SATCO Lighting S49935 11W, 4 Foot LED T8, Medium Bi Pin Base, 3500K, 50000 Avg Rated Hours, 1800 Lumens, Type A, Ballast dependent

Yes. The S49935 is a Type A lamp, meaning it runs off the existing fluorescent ballast. It is ballast dependent, so it drops into the existing medium bi-pin sockets with no rewiring and no ballast bypass. The trade-off is that the lamp only works as long as that ballast works: if the ballast fails, the lamp goes dark until the ballast is replaced or the fixture is converted to a ballast-bypass (Type B) lamp.

It will. The lamp is a T8 shape, 48 inches long, with a medium bi-pin base, which is the same lamp geometry and socket as a standard F32T8 fluorescent tube in a 4 foot troffer or strip fixture.

1800 lumens at 11 watts is on the lower-output end for a 4 foot tube. A typical 32W F32T8 fluorescent runs closer to 2800-3000 lumens new, so swapping one-for-one in an office will read dimmer, especially in a two-lamp troffer over a desk. It works well in corridors, stockrooms, stairwells, back-of-house, and anywhere the existing lamps were over-lighting the space. For task areas, step up to a higher-lumen 4 foot T8.

Voltage is handled by the fixture's fluorescent ballast, and the lamp is rated for 120V through 277V operation at 50/60Hz. That covers both residential/light commercial 120V circuits and 277V commercial lighting branch circuits, so the same lamp can be standardized across a mixed-voltage building. Current draw is 0.092-0.040A.

The lamp itself is listed as dimmable, but because it is a Type A lamp running on the fixture's ballast, dimming performance depends entirely on that ballast being a dimming fluorescent ballast and on the control wired to it. On a standard non-dimming instant-start or programmed-start ballast, the lamp will run full output only.

No for anything exposed to weather. The S49935 is rated for indoor use with a damp location rating, so it is fine in enclosed fixtures in bathrooms, kitchens, covered interior areas, and humid utility spaces, but it is not a wet-location lamp for open exterior or washdown applications. Burning position is universal, so it can be mounted horizontally, vertically, or in a tilted strip without affecting rated life.

It is a glass lamp, with glass lens and base materials, weighing 0.4 lb. For a gymnasium, school corridor, or any area with impact or ball-strike risk, a glass tube is the wrong call unless the fixture has a lens or guard over it. Shatterproof or coated tubes are the usual spec in those spaces, and in food-handling areas as well.

The part is Satco S49935: 11 watt, 4 foot LED T8, medium bi-pin base, 3500K, 1800 lumens, Type A ballast dependent, in gloss white. It is a single configuration, so there is no finish or color temperature to select on the order.
