The term natural lighting is one that is thrown around quite loosely these days in the lighting industry. Very simply put, a lighting source that closely replicates natural sunlight can be considered a natural light source. Sunlight in its pure form has a kelvin temperature of around 5,000 degrees kelvin and a color rendering index of 100. As sunlight comes into contact with the earth's atmosphere and is reflected and refracted by water and dust particles the color temperature actually changes throughout the day ranging anywhere from 5,000 to 6,000 kelvin depending on the time of day and the amount of clouds in the sky. Artificial lighting sources within this range can appropriately be considered a natural lighting lamp as long as the color rendering index is above 90. The color rendering index or CRI is a method for describing the effect of a light source on the color appearance of objects, compared to a reference source of the same color temperature. It serves as a quality distinction between light sources emitting light of the same color. The higher the CRI of lamps with color temperatures of 5,000-6,000 the better objects appear compared to outdoors.
AL&P chose to work with Waveform Lighting because their product line was specifically designed to be the most comparable to natural lighting source on the market. The addition of 5 custom phosphors along with a high output 70 watt full spectrum bulb have combined to create the closest thing to sunlight indoors. Having a color temperature of 5,900 kelvin and a CRI of 96+ there are no other lamps on the marketplace to even compare against.
Unfortunately in today's competitive marketplace some companies have taken to making up their own definitions of what natural lighting is. A lamp with a color temperature of 6,500 kelvin and a CRI of 82-84 is simply not a natural lighting source. Even those touting their 5,000 kelvin bulbs with a CRI of only 82 as a form of natural light are doing the consumer a disservice in our opinion. Because CRI is determined in comparison to a source of the same color temperature a company calling its 4100 kelvin lamps a natural lighting source with a high CRI is unequivocally misleading, because the color of the light is actually several shades more yellow than sunlight and bears little resemblance to it. An incandescent bulb with its color temperature of 2800 kelvin has a CRI of 100 and we all know how unnatural those are and the same can be said for these 4100 kelvin halogen lamps.
Architectural lighting is the intersection of art and technology—principles of design come into play, as do physics, engineering, and the psychological and physiological effects of light. Architectural lighting design focuses on three fundamental aspects of the illumination of buildings or spaces.
1. The first is the aesthetic appeal of a building, an aspect particularly important in the illumination of retail environments.
2. The ergonomic aspect: the measure of how much of a function the lighting plays.
3. The energy efficiency issue to ensure that light is not wasted by over illumination, either by illuminating vacant spaces unnecessarily or by providing more light than needed for the aesthetics or the task.
Cultural factors also need to be considered; for example, bright lights was a mark of wealth through much of Chinese history.
“We often look for fixtures that can do the job of illuminating the space without becoming the headliner, [so that it doesn’t] overwhelm what else is going on in the room,” said Munson. “The lighting has to perform in collaboration with the architecture. They can never be at odds aesthetically—they have to complement each other.” In the end, architectural lighting always works with the architecture, not against it, to create a cohesive spatial experience.
So, to go back to the original question, what is architectural lighting?
Architectural lighting is lighting that enhances, complements, flatters or confirms the experience of a space and/or a structure.

Benefits of Power over Ethernet Networks
• Power and data over single-layer infrastructure
• Safe and cost effective to install
• Based on Ethernet standard
• Future proof and upgradable
• Human centric control with tunable luminaires
• Lights can be used to communicate information to users
• Can be integrated with other systems
• Highly secure
• Creates the possibility for new data
Two factors have allowed for the viability of Power over Ethernet (PoE) as a backbone for smart buildings: improved energy efficiency of systems and devices, and improved PoE standards that can deliver more watts of power to those connected devices. For example, LED lightingis so energy efficient that UPOE products that provide 60W per port can power and control not just one light, but several commercial-grade light fixtures. PoE lighting continues to improve in efficiency, with new standards allowing for up to 100W per port.
The Worlds Most Powerful Glow Stone And Sand Aggregates
Residential or Commercial
Outdoor Kitchen areas
Also great for city park, schools campuses,
business parks and sitting areas
10 minutes of direct sunlight and your bike trails or walking paths will glow for 12 hours or more 20 plus years.
No wiring, no batteries
Firefighters using glow-in-the-dark safety equipment can see a significant reduction in the time it takes to locate a down firefighter. We have partners that specialize in ways to infuse photoluminescence into products and fabrics.
Our training exercises empirically show that photoluminescent gear, as well as strips placed on steps and railings in a darkened stairway, can help save the lives of firefighters and others inside a burning building.
Photoluminescent technology is fail safe, It gives visibility offering orientation without electricity or batteries.
With the photoluminescent gear, the firefighters will be able to reduce the time it takes to find a down firefighter by 45 seconds, or approximately 30 percent.
This is huge in a life or death situation, It’s pretty amazing technology.
Our Photoluminescent glow strip tape can be used to highlight doorways, outline exit doors, identify door exit breaker bars, use as guide path in hallways, in fluorescent fixtures for emergency lighting, and on stairs to identify steps.
It can also be used in automibile rims.
These are self adhesive strips which absorb any visible light and glow in the dark. UV light works best to charge these.
