Want to step up my game and check the efficiency of my lights. Let me know if you have a par meter you would like to rent.

i dont own one, but i've used the iphone app "photone" before.. requires a $5 purchase for the full spectrum but its been compared to some of the other popular par meters with some really good results.. check R2R
