how to measure light fading

Wow, Rebecca! Thank You!

I was reading an article last year about permissible exposure times for lighting choices as compared to sunlight. I.E. 8 hours of fluorescent F0T12CW was equal to 6 minutes of sunlight at 30 degrees from zenith at 1000 lux. Being really slow at these things, I couldn't make the jump from the hours stated to the application.

The chart at Light Check cleared that up pretty quick! Now I understand better why limiting total lighting energy is as (or more) important than limiting UV.

Sounds like the Light Check is a neat little product!
 
Rebecca:

Customers often ask how to gauge the damaging effects of light in specific environments. Now we have a way for them to measure relative light damage.

Thanks!
