Philips Lighting 577841 BR40 LED Lamp, 13.3-Watt, 90 CRI Warm Glow

The Philips Lighting 577841 is a BR40 LED lamp built for reflector-style downlighting and recessed fixture applications that call for smooth, high-quality warm light. Rated at 13.3-Watts, this lamp delivers 1204-Lumens initial output through a standard E26 single contact medium screw base, making it a direct-fit upgrade for existing BR40 sockets. With a 90 CRI rating, the 577841 renders colors accurately and naturally, while its signature Warm Glow dimming effect shifts color temperature from 2700K down to 2200K as the lamp is dimmed, replicating the familiar warm-down behavior of incandescent and halogen BR40 lamps. This combination of high lumen output, high color rendering, and Warm Glow performance makes the 577841 well suited for residential and light commercial spaces where ambiance and color accuracy both matter.

Key Features

Philips Lighting 577841 – Frequently Asked Questions

1) Will the Philips 577841 BR40 LED fit a standard 6-inch recessed can?
The 577841 is a BR40 reflector lamp measuring 4.567 inches across and 6.299 inches in overall length, with an E26 medium screw base. BR40 lamps are sized for 6-inch and larger recessed housings; in a 5-inch can the 4.567 inch diameter will not seat properly. Measure the aperture and housing depth before ordering, since the 6.299 inch length has to clear the socket and trim.
2) What incandescent BR40 wattage does the Philips 577841 replace?
At 13.3 watts the 577841 puts out 1204 lumens, which lands in the range a 65 to 75 watt incandescent BR40 produced. It screws into the same E26 medium socket, so it is a drop-in swap for an existing BR40 floodlamp with no fixture change.
3) Does this Philips BR40 dim, and does the color change when you dim it?
Yes, and that color shift is the point of it. The 577841 uses the Philips Warm Glow effect: it runs at 2700K at full output and drops toward 2200K as you dim, the same warm-down behavior a halogen or incandescent BR40 had. If you want a fixed color temperature all the way down the dimming curve, this is the wrong lamp.
4) Can I mix the 577841 Warm Glow with standard 2700K LED downlights in the same room?
Not without it showing. At full output the 577841 reads 2700K and will match, but as soon as the dimmer comes down it warms to 2200K while a fixed 2700K lamp stays put, so you get visible color mismatch across the ceiling. For a run of cans on one dimmer, lamp them all with Warm Glow or all with fixed-CCT lamps.
5) Is 90 CRI enough for retail display or hospitality lighting?
The 577841 is rated 90 CRI, which is the usual threshold specified for hospitality interiors, retail merchandise, and anywhere finishes, wood tones, and skin tones need to read correctly. Standard LED downlight lamps often sit at 80 CRI; this one is a step up for spaces where color accuracy is part of the spec.
6) What else does ZenSupply carry if I need a smaller LED lamp instead of a BR40 flood?
The BR40 is a wide flood for 6-inch and larger recessed cans. For tighter accent work in a small aperture, the Topaz Lighting LP16630K is a dimmable PAR16 LED at 3000K. For general open-fixture and table-lamp duty rather than reflector downlighting, the Sylvania 79292 is an A19 Contractor Series lamp at 14 watts, 2700K. Neither of those gives the 2200K Warm Glow dim-to-warm behavior the Philips has.
7) Will the Philips 577841 work in an existing fixture with a medium socket and no other changes?
Yes. It uses an E26 single contact medium screw base, the standard North American socket, so it goes straight into an existing BR40 or incandescent flood socket with no adapter, no driver, and no fixture rework. The only thing worth checking is that the dimmer on the circuit is LED compatible.
8) We need dimmable LED lamps in several shapes across one building - can we standardize instead of buying the Philips 577841 for every socket?
The Sylvania Ultra LED Series is a dimmable LED family offered in multiple shapes, which lets a facility carry one series across mixed socket types. Where the opening is specifically a BR40 recessed can and the space needs high color fidelity, the Philips 577841 covers it at 13.3W, 1204 lumens, 90 CRI on an E26 medium base, with the 2200K/2700K Warm Glow dim-to-warm behavior that mimics the halogen BR40 lamps being replaced. A common approach is the Ultra LED Series for general sockets and the 577841 for the downlights where guests and tenants see finishes and skin tones.
