The GembaRed Calm is finally the solution for a Red battery-powered book light!
With the Calm Red LED book light is the ultimate reading light for sleep and circadian rhythms!
- Calming red/orange 630nm LED lights.
- Built-in battery powered light and easy recharge with USB connector.
- No Flicker or EMF by using a stable DC battery!
- Silicone goose-neck for easy adjustments.
- Large lighting area.
- Three different brightness settings to customize your experience.
- Large strong clip to attach to a book, side of a desk, or bed headboard.
- Large base to stand itself easily on a desk or bedside table.
The GembaRed Calm is finally the book-light for reading at night! It covers a large area with gentle diffuse red light. There is minimal glare and great contrast with our 630nm LEDs! Perfect for easy and comfortable reading at night to prepare for a good night's sleep.
Most other "Amber" or "Low-Blue" reading lights will still have a trace of blue and a bunch of green in them! Our GembaRed Calm is the first book-light that is only Red! This makes it optimal for avoiding melatonin suppressing blue and green lights!

I love the reading light! At first I thought that it would be hard to read with the red light but you can easily read on the lowest light setting.
I love the light but am shocked at how fast the battery drains. I have to charge it every other day. Read the usage times carefully (I find I need it on the brightest setting to be able to read a book…so only 3 hours!) Please make one with a longer battery life!
We use this night light every single night during bed time with our children. It’s really helped us wind down in a comfortable way. Thanks Gemba!
Love this for reading in bed at night!
While I appreciate the benefits of using this light, especially at night while I read; I find it to be too bulky to clip on a book and it seems to need recharged every other day.
