What Are TruWave Bulbs?

TruWave Technology™ from Sylvania delivers an industry-first approach to indoor lighting. It is available in LED lamps, luminaries, tubes, and downlights.


It is an alternative to natural light for rooms, buildings, or environments where sunlight access is minimal. This makes it an essential product for offices, healthcare settings, retail destinations, classrooms, and homes.


Because TruWave Technology mimics the sunlight spectrum, fewer transitions occur during the day. With less blue light to cause eye strain, color vividness in the surrounding environment becomes more noticeable.


TruWave bulbs achieve this by replicating the wavelengths between 380nm and 770nm without anything missing. That's how superior color quality becomes available.


What Is Natural Lighting?


Life wouldn't exist as it does today without light. Think about how you feel on a sunny day compared to one with overcast skies. The sunlight helps people feel energetic. The warmth and light feel fantastic when you step outside to soak it in.


We use natural light from sunshine as the baseline to determine how items in our environment look. With the inclusion of artificial illumination, we've also become used to compromising our perspectives.


That problem no longer exists with the introduction of TruWave bulbs.


Light vs. Natural Light


When comparing artificial light with a natural alternative, you can see four different outcomes when looking at a specific object. Each one shifts how the item is seen because of the illumination profile.


Here is a brief look at the four categories of how artificial light alters a natural perspective.


Light Shift Issue

How This Light Compares to Natural Light

Hue Shift UpAn object's appearance moves upward on the color wheel when this effect occurs. How far it travels depends on the shift amount from the artificial light source. For example, a red object would appear to be orange in this environment.
Hue Shift Down If this effect is present with artificial light, it causes the color perspective to travel downward. A red object would appear to have additional pink tones to an observer.
Saturation This effect causes colors to appear more vivid. It occurs by having less black or white added to the visual spectrum.
DesaturationColors appear more muted than usual with this outcome. More black and white gets added to the image to create a dull effect.


When natural light is present, the wavelength distribution within the visible spectrum must be comparable to what sunlight offers.


Although incandescent lamps provide a full, continuous spectrum, the warm light it produces creates red overtones in the environment. That creates an effect similar to what you'd see outside at sunrise or sunset.


Some fluorescent lamps claim to provide a full-spectrum experience by blending phosphors with UV stimulation. This effect is only achievable by compromising the color rendering or efficacy.


This makesTruWave Technology a perfect choice. With high-quality LEDs, you receive a balanced solution of high efficiency and improved light quality to reduce the need for compromise.


What Makes LED Lighting Different from Traditional Lighting?

LED lighting uses less energy than incandescent bulbs or compact fluorescent lamps. This is so because the diode light is more efficient than filament technologies.


An LED bulb uses 75% less energy than a comparable incandescent product. At lower power levels, the differences are even more extensive.


LEDs emit almost no forward heat. They provide these additional advantages to consider in all applications, including TruWave bulbs.


  • LEDs are environmentally safe products that don't require special handling or disposal procedures.
  • The lifespan of LED products is up to 50 times greater than some incandescent products.
  • LED lights operate on lower voltage ratings, allowing them to be used in outdoor lighting applications.
  • This technology functions well in hot or cold temperatures.


Sylvania TruWave CRI


Since 2020, Sylvania TruWave LED lamps have offered an alternative to natural light by mimicking the spectrum the sun produces.


This opportunity is available due to the inclusion of TruWave Technology with this LED lamp. Eye strain is naturally reduced by enhancing color contrasts to deliver less intense blue light.


Sylvania TruWave products offer an excellent CRI rating of 90 without experiencing a loss of efficacy.

What Is the Color Rendering Index?

CRI stands for “color rendering index." This rating offers a way to measure the distinctive attributes of a light source.


The CRI chart ranges from 0 to 100.


Warm white lights typically offer a 55 rating on the CRI chart. If you upgrade to a cool white product, the rating rises to about 60 – which is just on the lower edge of the daylight spectrum.


In comparison, Sylvania TruWave bulbs have a rating of 90. That means you receive a brighter room with an accurate color rendering output. You receive a natural look that incandescents and fluorescents are unable to offer.


Product Application Environment: Where to use TruWave Bulbs


Our modern environment is different. With artificial lights available, people have access to illumination at all day hours. That means the evening hours can be as productive as the morning ones, even if the stars are out.


TruWave bulbs change the dynamic by bridging the natural spectrum and artificial illumination gap. That's why this technology offers numerous applications to consider.


Here is an overview of some of the most popular applications that benefit from having TruWave Technology available.


1. Homes

People spend most of their time indoors today, which means less exposure to sunlight occurs.


Lack of sunlight can lead to a variety of outcomes. They might feel tired, have depression-like symptoms, or struggle to focus on specific tasks.


It's not uncommon for people in the northern latitudes to experience those symptoms even while outside during the winter months because the sun has less availability.


Equipping TruWave bulbs in a home ensures that each room provides a supportive environment. It can encourage healthy sleep cycles, more productivity in the home office, or consistent energy throughout the day.


We often think of light as a commodity. With TruWave Technology, it becomes more of an asset. It delivers accurate colors for more visual comfort while increasing how each space is personally enjoyed.


2. Classrooms

Students of all ages show improved cognitive processing speeds, more focus, and better concentration when learning under specific lighting conditions.


TruWave Technology offers the benefits of natural light in classroom environments.


This application can apply to virtually any training venue.


  • Employers can equip TruWave bulbs in training rooms to improve new employee orientation processes, encourage better focus during meetings, or provide supportive training environments.
  • Large-scale structures can replicate the natural light spectrum to create sensations of being outside while people stay inside.
  • Small, windowless spaces become places for testing, studying, or other needs.


Any learning area can benefit when more natural light is available. TruWave bulbs mimic this outcome effectively.


3. Retail Stores

Natural lighting in retail locations provides full-spectrum attributes for shoppers to enjoy. The improved color rendering ensures that accurate decisions are possible, whether someone is looking for new furniture or an updated outfit.


TruWave Technology offers opportunities for ambient, diffuse, and spotlighting applications. Artificial lighting doesn't provide the same benefits.


4. Offices

Constant exposure to artificial light can be detrimental to clients and employees. When harsh blue tones are in the surrounding environment, people can experience a myriad of physical and emotional symptoms.


Even conventional LED products can release intense blue light. Switching to TruWave Technology ensures that the wellness benefits from natural light get replicated inside open or closed office environments.


Installing this option ensures that low flicker, excellent dimming capabilities, and natural light spectrum replication occur to create additional comfort.


5. Public Areas

Natural light in public areas enhances the quality of the space for everyone. It encourages an embrace of the natural flow of the architecture while causing everything to look larger and feel more open.


Hospitality providers, ranging from airports to hotels, have numerous illumination requirements to consider. People need environments where they feel safe and have opportunities to socialize and conduct professional duties.

TruWave Technology plays an essential role in this process by delivering a broad and balanced color spectrum to offer vibrant colors with improved accuracy.


How Can TruWave Bulbs Improve Your Daily Routine?


You can improve natural lighting in your environment in several ways. Some simple steps, like ensuring your furniture doesn't block windows, allow more sunlight to enter the home.


Another option is to paint your interior window frames white. This idea helps amplify how sunlight reflects when coming in contact with the surface.


Keeping the windows clean, using lighter colors, and installing glass doors are additional options to consider.


When you add TruWave bulbs to those ideas, you'll find that shifting your indoor light spectrum is a fast and affordable idea. You'll combine high color rendering preferences with well-being aspects to ensure comfortable illumination follows you throughout the day.
