If I disconnect wire 3 and put the switch into the "blue only" position, the blue LEDs do come on. But if I put the switch into the "all on" position, the white AND blue LEDs don't come on.
I'm thinking of getting a second power adapter and a male connector to fit directly to wire 1 (so disconnecting wire 1 from the original switch above), so I can keep the blue LEDs always on. But I'm worried, since wire 3 turns on both the blue and white LEDs (even if wire 1 is disconnected), will this make the blue LEDs get double power and cause a problem?
My goal in the end is to have the blue LEDs always on (because they will be powered separately from a new mains adapter) 24 hours a day. And the white LEDS (which also turn on the blue LEDs too) to be plugged into a plug timer and turn off at certain times of the day. Any suggestions?
