Hi
I'm building a new house and I would like to install LED downlights.
I have a couple of questions.
1) I would prefer constant current led downlights so I can install my led drivers in a common place (next to my circuit breakers) and have slightly longer cables. Now, I was thinking of buying armatures with simple GU fittings and put a GU fitted LED bulb in that. But it looks so expensive and I have not found many products online. Most LED armatures have to be completely replaced when the LED breaks. By the time the led breaks you probably can't buy the same model. What's your opinion on this?
I have yet to choose armatures and light bulbs so I can still change. Anyone knows a good online shop?
2) Cabling of the LEDs.
I want single coulour, white LEDs in my house. I was thinking of running a separate 1.5mm2 cable to EACH downlight. The advantage is that I can control each downlight individually if I would find the need for it. (very unlikely though) The disadvantage is that my cable length becomes very very long if I put a couple of downlights in series. Each downlight is maximum 15m away from the circuit breaker area. Alternatively I just install a 2,5mm2 cable for every 3 or 4 downlights.
I have a total of 40 downlights (divided into 11 areas)
What should I do with my cables? Is constant current a good choice?
3) LED Driver
I'm looking for some good and not too expensive LED drivers, preferable with 0-10V and/or DMX capabilities for integration in my home automation (KNX/Loxone). I was looking at the eldoLED PWR090D2 which has 4 channels (RGBW), can I use those four channels for WHITE ? For my total of 11 areas I would need 3 to 4 of these if they're suitable for my set up. Which power supply should I use? I suppose that depends on my cable lengths (output is Vsupp - 1V) but probably 24V/4.2A is sufficient for each 90W driver, right? Any alternatives to the eldoLED ?
Thanks!
