The highest lux I measured outdoors was in full sun around June, was 130,000 lux. So I would go for the 200k model.

Got one of these a while back....not saying it is measures precise but as indicator its okay...
insane to see that outside in full sunlight when you go to the shade ....lightlevel is lower than a 20w t8 tube at seedling distance..and so on. very good to compare different lightsources.
as okay as I would recommend it.
it's 10$ and for me it was worth every penny.
200000 lux.
