SATCO Lighting S11742 9.5W, 4 Foot, T8 LED, Medium bi-pin Base, 4000K, 50000 Avg Rated Hours, 1740 Lumens, Type A, Ballast dependent

Yes. The S11742 is a Type A, ballast-dependent lamp: it runs off the existing fluorescent ballast and drops into instant start and rapid start ballasts with no rewiring. One caveat worth taking seriously on a building-wide relamp: it will not work with every ballast, so check the ballast compatibility chart against the ballast model in your fixtures before you commit to a large quantity.

The lamp draws 9.5 watts at the lamp and delivers 1740 lumens, versus the 32 watts a standard F32T8 fluorescent pulls. Current draw is 0.079 to 0.034A depending on supply, over a 120V to 277V range at 50/60Hz. Bear in mind that on a Type A install the existing ballast stays in circuit and still consumes some power, so actual fixture wattage runs slightly above the lamp rating.

4000K is neutral white, the usual choice for offices, corridors, retail back-of-house and warehouses where you want a clean, non-yellow light. This lamp is fixed at 4000K, not field selectable, so every tube out of the box matches. CRI is 82. If you are patching into an existing space, match the color temperature of the tubes already in the ceiling or the mismatch will be obvious across a run of troffers.

It is rated for indoor, damp locations. That covers covered walkways, bathrooms, kitchens and similar damp interior spaces, but not wet locations or direct exposure to weather. For an open parking deck or anywhere rain reaches the fixture, you need a wet-location rated lamp and enclosure.

The lamp is listed as dimmable, but it runs ballast dependent, so dimming behavior is controlled by the fluorescent ballast and its control system, not by the lamp. On a standard non-dimming instant start or rapid start ballast it will simply run at full output. Because compatibility varies by ballast, verify your dimming ballast against the compatibility chart before specifying it into a controlled space.

Order Satco S11742. It is a 9.5W, 4 foot, 4000K, 1740 lumen T8 LED on a medium bi-pin base, Type A ballast dependent, with a white housing and gloss finish. Rated equivalent to a 75W incandescent in output terms.

Beam spread is 210 degrees, so output is directional rather than the full 360 degrees a fluorescent tube throws. In a troffer or strip fixture that works in your favor, since light that used to bounce off the reflector now goes straight down. In a fixture where you want uplight, such as an indirect pendant, expect the ceiling wash to drop off.
