Many municipalities are weighing the benefits of both LEDs and high-pressure sodium (HPS) as they consider their street-light options. In fact most of the LED fixtures going up right now are. High pressure sodium (HPS) lights have been the heavyweight champion of the lighting world for decades now, ... Aside from the upfront cost of purchasing lights, growers must also consider the cost of electricity. Why bother buying a kind of light if half of what it emits goes the opposite direction of where you want it to go? I looked at some charts and found that High Pressure Sodium is more efficient than an LED bulb. 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 (?). 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. 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. 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. 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. Are LED street lights actually more efficient than High Pressure Sodium? 2.) Lighting Comparison Led Vs High Pressure Sodium Hps And Low Several other people have commented this as well.

Maybe they'd be good for indoor lighting. not the rest of the lighting infrastructure, such as the poles and wires. High Pressure Sodium vs LED - What’s The Difference Between High Pressure Sodium and LED Lights. I discovered something new. It is the light itself, even the stretches of concrete road dimly illuminated under the light appear glaring. 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 High Pressure Sodium What is a High Pressure Sodium Light: High Pressure Sodium (HPS) lights, similar to LPS lights, are a specific type of gas-discharge light (also known as a High Intensity Discharge, HID or arc light). LED Advantages The biggest differences between LED and High-Pressure Sodium lights are color temperature and CRI. For each: Select the type of lamp (i.e. The ones I saw looked about 4500K. I have seen some and the light looked very good, clean and white. LED vs HPS and MH Grow Lights – the Ultimate Comparison. 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. They estimated I will take a white LED street light over a sodium or mercury vapor lamp any day. 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. Price: LED lights are slightly more expensive than High Pressure Sodium lights at $10-$20. The biggest being that of energy efficiency as the lights really consume very little electricity – and in the long-run pay off for themselves. Warehouse lighting example. In the 550m2 area, the cost per kg of cucumber is $1.30 for the high-pressure sodium lamp alone, $1.45 for the sodium lamp and single-row LED lamp, $1.72 for the sodium lamp and 2-row LED, and the profit cost ratio is 2.31, 2.07 and 1.74 respectively.

High-pressure sodium (HPS) lamps would be more cost effective than light-emitting-diode (LED) technology, although the researchers say LEDs could become more economical in the future. It is a better light than high pressure sodium. Indeed, high pressure sodium (HPS) lights are generally unmatched in terms of energy efficiency. The principal difference between low and high pressure sodium lights is the operating pressure inside the lamp. In fact, they're roughly as efficient as LEDs in terms of their light output for each watt of energy used. The High-Pressure Sodium bulb originated in the 1970’s and became ubiquitous in street and warehouse lighting. They'd give you lots of light with high efficiency and high CRI. One kilowatt hour is equal to running a 1000 watt load for one hour. Do you think the HPS can be dethroned? Metal Halide lights have a long warm up time and can take 15-30 minutes to get to full power. LED wins this bout. 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). Since both types of lamp are HID, they are designed to produce generous amounts of light, or lumens. However, there is exactly one other type of lighting that beats HPS in that category, and that is Light Emitting Diode (LED). They offer excellent color rendering (up to 96 CRI), are very efficient (90-110 l/W, about the same as most current LED street lamps), and the advantage is they have a lower initial cost for higher wattage applications than LED. They have a rated life of 24,000 hours. 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. 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. No noticeable strike time is detectable. Metal Halide are a good source of high CRI white light. The reigning champion of grow lights. Our LED products come with a 2 year warranty and approximately 10 year lifespan. Actually low pressure sodium is the most efficient but it's monochromatic yellow! 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. Here are 5 truths about growing bigger yields with LED vs HPS grow lights.
