The package it arrived in, did not have any damage to it. How Do LED Lights Work and Why Are They Better? 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. Lumens refer to the level of brightness your light is capable of. (That is a lot considering roughly 40% of your power bill is spent on lighting alone!) 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. High-pressure sodium (HPS) lights have been frequently used for outdoor lighting LED Provides Effective and Efficient Parking Area Lighting at the NAVFAC Engineering Service Center New lighting technology reduces energy consumption and reduces maintenance while providing effective illumination. Home » High-Pressure Sodium Lights vs. In fact, while you can choose from almost any color range (2700K to 6000K on the color spectrum), HPS is limited to a yellow glow that stays around 2200K. Sodium lights also heat up quickly, even at low voltages. The colour spectrum that the HPS Grow Lights offer is very narrow and limited. One of the main issues with metal halide bulbs is that they tend to lose 50% of their light output half way through their typical lifespan. Many municipalities are weighing the benefits of both LEDs and high-pressure sodium (HPS) as they consider their street-light options. Power Consumption / Dimmability Dialight Energy savings and CO2 emissions reduction Replace 400W conventional light source with 150W LED High Bay for immediate energy savings of 60%, even more when you use dimming and proximity sensors. 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. ... as compared to the yellow and orange high-pressure sodium lights that are typically being replaced. Power Consumption: LED Grow Lights vs. HPS light 1. Metal Halide lights have a long warm up time and can take 15-30 minutes to get to full power. LEDs, on the other hand, were first marketed in the early 1990s for commercial and manufacturing purposes. An electric arc is created in these lights when electricity is passed through it – causing the light to glow. It is a better light than high pressure sodium. The main difference between the low and high pressure sodium lights is the internal operating pressure of the lamp. Additionally, the sodium metal is combined with other elements, such as mercury, to help reduce the yellow tint and give the light a slightly white to light blue hue instead. You have entered an incorrect email address! While this may not sound like much time when the lights remain on for hours, it all adds up.

If the weather is cloudy, the supply would be cut off and if the weather gets too hot, the plants get damaged. Numerous independent field research studies, trying to establish actual energy savings when replacing high-pressure sodium (HPS) luminaires with LED ones in street lighting, had serious deficiencies. LEDs are an instant on and install off. HPS Grow Lights. The scientists think that the method could have other advantages because the cooler LEDs can be placed much closer and along the sides of plants, lighting not only the top, but also the understory. They produce light in all directions, which must be redirected downwards to provide the brightest potential illumination. LEDs, despite … (That means no bumping, vibrations, or other jolts that could damage them.) Therefore, our approach was based on equal photopic or mesopic luminance levels when comparing street lighting installations. They are more efficient and have longer lifespans than High-Pressure Sodium lights. One strange thing I have seen on a few roads is 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. Incandescant, Fluorescent, etc.) Using a passive heat sink would reduce the energy use and, therefore, operating costs of the LED lights. 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. HPS, however, does not. Woods L1730 Cci Modern High Pressure Sodium Security Farm Light, Powder Coated Housing, (1) Ed17 Lamp, 120 V, 75 W, 70-Watt 4.1 out of 5 stars 23 $62.94 $ 62 .

Metal Halide are a good source of high CRI white light. The system is generally comprised of high pressure sodium (HPS) lighting fixtures with only around 750 units of light emitting diode (LED) fixtures installed. Lighting The sneeze guards came 2 to a box and very well packaged. The principal difference between low and high pressure sodium lights is the operating pressure inside the lamp. Comparison Chart HPS vs. HPS vs LED Energy-Savings: High pressure sodium fixtures are not as energy efficiency as LEDs. High pressure sodium (HPS) lights have been the heavyweight champion of the lighting world for decades now, with other lighting systems making only minor challenges to their supremacy.

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. Metal Halides are the other end of the spectrum when it comes to High Intensity Discharge (HID) Grow Lights. This feature also appealed to Presence Saint Francis Hospital, an Evanston, IL-based Level 1 trauma center with 24/7 traffic. The lamp in these grow lights makes use of vaporized sodium metal. 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. 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.
