alt Hacker NewsBedtime Bulb v2 [0], a light bulb that emits less blue light than other lighting, is finally shipping. It took years to get it right, but we figured out how to make a relatively energy efficient bulb that emits infrared and dims smoothly with any dimmer.
My team is also about to ship Atmos [1], a lamp for the bedside that automatically shifts from higher-blue light during the daytime to low blue light at night.

very interesting. Can I control these with home assistant?
I already have a wind down dimming schedule on my entire home. It changes brightness and color temperature gradually over 2 hours. How do these bulbs compare with philips hue?
The blue light “science” is a fallacy. I think N=8 in the original study and the difference in sleep was about 15 mins.
Is it possible for the bulb to gradually lose brightness as the night goes on? The default of a light bulb being as strong as 4am as it is at 1am is certainly simple, but does not make for a good nighttime experience.
Very cool, what’s the temperature range/wavelengths? (good idea to specify it on the product page - otherwise it’s unclear how is it different from other lightbulbs)
