Feel Better: Well-being all year round
Chromalux® is designed for extended usage as a healthy replacement for ordinary light bulbs. Chromalux® provides your body with the pure full spectrum light it was designed to receive by closely mimicking nature's sunlight. Chromalux® bulbs contain more of the soothing red and violet spectrum with no peaks or valleys in the visible light spectrum, consistent with natural daylight, and unlike many other types of lighting.
See Better: Eye Health, Visual Comfort+Acuity
Chromalux® bulbs are naturally low in flicker, and its signature neodymium glass filters glare and creates better contrast and definition between colors, tones, and textures. Thanks to its inherent chromatic balance and color discriminating qualities, Chromalux® has been a top recommendation for the low vision population since the 1980s - found to increase visual acuity for age-related and other sorts of visual degeneration and sensitivities. Chromalux® works for more than just the low vision population, though. Anyone can feel the soothing difference of living, reading, or working under this unique light. While all Chromalux® bulbs provide soothing vision benefits, it's the light of Chromalux® incandescents in particular worth noting. Our eyes prefer the analog glow of incandescence, the type of nourishing light our sun provides!
Enhanced Environments: Pure+Vivid Colors
Chromalux® is the original neodymium glass light bulb, which works by purifying the visible light spectrum, removing glare and dulling frequencies while strengthening violet, red, blue, and green values. As a result, light is filtered, cutting glare and revealing the most beautiful crisp and vivid colors. Under Chromalux® light, you'll notice colors, textures, and tones become more vibrant and your home more alive.

Will Chromalux® work in ordinary light fixtures?
Yes. Chromalux® is available in most standard bulb shapes and sizes. Just check the max wattage your fixture can accept and choose your bulb accordingly!
Are Chromalux® bulbs dimmable?
Yes, all incandescent and halogen bulbs are dimmable. Always check product descriptions though, as there are some exceptions.
What is the difference between clear and frosted light bulbs?
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.
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 and wattage you need!
Does Chromalux® contain UV?
Chromalux® incandescent contains a minute, negligible amount of UVA, consistent with most incandescent light bulbs. Chromalux® does not contain any UVB - the type of UV that causes skin tanning and damage.
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.
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 magical color enhancing properties!
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 does Chromalux® full spectrum 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 Chromalux® Enhanced™?
Our Enhanced™ collection uses a halogen burner instead of a traditional incandescent filament. An amplified type of incandescence, the resulting light is 18% more luminous and slightly whiter in color temperature than that of our incandescent bulbs. There is no difference in benefits, just appearance of the light. Learn more about the different Chromalux® collections
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). Remember, the higher the wattage, the lower the EMF.
What are the benefits of full spectrum lighting?
Feeling and seeing better! Full spectrum light provides light containing the full visible light spectrum. Plants love full spectrum light, as do people and pets; basically all living creatures need sunlight to thrive, and full spectrum lighting strives to encapsulate that indoors!
Some benefits: improved mood, productivity, and enhanced visual clarity among others.
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.
What is the best or safest light bulb 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.
What is the difference between flood lamps and PAR lamps?
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.
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.
