SATCO Lighting S49937 11W, 4 Foot LED T8, Medium Bi Pin Base, 5000K, 50000 Avg Rated Hours, 1800 Lumens, Type A, Ballast dependent

No rewiring. The S49937 is a Type A lamp, which means it operates off the fixture's existing fluorescent ballast, and the spec data lists it as ballast required. Pull the old F32T8 lamp, drop this one into the same medium bi-pin sockets, and it lights. If the ballast is dead or you want to eliminate it, a Type A lamp is the wrong choice.

Yes. At 48 inches long with a medium bi-pin base and a T8 shape, it drops into the same lampholders as a standard 4 foot T8 fluorescent tube. Burning position is universal, so it works in surface strips, wraps, troffers, or a vertical mount.

At 11 watts it puts out 1800 lumens at 5000K, with a CRI of 82 and a 210 degree beam spread. That is noticeably less output than a typical 32W T8 fluorescent, so in a two or four lamp troffer over a workspace you may see a drop in light level. It suits corridors, stairwells, storage, and garages where the goal is cutting load. For task-level office lighting, step up to a higher-lumen T8.

It is DLC approved and listed as Title 24 compliant, which is what most utility prescriptive rebate programs and California nonresidential energy code paperwork ask for. It is also FCC compliant for EMI.

It is a fixed 5000K daylight tube, not color selectable, so it will match other 5000K lamps and will read visibly cooler and bluer next to 3500K or 4100K tubes. If you are relamping one fixture in a row, relamp the whole row or confirm the existing color temperature first.

It is rated for indoor use with a damp location rating, so covered and humid indoor spaces are fine, including enclosed stairwells and covered garage bays. It is not a wet location lamp, so keep it out of anything exposed to direct water or weather.

The lamp itself is listed as dimmable, but because it is a Type A tube the dimming is handled by the fluorescent ballast in the fixture. You need an existing dimming ballast for it to dim; on a standard instant-start or program-start non-dimming ballast it will run at full output only.

It operates across 120V to 277V at 50/60Hz, drawing 0.092 to 0.040 amps depending on supply voltage, at 11 watts. That range covers standard 120V commercial branch circuits and 277V lighting circuits in larger buildings.

The S49937 is a glass tube with a gloss white lens and a white housing, weighing 0.4 lb. Glass construction means it handles like a traditional fluorescent lamp and should be treated the same way for breakage and disposal on site; shatter-resistant coated or plastic-bodied tubes are the usual choice for food service and healthcare areas.
