Can anyone recommend a good light meter that would help me determine which areas of my house are 'bright', 'medium', and 'low' light? I'm curious how much light is actually coming through in certain spots. Eyeballing it is a little subjective and I'm thinking a couple of my plants are struggling as a result of being misplaced into incorrect lighting situations in my home.

And, if such a thing exists, is there a light meter that 'records' amount of light over a 24-hour period so that you can see the 'average' and/or per-hour light your plant gets? (This would be useful in areas where the sun might make the room brighter during one part of the day, but dark another part of the day.)

There are light meter smartphone apps that could give you a comparison, I assume they use the cameras sensors. I do have a physical light meter as well that gives foot candle readings, it's made by Hydrofarm and I got it from Lee Valley. I don't know how "good" it is since it's the only one I've got so can't compare. It wasn't expensive.

Do a search on Amazon for "greenhouse light meter". There appear to be a BUNCH of them!

I saw that Blinking It makes it hard to know what to choose. The big box stores have some, too.

I'm hoping to find out who has brands/models that they use, they like, and that work. (I nearly bought a light sensor last year from a place and it showed the same readings when I put it in a dark area as when it was in full, bright lights...I promptly put it back on the shelf.)
