HPS vs LED CRI: When comparing high pressure sodium vs LED lighting options, LED wins with its high color rendering index (CRI). In fact, they're roughly as efficient as LEDs in terms of their light output for each watt of energy used. HPS street lighting is being replaced by street lighting technologies that emit “white” light – primarily LED, due to its higher efficiency and longer life. High pressure sodium lights work by creating an electric arc through vaporized sodium metal, while additional materials and gases work to start the lamp and control the its color. This product adopt the high power LED as the light source, using dozens of high power DMX Emitters of 1 watt LED. Typical lifespan values for an HPS bulb are around 24,000 hours. We're sure you've been under HPS lights before, and they cast an unsightly yellow color over everything! All Rights Reserved. High-Pressure Sodium: Hot, Hot Heat. 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. (Hint: Yes). Conditions. Power can be done relatively large. Please provide a proper Email Address format. 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. Most values for LED system efficiency fall above 50 lumens/watt. Definitions High pressure sodium bulb. If you're considering a switch or are convinced here of the superiority of LED lights, feel free to contact us for further information. The system is generally comprised of high pressure sodium (HPS) lighting fixtures with only around 750 units of light emitting diode (LED) fixtures installed. The reigning champion of grow lights. One often overlooked benefit of LED over HPS lights is that LEDs turn on instantly. (And Why Greenshine). Higher yields. You can find higher efficacy … What do you like best about LED vs High Sodium Pressure lights? But, there’s a reason … Not convinced? Check the image below. Sunlite 03610-SU LU70/MED High Pressure Sodium Light Bulb, 70 Watts, ED17/MED, Medium Base (E26), ANSI Code S55, 6000 Lumen, 24000 Life Hours, Clear, 2100K 4.4 out of 5 … By continuing, you agree to our Terms & Why bother buying a kind of light if half of what it emits goes the opposite direction of where you want it to go? In fact, LED bulbs use between 40-75% less electricity than a HPS fixture. It is recommended that all activities that can be conducted online be done that way. The High-Pressure Sodium bulb originated in the 1970’s and became ubiquitous in street and warehouse lighting. The difference between led vs hps lumens per watt is greater because there's less "loss" of light. 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. Share it with us today! The two cars side-by-side appear to be the same color, and yet one of them is actually, Concerns about Solar Waste (and When it Comes to Solar Lighting). Prepare yourselves, we're breaking down a big comparison in street lighting today! Many municipalities are weighing the benefits of both LEDs and high-pressure sodium (HPS) as they consider their street-light options. We hope this was a revealing article! A standard "return on investment," if you will, for light. LED wins this bout. High pressure sodium lights, with their familiar orange glow, are quickly being replaced by new, energy efficient blue-white LED (light emitting diode) lighting. High pressure sodium (HPS) lamps start their operating life with a high lumen output that degrades over time, a … This makes them fantastic for security reasons since they can be attached to motion sensors and instantly turn on with the slightest hint of movement. Plus, LEDs have a more accurate color reproduction. Like Metal Halides, High Pressure Sodium lights are omnidirectional, which wastes light and makes them less efficient. Organization. HPS vs. That term is primarily used in discussing efficiency behind lighting--how much light you get per energy invested. More energy goes into the actual light emittance. Due to the low color spectrum on high pressure sodium lights, the light emitted is limited to a warm deep yellow light. Last edited by poiihy; 06-28-2015 at 02:35 PM . LED area lights are top of the line bulbs. LEDs last longer than any light source commercially available on the market. High Pressure Sodium area lights are most commonly seen on the road and in parking lots. Hint: LED streetlights win this battle. HPS lights have been associated with high yields for a long time. Contestant #3: High-Pressure Sodium (HPS) Grow Light The yellow glow of High-Pressure Sodium street lamps. High-Pressure Sodium (HPS) lamps are a type of gas-discharge light that, as the name suggests, operate at a very high internal pressure.They consist of a narrow arc tube within a bulb. Small volume, light, strong wind resistance LED. Sodium, mercury and xenon are the three elements inside the tube, used at different stages of ignition (and for different colored light). LED lighting is programmable and can change according to the amount of concurrent natural light in a space. It's marginal, but we're sure when weighing options that a little more time is better than a little less. LED: Lifetime: HPS Lights have good lifespans – around 14,000 hours – though this is significantly less than LEDs. There's been several power outages and fires across the nati... Biggest Concerns About Solar Lighting: What to Buy and What Not to Buy. However, there is exactly one other type of lighting that beats HPS in that category, and that is Light Emitting Diode (LED). If you have any questions, please call us at, CANOPY, MAILBOX, & BUS STOP SOLAR LIGHTING, What Are the Best Outdoor Solar Lights? DURHAM, NC-- Inspired by the successful Los Angeles street lighting upgrade, where many of the city’s 140,000 high-pressure sodium (HPS) street lights were converted to Cree® LED luminaires, San Luis Obispo, Calif. selected Cree, Inc. (Nasdaq: CREE) to help improve the city’s sustainability efforts.City officials collaborated with Pacific Gas and Electric Company (PG&E) to … LEDs require virtually no maintenance. high pressure sodium system. High Pressure Sodium lights have a high maintenance cost, because they require monitoring and more frequent replacement of both bulbs and parts. Who’s the winner? We'll admit that HPS lights have fantastic longevity, which is oftentimes why they're chosen to light parking lots and wide public areas. Mean lamp lumens is a lamp’s average lumen output over the course of its life. Before Led light come to the market, the high pressure sodium(HPS) lamp is not bad, such as HPS for road lighting has the following advantages and defects: 1. High Pressure Sodium lights have a high maintenance cost, because they require monitoring and more frequent replacement of both bulbs and parts. Here comes the king! 94 For blog updates and free giveaways like us on Facebook and follow us on Twitter! High Pressure Sodium: LED: Winner: Start Up: High Pressure Sodium Lights have long warm-up time, usually around 15-20 minutes. For blog updates and free giveaways like us on, Storage & High-pressure sodium lights produce heat--not something you'd really want when your main concern is just illuminating something. Clearly, LED. HPS light costs differ based on the particular fixtures, but are cheap compared to LEDs. LED Street Lights The high power LED street lights LU1 are designed for the street lighting demand and fully meets the special requirements of street lighting. Indeed, high pressure sodium (HPS) lights are generally unmatched in terms of energy efficiency. Why bother buying a kind of light if half of what it emits goes the opposite direction of where you want it to go? 2.) High-pressure sodium lamps emit a broader spectrum of light than the low-pressure lamps, but they sti The Difficulty in Choosing the Right Grow Light. That completely negates an entire application of security for HPS lights. Here are some main differences between LED streetlights vs HPV streetlights. The main benefit of using HPS is that they are the only light source with a similar efficiency to … The answer to this lies in lumens. The poor color rendering and limited overall light quality means it does not well reflect the human circadian rhythm. High Pressure Sodium lights have excellent lifespan as well (although not as good as LED) which is why they have traditionally been used for outdoor street lighting in municipalities where energy efficiency is at a premium. , '' if you will, for light the heat emitted from the light emitted is limited to a deep!
