- Light rays that have relatively long wavelengths contain less energy, and those with short wavelengths have more energy. Rays on the red end of the visible light spectrum have longer wavelengths and, therefore, less energy. Rays on the blue end of the spectrum have shorter wavelengths and more energy.

Daylight Bulbs
One of the main ways people tend to identify and label light bulbs is equal to their “color temperature.” This doesn’t refer to the actual temperature of a bulb. Instead, it’s referring to the color light output. So, for example, full-spectrum lights that fall in the “warm” part of the category are giving off more yellow light. In contrast, “cool” lights have more of a blue or white color. This means that bulbs that are just labeled “daylight” tend to have more blues in their color makeup, as...
Full Spectrum Light Bulbs
In contrast, full-spectrum bulbs use filtersto copy all of the colors of the white light from the sun. “Full-spectrum” refers to the visible spectrum of light. Different wavelengths of light appear to us as different colors. The visible spectrum ranges from long wavelengths (reds) at one side of the scale to shorter wavelengths (blues) at the other end. Wavelengths of light get refracted differently as they travel through our atmosphere at different angles, making the light appear warmer at t...
One important thing to keep in mind when it comes to analyzing light bulbs is something called the Color Rendering Index. This is a way of measuring how accurately the light renders the colors of the objects it’s bouncing off of when compared to how well natural or “perfect” light would do it. The CRI is not the same For example, many “daylight” bu...
Beyond the big benefits that matter the most, there are a few other ones that are also rather interesting and beneficial. A study from RPI suggests the following points on increased light bulb spectrum: 1. Improving Retail Sales: Obviously, this is going to matter to those in the business more than others. However, it’s certainly a potential benefi...
Light Boxes Some people use light therapy boxes, which are small units with an embedded full spectrum light bulb as a light source. The produce an intense daylight blast of light from LED bulbs, with a spectrum containing blue, yellow and red light. Portability is an advantage compared to a full spectrum bulb, and they are often used by those with ...
Daylight is just one of those things that affects human beings in a deep way. It’s in poetry and stories of all kinds, going back for millennia. Daylight represents our hopes for life and happiness, our ability to understand what’s around us, and our ability to feel safe, calm, and content. Writing down all the quotes about daylight that humans hav...

Mar 14, 2023 · Sunlight is the main source of blue light, but as more of us use laptops, flat-screen televisions, tablets, and smartphones, we increase our exposure to blue light that mimics daylight. Fluorescent lights and some types of LED lightbulbs also emit higher levels of blue light compared to incandescent bulbs.
Oct 11, 2023 · Red light therapy is commonly used for skin rejuvenation, pain relief, and hair growth. Blue light therapy emits wavelengths between 400-500 nm and only targets superficial skin layers, effectively treating acne, improving the skin microbiome, and boosting alertness by influencing circadian rhythms.
