Philips Lighting

Energy Used

A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
Energy Used
20 Watts


A measure of "electrical pressure" between two points. The voltage specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 120 V) refers to the line voltage coming from the power source and is connected to the ballast.


The end (or ends) of the lamp that fits into the socket.
Medium (E26)

Bulb Shape

The description of the general appearance of a lamp/bulb consists of a letter(s) followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch. For example, a common household bulb is the A-19. The bulb is "A" shape and the diameter would be nineteen 8ths of an inch, or 2 3/8".

Bulb Color

The color of the light produced by a bulb
Bulb Color
Soft White

Color Temperature (Kelvin)

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).
Color Temperature (Kelvin)

Brightness (Lumens)

A rating of the inital light output of a bulb, rated after 100 hrs of operation. Lumens are a measure of how much light falls on one square foot of area, one foot away from the light source.
Brightness (Lumens)

Bulb Finish

The surface finish of a bulb, which may affect the quality of the light emitted.
Bulb Finish

Bulb Technology

The technology implemented by the bulb, e.g. incandescent, halogen, LED

Average Rated Life (hr)

A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.
Average Rated Life (hr)

Beam Spread (°)

The width of a light beam, expressed in degrees. The beam spread is often part of the ordering code for reflector lamps. For example, a 50PAR30/HIR/NFL25 is a 50-watt PAR30 narrow flood lamp with a beam spread of 25 degrees.
Beam Spread (°)

Class and Filament

A designation used to describe the shape or structure of the filament in an incandescent or halogen light bulb. Most commonly used for specialty products like rough service and antique replica lamps.
Class and Filament
C, CC-8

Length (in)

Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.
Length (in)

Diameter (in)

Light bulbs: a measurement of a bulb's width taken at the widest point of the bulb. Fixtures: the measurement across the widest point of a circular fixture.
Diameter (in)


Indicates whether a bulb can be dimmed in conjunction with a suitable dimmer control.

Product Notes: NO TRANSFORMER REQUIRED-Remove Old Bulb, Screw In This Bulb. Must Use Electronic Low Voltage (ELV) Dimmer For Dimming Applications. Also, Directional Light Output Measured Within the Beam is 1200 Maximum Beam Candle Power (MBCP) versus 1100 MBCP for a Typical Standard 50PAR20 Flood Halogen. Lumen comparision, while common, is not the best way to compare Spot/Flood/Focused light of any kind.

  • Q:

    I want to use this bulb in dimmable application. The product note says that you Must Use Electronic Low Voltage (ELV) Dimmer For Dimming Applications. I do not know if I have ELV Dimmer. I have a part number for the dimmers...LUTAY600PWH and LUTAY603PWH. Do you know if these are ELV dimmers? I am also thinking about switching to LED Bulbs. Are the LED8PAR20WW's dimmable? Can they be used in tracks with the halogen bulbs?

    I'd like to place an order today if possible. Thanks for the help.

      The particular dimmer part numbers listed are not considered Electronic Low Voltage Dimmers. They are available, however we do not carry them. Regarding the LED bulb LED8PAR20WW, this item is non-dimmable. We offer a number of dimmable LED's that can be found on our website. If an LED product is chosen, it would be best to contact our customer service department to make sure they are compatible with the referenced dimmers.
