We have many 4' fixtures with a hodgepodge of florescent and direct LED replacements
Most fixtures are producing significantly fewer lumens than their "new" capacity but still consuming as many watts.
There are many incandescent bulbs.
less critical since the "waste heat" warms the lodge.
also cheap to replace, since SCL subsidizes them
The fluorescents and direct LEDs in the cat house and zoo are particularly poor at delivering lumens
Alex, upon seeing me heading into the zoo with new bulbs, "Are you replacing the bulbs in there?" I replied, "Yes." Alex said with relief, "Thank god!"

Replace the fixtures in the commons area with new 4' LED fixtures #3
[x] Replace the bulbs in every other 4' fixture with LED bulbs #4
(35) fixtures were retrofitted, reducing each fixtures power consumption from ~100W (240W bulbs + 20W ballast) to 36W for a savings of 64W per fixture 35 = 2,240 watts.
[x] Replace every CFL and incandescent bulb with LED bulbs #5
