That last one for the Tek lights is usable by multiplying the number of bulbs by the PAR per bulb. But, Catalina uses different shaped reflectors in various light fixtures, so the number is only good for those with similar reflectors (the one bulb Catalina lights appear to use the most different reflector shape.)
This research is awesome and I think it s much more details than the previous charts. Thanks for your clarification.. and please keep us posted with your new studies.....
