SATCO Lighting S49934 11W, 4 Foot LED T8, Medium Bi Pin Base, 3000K, 50000 Avg Rated Hours, 1800 Lumens, Type A, Ballast dependent

Yes. The S49934 is a Type A, ballast dependent 4 foot LED T8, which means it runs off the fixture's existing fluorescent ballast. Drop it into the medium bi-pin tombstones and you're done, no rewiring and no ballast bypass. The trade-off is that the tube's life is tied to that ballast, so if the ballast fails the tube stops working until it's replaced. Crews doing a full retrofit who want the ballast out of the picture should be specifying a Type B (direct wire) tube instead.

It will. The tube measures 48 inches with a medium bi-pin base at each end, the same form factor as a standard F32T8 lamp, so it seats in the existing lampholders of a 4 foot troffer, wrap, or strip fixture.

3000K is a warm white, closer to the tone of an incandescent or a residential warm LED. It will not match 4100K cool white or 5000K daylight tubes, and mixing them in the same room or the same fixture is visibly obvious. If you're standardizing a building, pick one color temperature and change out whole rooms at a time rather than tube by tube. Color rendering is 80+ CRI.

No extra parts. A Type A tube uses the fluorescent ballast and lampholders already in the fixture, so there are no non-shunted tombstones to install and no wiring changes. All you need is a working T8 ballast in the fixture. If the ballast is already failing, replace it or go with a direct-wire Type B tube instead of putting a new lamp on a dying ballast.

1800 lumens at 11 watts. A 32 watt T8 fluorescent typically runs higher output than that, so in a space where light levels are already tight (warehouse aisles, task areas) a one-for-one swap can read dimmer. For corridors, offices, back-of-house and multi-family common areas it's generally fine, and you're drawing 11 watts instead of 32.

The tube is listed as dimmable. Keep in mind it's a Type A lamp running on the fixture's fluorescent ballast, so dimming performance depends on that ballast being a dimming ballast and on the control wired to it. On a standard non-dimming instant-start or programmed-start ballast, it runs at full output.

Glass. That matters for food service, healthcare and education specs where a coated or plastic-bodied lamp is often required over open food prep or in patient areas. For general office, corridor and back-of-house fixtures glass is standard. The tube weighs 0.4 lb, so it's no heavier on the lampholders than the fluorescent it replaces.

Country of origin is China. Buyers working to a domestic-preference or Buy American requirement on a federal or institutional job should plan around that.
