Review on Energy-Efficient 2-Pack LED Night Lights with 💡 Auto Dusk-to-Dawn Sensor - Daylight Cool White Glow by Shelley Highter

They can be used as traditional night lights but because of the benefits color options, can even more. Click on "More" to see all the details. LEDs Natural blue LEDs. Other colors are created by adding phosphones, which convert light into color. The result is better color but with fewer lumens. So the further away you are from the blue LED, the less light you get for the same output. Since all of these models are half a watt, the further down the scale you go, the brighter you get. Sorted from least brightest to brightest, it looks something like this: red yellow white green blue Reviews complaining about being bright might be more blue, reviews complaining about being dim might be redder. So why not just use blue. THEORY All but a few life forms depend on the sun. For energy, for heat, for light. But light doesn't just help us see. Plants grow toward sunlight. Newly hatched sea turtles move toward the sunlight, reflecting the moon and waves. In humans, light regulates sleep. Melatonin (an important sleep hormone) is suppressed by morning and afternoon light. And then released when the sun goes down, when the color of the light becomes warm. Warm light, such as from candles, mimics the setting sun's sleep signal and supports our natural rhythm. But what happens when we bring artificial light into our world? Blue light from energy-efficient sources (including LEDs and electronic screens) mimics the early sun's wake-up call. Blue and white light exposure night after night can keep us awake hours beyond our natural sleep time. COLOR Our brain is designed to wake up under the influence of the color of sunlight (around 6000K). Anything in or near this color will disrupt our sleep pattern, whether it's a TV, phone, computer, fluorescent lights, or a small white night light in the bathroom. To get tired and not ruin your sleepiness after bedtime, avoid blue or white light after sunset. If you want to see what it's like, install FLUX on your Mac/PC and use it as the only light source in your home. for some days. Set it to 3000k, get used to it for a few hours and then set it to 6000k right away. That sharp feeling - your brain thinks it's morning. The devices in your home probably do this with you every night, but gradually, so you can't tell for sure. BUYING AID Blue should be avoided at all costs. The only colors you need are red and yellow. Red for the areas between the pillow and the toilet, yellow everywhere. White should only be used in areas that need accurate painting at 2am and are far from the bathroom/bedroom. Yellow and (especially) red aren't that bright, so the light doesn't travel as far, so you need more of it. But how much have you spent on your mattress for a good night's sleep? Even 2-4 per room is still less than $100 for most homes. And half a watt apiece, even 20 of those is only 10 watts, lighting up the whole house for a lot less than a traditional incandescent bulb in a room. This company seems to have several models, this is the newest. Other models complain about glare. This new version has frosted glass to reduce glare. And the pens are non-polarized so you can point them away from you, further reducing glare. First, take one (box) of each color (R+Y) and try both. You are limited by the location of the outlets, but some outlets are above counters, some are behind furniture, and some are ideally located along hallways. Spread the light over the floor, walls and other surfaces for maximum illumination.
