Philips Lighting 456979 – Frequently Asked Questions

1) Will the Philips 456979 R20 LED fit a standard R20 recessed can?
Yes. The 456979 is an R20 form factor with a 2.52 inch diameter and 3.917 inch overall height, so it drops into housings and track heads built for incandescent R20 reflectors. It threads into a standard E26 medium screw socket and runs on 120V line voltage.
2) Is the Philips 456979 R20 lamp dimmable, and what color does it dim to?
It is dimmable, and it is a warm-dim lamp: the color temperature range is 2200K to 2700K, so it starts at 2700K warm white at full output and shifts toward 2200K amber as you dim it. That is the behavior people expect from an incandescent on a dimmer, which is why it suits hospitality and residential accent lighting.
3) Is the Topaz LP16630K a drop-in substitute for the Philips 456979 R20 lamp?
They are different reflector sizes. The Philips 456979 is an R20 reflector lamp at 2.52 in diameter, 6W, E26 base, 450 lumens, and a 2200K-2700K warm white output. The Topaz LP16630K is a dimmable PAR16 lamp at 3000K. PAR16 has a smaller face and a harder-edged beam than an R20, and 3000K reads cooler and less amber than a 2200K-2700K lamp, so in a run of recessed cans that already uses R20 the two will not look the same side by side. Both are dimmable.
4) I need a dimmable LED for a track head but the fixture takes a different bulb shape than R20. What else works?
The Philips 456979 is only made in the R20 reflector form with an E26 medium screw base. If the fixture needs another shape, the Sylvania Ultra LED series is a dimmable LED lamp line offered in multiple shapes, so you can keep dimming control while matching the socket and envelope the fixture actually accepts. Confirm the shape and base against the fixture before ordering.
5) How bright is the 456979 R20 LED compared to the incandescent R20 it replaces?
It puts out 450 lumens, which is in the range of a 40W to 45W incandescent R20. If you are coming off a 50W incandescent R20 you will notice a modest drop in output, though the beam character is similar because the reflector shape is the same.
6) Can I mix the 456979 R20 with 2700K LEDs already in the other cans?
At full brightness it reads as warm white near 2700K, so it will blend reasonably with fixed 2700K lamps. Once you pull the dimmer down it warms toward 2200K while the fixed lamps stay at 2700K, so on a shared dimmed circuit you will see a color mismatch. For a uniform look across a run, use the same lamp in every socket on that circuit.
7) Is 80 CRI good enough for retail display or hospitality lighting?
The 456979 is an 80 CRI lamp, which covers general ambient, corridor, and guest room lighting fine. For merchandise where color accuracy sells the product, such as apparel, cosmetics, or food, buyers typically specify 90 CRI or better, so this one is better suited to general-purpose and accent use than to critical display.
8) What is the difference between an R20 lamp and a PAR16 or A19 LED?
R20 is a short reflector with a flood-type spread, sized at 2.52 inches across, meant for small recessed cans and track in residential and light commercial work. A PAR16 such as the Topaz Lighting LP16630K is a smaller pressed-glass reflector with a tighter, more controlled beam for accenting. An A19 like the Sylvania 79292 Contractor Series is an omnidirectional household shape with no reflector, so it is for table lamps and open fixtures rather than directional cans.
9) What other dimmable LED lamps could I use if I need a different shape or output?
If the R20 shape is not what the fixture takes, the Sylvania Ultra LED Series is a dimmable line offered in multiple lamp shapes, and the Topaz LP16630K is a dimmable PAR16 at a fixed 3000K if you want a cooler, more neutral white and a tighter beam instead of the 2200K-2700K warm dim of the Philips R20.
10) For a rental unit I just need general ceiling light, not accent lighting. Is the Philips 456979 the right lamp or is there a simpler option?
The 456979 is a directional R20 reflector that throws light forward, which suits recessed cans, track heads, and accent or display work. For an open fixture or a bare socket that needs light spread in all directions, an A-shape lamp is the usual choice: the Sylvania 79292 is an A19 Contractor Series LED lamp at 14 watts, 2700K warm white. It is a non-reflector bulb, so it is not an alternative inside a can where you want a controlled beam.
11) Which lamp holds a warmer color at low dim levels, the Philips 456979 or the Sylvania 79292?
The Philips 456979 is specified at 2200K-2700K warm white and is a dimmable lamp, so its range reaches lower and more amber than a fixed-point lamp. The Sylvania 79292 A19 Contractor Series LED is specified at 2700K. If you are matching a dining room or hospitality space that already dims to a candle-like amber, the 456979's 2200K end of the range is the closer match; if every other lamp on the circuit is a flat 2700K, a fixed 2700K lamp will blend more predictably.
12) I am standardizing a building on one dimmable LED lamp. Does the Philips 456979 cover it or do I need a second part number?
The 456979 covers R20 sockets only, at 6W, E26, 450 lumens, 120V, with an 80 CRI warm white 2200K-2700K output. Most buildings have more than one lamp shape in the mix, so expect a second part number for the non-reflector positions. The Sylvania Ultra LED series is a dimmable line built in multiple shapes, and the Sylvania 79292 Contractor Series covers A19 positions at 2700K. Keeping color temperature consistent across whichever parts you pick matters more to the look of a corridor than the brand on the lamp.
13) Will this LED R20 be too heavy for old track heads and sockets?
No. The lamp weighs 0.196 lb, far less than a glass incandescent reflector, so it puts very little strain on aging track head sockets or spring clips in old cans.
14) Is the Philips 456979 R20 a clear or frosted lens?
Frosted, with a white body, so the diffused face softens the source and keeps glare down in open cans and track heads where the lamp is visible from below.
