  • Installation

    This product is a standard A19 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.

  • Frequently Asked Questions

    • 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.



    • 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 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 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.
    • Is this bulb available in an E27 base?

      These bulbs are currently available in an E26 base only. They can be used with global input voltages (see above), but we recommend exercising caution if used with E27 fixtures.



    • How does this A21 bulb compare to the A19 version of the CENTRIC HOME™ bulb?

      This product is the higher-brightness version of the CENTRIC HOME™ Flicker-Free A19 10W LED Bulb. The differences are as follows:

      Brightness - this A21 bulb emits 1600 lumens, which is equivalent in brightness to a 100 watt incandescent bulb. The A19 bulb emits 800 lumens, which is equivalent in brightness to a 60 watt incandescent bulb.

      This bulb emits two times the brightness compared to the A19 bulb.

      (Incandescent bulb equivalence values are not exactly double, due to the fact that incandescent bulbs improve in efficiency at higher power levels).

      Power - to achieve the higher brightness level, a higher electrical power input is required. As a result, the power draw for the A21 bulb is rated at 15 watts, compared to the A19 bulb which is rated at 10 watts.

      The A21 utilizes ultra-efficient emitters to reach a higher luminous efficacy value, allowing us to produce twice as many lumens with only a 50% increase in power draw.

      Dimensions - the A19 bulb utilizes the traditional A19 lamp size, while the A21 bulb is slightly wider and longer. For lamp fixtures with smaller lampshades, you may find that the A21 bulbs "stick out" a bit and may be an issue if such aesthetics are of concern.

      The A21 bulb has a diameter of 2.76 inches (70 mm) and a length of 5.24 inches (133 mm).

      CRI, color temperature and flicker - all of the color rendering, color temperature and flicker-free metrics are identical across both the A21 and A19 bulbs.

The gold standard for Color and Tint

I've been using Waveform's products for a year now and I'm very much happy with their lights so far. It's difficult to find any LED's in stores that have more white color options other than 2700k or 5000k. They often have nothing in between nor have a CRI 95+. Our basement is pretty dark with little natural light shining through, so we needed the extra brightness and we'll often leave it on all day while working at home. These deliver that, and are what I needed to replace the remaining lamps in our basement, and since it only uses 15w that makes it great for reducing costs on our electricity bill long term.

Many praise the flicker free qualities and I can attest to that. Usually when our AC starts up, our older lights would sometimes flash quickly, but with these, you couldn't see it at all. It really shows how much Waveform made effort to making sure these lights are up to quality. The tint is beautiful as always, with a neutral, but slightly rosy tint. It just makes your house feel more comfortable to be in and it really brings out the colors and decor in our house especially the reds, like old incandescent and halogen lights would. I've yet to see any store bought LED that can reproduce light as similar as Waveform's, and once you start placing them in your house, you'll understand how important light quality is.

If there was any criticism, they are unfortunately, a bit directional as someone mentioned. (To be fair, most typical LED bulbs aren't full 360 degrees anyways, unless they are a filament LED bulb) They do best in fixtures that face the light bulb down so as to get more light facing downwards when doing task work, but otherwise it's fine regardless of direction. Waveform does sell LED filament bulbs, but that's at a lower 450 lumens. I'm hopeful they'll release a 800 lumen or even a 1600 lumen version for that some day as those can actually be dimmed as well. Having the ability to dim would be nice, but these ones don't have any flicker to them, so it's something else to consider.

Maybe in the future Waveform will consider making a color temp adjustable LED bulb and expanding it across their other lights. Smart LED bulbs are quickly becoming popular in homes, There's now smart bulbs that have a CRI of 90+ that are becoming available in the market, but many still lack the high CRI that Waveform makes and often the color temperature or tint isn't consistent, which is why I haven't made a huge jump on those quite yet. Having the ability to adjust the color temperature depending on the day is quite the game changer.

Waveform bulbs can be quite expensive, but knowing their excellent customer service and their willingness to do better, It's worth the extra cost knowing how many other manufacturer's can cut corners to save costs, and knowing they may not last as long making you replace the bulbs frequently. Fortunately Waveform stands by their products and they will happily help if there's anything wrong with their light bulbs under their warranty. Would highly recommend.
