3. Many Optics Options for Cobra Head Fixrures
LEDs are directional lights. Their light's focussed and with optics lights up the intended location. They have diodes with individual optics and discharge light evenly across surfaces. Optics control the illumination pattern by delivering their designed beam pattern.
Typical road-way distribution patterns include Types 2, 3, 4 and 5. Types 3 and 5 are the most common. Why one works best for you? Let us do a free photometric with one of our many cobra head options.
4. Control Ready and Dimmable
3 pin NEMA
7 pin NEMA
Another great thing about LED Cobra-Head is they can dim down. This means you can turn off or dim each fixture in the absence of motion. This does not affect the life of the LEDs, other than it will extend it. And a dimmed light uses less electricity, saving you even more on your lighting bill.
Think about this. Converting Metal Halide to LED, you might switch from 400 Watts to 120W. At night, if the light dims to 10%, that means the LED is now using 12W. That's a reduction of 388 Watts. (actually the HID lamp consumes 455W with the ballast draw, so you're saving 443W per fixture. That's huge!)
Our LED Cobra Street Lights work with both 3 pin and 7 pin Nema socket enabled controls and smart networks.
5. 4000K and 5000K Color Temperatures
We offer color temperature options in both 4000K and 5000K. 5000K is a perfect replacement for Metal Halide. 4000K is also an option for those states requiring a slightly warmer light. Other color temperatures available upon request.
Both offer a significant improvement over high pressure sodium lights, rated at 2200K. LED fixtures with a CCT of 3000K - 4000K (or a little less) are the best for street lighting in residential areas. The amount of blue light they emit is small.
6. High CRI - 70+
One of the specifications you need to pay attention to is CRI (color rendering index). This is a measurement of the quality of light that the fixture is producing. It is a scale between 0 and 100. Sunlight is 100. A general rule is that you need less quantity of light if you have better quality. LED has high CRI making the quality better than most traditional light sources.
7. L70 Light Maintenance - up to 50,000 hours
Lumen maintenance relates to the lifespan of a light source. LED lights do not burn out like traditional lights. They maintain initial lumens longer. What happens is the light intensity fades gradually, but this usually takes years.
A 70% deterioration in light output is the point at which the human eye notices a decline in the intensity. But, the human eye is only affected when the light intensity of a light source reaches a level of 30%.
Used 12 hours a night, our LED Shoebox fixtures will provide bright, maintenance free lighting for years.
8. Efficacy (Lumens Per Watt)
Luminous efficacy is the true measure of a bulb’s efficiency. It indicates the lumens produced for every watt of electricity consumed. LEDs are more efficient than traditional bulbs with a higher luminous efficacy. High quality LEDs have awesome efficacy ratings. The standard luminous efficacy is upwards of 130 lumens per watt.
To calculate luminous efficacy, divide the number of lumens the lamp generates by the watts of electricity it consumes. LED light fixtures with a higher luminous efficacy are more efficient than those with a lower luminous efficacy.
9. Energy savings and maintenance savings - up to 80%
LED lights offer high-quality light and use fewer watts than traditional HID lighting. What this means is that you will have more intense light but your power bill will decrease. Most of the traditional HID street lights use between 250 and 1000 watts. That does not include the additional 15% energy used for ballast draw.
If we compare this to LEDs, which consume 40 to 300 watts – there is a 40% to 60% reduction in energy. Greater savings when lighting controls are added.
Maintenance costs drops to near zero. Most street lights require a lift to replace or maintain. These jobs are not cheap. Installing a LED fixture that can last 10+ years mean huge maintenance savings.
10. Paybacks can be relatively short with LED Lights
Save Money with LED
LED payback = Hours of Use + Reduced Use of Electricity + Rebates
Rebates may be the least important of the three. High hours of use and high cost of electricity will dwarf the benefits of a rebate.
Everyone likes a rebate. We have created many proposals where payback was under 1 year even without rebates. Contact us and we can help walk you through the math.
11. Reduced Light Pollution
Traditional street light fixtures may illuminate streets and sidewalks at night, however, they are notorious for light pollution. Light pollution is misdirected and excessive outdoor lighting. As countries and cities become more developed, the constant demand for street lighting increases the threat of light pollution.
Light pollution occurs in different ways including light trespass (light spill), sky glow, glare, and light clutter. It affects the environment as carbon dioxide is released into the atmosphere. The International Dark-Sky Association states that each year, about 12 million tons of carbon dioxide are released by invasive night time lighting. The association also estimates that 30% of all street light is wasted.
