Inside of one of the troffers

These are Cooper troffers from the late 90s that came out of my old middle school (from 1970). These have Advance dimmable programmed start ballasts. We didn't hook up the dimming circuits. Not something either of us were interested in (IDK how to wire them for that anyway; you can't use a regular resistive dimmer). The lamps used are GE SPP41s. We bought a case of 30 from Lowe's. My grandpa's go-to place (Home Depot) was thankfully out of the 30-pack of cool white Altos so we went to Lowe's since buying a bunch of 10-packs or buying a 30-pack of 3500K ($76) or 6500K ($116) was way too expensive. The 30-pack of GE SPP41s was $52 and GE tubes are MUCH higher quality than Altos.

The tubes started up instantly at full brightness. None of that dim/flickery bullsh!t that the other brands have (Philips are fine once you break 'em in but Sylvanias are always like that) and no duds yet. They're rated for 30,000 hours, but being on programmed start they could potentially last even longer. I'm really happy with these tubes.

Yeah, I hear ya. Sylvania has really left me disappointed this last ten years or so. It's pointless to have good electrodes and what not if there isn't enough mercury for lamps to even last half the rated life. Not just dim start-ups, but most F96T12/HO's at my work are replaced because they run out of mercury. I almost never see them make it to EOL anymore.

Yeah GE seems to still be pretty generous with the Hg dosage. Even though they're Ecolux lamps, they act full mercury. Even on the fist power-up these were not dim in the middle or anything. I was surprised since I was expected that on the initial start-up.

To resist is to piss in the wind, anyone who does will end up smelling.
