eli5: How does my UV flashlight have a higher uv index rating than the Sun

915 viewsOtherPhysics

When I measured the sun, it gave a UV index of 6. When I measured the uv flashlight, it gave a uv index of 196. Is the sun not more powerful in UV than the flashlight?

Like others have explained so much closer, no atmosphere blocking the sun. And I would think and hope its also the on the weak UV spectrum.. UVA I believe, if it was 196 on UVB that would give you sunburns in seconds if exposed to it, and I’m sure not legal to own, or at least not to sell to the general population
