Philips EnduraLED Brand DIMMABLE 17 Watt narrow flood lamp generates as much light as many 75 Watt halogen lamps. Can smoothly dim down to 10% power.

  • Perfect to use anywhere you are using a 75 Watt PAR38 halogen lamp

  • No lead or mercury means easy and environmentally safe disposal

  • 1050 Lumens initial light output is comparable to most 75 Watt halogen lamps, while saving 58 Watts in electricity

  • VERY long life - rated to still put out 70% as much light after 45,000 hours of operation as it does when brand new

Also, NOT RECOMMENDED for use in enclosed fixtures because heat buildup can shorten life.  DO NOT "hot swap" this lamp.  Turn off fixture before replacing existing bulb.

Energy Used

A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
Energy Used
17 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

Cool White


Color Rendering Index is an international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.

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 initial 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)

Center Beam Candle Power

Center Beam Candle Power(CBPC), or Maximum Beam Candle Power(MBCP), represents the intensity of delivered light that falls onto a surface area. Delivered light describes how much useful light a bulb can deliver to a task area and is the best and most relevant measurement for evaluating LEDs and for making accurate comparisons with conventional lighting. Evaluating an LED solely or primarily on the basis if its lumen output can underestimate or otherwise give a distorted picture of the LED's performance and suitability for a given task or application.
Center Beam Candle Power

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 (°)

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: Excessive or Continuous Heat Build-up will Drastically Reduce the Life of LED Products. Well Ventilated AND Open Fixtures Are Required for Proper Light Output and Product Life. DO NOT HOT-SWAP THIS BULB-Turn Off Power To Fixture Before Installation.

    Comments about Philips Lighting Company 17Watt, 120 Volt DIMMABLE 45,000-Hr Cool White LED PAR38 Bulb:

    The Philips 17 watt PAR38 LED (930 lumens) seemed to deliver an amount of light similar to a halogen 75PAR38 narrow flood (1,050 lumens). The light cast from the LED seemed a bit more uniform than the halogen which has some of its light distorted by its lens. This 4000K version is quite a bit whiter than the halogen bulbs it's intended to replace. That said, users who prefer a cleaner/white light than that provided by a halogen source may find this to their liking.

    Since this LED has a color temperature that is much higher (whiter) than halogen it's important to consider if replacing bulbs individually will create a situation where there is a dramatic inconsistency from one fixture to another – your best approach might be to try a few LEDs to determine if this causes an issue.

    As always, dimming seems to be adequate though we recommend that users considering to put several LEDs on an existing dimming system proceed with caution and test the load ratings on their system to be sure the replacement LEDs are drawing enough current to allow the dimmer to do its job.
