LED claim to fame is you can get a reasonably white light source for much less energy than a white metal halide or mercury vapor (?). Do you think the HPS can be dethroned? Join us as we compare and contrast metal halide, high-pressure sodium, CFL, plasma and LED grow lights to determine which system works best for you. This article will weigh the pros and cons of light-emitting diode (LED) vs high-pressure sodium (HPS) lighting. Many municipalities are weighing the benefits of both LEDs and high-pressure sodium (HPS) as they consider their street-light options. Link below Ever wonder why street lights are orange? There are just many applications where the up-front cost of switching to all LED would be too expensive, and low pressure sodium (LPS) is extremely efficient, nearly as good as the most efficient commercially available LED street lamps. HPS vs LED Cost and Efficiency: Initially, LED lighting options for parking lot lights and street lights are going to cost more than HPS lighting. By running a 2000 watt load for 1 hour, 2 kilowatt hours of electricity have been consumed. Kind LED say you can. The cost, in this case would be $0.278 for one hour of usage if electricity is at the usage rate of 13.9 cents per kilowatt hour. Select the lamp wattage (lamp lumens) Before LED vs HPS comparison, there was a time when HPS (High-pressure Sodium) lamps were dominating the residential, office, farming and industrial lighting scene. Ceramic metal halide (CMH) is another good option for street lighting. 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. What's that light cost you? But when you factor in the efficiency, maintenance costs, and bulb life of high pressure sodium vs LED, this LED initial cost becomes the only disadvantage as far as we can see. Let’s face it, many LED grow lights are expensive! HPS light costs differ based on the particular fixtures, but are cheap compared to LEDs.

High Pressure Sodium vs LED - What’s The Difference Between High Pressure Sodium and LED Lights. The main benefit of using HPS is that they are the only light source with a similar efficiency to LEDs … I will take a white LED street light over a sodium or mercury vapor lamp any day. LED vs HPS and MH Grow Lights – the Ultimate Comparison. They'd give you lots of light with high efficiency and high CRI. The wider spectral output makes individual objects more discernible from each other, and IMO that's what matters. The lamp works by creating an electric arc through … The biggest being that of energy efficiency as the lights really consume very little electricity – and in the long-run pay off for themselves. I'm talking about driving for over 30 minutes with the entire stretch of road constantly illuminated by LED, it starts getting to you after a while. In fact, they're roughly as efficient as LEDs in terms of their light output for each watt of energy used. In 32 months they have literally paid for themselves in savings even if you do not take into account the money you save in replacement HPS bulbs, installation and down time. Wow, ceramic metal halide are 90-93 CRI? They lose roughly 15% of their heat emissions which adds to their inefficiency. Metal Halide are a good source of high CRI white light. Chapter 1 The Difficulty in Choosing the Right Grow Light Between fluorescent, LEDs, and high-pressure sodium (HPS), the great wide world of grow lights can get confusing. Well LED certainly has better color rendering than sodium. They have a rated life of 24,000 hours. For each: Select the type of lamp (i.e. It is the light itself, even the stretches of concrete road dimly illuminated under the light appear glaring. LED wins this bout. Like Metal Halides, High Pressure Sodium lights are omnidirectional, which wastes light and makes them less efficient. 94 Led vs high pressure sodium led vs high pressure sodium led vs high pressure sodium led vs hps cost comparison you. This results in maximum efficiency, optimal yield, discrete operation, and greatly reduced energy costs. not the rest of the lighting infrastructure, such as the poles and wires. Can you really increase yields and grow quality cannabis with energy-saving lights? Compared to an HPS light, the best LED grow lights might cost 3-10 times as much per unit of light produced. The other issue with LED streetlights is that the high level of optical control has been used by suppliers to put a lot of light at high angles, 50-70 degrees, to improve uniformity and/or to increase pole spacing. One kilowatt hour is equal to running a 1000 watt load for one hour. The cost, in this case would be $0.278 for one hour of usage if electricity is at the usage rate of 13.9 cents per kilowatt hour. Unfortunately, the potential for glare. 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. Turning On and Off. High Pressure Sodium Lights Vs Led Cost. Several other people have commented this as well. I Got tired of looking for the light at the end of the tunnel so i lit that bitch up myself! On a quest for the best lights for growing cannabis? Metal Halide lights have a long warm up time and can take 15-30 minutes to get to full power. One strange thing I have seen on a few roads is LED … No, I know LED street lighting can cause glare because of the intense point-like light sources of the bare emitters, but this is not what I was talking about. 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. Comparison Chart high Pressure Sodium vs. I am not saying high pressure sodium illumination is not hideous, but at night the orange illumination is softer on the eyes than the illumination from a 5000K LED fixture. But I have found that driving on roads illuminated with the new LED streetlamps are a little harsh on my eyes, it feels like there is more glare, and I would even go so far as to say it might make driving conditions more dangerous. LEDs have a light spread of 180 degrees, and so more light is actually directed towards the subject in question. No noticeable strike time is detectable. The primary visual difference between them is that metal halide light is white and the light emitted from a High Pressure Sodium bulb is amber orange. check out the. Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. A brand new, top-of-the-line 600W HPS grow light could cost $200, but I could easily end up paying $800 or more for an equivalent LED grow light. Warehouse lighting example.

Moreover, HPS lights are modular so if one bulb in the set-up fails, it can be changed without replacing the entire system… the go-to choice for cultivating cannabis on a tight budget. I think it has something to do with high pressure and low pressure sodium bulbs having higher out-out per watt, but only in narrow spectra (low pressure sodium being really narrow), or something like that. 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, there is exactly one other type of lighting that beats HPS in that category, and that is Light Emitting Diode (LED). Actually low pressure sodium is the most efficient but it's monochromatic yellow! They are actually designed for street lighting use, and they have a CRI of 90-94 and a CCT of 4200K. I looked at some charts and found that High Pressure Sodium is more efficient than an LED bulb. I got two Sylvania ET-23.5 mogul based 100w ceramic metal halide lamps. I do not remember noticing a glare problem from them while driving, so I think it has to do with more than just color temperature.
