Seen at the subway recently. At least they kept it T12 lol.
The same station also has a bunch of 34w lamps that get really dim every winter. The full wattage 30w and 20w lamps fair a lot better. I'm surprised they didn't use HO lamps in these fixtures.

We should all take a vote, who here likes 4 4ft lamps per a fixture? and that is right 0 do
As for the LEDs, they are even worst the T8 IMO, they have bad light distribution, and they put out a useless amount of light compared to a T8. That and they don't really save that much to begin with. I'd much rather switch to a lower BF and use 25w T8s before I'd use one of those things.
As for HO and VHO they are sadly less efficient than T8. A T8 with a 1.2 BF ballast can probably rival a T12HO lamp. While HO and VHO are pretty neat and I also keep one in my garage as a showpiece. They are becoming a thing of the past in the commercial world.
I don't mind LPS outdoors but indoors is another story. Even though it's efficient, no one likes working under 0 CRI yellow light.
The tandem fixtures do have their uses TBH, 4ft lamps are easier to handle in cramped spaces so using them makes relamping easier. And plus I'd much rather have a well made tandem light with a decent ballast over a tin can light sold at the box store.
That said you got a spec sheet to them?
