If you do go the phone-metering option, I'd try to test the metering provided by your cell phone camera by taking digital photos (or a test roll) using the suggested exposure to be sure that it's accurate. I believe on iPhones it's pretty consistently good, but I found that on my old HTC phone, the metering apps weren't very accurate. You can also get an actual light meter attachment for your phone to improve accuracy.
Well… this little photography project is more complicated than I anticipated. If I lock the exposure on my phone to make the comparison, one photo is either very yellow or very blue, due to the crisp white of the Aurora vs. the warm white of the incandescent bulbs. Also, the shadows are weird from the overhead light vs. the wall-mounted Aurora.
Here’s what I ended up with: yellow one is the incandescent overhead light in the ceiling.
It probably makes more sense to use a light meter across the room from the light source rather than taking photos, but… I don’t have a good light meter. The gizmo on my phone tells me the overhead light is less than half the lux of the Aurora, which can’t be right (maybe it’s the effect of RGB white LEDs vs limited-gamut incandescent warm white?).
Anyway, if anyone has any advice on how to go about it, I’m open to suggestions.
