Sorry to add yet another lighting thread to the mix.
So when you consider ceiling height and lumens is a higher lumen fixture more effective than a lower lumen fixture as ceiling height increases?
Stay with me for this example: let's say you're comparing one 8000 lumen fixture vs two 4000 lumen fixtures. The lumen output is equal but does the 8000 lumen fixture get more light to the bench?
I have two lighting plans in front of me and one specifies less fixtures (9 total) with a greater lumen output per fixture and the fixtures are hard wired. The other uses more fixtures (20 total) that have a lower lumen output per fixture and these are the less expensive plug in type fixtures.
Overall lumen output is 58000 (for 9) vs 82000 (for 20). And the 20 fixtures are roughly $200 less but require 12 outlets in the ceiling.
Still waiting to hear back from another light supplier who has 92-95 CRI LEDs which for fixture type and lumen output compare closest with the 9 in the above scenario.
Ceilings are mostly 12', building is 36'x30'.
Anyone have a thought on this? Help!!
