SATCO Lighting S29859 9W LED PL 4-Pin, 3500K, 1050 Lumens, G24q Base, 50000 Avg Rated Hours, Type A, Ballast dependent

Yes, that is exactly what this lamp is for. The S29859 is a Type A, ballast-dependent LED PL lamp, so it runs off the existing fluorescent ballast with no rewiring. The ballast has to be a working 4-pin ballast; if the ballast is dead or you plan to remove it, you need a ballast-bypass (Type B) lamp instead, not this one.

No. This PL lamp is non-dimmable. On a dimmed circuit you will get flicker, buzz, or no start at all, and you can damage the lamp or the ballast. Put it only on full-on switched circuits. It also has no three-way function.

Yes. The S29859 is an enclosed-rated lamp, so it is approved for fixtures with no ventilation, which many LED retrofits are not. It is also damp location rated, so covered exterior entries, parking garage soffits, and bathrooms are fine. It is not wet location rated, so keep it out of direct spray or rain exposure.

No on both counts. This PL lamp is not DLC listed, so it will not qualify for utility rebate programs that require a DLC entry, and it is not BAA compliant, so it is not eligible for Build America, Buy America federally funded work. It is FCC compliant and is country of origin China.

The 9W S29859 puts out 1050 lumens, which covers the common 18W and 26W 4-pin CFL output range in a downlight or sconce. Satco rates it against a 40W incandescent for equivalence. Light output is spread wide at a 120 degree beam angle through a frosted lens, so it reads as general ambient light rather than a spot.

3500K is a neutral white, between the warm 2700K/3000K of residential lamps and the cooler 4000K common in offices and corridors. If your corridors and common areas are already 3500K, this matches. Note the S29859 is a fixed 3500K lamp, not field-selectable, so you cannot dial it to another temperature on site. Color rendering is 82 CRI, which is standard for commercial PL retrofits.

Yes. The S29859 is rated 120V to 277V at 50/60Hz, so it covers both 120V residential-style branch circuits and 277V commercial lighting panels. Current draw runs 0.075 to 0.032A across that voltage range, which matters when you are totalling a retrofitted circuit.

No restriction here. The S29859 is rated for base up or base down operation, so the same lamp works in ceiling downlights, horizontal wall sconces, and table-level fixtures without derating.

The housing is white with a frosted lens, so it blends into a typical white downlight or sconce reflector. Each lamp weighs 0.23 lb, useful if you are costing out a bulk re-lamp shipment.
