CENTRIC HOME™ Flicker-Free A19 10W LED Bulb

These color temperature options correspond to the various shades of natural light. 2700K is a light color that best approximates the warm glow of traditional incandescent bulbs, while 3000K provides a bit more of a crisp and brighter white.

The choice between these colors is completely up to you! There is no correct answer, and this is a question of preference.

Regardless of your choice, both color options feature 95 CRI and flicker-free light output, which will provide you with a healthy and relaxing environment.

The most popular color temperature option for home and residential use is either 2700K or 3000K, commonly labeled warm white. These are the color temperatures that match the warm and inviting glow of traditional incandescent bulbs. 

Some people prefer daylight or neutral white color temperatures as they offer a more balanced spectrum that eliminates the orange and yellow tint seen in warm white color temperature bulbs.

If you're looking for a bulb that produces a crisp, energizing white light, we would recommend our CENTRIC DAYLIGHT™ product line, which offers the same 95 CRI and flicker-free performance but with daylight white color temperatures.

As with virtually all light sources, the CENTRIC HOME™ LED bulbs do emit some blue light.

You may have read or heard about the concerns regarding the blue light hazard. Excessive blue light exposure during evening hours is certainly a concern, but blue light is an essential and important part of our daily lives, as it is extremely abundant in natural daylight (the blue sky!) and an important signal to our bodies and circadian rhythms.

The CENTRIC HOME™ bulbs have a M/P ratio of approximately 0.5, which is inline with traditional incandescent and halogen bulbs.

It is also important to keep in mind that time of day, exposure time and distance away from the bulbs also have a significant influence on whether or not the blue light wavelengths will impact your circadian cycle.

We generally recommend using one bulb for every 40 square feet of space. Simply divide the square footage of your space by 40 to get the number of bulbs needed. For example, a 160 square foot area would require 160 divided by 40, or 4 bulbs.

Unfortunately, these bulbs are not dimmable. This means that they cannot be used on any electrical circuit which has a dimmer installed, even if you keep the dimmer at the maximum setting at all times.

These bulbs do not emit any ultraviolet radiation. The light output covers the entire visible spectrum between 420 nanometers and 800 nanometers, but does not go below (UV-A) or above (infrared).

These A19 bulbs have a standard screw-in base (E26 / E27), which is the same type that has been used for more than a century.

As long as the lamp fixture is designated for an A type or A19 type, these bulbs will be compatible.

Although these lamps have the brightness of 60 watt incandescent lamps, these lamps have an actual power draw of only 10 watts. Therefore, they can safely be used in fixtures that have a max rating of less than 60 watts.

The voltage range of this product is AC 90-240V and 50-60 Hz, which covers all global voltages. As such, they can safely be used internationally without any issues. The internal circuitry adjusts for the input voltage automatically, and does not affect the light output or performance of the lamp.
