Find the Best Light Bulbs

Find the healthiest light bulbs for your home with the world’s largest database! The desktop experience is recommended.

Learn more about the color quality aspects of lighting:

We just got our hands on a new spectrometer and we’re getting a professional-grade integration sphere.

This will allow us to get more accurate spectral data, including LUMENS! No more of this “800 lumens” nonsense you see on every single light bulb package…

We will be retesting every light we’ve tested so far, and many many more.

A light’s color temperature is essentially a description of how humans perceive the overall hue of a light source. The color of natural sunlight varies throughout the day, however, it hovers around 5700K for most of the day.

Some lights in our database differ greatly from the manufacturer’s stated CCT, we’ve included our measurements so that you know what you’re buying.

As evening and night roll around, low/no blue light sources with warm color temperatures are ideal, think <2200K.

CRI (Color Rendering Index)

CRI is a unit used to represent the ability of a light source to reflect the true colors of objects, compared to a natural light source, like the Sun.

It’s currently the most popular way of determining the color quality of an artificial light source and can be seen on many light bulb packages.

For CRI, a score of over 90 is considered good, however, I prefer to see over 95 for this metric.

A little dirt on CRI: CRI used to comprise only 8 colors. The average of these would be called the “Ra” or the average R-value. The CRI standard has since added 6 more colors, however, one of them, R9 (deep red) is more difficult to get high scores on. So most companies still only use the first 8 to calculate their “CRI score”.

We use an average of all 15 colors in our calculations, so the CRI score may be lower or higher than what is typically advertised for each light.

TM-30 (Rf and Rg)

TM-30 was created in 2015 and is a new alternative to the CRI standard.

While CRI only measures 8 to 15 colors for its average score, TM-30 uses 99 total colors.

The TM-30 gives us three important metrics:

  1. Rf or Fidelity: This is a number of 1 – 100 that measures the reflected light accuracy compared to a standard, similar to CRI.
  2. Rg or Gamut: This number shows how saturated a light source is on average. A number higher than 100 indicates it’s slightly over-saturated, while a number under 100 indicates under-saturation.
  3. Color Vector Graphic: Finally we get the CVG, which gives us a visual representation of color saturation.

If you’re at all concerned about how similar your light is to sunlight, the only current metric to measure this is the ASD unit developed by Bridgelux.

ASD measures how much a light source varies from a blackbody radiation curve of the same color temperature.

comparison of several lights against a 3000k black body curve

As you can see above, even though all the light sources are 3000K, the ASD percentage is higher for lights that are less similar to the black body curve.

The ASD metric should only be used to compare lights of the same color temperature.

If you’d like to read more, Bridgluxe’s ASD whitepaper is quite an informative read.

Almost all lights have an “invisible flicker”, if this bothers you, our database has lots of info to help you choose flicker-free lighting.

The flicker depth shows how much the brightness of a light source varies from its minimum brightness to its maximum brightness.

For example, a light source that varies from 100 lux to 80 lux, would have a flicker depth of 20%.

Generally speaking, we want this to be as low as possible, as sunlight doesn’t flicker at all.

The waveform graph actually shows you the flicker depth plotted on a 24 ms time slot.

waveform graph from an LED

Waveforms can vary dramatically from one light to the next.

It’s possible to associate headaches with certain types of waveforms, so if this is you, you can use this graph to decide which lights might irritate you and which might not.

This graph is based on the IEEE’s PAR1789 flicker standard.

While this standard isn’t perfect, it’s the best we’ve got right now.

This graph essentially takes the flicker frequency, seen in the waveform graph, and plots it against the flicker depth.

The idea here is that the lower the frequency and the higher the depth, the more likely a light source is to cause noticeable biological problems.

flicker risk graph from ieee

The Flicker index is a measurement that takes into account the areas above and under the light’s average output and calculates this as a number.

This gives us a good numerical value for how much time the light source spends away from the median brightness level.

      Hey Jack! Thanks for the suggestion, I’ll try to get my hands on these.

    I’d love to see some higher-lumen bulbs like corn bulbs rated here. I have a 12000lm one I’m happy with but had to give another one away because of its flicker

    1. Derek Antosiek Avatar

      I’ll see what I can do about adding some of those. Are there any brands in particular you had in mind?

    On the Dimmable bulbs (like some of the Phillips), how do they respond when dimmed? Does it depend on the dimmer?

    1. Derek Antosiek Avatar

      In my experience almost all dimmers have the same effect, they increase the waveform depth. However, they don’t seem to change the frequency as much, so higher-frequency dimming lights remain within the “no risk” category, while low-frequency lights generally get much worse.

    Thank you for making this database! It’s so useful after discovering that most LEDs give me daily migraines.

    However, I’m a bit confused on one of the lights. Waveform have helped me, but I mistakenly bought some of their lights thinking they were flicker free (they ended up causing migraines for me). Their customer support confirmed that only some of their A19 lights are considered flicker free.

    Would it be possible for you to re-test the Waveform Lux24? Your data is showing it as no risk, with no flicker index and low flicker depth. However, Waveform themselves say that it has flicker percentage of 29% (https://www.waveformlighting.com/knowledgebase/a19-bulbs/what-is-the-flicker-rate-of-the-lux24-circadian-bulb). Their spec sheets also shows this https://www.waveformlighting.com/photometrics/TR_4002.24.pdf

    Maybe I’m reading it wrong, but I’d greatly appreciate your feedback!

    1. Derek Antosiek Avatar

      Oh wow I see that! I’m not sure how or why I didn’t detect that with my light. I’ll have to double check it when I get my hands on another light.

      Thanks for pointing that out!

    I also confirmed with Waveform Lighting customer support that their Candelabra lights are not flicker free. It looks like all of their Filament style bulbs are not rated flicker free for them.

    “This was their response: Unfortunately, we don’t have the specs available for our candelabra bulbs at this time. We apologize!
    We can confirm that our filament bulbs (including the candelabra) are not flicker-free based on our internal standards (~2%). However, we guarantee these bulbs have a flicker rate lower than traditional incandescent lamps (20-30%).
    On average, the flicker index is 0.08, and flicker frequency is 121 Hz.
    We suggest taking advantage of our 30-day free return policy to test and compare our products. If you find them unsuitable, let us know within 30 days of receiving the items, and we’ll be more than happy to process a return for you.”

    The bulbs that they rate as flicker free usually show this according to their specs:
    Flicker (%): < 1%
    Flicker index: < 0.01
    Flicker frequency: 0 Hz

      Looks like I’ll have to get my hands on some more for a retest. I don’t currently have any on hand so I’ll have to order some more!

      Appreciate you looking into that.
