Customers would absolutely love a spread sheet with suggested fans for removing heat from light/room and also number of lights that can be cooled with each individual fan. Also if using a filter and cooling a light. Maybe a simple CFM calculator that takes into consideration, ducting angles, Duct length, can filter being used, Light wattage, room size. I don't know maybe there are too many variables and each situation is different, especially when considering fresh air temps, but regardless it's nice to have the 1-3 minute air exchange in a room. I guess my one question would be Is there any guide like this available besides the simple guide that is on the side of every can filter?

P.S. Can Makes the best filters and fans on the market.
