Hi everyone,

My living room is north-facing, and outside of summer it’s quite challenging — I’m constantly missing natural daylight. The room is about 5.5 × 4 m with a 3.2 m ceiling.

Does anyone have experience with human-centric lighting (HCL)? For example, what lights or LED strips work well?

From what I understand, it should be properly designed — starting with the required lux levels, then choosing LED strips that best mimic daylight, and also considering cooling and power supply for the setup.

Any advice or real-world experience would be really appreciated.

Thank you!

I watched a video years ago where a guy repurposed old LED TV screens as skylights. The effect was pretty neat.

Edit:

 

the old dayz are gone

there are led strips etc... which can help here. the question is - know how to design all above mentioned

 

5500K to 6000K is considered daylight. Below is a link to Walmart. They sell "Happy Lights" designed to lift ones mood by simulating natural daylight. This one is adjustable.

The honest producers of LED lighting usually are able to provide information about the spectrol elements provided by their products. That is often referred to as the color temperature. That information is usually available on product data sheets. (Often not available from some sellers.)

 

Many led strips on line that allow colour temperature to be set by user .
Even the led lights in our bathroom, had switches in them to select colour temperature.
When I was in Norway / Finland in the winter , 24/7 dark , we had rooms with very bright lights we all went to for lunch. It seemed to help

 

i think its not about the temperature of the light, its also about its characteristics ie if it can simulate they daylight its spectral analysys

thanks

 

fyi.
light "colour" is its characteristic
when it comes to "white light" , there are a range whites , identified by their " temprature" .
this goes back to tungston filiments , where at different currents, they had different tempratures , produced different colour .

@drjohsmith i dont know, but that spectral analysys close to daylight is also important parameter, isnt it?

why ?

 

The less confusing term that is used is "color temperature." That made more sense in the past when the only way toproduce light was to heat something until it glowed. Then luminescence was discovered, which seldom involves much heat. NOW LEDs schanged everything. BUT "color temperature" is still a useful concept.
