What does A21 mean on a bulb?
A21 refers to the lightbulb's size and shape. A-series lightbulbs are the most recognizable lightbulb there is. The "A" refers to the bulb’s physical shape while the "21" simply refers to the bulb’s physical size, which is 2.625 inches in diameter. It’s always a good idea to check your light fixture to make sure the bulb will fit.
What color temperature do I need?
Correlated Color Temperatures (CCT) range from warm white to cool white.
- 2700K - 3000K – provides an ambient, intimate, and personal mood with its warm white light that is ideal for living rooms, family rooms, and hospitality environments.
- 3500K - 4100K – provides a clean and efficient neutral white light that is ideal for kitchen, bath, garage or commercial applications.
- 5000K - 6500K - provides a vibrant and alert cool white light that is ideal for commercial, industrial, and institutional applications.
What does it mean when a bulb produces an omnidirectional beam type?
Omnidirectional bulbs emit light in every direction: top, left, right and to the bottom of the bulb. Unlike traditional incandescent bulbs, A21 bulbs will produce light in all directions making them perfect for floor lamps, table lights, and other interior light fixtures.
What is a beam angle?
The beam angle of an LED bulb is the angular dimension of the cone of light from the lamp. It encompasses the central part of the beam out to the angle where the intensity is 50 percent of the maximum.
For most household ceiling-fitted applications, a beam angle of 30 or 40 degrees would be sufficient. For outdoor applications, a wider beam angle of 60 to 120 degrees is preferred to cover a larger surface area.
What is the equivalent to an A21 bulb?
An A21 Bulb is the equivalent to a 100 Watt incandescent bulb. These are great energy efficient replacements for incandescent bulbs for your home or office.
What's the brightest A21 bulb?
The brightness of a light bulb is measured in Lumens. That means that the higher the Lumen output, the brighter the bulb will be. The brightest A21 Bulb is a 2500 Lumen Bright White Bulb. You can learn more about The Anatomy of a Lightbulb here!
