Recessed spotlights for general lighting

@Molydeam & @dietmar, thank you very much for your feedback. In the bedroom, of course, there are bedside lamps, in the dining room a pendant lamp, and in the bathroom corresponding mirror lights planned. The spots in the dining room we will keep as passage lighting or when we need even illumination for cleaning. Again regarding the light intensity: The Philips spots have a luminous flux of 575 lm, which means I get about 230 lm/m² in most rooms. The Occhio have 1010 and 1290 lm, which means about 500 lm/m². On the internet, I find recommendations of 100 to 150 lm/m² for living and sleeping rooms. Wouldn't this be too bright? Or would you always dim these down to about 20%?

Hello,

the maximum luminous flux can never be enough when the luminaires are dimmable. Then the desired amount of light can be set at any time.

Best regards

Ok. Is the set light intensity "saved" or must it be adjusted again every time the light is turned on? Regards Andreas

Hello,

that depends on the dimmer, the lights themselves do not store anything.

Best regards

What luminous intensity would you specify per spotlight so that you can see well but it does not appear too glaring?
What beam angles would you recommend so that it does not appear patchy on the floor?

Stick to the recommendations for individual living areas and experience the values once in a good lighting studio.
You can determine the beam angles based on the distance to the illuminated object (usually the floor).
However, you cannot counteract "patchiness" with this parameter alone, as there are many lamps that already emit a "patchy" light pattern themselves. With cheap lamps, diffusion lenses can help somewhat to mask constructive defects.

the maximum luminous flux can never be too much if the lights are dimmable. Then the desired amount of light can be set at any time.

This is a frequently repeated misconception. More is clearly not more here. The more you dim, the more you enter a visible PWM range. The lamps flicker. It may be that this is only noticeable when swinging a pendulum – but the wellbeing in the room is disturbed. You can counter the PWM risk with a lot of money if you want to dim over a very wide range. If you don't need the very wide range anyway, it saves a lot of money and increases wellbeing if you simply do not provide for it and dim a narrower band.

It may only be noticeable when you swing a pendulum – but the well-being in the room is disturbed. You can counter the PWM risk with a lot of money if you want to dim a very wide range. If you don't need the very wide range anyway, it saves a lot of money and increases well-being if you don't provide for it at all and dim a narrower band.

Theoretically that may be so, practically I have never had a problem in this regard. I extensively use low dim values <20%.

Depending on the light source, there is no flickering at all anymore, since corresponding compensation electronics are integrated. I use MDT dimmers with the light sources mentioned above.