Light pollution also affects the lifestyle of mammals, birds, amphibians, and insects by causing disorientation and affecting their migration, sleeping, mating, and feeding cycles. LED technology has addressed the light pollution problem by developing light fixtures that focus light only where it is required.
Why Do We Need Cobra Head Street Lights?
If street lights were important 100 years ago, today, their importance cannot be overstated. Pedestrian and driver safety is very important, especially at night. Students coming from a late class, friends going home from a night out, or employees walking from their late night shift feel safer and more confident with sufficient street lighting.
A big number of vehicle collisions occur due to poor visibility at night. Low quality street lighting or the absence of street lights makes it difficult for motorists to see oncoming traffic and obstacles on the street like logs and broken down vehicles that could cause accidents.
Lighting is a key aspect in the landscape design of the streets. The physical appearance of the streets may seem trivial, but it matters as much as other factors. Well-designed street lighting creates a beautiful ambiance and enhances the aesthetics of the residential surroundings. This gives tourists a pleasant experience on their visit to your city and residents develop a sense of pride.
The Problem with Conventional Cobra Head Street Lighting
Street lighting is as important today as it was several years ago. Although traditional street lighting systems have been useful over time, in many instances, they have caused the following problems for cities, municipalities, and residents:
First of all, the energy consumption of traditional street lights is high. Street lighting accounts for up to 40% of the total energy usage in many cities. During cold weather, traditional lamps require more energy to produce sufficient light, and sometimes, they can burst. The adoption of the newer and more efficient LED street lighting greatly reduces energy consumption.
Over lighting is another problem. Traditional sodium lamps, which are commonly used for street lighting, cannot be dimmed easily and thus provide unnecessary bright light. Very bright street lighting not only causes light pollution, it also affects human sleep and health when people are overexposed to it.
Light pollution interferes with astrology and affects the migration of some bird species. In some cities, even when there is low pedestrian and vehicular activity, street lights still operate at high intensity, leading to wasted energy and environmental issues. LED street lights can be controlled and dimmed to provide lighting when required.
Light trespass occurs when street lights produce unwanted light that shines directly onto adjacent residential properties, causing discomfort to residents. Unlike LED street lighting, traditional lighting systems are not capable of producing directional light which is sent only where it is required.
Another problem with street lighting is the maintenance of traditional lighting systems. Due to their short lifespan and poor light quality, they require re-lamping and servicing quite often. A lot of time is wasted on the maintenance process. Money is also spent in purchasing new lamps, fixtures, and on labor.
The inconvenience faced by residents during light maintenance or repairs cannot be ignored. For necessary repairs and maintenance to take place successfully, authorities may have to block portions of some streets for safety purposes. Residents would then have to use alternative routes which could take them longer to get to their destinations.
Also, most cities require that any street lighting problems like broken lights or idle lights be reported using a report form on their websites. It may take a long time for faulty lights to be repaired after residents have reported the problems.
This means that if one street has a couple of faulty lights, it may be dark for a couple of days before any repairs are done. Residents will not feel safe walking or cycling on these streets. The high quality and long lifespan of LED street lights perfectly solves this problem, because they do not require frequent replacements.
Traditional lights like high pressure sodium and low pressure sodium produce a harsh yellow light and have poor color rendering ability. Residents and law enforcement personnel are not able to see objects, vehicles, and people as they normally appear.
Old fashioned street lighting on some streets is unevenly distributed. Lamp posts are placed far apart from each other, creating wide dark patches. In other locations, some critical areas along the street do not have lamp posts. And as cities have developed over the years, the lamp locations have not been re-assessed, so the light remains inadequate.
A serious problem with street lighting is possible stray voltage. Unnoticeable small stray voltages can cause lamp posts to accidentally get electrified. Damaged insulation within the pole can be very dangerous. It could cause electrical shock and kill anyone that comes into contact with the pole.
The Unique Benefits of Cobra Head Street Lighting
Over the years, municipalities have realized that conventional lighting systems are not efficient and do not serve their climate change initiatives. Some of them have started city-wide projects replacing HID lamps with LED street lights because of the following benefits that LEDs offer.
Although the initial cost of LED lights is higher than for other light types, their energy consumption is much lower and the savings quickly make up for the cost; they are more affordable in the long run. LEDs are made in such a way that they provide the maximum amount of lumens using the least amount of energy. Also, the fact that they emit directional light prevents wasted energy, reducing lighting costs.
