This product is a standard A21 LED screw-in lamp designed to work in virtually all lamp fixtures, including those designed for traditional incandescent or CFL lamps.
The lamp has an industry-standard E26 base, which is the ubiquitous, approximately 1-inch wide, screw-base.
The lamp emits the equivalent brightness of a 100 watt incandescent bulb, but only consumes 15 watts. You may find that your lamp fixture has a warning regarding the maximum wattage permitted per socket. Use the 15 watt value, and not the 100 watt equivalency value, in confirming compatibility.

WARM & RELAXING
Our CENTRIC HOME™ bulbs are offered in 2700K and 3000K color temperature options. Both options provide a warm and relaxing environment, perfect for home and hospitality applications.
2700K light is very similar to the warm glow emitted by a traditional incandescent light bulb. 3000K, on the other hand, still provides a relaxing and warm environment, but is slightly less yellow, which may be preferred for locations that are more task-oriented, such as reading and dining. Learn more here.
Both color temperature options feature 95 CRI, which ensures that the light spectrum is a near-perfect replication of traditional incandescent and halogen bulbs.
FLICKER-FREE & HEALTHY
Some LED lights will produce rapid flicker or pulses that aren't immediately visible to the naked eye, which can cause headaches, nausea and eye strain. Our CENTRIC SERIES™ products include additional electrical circuitry to achieve a truly flicker-free light output that produces a comfortable and stable light level.

What is the difference between 2700K and 3000K?
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.

Should I get daylight white (4000K - 6500K) bulbs instead?
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.
Do these bulbs emit blue light?
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.
How many bulbs should I install in my space?
We generally recommend using one bulb for every 75 square feet of space. Simply divide the square footage of your space by 75 to get the number of bulbs needed. For example, a 150 square foot area would require 150 divided by 75, or 2 bulbs.
For more guidance, we recommend checking out our lumen estimation calculator.
Are these bulbs dimmable?
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.
Do these bulbs emit any UV radiation?
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).
What kind of lamp fixture can this product be used in?
These A21 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 A21 type, these bulbs will be compatible.
Although these lamps have the brightness of 100 watt incandescent lamps, these lamps have an actual power draw of only 15 watts. Therefore, they can safely be used in fixtures that have a max rating of less than 100 watts.
What is the voltage range of these lamps? Can they be used overseas?
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.
I have installed waveform lights throughout my home and office and I am so happy with their products and customer service.
I used these 2700K A21 bulbs for replacements to 100 watt incandescent bulbs I had in my barn lights in my finished garage. The incandescent bulbs weren't lasting more than 8 months and the big box store led's were not much better. I had originally installed led bulbs in the lights and hated the color and poor quality of them so much I switched back to incandescent. They were name brand bulbs too, I tried them all and wasted hundreds of dollars. They would be good for a while and then start flashing and flickering and driving me up a wall. The color on these bulb is superior to any other brand I have tried and I will be replacing all my other bulbs with Waveform Lighting bulbs.
Good quality and color rendering; zero startup time. Bought two to test, will be buying more.
Great bulbs so far. Light output (lumens) 50% greater than the 60 Watt halogen bulbs we were using, while using 75% less energy. We also prefer the color temperature (3,000 K) as well. These bulbs are pricey, but if they last as long as claimed, they are well worth the initial expense.
I do a lot of detailed work and these are excellent for that. Seems to reduce eye strain and other issues I've had with other LED bulbs. I also use them for product photography and it is nice to know that setting white balance to the temp of the light will give me accurate colors.
