Frequently Asked Questions
- Can LEDs be used with dimmers?
Usually, yes. Many LEDs are specifically listed as being dimmable. Some dimming systems work with LEDs better than others, so it's best to test one or two before completely re-lamping a space.
- What is the difference between a floodlight and a spotlight?
Led spot lights output a narrower beam of light, typically less than 45 degrees wide. Most of the light from a spotlight is concentrated onto a relatively small area producing a bright spot. Led floodlights output a wider beam of light, up to 120 degrees, so the light from a floodlight is spread out over a much larger area.
- How to restore the factory Settings
Power off, press “Mode”and “Setup”two buttons together then power in, After 3 seconds let it go.
- What's the quality of LED light?
If you buy quality product, the light quality is excellent. Color Rendering Index (CRI) is generally used to measure light quality on a scale from 1-100. Most LEDs have a CRI rating of at least 80, and many are rated 90 and above.
- What do "cool white" and "warm white" mean, and what is CCT?
The Color Correlated Temperature (CCT) is given in the description of each of our white led bulbs.
By comparison, a typical incandescent bulb has a CCT of 2800K. A typical halogen is a bit higher, maybe 3500K. Daylight white is 4500K and a cool white fluorescent is 6000K or more.
The human eye adapts to background light so that even a daylight white bulb will look slightly blue in a room illuminated mainly with incandescent bulbs. Similarly, an incandescent bulb will look very yellow or even orange in midday sunlight.
