About Chromalux®

I'm new to Chromalux®. Anything I should know?

Welcome! Get ready to experience light and your surroundings in a new way. Chromalux® is a unique light bulb intended for year-round, restriction-free usage. That's to say, Chromalux® bulbs are beautiful and healthy upgrades for all your ordinary household light bulbs!

How do I choose between the Chromalux® collections?

We wrote out some of the key differences between the collections here. Let that be your first guide. From there, just find the bulb type you need!

What are the benefits of these types of bulbs?

In a nutshell, our bulbs allow you to see better, feel better, and live in an enhanced environment. These bulbs have a color and contrast enhancing effect that makes life more beautiful! Read more about the benefits here.

Are Chromalux® bulbs dimmable?

Yes, all incandescent and halogen bulbs are dimmable. Always check product descriptions though, as there are some exceptions. 

Will Chromalux® work in ordinary fixtures?

Yes. Chromalux® is available in most standard bulb shapes and sizes. Just check the max wattage your fixture can accept and choose your corresponding Chromalux® bulb accordingly!

Does Chromalux® contain UV?

Chromalux® does not contain any UVB - the type of UV that causes skin tanning and damage. As is the case with all incandescent and halogen light bulbs, they do contain a minute amount of UVA which extends into the visible light spectrum.

Is Chromalux® a colored bulb?

No; Chromalux® is a pure, naturally balanced light source emitting a clean, white light. The lavender appearance of our bulbs is caused by the the element neodymium, which is compounded into our glass and gives Chromalux® many of its special properties!

What is neodymium?

A common earth element, neodymium (pronounced nee-oh-di-mee-um) is compounded into the glass of all Chromalux® light bulbs. Acting as a sort of filter and magnifier, it filters portions of the yellow spectrum - the dulling part of the visual light spectrum that our eyes are most sensitive to - while enhancing reds, blues, and increasing contrasts between colors and tones.


Whereas most light bulbs (whether LED, incandescent, or halogen) produce dull light and can muddle colors as compared to natural daylight, Chromalux® and its special neodymium technology brings meaning to the phrase "seeing life in full color!"

What does Chromalux® light look like?

Like a cloudless sky on a crisp and clear summer day! Chromalux® bulbs "de-haze" environments, making your interiors come to life with enhanced color, contrast and textures, all in a pleasant and soothing way. 

What is the difference between Chromalux® incandescent and normal incandescent bulbs?

Incandescent light bulbs simply use incandescence as their light technology: it's a way of using electricity to make visible light. Chromalux® is our branded technology using neodymium compounded glass that takes incandescent light further - purifying and enhancing the visible spectrum of light produced so colors (particularly reds and blues - the colors our eyes are least sensitive to) are enhanced and vibrant, while contrast is increased. 

A lot of us choose to use incandescents for the wealth of health benefits they offer. But, as great as they are out of the box, incandescent light doesn't replicate all colors purely - and in many cases, fades or yellows them - very much unlike how we see things under natural daylight! 

By passing visible light through our special glass, the colors are reestablished and enhanced, while still keeping that lovely warm and cozy incandescent glow we love! 

What is the difference between Chromalux® incandescent and Chromalux® enhanced™?

Our Enhanced™ collection uses a halogen burner instead of a traditional incandescent filament. An enhanced type of incandescence, the resulting light is 18% more luminous and slightly whiter in color temperature than that of our incandescent bulbs. There's no difference in benefits, just appearance of the light.

Which Chromalux® collection do you recommend for daytime usage? How about at night?

While all Chromalux® light bulbs could be used at any time (due to an increased soothing red spectrum), we find the incandescent collection to be perfect for night time usage, and the enhanced collection for daytime usage.  

What voltage do your bulbs work on?

110 - 120V only at this time. Sorry, but our bulbs aren't rated for use at 240V or other voltages. 

Health + Lighting FAQ

I'm concerned about EMF. Which bulb is safest for my home?

Incandescence is the purest form of artificial light. If EMF is a concern for you, we highly recommend Chromalux® incandescent light bulbs, or Chromalux® Enhanced™ light bulbs (for slightly whiter light perfect for daytime usage). Remember, the higher the wattage, the lower the EMF.

Do full spectrum lights provide Vitamin D?

UVB is necessary for the production of Vitamin D, and only very specified lighting units can provide the light output necessary for Vit.D production in humans. For birds and reptiles, however, this can be achieved through full spectrum fluorescent lighting, usually containing 10% UVB. Chromalux® bulbs do not contain UVB light, which is necessary for the production of Vitamin D. Apart from supplementation, we always recommend some quality time under the sun!

What is the best/safest light for eyes?

Chromalux® full spectrum incandescent light!Chromalux® uses neodymium glass to filter dull and harsh light, while creating incredible contrast between colors and textures. Not only will you see better, your eyes will feel less fatigued! For these reasons, Chromalux® has been a top recommendation for low vision population since the 1980s, and has been proven to increase visual acuity.

Full Spectrum Lighting FAQ

What is full spectrum lighting?

Full spectrum light closely simulates natural outdoor lighting and has a color rendering index (CRI) over 91. It contains the full visible light spectrum.  Learn more about full spectrum lighting here.

Are full spectrum bulbs similar to light therapy boxes? Will they benefit someone suffering from SAD?

This is a great question! While full spectrum light bulbs definitely help those suffering from SAD, they are not considered a standalone treatment for seasonal depression. Light therapy boxes provide a much stronger intensity of light and can be used only for about 30 minutes a day, while Chromalux® full spectrum lighting can be used without restrictions (like a normal light bulb). We actually answered this question in more detail. Read the differences between full spectrum light and light therapy.

Are full spectrum bulbs the same as daylight bulbs?

No, this is a common misconception. Full spectrum light bulbs have enhanced color rendering properties and a balanced visible light spectrum, similar to sunlight. Daylight bulbs do not necessarily mean full spectrum, but instead refer to light bulbs with a color temperature between 5000 and 6500K, the color temperature range of daylight at noon.

General Lighting FAQ

What is the difference between clear and frosted glass?

A clear glass bulb will usually be a few lumens brighter than its frosted counterpart of the same wattage. A good rule of thumb: think frosted glass for general lighting and clear glass for more striking, ambient lighting. If you have eye sensitivities, we recommend frosted glass. Glass type, whether clear or frosted, does not affect the color temperature or appearance of the light.

How do I know which size/type flood bulb I need?

Luckily, light bulb shapes are pretty universal. If you currently use an R30 or BR30 type bulb, then you just need the Chromalux® version R30. The type is usually stamped on the neck of the bulb near the socket. Otherwise, general guidelines are to use R20 bulbs for 3'' diameter cans, R30 for 4-5'' cans, and R40 for 6" cans. Remember to always check the max-wattage rating of your fixture (also printed somewhere within the can/fixture).

What is the difference between flood light bulbs and PAR light bulbs?

While both are perfect for use in either recessed can or track lighting, the light beam of flood type light bulbs (R style light bulbs) have a less defined edge than a comparable PAR light bulb. Flood bulbs are great for general illumination and covering large areas with light, while PAR bulbs are more like spot lights, with a defined and focused beam of light.

What is CRI? Lumens?
