GEMBARED Calm Reading Light


GembaRed Calm Red LED Clip Book and Reading Light


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!
