  • Product Overview

    Waveform Lighting has once again pushed the envelope with SUPERWARM™ - a new spectral formulation which features an ultra-warm color temperature rating of 1700K. By going all-in with RedBoost™ phosphor technology, the result is a very soft, warm glow that is reminiscent of candlelight or a deep, fiery-red sunset.

    The 1700K SUPERWARM™ spectrum features very low blue wavelength energy output, making this a perfect bulb for nighttime use where there may be circadian cycle concerns. In fact, based on melanopic sensitivity modelling, this bulb is 60% less impactful on circadian rhythms (M/P ratio of 0.274).

    We also designed this bulb with a respectable 84 CRI rating, which allows for good visual clarity, and makes it a perfect option for bed-time reading and romantic mood lighting.

  • 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 50 watt incandescent bulb, but only consumes 10 watts. You may find that your lamp fixture has a warning regarding the maximum wattage permitted per socket. Use the 10 watt value, and not the 50 watt equivalency value, in confirming compatibility.

Ultra-Low Circadian Impact

 

Our SUPERWARM™ LED bulbs feature a very low color temperature of 1700K. With an M/P ratio of 0.274 that is even lower than candlelight, these bulbs are an excellent option for use during evening hours where light exposure is most likely to affect sleep patterns.

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 SUPERWARM™ LED bulbs extend the same flicker-free technology used in our CENTRIC SERIES™ lamps, and 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 1700K like?

      The 1700K color temperature is a unique color point which exhibits a fiery, red glow. The color is similar to the red glow of a match flame, or an incandescent bulb dimmed down to 5%.

      A typical incandescent bulb at full brightness has a color temperature of 2700K, while a candle flame has a color temperature of 1900K. As its name suggests, SUPERWARM™ LED lamps have an extremely warm color temperature!

      By lowering the color temperature to such a low level, we are able to reduce the blue light content at a spectral level.

    • How is this different from an amber or red LED bulb?

      Bulbs marketed as "amber" and "red" will almost always use a monochromatic LED, which emits light in a very narrow bandwidth that only contains amber or red wavelengths. As a result, all objects will appear amber or red, with no ability to distinguish objects' colors. In fact, most monochromatic LED sources have a CRI rating near 0.

      Our SUPERWARM™ bulbs, on the other hand, utilize a multi-phosphor broad spectrum approach. Although the color may appear to be a deep orange or reddish color, the spectrum still contains a wide range of wavelengths, including yellows, greens and even a tiny amount of cyan and blue wavelengths. As a result, these lamps are able to emit a low-blue light spectrum, without compromising on color accuracy as evidenced by the 83 CRI rating.


    • How much blue light does this bulb emit?

      Our objective in developing the SUPERWARM™ LED spectrum was to limit blue light output as much as possible, while balancing the need for color accuracy. We chose to include a very small amount of blue wavelength energy in order to provide the necessary spectral breadth for color acuity.

      The amount of blue light that this bulb contains is miniscule - far less than traditional "circadian safe" light sources such as incandescent bulbs and even candles. The M/P ratio for this bulb is 0.274, compared to 0.5 and 0.3 for incandescent bulbs and candlelight, respectively.

      For a truly blue-free light source, we would recommend a monochromatic amber or red LED solution (as mentioned above). The downside, of course, is that you will end up losing the ability to distinguish colors, as all objects will take on a pure amber or red shade.


    • How many bulbs should I install in my space?

      For such a low color temperature bulb, an illuminance level of 0.5 footcandle (5 lux) is generally sufficient. As such, one bulb will cover approximately 130 square feet of space. Simply divide the square footage of your space by 130 to get the number of bulbs needed. For example, a 260 square foot area would be calculated as 260 divided by 130, which equals 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 50 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 50 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.
