The light head can be swiveled and rotated by up to 270 degrees, so you can point it at your sweater or your book whilst knitting or reading. Additionally, you can prop the LALAKU LED light on a flat surface and use it as a makeshift table lamp, too. Cool (4600K – 6500K): At the top end of the scale is cool white light, which increases alertness and productivity. That blue light you’ve heard about in your phone/laptop/TV screen also falls into this category. It’s advised not to use cool light in the evening or when you’re anticipating sleep, as it hinders melatonin production and confuses your body into thinking it’s still light outside.
Colour temperature is measured on the Kelvin scale (K), a numerical scale where warm/yellow light is in the lower numbers and white/blue light is in the higher numbers.
The brightness settings on book lights are usually listed as low to high, or by the type of activity they’re best suited to. 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 best book lights offer multiple color and brightness settings. This is so you can customize your lighting to suit your eyesight preferences. The light angle is only 90-degree, illuminates in a narrow beam. So it only lights up the area you positioned and it is dim enough to other passengers. Other than that, you can also adjust the brightness to the dimmest level.
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. Neutral (3100K – 4500K): The middle of the brightness spectrum offers a mix of warm and cool light, and is the most versatile temperature. Color temperature refers to a system using numerical values to measure the color characteristics of a light source on a spectrum ranging from warm to cool colors. The numerical values can be indicated as degrees Kelvin, noted by the symbol K. In layman's saying, color temperature signifies a way of describing a light source's warmth or coolness color features. The lower the color temperature, the yellower the light; the higher the color temperature, the whiter the light. 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. CRI is the acronym for color rendering index, and you can usually see it when browsing some lighting bulbs and fixtures. In general terms, CRI measures a light source's ability to show object colors "realistically" or "naturally" under an artificial white light source compared with sunlight. In other words, the higher the CRI, the more attractive and vibrant your lighting objects will be .
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.
Amber Book Light: As for the amber light, 20 lumens are commonly preferred. The soft and gentle amber light will stimulate your body to produce more melatonin naturally. It is widely used for reading in bed before sleep with the special amber mode. 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!) The best book lights, at a glance: 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.
