Warm (2700K – 3000K): Bulbs at the lower end of the scale emit a soft white light that often looks yellow. Warm light isn’t the brightest option but is a good choice when you’re in bed, as it’s the most easy on the eyes. Do you work in a dingy space? You should snag an excellent work light to illuminate your workplace. Up next is yet another clip-on book light that brings a couple more features to the mix. We are, of course, talking about the Glocusent USB Book Light, which can be snagged in five attractive colors. The two arms feature LEDs that provide either 2,700K of warm white light, which is suitable for reading, or 7,000K of cold white light, which is great for more precise working. There are then three brightness levels: spotlight, floodlight, and spot/floodlight combined. Its rechargeable battery lasts up to 16 hours on the spotlight setting, and you can charge it via standard USB.

Instead of revealing the exact brightness of these settings, Glocusent describes them as being bright enough for “general reading,” “brighter reading,” and “precise working.” The brighter the setting, the shorter the battery life, and when we tested this light at home, it took more than three days for the battery to die when using a single light in yellow, general reading mode. This dropped to seven hours when both lights were set to the cool white setting, or precise working mode. This battery is rechargeable but note that it will only charge with the cable that comes in the box. Our review model wouldn’t work with any other USB-C line. Lumen measures the total quantity of visible light emitted by a source per unit of time. Lumens are now a new way of knowing how bright a lamp or a book reading light is. The brightness level of a book light associates closely with the lumen. You might need different book lights in various reading environments depending on your needs. The options that follow cater to a range of lights that offer a short throw, thereby ensuring you don’t disturb your partner’s beauty sleep. At the same time, these lights can aid you in your book-reading and knitting pursuits. The majority of book lights run on rechargeable batteries. Each one’s battery life depends on a number of factors, from the battery’s size, to the brightness setting you choose and how long you read for. Smaller, basic lights will go from full to flat in a few hours, but more advanced lights can run for more than three days of continuous use.Realistically, you’re not going to be reading for three days straight, so even lights with battery life on the lower end of the scale should only need charging once a week. If you’re not reading regularly, they’ll last a lot longer. The main thing to consider when buying a rechargeable book light is what cable you need, and whether it’s compatible with all cables of that type, or just the one it ships with.

Reading a book is a great way to relax before you go to sleep, but unfortunately, an e-book isn’t the best choice, because the blue lightfrom your phone or tablet can make it harder to fall asleep. If you go with the more sleep-friendly option of a physical book but like to keep your room dark to help you wind down at night, a book light is the perfect solution. Plus, if you share your bedwith your partner, the narrow beam of light produced by a book light won’t disturb their sleep. (Look at you, so considerate!)

Clip-On Light: The clip-on book light requires more lumens.Because they generally have bigger sizes and heavier weights. Hence, consumers usually use clip-on book lights as fixed bed reading lamps or a reading light clipping on the bed headboard. For a well-designed clip-on book light, reaching more than 150 lumens is a common practice to light up the entire bedroom, not only for book reading.

Book Light for Kids: Children are commonly perceptive to strong lights when reading, especially using a book reading light due to some reading before sleep. Therefore, the light has to be soft, gentle, and eye-caring for kids. 15 lumens are preferable when choosing a book reading light for kids when reading before bed.
