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!

- 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!
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.

From my son: For small books, it’s might be too big to clip but I don’t really like clipping lights to books. The base is wide enough that it stands up well on a surface as long as the neck/light is balanced. However, when I clip it to my bedframe to read (has a strong clip) I move around a lot so it’s hard to always get the right angle and brightness shining on the page. The level 3 brightness is kinda bright so I usually use level 2 the most. It’s great for a night light to avoid turning on a super bright light to navigate or find things. From mom: I love that my kids can still read before bed and not disrupt their circadian rhythm and this is.great light at an affordable price point!
I use this light on my laptop computer I prefer to use the brightest setting, great light, but the battery only lasts less than 3 hours for me, so I have to charge everyday.
Love it. Perfect for reading in bed at night
I bought this clip light and the smaller one from Gembared. This one is larger than the smaller clip light. It has a base so it can be used on a desk or any flat surface, it's a bit big to clip on a book, but if you need more light, this is great. I would consider it an easy portable red light you can travel with and really use for many different uses. It is quite stout and sturdy, I highly recommend it, along with the small clip light, they are both fantastic, just have slightly different uses, and knowing it is healthy red light is worth it. Gembared and the blog is just such a great place to learn about light and the impact it has on us humans. 5⭐
Soothing light, big sturdy clip.
