Suggestions for setting/adjusting room light temp?

->> I'm calibrating my monitors, and want to set my room lighting to 6500K. I have Philips Hue lighting, and it's certainly possible. ...but there's no scene or recipe for particular Kelvin adjustments. I'm sure someone on this board has conquered this already.

Here are your options:

Go to Costco and get yourself a box of Felt 100w daylight 5000k LED bulbs and use them in your ceiling and lamp fixtures. I have them and they're great. They are not 6500k but close.

Use a color temp meter, take a reading of your Philips lighting, adjust its hue, take a reading, adjust, and repeat until you reach 6500k.

If you don't have meter but have a Nikon D850 -- or know someone who has -- use its built-in color meter that gives Kelvin readings. To do, set the camera on auto white balance and auto-exposure; shoot a white piece of paper or neutral gray card; and look at the frame's data info on the camera's back screen. Next to the Auto-WB setting is the Kelvin number. FYI, shooting a white piece of paper on auto-exposure turns it into an 18% gray card. Read the number, adjust the Philips lighting, reshoot, look at the number, and repeat until you reach 6500k.

If you don't have a Nikon D850 or access to one, shoot a white piece of paper or gray card just like above but shoot it RAW. Load the file in Photoshop Camera Raw and look in the upper right corner of the CR screen for the Kelvin number. Adjust the Philips lighting, shoot another RAW frame, load into Camera Raw, read the Kelvin number, and repeat until you reach 6500k.

The fourth option is the easiest and cheapest, and is used by pro print labs, conscientious newspapers, magazines and movie/tv productions wanting to obtain optimal color results. Simply turn off your room's lighting and work in a darkened room where there is no light pollution to alter your monitor's color balance. You can have on a single desk lamp off to the side so you can see your work area; just make sure it doesn't shine directly on the screen. My desk lamp has a Costco daylight LED bulb. My color balancing work is dead on with this method.

->> Whoops. My bad.

I'd get a Minolta color temperature meter.

Cheaper one used...

->> Thanks for the responses. I should’ve clarified, I don’t need new LED lighting. My Philips Hue lights can be set to any one of 16.1 million colors, but the only option when picking a particular color is the color wheel. Most of the preset scenes are mood based like “tropical sunset”, “spring blossom”, etc.

I was curious if anyone had found/created a preset that is pegged to the Kelvin scale ....so you could just set the rooms lights from the phone app when you want to edit.

FWIW, As it turns out, it seems the “concentrate” setting is probably pretty close to ~6500, as my spyder5 ambient light test didn’t recommend any room lighting modifications when I performed the calibration.
