I am working on finishing my basement and planning on installing LED strip lights inside a lowered crown facing up.
Now where it gets complicated. I'd like the lights to have a dim setting to be controlled by a timer, on at sundown and off at midnight (easy too), but I would like the lights to come on at full brightness when the overhead lights are flipped on for the specific room. 5 zones in total, bathroom, kitchen, family room, hall and gym.
I don't want any software solutions with smart switches / dimmers, etc. (Aside from the timer switch) and no wireless anything.
I was originally thinking the easy way would be to have two strips, one at dim on the timer and the other controlled by the power for the light switch, but I don't like this idea because of the additional cost and I'd need 6 power supplies.
Better Idea (so I think)
I was thinking last night and thought about having two power supplies, one set to dim and one to full brightness. Then have 5 double throw relays, that are switched to low when it's not energized and then switch to full power when it gets a 120v signal from the overhead switch for the specific room. What I'm not sure about this idea is if the power supply will keep the LEDs in the different zones at constant brightness when the load increases/decreases. I'm thinking I just need a constant output voltage power supply, but I've never tried this myself.
(Not thrilled with having to run 14/2 for each overhead back to the utility room, but I can live with it. Easier than dropping the voltage and sending a 12v signal back)
Will this idea work or is there a better way to achieve my goal.
- No drywall in the basement yet (done with framing, plumbing and running electrical now), I can run anything anywhere.
- Total is about 200' of LEDs
- Planning on having all LED controls in one spot, utility room
- Power for LEDs will distributed with thermostat wire.
- White LEDs, no color.
- Each room will have additional lights, mainly 6" recessed
- Locale, US
- Mostly dealing with low voltage issue here, but I need to pass inspection NEC 2020 rules.
