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: Color temperatures are measured in degrees of Kelvin (K) on a scale from 1,000 to 10,000. When it comes to book lights “there are two main ranges of temperatures,” explains Sunir Garg, MD, clinical spokesperson for the American Academy of Ophthalmology. “One temperature is around 2,700K. This is similar to what a traditional incandescent bulb emits and is considered ‘warm.' The other range is around 5,000K.This is a typical white light or ‘daylight.'" 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.

The best book lights offer multiple color and brightness settings. This is so you can customize your lighting to suit your eyesight preferences.

While choosing the right book light, you would need to consider certain factors including brightness levels, the comfort of usage, portability, charging options, battery power, style, and cost.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 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. 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. The brightness settings on book lights are usually listed as low to high, or by the type of activity they’re best suited to.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.

LEDs offer a focused light stream which makes them a great choice for any directional light you need, from a reading light to task lighting in the kitchen,” says Legg. “They also have a good longevity, consume less energy than traditional bulbs and are much cooler to the touch.” 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. Lumen and watt measure different things for sure. Watts refers to how much energy the light bulb uses, while lumen indicates the light bulb's brightness or the light output of a light bulb. Watts do not tell you how bright the bulb is, but lumens do. 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.Construction: From metal to plastic, book lights are made of many different materials. Consider durability and whether each book light will work with the type of books that you read. 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. Reading light is generally referred to as a book reading light. Specifically, it’s an electric light that sheds light on your reading material; for people who want to read at night, do some reading in a darker environment, or even do some knitting, a suitable book light may come in handy.
