Energy Used
A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
| 15 Watts |
Volts
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.
| 120-277 |
Base
The end (or ends) of the lamp that fits into the socket.
| Medium Bipin |
Wiring
Wiring configuration a bulb can work with. Can be single-ended, double-ended or both.
| Single Ended |
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".
| T-8 |
Bulb Color
The color of the light produced by a bulb
| Cool White |
CRI
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.
| 80 |
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).
| 4000 |
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.
| 1800 |
Bulb Finish
The surface finish of a bulb, which may affect the quality of the light emitted.
| Opaque |
Bulb Technology
The technology implemented by the bulb, e.g. incandescent, halogen, LED
| 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.
| 50000 |
Operating Temperature (°F)
The ambient temperature in which the product can safely operate.
| -20 to 120 |
Beam Angle (°)
The width of a light beam, expressed in degrees. The beam angle 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 angle of 25 degrees.
| 240 |
Bulb Power Type
Defines how a lamp is powered, whether it needs a ballast or not, or can use either
| Ballast Bypass |
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.
| 48 |
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.
| 1 |
Socket Type
Type of socket a linear lamp is compatible with, whether shunted, non-shunted or both.
| Non Shunted |
Warranty | 5 year limited |
Damp Location
Suitable for an exterior or interior location that is subject to condensation of moisture in, on or adjacent to electrical equipment
| Yes |

Rated for Fully Enclosed Fixtures
Not all LED bulbs are suitable for use in enclosed fixtures, due to the amount of heat they generate. Rated bulbs have been tested and approved as safe for enclosed fixtures.
| Yes |
Battery Backup
Has a backup battery to allow it to continue functioning in case of power failure.
| Yes |
