Satco Lighting S39717 – Frequently Asked Questions

1) Does the Satco S39717 T5 LED tube need the existing fluorescent ballast, or does it have to be removed?
The S39717 is a Type B ballast bypass lamp, so the fixture's fluorescent ballast must be removed and line voltage wired directly to the sockets. It will not run on an existing ballast. If you want a lamp that drops into the fixture with the ballast left in place, you need a Type A plug-and-play tube instead.
2) Can the S39717 be wired single-ended or does it have to be double-ended?
Either. The 25W T5 LED accepts single or double ended wiring, so it works whether the fixture brings line and neutral to one socket or splits them between the two ends. That matters on retrofits where you want to reuse the existing non-shunted sockets rather than replace them.
3) Will this Satco T5 LED work on 277 volt lighting circuits in a commercial building?
Yes. The S39717 is rated 120-277 volt, so the same lamp covers 120V residential and small commercial circuits and 277V commercial or industrial branch circuits. One part number standardizes across mixed-voltage facilities.
4) What base does the S39717 use, and will it fit my existing T5 fixture sockets?
It uses a miniature bi-pin (G5) base, the standard T5 fluorescent socket, so it seats in existing T5 lampholders. The electrical side is the catch, not the mechanical one: because it is a ballast bypass lamp, the sockets have to be fed line voltage after the ballast is removed.
5) Is 3500K the right color temperature to match the other lamps in my building?
The S39717 is 3500K, a neutral white that sits between warm 3000K and cool 4000K. It is a common office, corridor, and healthcare standard. If the rest of your fixtures are 4000K or 5000K you will see the difference side by side, so match the lamp to what is already installed on adjacent fixtures.
6) How much light does the 25W Satco T5 LED put out compared to the fluorescent it replaces?
3200 lumens at 25 watts. That output and wattage puts it in the range of a high output T5 fluorescent lamp, so it is specified for HO fixtures rather than standard 14W or 28W T5 lamps. Check what is currently in the fixture before ordering so the light level does not change.
7) How long does the Satco S39717 last before relamping?
Rated at 50,000 average hours. On a 12 hour per day schedule that is roughly 11 years of service, which is why MRO and property maintenance buyers use these to cut relamping trips in high fixture count spaces like garages, corridors, and warehouses.
8) Is the Satco 25W T5 LED clear or diffused?
Frosted. The frost lens spreads the light and softens the individual diode images, which matters in open fixtures and strips where the lamp is in direct view.
