Satco Lighting S39927 – Frequently Asked Questions

1) Do I need to remove the fluorescent ballast to install the Satco S39927 3ft T8 LED tube?
Yes. The S39927 is a Type B ballast bypass lamp, so it runs on line voltage direct to the sockets. The existing fluorescent ballast has to be removed or disconnected and the sockets rewired before the lamp goes in. If you want a tube that drops into an existing fixture with the ballast left in place, a Type B lamp is the wrong choice.
2) Can the Satco S39927 T8 LED be wired single ended or does it have to be double ended?
Either. The S39927 is built for single or double ended wiring, so you can land line and neutral on one end or split them across both ends depending on how the fixture sockets are configured. That flexibility is useful when you are retrofitting a mix of older strip fixtures and do not want to change out tombstones on every one.
3) Will the Satco S39927 fit a standard 3 foot fluorescent fixture?
It uses a medium bi-pin base in a 3ft T8 form, which is the same lamp geometry and socket as a standard F25T8 3-foot fluorescent tube. Mechanically it drops into the same sockets. The electrical side is what changes, since the ballast has to come out for this ballast bypass lamp.
4) How bright is the Satco 12W 3ft T8 LED compared to the fluorescent tube it replaces?
1400 lumens off 12 watts. A 3-foot fluorescent T8 is typically a 25 watt lamp, so you are cutting connected load roughly in half at comparable output. For corridor, stockroom, and back-of-house strip fixtures that output reads as a like-for-like swap.
5) Is 3500K the right color temperature to match the other tubes in my building?
The S39927 is 3500K, a neutral white that sits between warm 3000K and cool 4000K. If your existing lamps are 4000K they will read noticeably cooler side by side, so relamp a whole room or run rather than mixing. 3500K is the common choice for offices, schools, and healthcare corridors where 4000K feels too blue.
6) How long will the Satco S39927 LED tube last before it needs replacing?
Rated at 50,000 average hours. On a 12-hour-a-day schedule that is over 11 years of service, which is the reason MRO and facilities buyers move to ballast bypass LED: the rewire is a one-time labor cost and the relamp cycle largely goes away.
7) What is the part number to order the Satco 12W 3ft T8 LED, and does it come in more than one version?
Order it as Satco S39927. It is a single configuration, 12W, 3ft, 3500K, medium bi-pin, finished in gloss white. If you need a different color temperature you are looking at a different Satco part number, not an option on this one.
