FCO versus Sag Refractor

FCO versus Sag Refractor

Click to view full size image

There are 3 sag refractor heads, 2 of which are OVZs, and there are 3 FCO GE M-250A2s.

Why did "lighting experts" decide that 150 watt lamps should be installed in all these heads? Because their mindset was anchored in cement.

Nice comparison. I wonder why the differences are so drastic between lights. Do the bulbs really dim out that much with age? Or dirty refractors perhaps?

BTW on a side note, sag lenses are different from drop lenses. Sag lenses are clear glass and look like FCO glasses, but sag an inch or two down rather than being flat. Drop lenses are deeper and have prisms to control the light. The refractors in this collage are drop lenses.
