This affects the level of illumination and can impact visibility. Did you know we have an entire section dedicated to Lighting and LED Product Education? How to Choose the Best Seeds for Growing Marijuana? However, as the metal becomes fully heated, it turns into vaporized emissions that create a bright yellow light. They produce light in all directions, which must be redirected downwards to provide the brightest potential illumination. However, because of the omnidirectional issue HPS lights have, the perceived brightness is much less than that of an LED. Score: LED 5, Metal Halide 0 LED floodlights vs High Pressure Sodium floodlights Efficiency High Pressure Sodium floodlights come closer to rivalling LED floodlights than halogen and metal halide. The colour spectrum that the HPS Grow Lights offer is very narrow and limited. Kind LED say you can. Unlike LPS and HPS lights, an LED does not require or emit heat; it is also one-directional, which means light is focused in a single direction without wasting energy or requiring reflection plates to redirect the light itself. Difference between High Pressure Sodium Grow Lights vs LED Grow Lights. They are involved in all aspects of the process from providing a return on investment analysis, implementing retrofits and processing rebates.”, “The difference is stunning, both visually and financially. As a business, there are two things you are most likely interested in: cost savings and quality. LEDs, on the other hand, do not require any warmup time and reach full illumination as soon as they have been turned on. Additionally, the new LED lights provided significantly better color rendering over their high pressure sodium predecessors, Arntzen adds. The principal difference between low and high pressure sodium lights is the operating pressure inside the lamp. Let’s take a look at how high-pressure sodium and LED lights compare when it comes to performance and illumination. In fact, LED bulbs use between 40-75% less electricity than a HPS fixture. Dimmable. Due to the kind of light that these lamps emit, the High Pressure Sodium grow lights are good for plants once they reach the flowering stage of growth. In fact, HPS lights are expected to last up to 24,000 hours if left in an unadulterated state. The package it arrived in, did not have any damage to it. You have entered an incorrect email address!

Table 3 summarizes the energy perfor-mance and economic analysis of the two lighting systems. Super high-quality! In commercial units where a lot of energy is consumed for illumination, production, and even indoor plantation, the use of LED lights carry long term benefits. Chief among the advantages of LEDs is that they have extremely long lives -- they don't have filaments that can quickly burn out -- and they don't contain toxic chemicals like mercury, unlike traditional high-pressure sodium lamps or mercury-vapor lamps. Indoor cultivation has changed the way that growers cultivate anything. It is a better light than high pressure sodium. Power Consumption:LED Grow Lights vs. HPS light 2. Because they are fragile and operate through the use of gas and glass tubing, this makes these lights highly dangerous in environments where other hazardous or explosive materials are being used. This product adopt the high power LED as the light source, using dozens of high power DMX Emitters of 1 watt LED. Metal Halide lamps provide light to the plants by passing an electric current through a mixture of mercury and metal halide gases. There’s practically no aspect (other than price) that High Pressure Sodium lights have performed better in. A number of growers tried these cheap LED grow lights, only come away discouraged by the results. Electrical Startup time is a concept that is practically unknown to those using LED Grow Lights because they light up instantly and hit peak intensity as soon as you switch them on. It must be known that High Pressure Sodium Grow Lights offer a lifetime of about 14,000 to 20,000 hours at the most. When it comes to illuminating large areas, parking lots, or industrial areas, you may find yourself looped into the high-pressure sodium lights vs LED debate. Light-emitting diodes are changing the commercial lighting maintenance landscape forever. Kind LED say you can. In the early days of LED grow lighting, there were marketers out there who espoused the positives of the technology and offered it at an appealing price point.

Compared with the traditional light source, high-pressure sodium lamp and LED have obvious advantages. While this may not sound like much time when the lights remain on for hours, it all adds up. For the most part, LPS lights have become outdated and are not a competing factor when it comes to full illumination. LED. It is a better light than high pressure sodium. This feature also appealed to Presence Saint Francis Hospital, an Evanston, IL-based Level 1 trauma center with 24/7 traffic. As opposed to the HPS lights, Metal Halides are actually the cooler spectrum of light and provide a white tint (on the bluer spectrum). Lifetime basically refers to how long these lights can last for. Because of their low power consumption, LED lights are great alternative lighting solutions for solar-powered systems. When current is passed through these diodes, the positive and the negative charges begin to collide and release photons which result in the generation of light. It's a rebound effect: Cheaper lights lead not to savings in energy consumption, but to more light. – Fruitland Park Library. High-pressure sodium lamp and red and blue LED lamp to apply top light to the plant canopy, both of which can achieve the same output, and the LED only needs to consume 75% of energy. Here’s a closer look at each of them: High Pressure Sodium (HPS) Grow Lights are basically a part of the HID Grow Lights system which consists of lights of two spectrums. Price: High Pressure Sodium lights range between $5-$10. As such, they utilize gas discharge to create light. For the last several decades, most street lighting in the United States has used high-pressure sodium (HPS) technology, which emits orange-yellowish light. Energy Efficiency: Perhaps the most important feature of them all so far – when it comes to High Pressure Sodium grow lights vs LED grow lights, the latter scores a huge win here as it is much more energy efficient – they can provide the same amount of light as an HPS lamp of a higher wattage but will have a lesser electricity consumption. LED Retrofits 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. About 15% of HPS lamps’s heat is also lost due to this. However, when it comes to High Pressure Sodium Grow Lights vs LED Grow Lights, the HPS grow lights lose out quite a bit here as they take a long time to warm up and glow at its full intensity. I have recommended this product to our other 15 libraries in our county. A good quality HPS lamp will give you the same amount of lumens per Watt as an LED. They lose out to LEDs in many cases because their system efficiency is often much lower due to losses associated with omnidirectional light output and the need to redirect it to a desired area. Low and High Pressure Sodium lights are the only light whose source efficiency compares to LEDs (values range between 50 and 160 lumens/watt for LPS and slightly less for HPS). However, when redirected, lighting systems lose roughly 15% of their heat emissions, which equates to 15% of their illumination. HPS Grow Lights. HPS street lighting is being replaced by street lighting technologies that emit “white” light – primarily LED, due to its higher efficiency and longer life. LED fittings are instantly at full output. First, LEDs can produce narrow-spectrum light at wavebands useful for plant growth and development, including blue (450 nm) and red (660 nm). LEDs, which do not have easily damaged internal components, are more likely to survive any of these types of jolts, thus requiring less replacing due to damages. Its parking garage featured yellow high-pressure sodium fixtures that just didn’t pass muster. Power Consumption: LED Grow Lights vs. HPS light 1. Metal Halide (MH) Vs. HPS Grow Light Bulbs. In fact, they have been known to retain 80% of their lumens even at the end of their life. Before we discuss the differences in quality, let’s take a close look at how high-pressure sodium lights vs LED systems can affect your energy and maintenance costs. However, LED grow light panels provide a much greater light coverage due to the possibility of a 180-degree configuration. Actually, yes. On an average these lights take about 15-20 minutes to glow properly. Energy efficiency: Halogen bulbs use a lot of electricity to produce light; which can lead to high energy bills. This magnifies the effect of light pollution - particularly sky glow. High Pressure Sodium lights are considerably brittle when you compare them with LED lights, which are very sturdy and can deal a great deal of physical shock. High-Pressure Sodium Vapor (HPS) lights, on the other hand, works to balance this intense yellow glow. High Pressure Sodium grow lights are useful only during the flowering stage of the plant’s growth cycle and you need to use metal halides during the vegetative growth.
