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! Note: This is our extra-large clamp light that delivers more brightness which is important if this is your first red reading light. If you want a smaller, more convenient unit then get our Calm Mini in this link.
