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.

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".

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.

Bulb Finish

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

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)

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.

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

Krypton bulbs are brighter


Last year we renovated our master bathroom and installed sconces on either side of the make-up mirrors. We could only get 40W incandescent bulbs for the sconces we liked. After using these bulbs for a while, we decided that we needed brighter lights for this purpose. After reviewing many possible replacement bulbs, including LED, I happened upon the Bulbrite brand Krypton decorative bulbs, read its existing 5-star review, and noted that these bulbs were rated about 30% brighter (480 lumens) than most other candelabra bulbs. These bulbs were just the ticket and are considerably brighter than regular candelabra bulbs.

Bright 40watt chandelier bulb


I could not find 40watt bulbs that burned as brightly as the one I needed to replace in my multi-bulb chandelier. Other 40watt bulbs that I tried looked dull in comparison. After looking on the internet, I learned to look for the lumen output. These krypton bulbs were just the trick. All 40 watt chandelier bulbs are not the same. If you want bright, clear light, this bulbs for you.

what is krypton? I noticed the price on this bulb is more than double similar bulbs. What makes krypton special? Am not sure how to evaluate it - -

This bulb contains Krypton gas. Krypton bulbs emit a whiter light, are more efficient because they produce higher lumens at lower wattages and create less heat than a standard halogen or incandescent bulb.
