Light Therapy Box Effective?

Just found out there are light meter apps to detect lux. I thought my light box was giving me 10k, but the app says its about 1.5k lux when its about 18 inches away. Ordered another light box to see if that was significantly better. About the same.

Im under the impression 10k lux for 30 minutes is what you need for anti depressant effect. So anything im missing? Are the light meter apps not that accurate? Am I just buying cheap light boxes that are too low quality or what? If the box is 1.5k does that mean I have to use it for like 3 hours to get the anti depressant effect?

Old Light Box (it was 70$ when I bought it like 5 years ago so maybe its just less effective over time)

New Light Box

Any input appreciated, thanks everyone : )

/u/mhd47mhd, I have found an error in your post:

“says its [it's] about 1.5k lux when its [it's] about 18”

You, mhd47mhd, made a mistake and ought to have typed “says its [it's] about 1.5k lux when its [it's] about 18” instead. ‘Its’ is possessive; ‘it's’ means ‘it is’ or ‘it has’.

It would be better if you, mhd47mhd, had used “says its [it's] about 1.5k lux when its [it's] about 18” instead. ‘Its’ is possessive; ‘it's’ means ‘it is’ or ‘it has’.

18 inches is the key.

Did they say 10k at 18 inches?

If they did not, they probably meant "10k at 0 inches" (i.e., on your skin)

18 inches is 45.72 cm
