SATCO Lighting S11580 5.5W PAR20 LED, Medium Base, Silver Finish, CCT Selectable, 120V, 25 degree Beam Angle

Yes. The S11580 PAR20 is wet location rated and listed for indoor and outdoor use, so it can go in exterior soffit cans, canopies, and covered entry fixtures that see direct weather. It also mounts in any orientation, base up or base down or horizontal, which matters for wall wash and soffit fixtures.

One part covers five color temperatures: 2700K, 3000K, 3500K, 4000K and 5000K, selected on the lamp itself. For a property manager or MRO buyer that means a single stocked item for warm residential corridors at 2700K or 3000K, neutral retail and office at 3500K or 4000K, and cool utility or garage areas at 5000K. You are not ordering a different SKU per space.

Yes, it replaces a 50W halogen PAR20 and pulls 5.5W to do it, at 500 lumens. Draw is 0.078A per lamp, so a 15A 120V circuit is nowhere near a limiting factor on the count of fixtures you can put on it, which is the usual reason people re-lamp a whole run of track or cans at once.

25 degrees is a narrow flood. It puts a defined pool of light on artwork, signage, merchandise displays, or a lobby feature wall, and it works for high ceilings where you want the light to reach the floor without spilling. For general room fill or evenly washing a corridor ceiling, a wider flood PAR20 is the better choice; this one will read as scalloped and spotty if you space it like a general lighting lamp. The lens is clear polycarbonate, which keeps the beam edge crisp rather than diffused.

The lamp is dimmable on 120V line voltage. It is not a three-way lamp, so it will not step through levels in a three-way socket, and it needs an actual dimmer to control output. As with any LED retrofit onto an older halogen dimmer, the dimmer has to be one rated for LED loads.

The S11580 renders at 90 CRI, which is the threshold most retail, gallery, hotel lobby, and healthcare specs call for when color accuracy on merchandise, artwork, or skin tone matters. Paired with the 25 degree narrow flood, that is the accent-lighting combination: tight beam, accurate color. For back of house or a parking garage, 90 CRI is more than the job needs.

Rated 25,000 hours. On a retail or lobby schedule of roughly 12 hours a day that is about five and a half years of service, which is why these get specified for high ceilings, stairwells, and any fixture where the lift or the lamp change is the real cost rather than the bulb.

Silver is the housing color, the visible body of the lamp, not the reflector performance. It matters where the lamp is visible in an open track head, a monopoint, or a shallow can with no trim covering the lamp body, and buyers pick it to match brushed nickel and aluminum fixture hardware. The housing is polyamide and the lens polycarbonate, so it is an all-plastic body, no glass to break in a track head that gets aimed and re-aimed.

It is lawful for sale in California, and it is FCC compliant, which is the electromagnetic interference declaration facility and institutional specs typically ask for on an LED lamp.
