I was curious what everyones take was on their use of lamp and fixture phtometrics. Do you use them when working the spacing of a pathway or wall lighting application during the design phase, or do you just sort of wing it with an educated decision based of of experience? And as for Lumens I know that lighting projects such as Dark Sky and commercial hotels and hospitals will require maximum and minimum Lumen outputs. But how many of you have ever ran into this, and if you did how did you obtain your Lumen information? Joey D.
