Satco Lighting S39929 – Frequently Asked Questions

1) Does the Satco S39929 3ft T8 LED tube need the existing fluorescent ballast, or does it bypass it?
It's a Type B ballast bypass tube, so the fixture's fluorescent ballast has to be removed or disconnected and line voltage wired directly to the sockets. If you want a lamp that runs off the existing ballast with no rewiring, you need a Type A tube instead, not this one.
2) Can the Satco S39929 be wired single ended or does it have to be double ended?
Either. The 12W 3ft T8 is listed for single or double ended wiring, so it works whether you bring line and neutral to one end or split hot to one end and neutral to the other. That matters when you're retrofitting a fixture with shunted sockets on one end, since single ended wiring requires non-shunted sockets at the powered end.
3) How bright is the Satco S39929 compared to the 25W fluorescent tube it replaces?
1450 lumens on 12 watts. A 3-foot F25T8 fluorescent draws 25 watts, so you're cutting connected load roughly in half at comparable output for a corridor, shop, or stairwell fixture.
4) What does 5000K look like in an office or warehouse?
5000K is a crisp, neutral-to-cool white with a slightly blue cast, common in warehouses, garages, back-of-house, and task areas where you want high perceived brightness. If the rest of your building is on 3500K or 4000K tubes, this one will read noticeably cooler next to them, so standardize by color temperature across a space.
5) How long does this Satco T8 LED last before relamping?
Rated at 50,000 average hours. On a 12-hour-a-day schedule that's roughly 11 years, which is why property managers and MRO buyers use these to get relamping out of the annual cycle on high-access-cost fixtures.
