Bedtime Bulb v2: Preorder
For a limited time, preorder Bedtime Bulb v2 for 40% off of the final retail price with free shipping. Preorders are expected to ship in September 2025 to the US and Canada.

The most-trusted pre-sleep light bulb, significantly enhanced.
Over 40,000 users trusted the original Bedtime Bulb to reduce blue light throughout their evening routines.
Bedtime Bulb v2 introduces key improvements that represent the next wave of healthy lighting:
IRadient: Near infrared light to aid cell repair
Perfect Dimming: Works with virtually all dimmers
Dim-to-Warm: Further reduces blue light with dimming
After years of trial and error, we're excited to share the next generation of sleep lighting with you.

Better Sleep: As simple as changing a light bulb.
Bedtime Bulb v2 is designed to replace the lighting you use in the evening.
Simply replace the light bulbs you use in the last 1-3 hours before bed with Bedtime Bulb v2. Gradually dim Bedtime Bulb v2 down as you prepare for Restful sleep.
Bedtime Bulb v2 emits the most appropriate light for the evening:
- Exceptionally low in sleep-disrupting blue light
- The lowest eye strain-inducing flicker on the market
- High in restorative near-infrared light

LessBlue 2.0
The original Bedtime Bulb introduced LessBlue™, a breakthrough technology that reduced sleep-disrupting blue and green light while preserving natural color.
Version 2 takes it further. As you dim, red light increases and blue fades away naturally.
The result? A gentler light that actively supports melatonin production and your sleep-wake cycle.

IRadient
Bedtime Bulb v2 introduces near infrared light into your sleep space. This subtle wavelength has been shown to boost local melatonin and support natural cellular repair.
Traditional incandescent bulbs offered some of this—but at the cost of efficiency and lifespan. Standard LEDs? They offer none at all.
With IRadient, Bedtime Bulb v2 delivers the healing benefits of infrared in a modern, long-lasting, and energy-efficient form.
FlickerSafe 2.0
You may not see it, but your body feels it.
Flicker, the rapid, invisible pulsing of most lights has been linked to headaches, eye strain, and reduced focus.
The original Bedtime Bulb led the way in reducing it, but version 2 goes further with market-leading flicker mitigation. At full output, flicker modulation is under 2%.
It’s smoother than incandescent. And unlike most “flicker-free” LEDs, which can emit 20% flicker or more, Bedtime Bulb v2 meets the strictest health standards defined by the Institute of Electrical and Electronics Engineers.
Perfect Dimming
While most bulbs struggle to dim cleanly—or demand specialty, expensive hardware—Bedtime Bulb v2 just works.
It glides smoothly from bright to barely there, with virtually any dimmer.
Because light should feel natural, no matter how you adjust it.
Dim-to-Warm
As Bedtime Bulb v2 dims, its color gently shifts—cool white becomes warm amber, like the glow of evening sun or a classic incandescent lamp.
It’s a gradual, almost imperceptible transition. But it changes everything.
The result is light that feels softer, safer, and more natural—perfect for winding down.


Engineer Spotlight: Eric Beam
Eric is the analog electronics engineer behind Bedtime Bulb v2, with 15 years of experience designing the internals of high-quality lighting. Bedtime Bulb v2 is the result of three years spent carefully optimizing every detail.
"After researching the health benefits of infrared, we set out to design a hybrid visible + infrared bulb. We expanded board space to fit higher-quality components than what you'd find in other bulbs. What resulted was a win-win: the best dimming, lowest flicker, and highest quality light possible."

I've tried to find a good nighttime bulb for a few years now, probably tried out 10-15 different bulbs, and this one is the best I've come across.
Really can’t believe how much I love this bulb!
I love this bulb! I’m super picky about lighting, and the quality of light from this bulb is so great - soothing and makes my room look so cozy.