The Climate Group embarked on a two-year study to examine the use of LED street lights in 12 major cities across the world including London, Sydney, New York, and Kolkata. The company discovered that the use of LED street lighting led to an 85% reduction in energy costs.
The University of California, Davis, and the city of Cambridge, MA, have installed LED street lighting and both locations have realized up to 80% energy savings. The LED street lights installed have sensors that detect activity on the streets. When there’s a vehicle or human traffic, these lights increase their brightness to almost 90%. When there’s no activity on the streets, the light output goes down to 10% minimizing energy wastage.
Many cities around the world have now adopted LED street lights because traditional lighting systems like HPS and MH lamps are inefficient and are big contributors to huge energy bills and greenhouse gas emissions.
LED street lights are a worthwhile investment because they have a longer lifespan than all lights. Their lifespan is 50,000-100,000 hours and they do not experience sharp lumen depreciation. While other light sources burn out, LED lamps provide bright light over a long period.
Human beings notice a decrease in brightness when the light output goes down by 30%. This is why the L70 rating is used. It indicates when light output will degrade to 70%. Unlike other inefficient light systems that last briefly, LED street lights last longer and this reduces the need for constant bulb replacements, saving time and money. During the lifespan of a LED street light, a traditional light may need to be replaced 4 times.
LED street lights are designed to work well during extreme weather conditions. Temperatures as high as 125°C do not affect their efficiency. They also work well in temperatures as low as -22°C.
Cities and municipalities are constantly looking for ways to improve their services while reducing costs. They are now achieving this by adopting LED street lighting. The exceptionally long life of LEDs is the major factor behind reduced maintenance costs. The inefficiency of traditional lights calls for frequent bulb replacements and repairs.
A lot of time is spent reporting the lighting issues, replacing burnt out lamps, and repairing old fashioned fixtures, leave alone the labor costs involved. LED street lights require very little maintenance due to their durability and solid construction. They do not use filaments, ballasts, or fuel and can therefore withstand extreme conditions.
LED street lighting provides high-quality illumination through a high color rendering index (CRI). A high CRI makes objects appear as they would under natural light. For a long time, there was a fallacy that excellent color rendering could only be achieved with high consumption of electricity. LED technology has proven that lights can have a high CRI with low energy usage.
For nighttime lighting, CRI is important for drivers and pedestrians to be able to accurately see objects and people for purposes of identification. With other lighting systems, people would not be able to accurately identify objects in their natural appearance.
Generally, well-lit streets provide increased safety and security. They also deter criminals, since most crime happens in the dark. Drivers are able to drive safely and avoid collisions or hitting objects on the road. Pedestrians are able to see their surroundings and walk safely in case there are obstacles along sidewalks. Quality lighting is also helpful for facial recognition – in case of crime – and identification on CCTV cameras.
Adoption of Smart (Intelligent) LED Cobra Fixture Lighting
Traditional street lighting provides constant illumination, increasing energy consumption and accounting for up to 60% of a municipality’s total lighting electricity expenditure. As electricity prices continue to increase, the energy required by traditional street lighting will remain the same.
Inadequate dimming technology and security concerns in many cities have forced decision makers to enforce new street lighting policies. Some recent policies require all lights to be fully functional throughout the night. Inadequate dimming also causes light pollution and decreases the lamps’ lifespan.
With increasing urbanization, smart LED street lighting is becoming the go-to solution. Smart street lighting works by detecting the movement of pedestrians, cyclists, and cars. When there’s no movement, the lights go dim; when there’s movement, they brighten.
This type of lighting reduces energy wastage, minimizes maintenance costs, and enhances safety. Improved technology enables LED street lights to communicate with each other in such a way that when a camera or sensor detects a passer-by, the neighboring lights are alerted and switched on. The pedestrian or cyclist is then surrounded by a circle of light.
LED Cobra Head Street Lighting Is the Future
In many cities, LED street lighting has replaced traditional street lighting. Decision makers in these cities have realized how high their energy bills have been due to the inefficient lighting used. Some municipalities can no longer afford these high costs.
The detrimental effects of conventional lights on the environment, humans, and animals are a major driving factor in the implementation of safe and efficient lighting. LEDs perform better than the best functioning traditional lights.
Cities and municipalities should adopt LED street lights to not only reduce energy and maintenance costs, but to also enhance the safety and beautification of their streets. The seemingly high initial costs of LEDs may be off-putting, but their short payback period makes them the best lighting option – hands down.
