Everything You Need To Know About LED Lighting

LED lighting is fast becoming the best solution for a wide variety of outdoor lighting applications. The reasons are simple: LEDs are the most energy efficient light on the market by far, they have the longest lifespan (and associated product warranties) by 2-10 times over the nearest competing technology, and they produce a very high quality light with a wide range of characteristics. They are small, steady-state lights which means they don’t present the breaking or recycling issues common with legacy lighting technology. Perhaps the only downside is that they’re not the cheapest light on the market. That said, the price continues to come down and a smart investor will recognize right away that a lifespan that could be an order of magnitude (10 times) longer than a traditional bulb is easily worth the investment. You get what you pay for after all.

One of the most important facilities for high quality outdoor LED light are outdoor parking lots. Parking lots present three major obstacles for owners, real estate organizations and facility managers. First, your parking lot needs to be well illuminated to present a welcoming and safe atmosphere for tenants and customers. The type and specifications of the lighting used in your parking lot typically sets the tone regarding safety and professionalism for the building at large. We refer to this general characteristic as lighting quality. Second, your parking lot lights need to be as energy efficient as possible because they typically operate from dusk to dawn. Third, maximizing luminaire lifespan is important because hiring labor and/or keeping staff on board to routinely change bulbs can become very costly. Primarily for these three reasons it is important to install the best combination of high efficiency, long lifespan, and high quality when choosing a lighting solution. Indoor LED lamp is the 21st century answer to all three problems.

Lighting Quality:

The most noticeable difference between traditional parking lot lights like High Pressure Sodium and modern day LEDs is the color temperature. Notice the incredibly yellow tinge in the “Before” images to the left below. In the same yellow image take a look at the grass. The characteristic green color is almost indistinguishable. Compare that to the same parking lot when it is illuminated by LEDs. The first thing that stands out is all of the green. The trees and grass appear almost exactly like they do during the day. That is a much more welcoming and comforting experience for tenants, customers, and/or employees frequenting the lot.

Using LED Upgrades for Street Lights

Switching to LED lighting leads to significant cost reductions and carbon savings for cities and municipalities. When 12 major cities adopted LED street light, they saw energy savings of 50 to 70 percent.

In New York City, the city decided to replace 250,000 street lights with LED lights. Known as the largest project of this type in the United States, these new lights helped the city save $14 million in maintenance and energy costs between 2015 and 2017.

By 2025, there are expected to be 350 million street lights around the world. Unlike other efficiency projects, LED lights are easy to implement. If the entire United States used LED bulbs for street lights, the country would save $6 billion.

The carbon savings would be similar to removing 8.5 million vehicles from American streets. In Los Angeles, the installation of 140,000 LED street lights in 2013 led to energy savings of 80 percent.

What are Flood Lights?

LED flood light is great lighting fixtures that emit a broad beam of light. As the name suggests, flood lights are used to flood an area with light. It is the best way to provide an enormous amount of non-natural light to an area.

LED floodlights are highly energy efficient and have a higher lumen per watt output than any other conventional lighting system. They are used for many purposes and also allow a range of lighting techniques.

Applications of Flood Lights

The broad beam of flood lights is used in a number of ways across many objects and areas.

Why solar lights could offer a solution to the world's poor

There is an ongoing debate among policy makers, international donors and researchers about how to provide energy access to poor rural areas. For many years, most funding was flowing into large-scale infrastructure projects to expand national electricity grids. However, grid extensions to remote and poor areas are expensive and difficult to maintain. At the same time, concerns about climate change combined with the decline in solar photovoltaic and battery prices have made solar-powered electricity an attractive investment.

Off-grid energy as key to fight poverty?

In particular, pico-solar products, such as small portable solar lights, have gained increased policy attention and international funding. Such products have low up-front costs, need little maintenance, and do not pose the management problems typically associated with national grids or even mini-grids. Solar photovoltaic charged products are hence seen as a possible solution to address both energy poverty and energy sustainability in the near future.Solar lanterns could replace kerosene lighting, which is still used by an estimated 500 million households. The emissions of kerosene lights contribute to global warming and to severe indoor air pollution. Moreover, kerosene lamps typically provide low-quality lighting, at around 10 lumens, while for example a standard LED bulb provides around 500 lumens. On the other hand, solar lanterns only provide minimal access to energy: they can’t power radios, TVs, fridges, or other appliances people may aspire to own as they become wealthier.

Whereas researchers agree that access to grid energy is important for economic growth, there is only scarce empirical evidence of the impact that off-grid energy access has on poverty. That’s why we conducted a policy field experiment in Kenya in collaboration with several policy partners. We analyzed the demand, use and effects of small portable solar lights, combining survey data with sensor data developed by the ETH spin-off Bonsai Systems.

Poor households spend a lot on little energy

At the start of our experiment, almost all 1,400 surveyed households used small kerosene (tin) lanterns with an open flame for lighting. A typical household spent 5–10% of its total cash expenditure on energy, mostly used for kerosene. In comparison, European households spend on average around 4% of their total expenditure on energy, but use more than five times more energy. We found a high demand for solar lanterns among poor rural households, but noticed that they responded very strongly to variations in cost. At the current market price of 9 US dollars, 29% households bought a light; if lights were sold at a subsidized price of 4 dollars, the demand more than doubled (69%).

solar LED light typically replaces one of the households’ kerosene lanterns. As a result, households save around 2% of their overall monthly cash expenditure by spending less on kerosene. We found little evidence that access to better lighting improves children’s performance at school or increases adults’ working time. If only direct economic returns are considered, this would suggest that switching from kerosene to solar lighting might not always be cost-effective. However, this result might change if kerosene prices increase or photovoltaic prices further decrease.
