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.

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!

This red light is exactly what I was looking for, for night time reading. Also of note, I had a question/concern and Andrew got right back to me (as in seconds later) to remedy the situation; so A+ for customer service and integrity, too. Speaking of which, the GembaRed Groove was my first purchase. It’s been a few months and that has benefited my health and appearance in very positive, observable ways. Excellent company, excellent products, will be coming back for more!
Own three different GembaRed products and love them all! The reading light is lightweight and will never use anything else to read books at night. Highly recommend!!
I absolutely LOVE this light! It doesn't wake me up when I turn it on in the middle of the night, like regular night lights had been doing in the past. I have no problem going right back to sleep again when using this light!
