Rechargeable Battery:
The Pro II is equipped with built-in rechargeable NiMH batteries designed for convenience and reliability. Once the device is powered on, you’ll immediately see the current battery capacity displayed in clear increments: Full, Medium, Low, or Charge. Throughout use, the battery status icon dynamically reflects the charge level, shifting between full, medium, low, or empty as needed.
When it’s time to recharge, simply connect a USB-C power cable to the Power Input connector. As soon as charging begins, a blue LED indicator beneath the USB-C port will illuminate, providing a clear visual confirmation that the EM2 is recharging. For optimal performance and battery longevity, it’s recommended to allow the unit to charge for a full 12 hours.

Red & Amber Light FAQs
Why Should I Use Red or Amber Lights at Night?
Because your body wasn’t built for blue light after dark.
Red and amber lights mimic the natural spectrum of firelight—free of melatonin-disrupting blue wavelengths. That means your body can wind down naturally, produce the melatonin it needs, and enter deep, restorative sleep. Whether you're reading, relaxing, or getting up to use the bathroom, red and amber lights support your circadian rhythm instead of fighting it.
How Are Red and Amber Lights Different?
Think of amber as calm and cozy, red as pure sleep sanctuary.
- Amber lights are great for evening use, reading, and general wind-down lighting. They’re softer than regular bulbs but still give you plenty of visibility without disrupting sleep.
- Red lights block even more of the blue and green light spectrum—perfect for late-night use, nurseries, or any place you want to create a deeply restful environment.
Where Should I Use These Lights in My Home?
Anywhere you want nighttime light without sacrificing sleep.
We offer solutions for every space:
- Standard Bulb Replacements: Easily swap out overhead lights or bedside lamps in bedrooms, bathrooms, or hallways.
- Reading Lights: Clip-on or handheld red/amber lights make evening reading sleep-safe and eye-friendly.
- Desk & Nightstand Lamps: Ideal for evening work or journaling without flooding your space with harsh overhead light.
- Nightlights for Kids' Rooms & Bathrooms: No more blasting your child with blue light at midnight—our nightlights offer a gentle glow that won’t interrupt their melatonin or sleep cycles.
- Cordless, Motion-Sensing Lights: Place them in hallways, bathrooms, closets, staircases, or RVs—anywhere you need low-impact, automatic light that protects your rest.
Do I Still Need to Wear Blue Light Blocking Glasses If I Use Red or Amber Lights?
Not if you fully light your space with red or amber.
When your entire environment is lit with red or amber lighting, you’ve created a blue-light-free zone. That means you can go without glasses. But if you're around screens or bright white lighting elsewhere (think: restaurants, airports, late-night TV), blue light blocking glasses are still a smart tool.
Are These Safe for Kids and Babies?
Yes—and they’re actually better for them.
Children’s eyes are even more sensitive to blue light than adults’. Red and amber lights create a calm, sleep-friendly environment without stimulating their brains. Our plug-in and motion-sensing nightlights are perfect for bedtime routines, middle-of-the-night feedings, and bathroom trips—without waking them up too much or throwing off their circadian rhythm.
Do These Fit in Regular Light Fixtures?
Yes!
Our red and amber bulbs are designed to screw into standard E26 bulb sockets, so no special equipment or adapters are needed. Just swap them in and enjoy healthier nighttime lighting instantly.
Are These Lights Bright Enough to See?
Absolutely—but without the harsh glare.
These aren’t dim party bulbs—they’re designed for real-life usability. Whether you're reading, walking through the hall, or journaling at your desk, our lights give you the clarity you need without stimulating your brain into “wake-up mode.”

Love!
Love these! Within the first couple of uses I noticed a difference- less eye strain, better sleep, and less brain fog when I use them consistently with screen time.

Nice glasses at a nice price point!
I really like my new cheater chic nighttime readers! I'm in the process of developing the habit of wearing them every evening starting at sunset. :)

I absolutely love these glasses! They helped so much with eye strain
I absolutely love these glasses! I had started noticing that my eyes were feeling really strained while doing computer work, but when I use the glasses I have not been experiencing any eye strain. The color is light enough that having the yellow shade has not been annoying and I even watched a couple movies in them and did not find the color change to be a problem. Also I got lots of compliments about how cute they looked!

Red light table lamp
This is perfect for overnight nursing sessions to keep me and baby in sleep mode. It also does not seem to wake up my husband as much as a normal light has done in the past. Highly recommend!

Lightweight, comfy, and cute!
I love how cute and lightweight these frames are! The lenses are lighter than my other brand of evening blue light blockers, but since I bought these for being with people at night, I'm okay with that!
