SATCO Lighting S49976 14W, 4 Foot LED T8, Medium Bi Pin Base, 3500K, 50000 Avg Rated Hours, 2200 Lumens, Type A, Ballast dependent

Yes. The S49976 is a Type A, ballast dependent lamp, so it runs off the existing fluorescent ballast in the fixture. You pull the old F32T8 lamp, put this one in the same medium bi-pin sockets, and that's the job. No rewiring, no ballast bypass. The trade-off is that the lamp depends on that ballast staying healthy: if the ballast fails, the lamp goes dark until it's replaced. If you want the ballast out of the picture entirely, you need a Type B (ballast bypass) tube instead, which does require rewiring the sockets to line voltage.

At 14 watts the S49976 puts out 2200 lumens at 3500K with an 82 CRI. A standard 4 foot F32T8 fluorescent is typically in the 2600 to 2900 lumen range when new, so this lamp is a step down in raw output, though fluorescent lumens depreciate over life while the LED holds up better. For corridors, storage, parking structures and general office ambient it reads as an even swap. In spaces where you were already short on light with the fluorescents, go to a higher output LED T8 rather than this one.

The lamp measures 48 inches and is a T8 shape on a medium bi-pin base, which is the same lamp geometry as a standard 4 foot F32T8 fluorescent. It drops into any 4 foot troffer, strip, or wrap fixture with medium bi-pin tombstones. Weight is 0.41 lb per lamp.

3500K is a neutral white, between the warm 3000K used in hospitality and the cooler 4000K common in offices and schools. The S49976 is fixed at 3500K, not field selectable, so you cannot dial it to match an adjoining area. If the other tubes in the building are 4000K or 5000K, the difference will be visible in the same sightline, so order the whole run or the whole floor at one temperature. CRI is 82, which is the normal range for commercial troffer lighting.

The S49976 carries a damp location rating and is listed for indoor use. That covers enclosed parking structures, covered exterior walkways, and mechanical rooms where condensation is possible, as long as the lamp is not exposed to direct water or weather. For wet locations or anywhere the fixture takes direct rain or wash-down, this is not the correct lamp. Burning position is universal, so it works in vertical, horizontal, or angled fixtures.

Yes, the S49976 is rated 120V through 277V at 50/60Hz, so it covers both 120V tenant spaces and 277V commercial and industrial branch circuits off a 480/277 system. Current draw runs 0.117A down to 0.051A across that voltage range. Keep in mind it is a ballast dependent lamp, so the existing ballast also has to be rated for the circuit voltage it is already on.

The S49976 is listed as dimmable. Because it is a Type A lamp operating off the fluorescent ballast, dimming performance is determined by the ballast in the fixture, not by the lamp alone: a non-dimming instant start ballast will not dim it no matter what control is on the wall. If dimming is part of the scope, verify the installed ballast is a dimming ballast matched to its own control protocol.

It is DLC approved and listed as Title 24 compliant, which are the two things procurement usually needs: DLC listing is what most utility prescriptive rebate programs require for LED linear replacement lamps, and Title 24 compliance matters for California projects. It is also FCC compliant, which is worth noting in facilities with sensitive electronics or RF equipment. Rebate amounts and program rules vary by utility, so confirm the current measure with the program administrator.

Rated life is 50,000 average hours. On a 12 hour per day, 7 day schedule that is roughly 11 years of service, which is why MRO and property teams use these to get off a relamp cycle. One caveat for a Type A lamp: it depends on the fixture's fluorescent ballast, and the ballast will usually not last 50,000 hours. Plan on ballast replacement as the likely first failure, or move to a ballast bypass lamp if you want the ballast out of the maintenance picture.

It is a glass lamp, listed with glass base, lens, and body material. In food prep, food service, or any area with breakage exposure, glass tubes are generally required to be in an enclosed fixture or sleeved, so check the facility requirement before specifying. If shatter resistance is a hard requirement, you want a coated or plastic-bodied LED T8 instead of this one.
