Refelction factors

What should be the ideal reflection factors of floor,ceiling and walls in sports?

As the difference of just 10 in the reflection factors gives very different results?

Glare rating (GR) and UGR difference

What is the difference in GR and UGR?

As both options are available in calculation,I get confused!

Also,when should I select GR and when should I select UGR ?

What are their expected values (minimum values) for sports lighting ?

Thanks,

Gaurav

Re: Vertical illuminance uniformity

Yes I can do that.

But,how can I do it for vertical illuminance?

As the luminaire is same and has no relation with horizontal and vertical illuminance.

I have sent my file on ur email ID..Can you check it?

Thanks,
