Light bulb colors: soft white vs. cool white vs. daylight If you’ve ever walked into a living room that felt kind of like a dentist’s office or had to squint when looking in the mirror in the bathroom, it’s probably because the light bulbs were the wrong color. The difference between a soft warm light and a harsh blue light is massive. And that’s why it’s so important to find the right LED color and temperature. So how can you find the right bulb for your home? Light bulbs generally come in three “colors” (also called temperatures) with an associated amount of kelvins (we’ll get into that a bit later): Soft / warm white (2200K - 2700K) gives a warm and cozy (almost yellowish) hue to the room. It’s best for living rooms and bedrooms. Cool white (3000K - 4100K) is a more standard white color, and it’s most suitable for a kitchen, bathroom, or study room. Daylight (5000K - 6000K) gives off a bright, blueish light that works best for things like reading lamps. It’s usually not a good idea to use these for an entire room. What does yellow, white, or blue mean in a light bulb? We’re saying that bulbs give off a yellow, white, or blue hue. But obviously they don’t turn your room that color. Without getting too technical, here’s what’s happening: the hotter an object, the more types of visible light it gives off, appearing in whole at first as red, then white, and eventually bluish light. The following chart shows the progression of this color change, with the units at the bottom in kelvins. This range goes from oranger “warmer” light at 1,000K, which closely resembles candlelight, to bluer “cooler” light at 12,000K which resembles a clear blue sky. The “cooler” the light (more kelvins), the closer to daylight the human brain thinks it is. This is what makes cooler bulbs perfect for areas where you need to be alert and be able to perceive contrasts, such as a kitchen, while these kinds of lights would make it harder to fall asleep if used in a bedroom. Generally, you’ll want to use “warmer colors” (below 3,500K) for 70% of your lighting, saving the whiter or bluer lights in areas where more detailed work is done. >>> See More High Voltage LED Strip Lights - A Comprehensive Guide at https://glose.com/activity/658c3070d1d607698236fcd0 Light bulb color accuracy The Color Rendering Index (CRI) is another thing you might see shouted out on a bulb label or description. Also known as color accuracy or high chromatic index (HCI), it measures how well the light shows colors. The image below, courtesy of Derun Lights, shows how different an object can look with different CRIs. CRI is scored using a value from 0 to 100, where 100 is the score given to direct overhead sunlight. As you can see from the image above, objects under light bulbs with lower CRI scores appear washed out and can cause colors to blend or become dull. Objects under bulbs with higher CRI scores appear more crisp, and more variations of colors can be seen. A CRI minimum of 80 is required to receive the Energy Star designation, but for areas where more detailed tasks occur, a CRI of 90+ is recommended. The best light bulb lumens for each room It’s not only about the color of your bulbs. You’ll also need a different amount of lumens (which measures brightness) depending on the room. For more details on lumens, you can read our guide to LED lighting. But this chart gives you some general guidelines for how many lumens you’ll want in each room. Generally, the more detailed work you expect to do in an area, the brighter you want the space to be and the higher lumen per square foot value you want. You can get the number of lumens you need from one bulb in one lamp, or you can spread it among many bulbs throughout the room.

How Solar Yard Lights Work If you've ever wondered how solar cells work, then understanding the inner workings of solar yard lights should be of great interest. These innovative lights utilize standard solar cells in a clever and straightforward manner. >>> See more How to Install LED Light Strip for Your Smart Home Set Up? at: https://band.us/band/90424574/post/33 Harnessing the Power of the Sun In a solar yard light, a single solar cell can generate up to 0.45 volts of electricity, with the amount of current depending on the cell size and the intensity of light it receives. To increase voltage and power output, four cells are wired in series. This arrangement allows the yard light to produce a maximum of 1.8 volts and roughly 100 milliamps under bright sunlight. The solar cells are directly connected to a standard AA Nicad battery. To prevent backflow of the battery's current through the solar cell at night, a diode is strategically placed in the circuit. During the day, the battery charges, reaching its maximum capacity, except on shorter winter days or when the sky is heavily overcast. Nightfall and Illumination As night falls and the solar cells cease producing power, a photoresistor takes the stage. The photoresistor triggers the activation of an LED, just like in the automatic streetlights' operation. This setup employs a simple circuit comprising transistors, replacing the relay found in streetlights. The controller board, which receives power from the solar cells and battery, also takes input from the photoresistor. It contains a three-transistor circuit that switches on the LED once the photoresistor detects darkness. >>> See more LED Strip Lights: Enhancing Your Space with Versatile Ceiling Lighting at: https://hub.docker.com/r/bestledlightstripsblls/led-strip-lights-enhancing-your-space-with-versatile-ceiling-lighting Shedding Light on The Illumination Operating on approximately 45 milliamps and producing 1.23 volts (0.055 watts), the LED emits light equivalent to half that of a candle. While this level of brightness may not be sufficient for illumination purposes, it is ideal for marking trails. These lights provide enough visibility to see, albeit insufficient to brightly illuminate the ground. Illuminating the Cost Currently, solar yard lights come with a hefty price tag due to the cost of solar cells, and to some extent, the Nicad battery. Solar cells remain expensive to manufacture as they require silicon crystals and cleanroom conditions. Although the cost has decreased over the years, solar yard lights still range between $10 to $20 per unit. Some pricier models come equipped with a combination of an LED and a small halogen flashlight bulb. While the LED remains on at all times, the light bulb activates for a minute or two when a motion sensor detects movement.
