LED A19 Bulb
What is an A19 bulb?
A19 bulbs are standard screw in bulbs designed to be the direct replacement to your existing incandescent and CFL bulbs. Providing the same brightness at a fraction of the energy consumption as your old incandescent bulb, A19 bulbs are the cost-effective alternative. These bulbs feature a variety of color temperatures for any of your lighting needs.
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 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 color temperature do I need?
Color temperatures 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 is the difference between Directional and Omni-Directional?
- Directional bulbs are typically used for recessed cans or any place where a directional light source is needed.
- Directional bulbs feature a 180 degree beam angle so no light is wasted.
- Omni-Directional LED A19 bulbs allow for light to go in all directions with a 300 degree beam angle.
- Omni-Directional LED Bulbs are perfect for table lamps utilizing a lamp shade.
What wattage equivalent do I need?
| LEDs (Watts) | CFLs (Watts) |
|---|---|
| 4-5 | 8-12 |
| 6-8 | 13-18 |
| 9-11 | 18-22 |
| 12-14 | 23-31 |
| 15-22 | 32-54 |
What incandescent bulbs do A19 bulbs replace?
A19 LED bulbs can easily replace a 40W or 60W incandescent bulb.
For example:
- A 7W A19 LED bulb will replace a 40W incandescent, with a lumen output ranging from 400-500 lumens.
- A 10W A19 LED bulb will replace a 60W incandescent, with a lumen output ranging from 800-900 lumens.
A good rule of thumb to figure out your LED replacement is to look at the lumens (desired brightness), and find a bulb that works accordingly.
