I got an E-mail from MACO today, that contained a link to Sanjay Joshi's
collective lighting research:

I have learned a lot from these articles, and I recommend that any reefer
check out details of their own lighting ,for possible tweaks and adjustments or to compare types and sizes before you purchase that new mega watt set-up.
Lots of data, enjoy!..(.And a must if you ever want to argue lighting with Steve
