CH Smith Revitalisation Roberts Real Estate, Australian Unity Campbells Place Aged Care, KUNA Alpaca Shop, Collins St Melbourne Lighting Shop Fitout. High Pressure Sodium area lights are most commonly seen on the road and in … LEDs are available in a wide range of colour temperatures, generally from 2700K-6000K (ranging from 'warm white' to 'daylight'). The comparison above between High Pressure Sodium grow lights vs LED grow lights clearly indicates that the LED grow lights have a significant advantage when compared to HPS lights. What’s the Difference Between Sodium Vapor and LED Lights? The comparison between solar powered LED light and conventional light is that the LED lamps have a greater lifespan and electrical efficiency that is many times better than the conventional lighting system. Or is a lumen not a lumen, maybe LEDs are better at throwing light down in a street light application. LED lights have a high color rendering index, and put out a “daylight” color (natural white light) which provides excellent visibility. Let’s explore in depth high pressure sodium vs LED lighting options for your company’s parking lot lighting so that you can make the best decision necessary for your property. I was researching LEDs, and they seem to be less efficient: a 70 watt HPS bulb produces around 6,000 lumens and the 70 watt LED fixtures produce around 4,000. In fact, they're roughly as efficient as LEDs in terms of their light output for each watt of energy used. The LED street lights recommended by the manufacturer representatives would cost more than twice as much to own and operate as the incumbent technology over the life of the streetlights, primarily because the LED street lights required narrower pole spacings to meet the recommended practice for illuminating collector roads, and the cost of the poles per mile dominated the life cycle costs. Over the lifetime of the lamp the LEDs: use less power, have a more ‘white’ light, can be integrated with active and passive sensors, are quiet, and the LED ‘bulbs’ will last years and years. The popularity of that technology is not just due to its energy efficiency. We get many phone calls from business owners needing our assistance with fixing and/or replacing their high pressure sodium light bulbs for parking lot lights and street lights. But the choice is up to you! A LED light bulb generates light by constant movement of electrons. Sodium lamps are very efficient sources of light; but the sheer yellow light they produce restricts them to street lamps and other outdoor uses. We are funded by CNBM Group, a Fortune 500 enterprise and the largest Led Street Light Vs Sodium firm in China. After that, you will SAVE money because LED bulbs are more efficient, using less electricity. Although they are very popular for street lights, they don’t serve many other applications. The arc tube is made of aluminum oxide and the sodium metal is combined with several other elements like Mercury which counter-balances the yellow glow with some white to light blue emissions. HPS fixtures are an improvement over low pressure sodium (LPS) bulbs because of a better color rendering index (color of light appears more natural). LEDs are solid state lights (SSLs) that are difficult to damage with physical shocks. The new lights use less energy, dramatically cutting carbon emissions and saving money. The biggest being that of energy efficiency as the lights really consume very … LED vs High Pressure Sodium. Typically, above 70 CRI. For the last several decades, most street lighting in the United States has used high-pressure sodium (HPS) technology, which emits orange-yellowish light. This product adopt the high power LED as the light source, using dozens of high power DMX Emitters of 1 watt LED. found on commercial properties, schools, and other types of businesses. Hint: LED streetlights win this battle. High Pressure Sodium lights have often been seen as the best grow light available for amateurs and professionals alike, and the key to their popularity is their incredible raw light output. The large color spectrum of LEDs creates a widespread light output for better visibility and safety. HPS street lighting is being replaced by street lighting technologies that emit “white” light – primarily LED, due to its higher efficiency and longer life. Yes, for us the consumer. LED: Lifetime: HPS Lights have good lifespans – around 14,000 hours – though this is significantly less than LEDs. Conventional lighting is a game of yesterday Street lighting technology comparison light technology life time lumens per watt incadescent light 1.000 - 5.000 11 - 15 mercury vapour light 12.000 - 24.000 13 - 48 metal halide light 10.000 - 15.000 60 - 100 high pressure sodium light 12.000 - 24.000 45 - 130 low pressure sodium light 10.000 - 18.000 80 - 180 fluorescent light 10.000 - 20.000 LED fittings are instantly at full output. Okorder.com is a professional Led Street Light Vs Sodium supplier & manufacturer, offers integrated one-stop services including real-time quoting and online cargo tracking. The HPS light fixture was developed by General Electric and made its debut in 1964. HPS vs LED CRI: When comparing high pressure sodium vs LED lighting options, LED wins with its high color rendering index (CRI). HPS vs. Phoenix: HPS to LED Street Lighting Conversion The City of Phoenix currently maintains over 95,000 street lights along more than 4,800 miles of public streets. In fact, LED bulbs use between 40-75% less electricity than a HPS fixture. Like Metal Halides, High Pressure Sodium lights are omnidirectional, which wastes light and makes them less efficient. From what I have read low pressure sodium puts out approx 180 lumens/watt so a 100 street light would be 1800 lumens, a 400 watt bulb would be around 72,000 lumens using that figure. High pressure sodium bulbs ("lamps") are an old standby for lighting that's still used today in spite of so much talk of LED lights. High pressure sodium fixtures are not as energy efficiency as LEDs. In fact, LED bulbs use between 40-75% less electricity than a HPS fixture. LED Chips are mounted on a circuit board, so depending on the configuration, usually 180 degrees. LEDs are typically 40,000 - 60,000 Hours. Even so, HPS fixtures put off more of a yellow hue due to color limitations (compared to newer LED technology). Jul 28, 2016 | Blog, LEDs, Lighting, Parking Lot Lighting. Where LEDs really shine, however, is in their system efficiency (the amount of light that actually reaches the target area after all losses are accounted for). Initially, LEDs will cost more to install, but the energy-savings, low maintenance costs, and lifespan puts them ahead of HPS lights. LED fittings are instantly at full output. Because of this, LED fixtures for parking lot lighting create a safe atmosphere for motorists at night. They lose roughly 15% of their heat emissions which adds to their inefficiency. They also have a longer lifespan (bulb life) with about 10-15 years, which means less maintenance costs, which means less money on replacement bulbs and parts. A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm.. Two varieties of such lamps exist: low pressure and high pressure.Low-pressure sodium lamps are highly efficient electrical light sources, but their yellow light restricts applications to outdoor lighting, such as street lamps, where they are widely used. Led Street Light Vs Sodium Supplier & Manufacturer from China. Typical source efficiency ranges from 80 - 130 lumens/watt. LEDs are very efficient relative to every lighting type on the market. So why are street lights being replaced with LEDs. Although LED and High-Pressure Sodium are both popular options for area lights and outdoor fixtures, let's explore the difference between the two and why you should consider LED lighting. Be the first to get all the latest news and product releases. However, there is exactly one other type of lighting that beats HPS in that category, and that is Light Emitting Diode (LED). The losses associated with Omnidirectional light output rates them below LED. An LED street light is an integrated light that uses light emitting diodes (LED) as its light source.These are considered integrated lights because, in most cases, the luminaire and the fixture are not separate parts.
