Damn, don't use your DX 200k meter, or any meter, at 1m.

My Fandyfire, Solarforce MPP-1 measured 23-25k at 1m measuring distance. LOL!

Sheesh, now I do not know what's the accuracy even at 200 and 2,000 lux modes. I do know that my unit under reads quite a bit, so i automatically add 7-10%. But not like the 200000 lux mode, that is like 100% off.
