Frequently Asked Questions
What is the single biggest advantage of an LED bulb over an incandescent bulb?
What is the single biggest advantage of an LED bulb over an incandescent bulb?
The single biggest advantage is Energy Efficiency and Longevity. An LED light bulb uses up to 90% less energy than an incandescent to produce the same brightness (lumens) and can last 15-25 times longer.
What is Kelvin (K), and why is it important when choosing light bulbs?
What is Kelvin (K), and why is it important when choosing light bulbs?
Kelvin (K) is the unit used to measure the color temperature of the light. Lower numbers (2700K) mean a warm, yellowish light (cozy ambiance), and higher numbers (5000K) mean a cool, bluish-white light (task clarity).
What does the number in the bulb name (A19, BR30) mean?
What does the number in the bulb name (A19, BR30) mean?
The number (e.g., 19 or 30) refers to the maximum diameter of the lightbulb at its widest point, measured in eighths of an inch. For example, an A19 is 19/8ths of an inch wide.
Do all LED bulbs work on my existing dimmer switch?
Do all LED bulbs work on my existing dimmer switch?
No. LED bulbs must be explicitly rated as "Dimmable." You must also ensure you replace your old mechanical dimmer with an LED-compatible dimmer for smooth dimming performance without flickering.
What is a Lumen, and how does it relate to Watts in LED lighting?
What is a Lumen, and how does it relate to Watts in LED lighting?
A Lumen (lm) is the measure of the brightness of a lightbulb. A Watt (W) is the measure of energy consumption. When shopping for LED light bulbs, you should choose based on the required Lumens, not Watts.
