SATCO Lighting S29761 27W, LED PAR38, 4000K, 40 degree Beam Angle, Medium Base, 100-277V

The S29761 PAR38 lamp runs on 100-277 volt input, so it drops into 120V residential circuits and 277V commercial lighting branch circuits without a different part number. That matters if you are relamping a building where the common areas or exterior fixtures are fed at 277V and the units are at 120V, since one lamp covers both.

Yes, in the same medium base socket. At 27 watts it draws a fraction of what a 90W to 120W halogen PAR38 pulls, and the PAR38 envelope means it seats in the same trim and aperture. The two things to check before you commit a fleet order are dimmer compatibility on any dimmed circuit and whether you want the 4000K neutral white this lamp produces, which will look noticeably cooler than the halogen it replaces.

4000K is neutral or cool white, a clean, slightly blue-leaning light rather than the yellow of a 2700K incandescent. It reads well in parking garages, stairwells, corridors, warehouses, retail, and shop or service areas where people want the space to look bright and awake. For apartment interiors or hospitality lobbies where a warm look is expected, a 2700K or 3000K PAR38 is the better match.

Order Satco S29761. That is the manufacturer part number for the 27 watt LED PAR38 at 4000K with a 40 degree beam and a medium base, and it is the number to put on a purchase order or hand to a counter when standardizing a lamp across a facility.
