Do High Pressure Sodium Lights Use A Lot Of Electricity?

Compared to high-pressure sodium lamps, LED parking lot lighting provides a number of advantages. Let’s take a look at why LEDs are outperforming HPS fixtures.

HPS vs LED Cost and Efficiency:

LED lighting for parking lot lights and street lights will initially be more expensive than HPS lighting. When you compare the efficiency, maintenance costs, and bulb life of high pressure sodium vs LED, the initial cost of the LED becomes the only drawback. After that, because LED lamps are more efficient and use less electricity, you will SAVE money. They also have a longer bulb life (about 10-15 years), which means lower maintenance expenses and less money spent on new bulbs and parts.

Who is the victor? LEDs are more expensive to install at first, but their energy savings, minimal maintenance costs, and long lifespan put them ahead of HPS lights.

HPS vs LED CRI:

When comparing high-pressure sodium vs. LED lighting, LED comes out on top due to its superior color rendering index (CRI). As previously stated, HPS lighting emits a somewhat yellowish tint as opposed to the true white brilliance of LED lights. LEDs’ wide color spectrum produces a broad light output that improves visibility and safety.

Is it expensive to run high-pressure sodium lights?

Low and high pressure sodium lights are both inexpensive to acquire and to maintain. Nonetheless, although having a longer lifespan than most competitors, LPS and HPS bulbs fall short of LEDs.

What is the electricity consumption of sodium lights?

When tested for photopic lighting conditions, high pressure sodium lights are quite efficient, averaging around 100 lumens per watt. The higher-powered 600 Watt models offer efficacy of up to 150 lumens per watt.

Is a high-pressure sodium lamp more efficient than a light-emitting diode (LED)?

LED area lights are the most advanced bulbs available. High-Pressure Sodium lamps are less efficient and have shorter lifespans.

  • Color Temperature: A wide range of color temperatures are available, resulting in better lighting alternatives, including cooler lights than their High Pressure Sodium counterparts.
  • CRI: A higher CRI means better nighttime color vision.
  • On/Off: Instantly responds to on/off input without any delays and can emit a steady, non-flickering light for the duration of their lifespan.
  • Bulb Failure: Instead of flickering or turning on/off randomly, LED lights gradually decrease over time.
  • 25,000 to 200,000 hours of life expectancy.
  • Bulb Angle: A 180-degree bulb angle is used to maximize light efficiency while also allowing for targeted lighting over certain areas.
  • Efficacy: These lights have the highest efficacy on the market, averaging around 50 lumens per watt.
  • LED lights are slightly more expensive ($10-$20) than High Pressure Sodium lighting.

How much does a high-pressure sodium lamp cost to operate?

You’ll use 12.496 KWH per day if you run this equipment for 16 hours a day (the benchmark for the vegging stage). With our pricing of $.12/KWH, that works out to around $1.49 each day, or $44.98 per month.

Are sodium bulbs cost-effective?

In comparison to sodium and halogen lamps, LEDs have a number of advantages. Here are three examples:

LED lights come in a broad variety of colors, which is why so many people use them on Christmas trees. Halogen lights emit a brilliant white light with no fluctuation. Sodium lights exclusively emit yellow light, as previously indicated.

Heat: Unlike halogens, LEDs do not emit heat or burn, and hence do not considerably elevate the room temperature. Even at low voltages, sodium lights heat up quickly. This means that utilizing LEDs is safer, with a lower risk of an unintentional fire.

Halogen lamps need a lot of electricity to create light, which might result in high energy costs. Sodium lights are likewise energy-efficient, but because of the bright light they create, they’re best used as floodlights on the outside of your home or workplace. LEDs, on the other hand, are ideal for a variety of applications and consume a fraction of the energy used by halogen lights.

LEDs with a long life span can last up to 60,000 hours. While halogen and sodium lights have a long life span, LEDs far outlast them in terms of durability. You may run through 20 halogen light bulbs in the time it takes an LED light to burn out.

Is it possible to use an LED to replace a high-pressure sodium bulb?

LED lights made from corn cobs are a fantastic invention. You won’t be able to eat them, but you will be able to light them! They’re a fantastic substitute for older technologies like metal halide and mercury vapor.

Why Are They Called Corn Cob lights?

Increased wattage Corn lights are LED replacement bulbs named for the rows of LED chips on the lamp, which resemble the rows of cob on an ear of corn!

One of the most efficient ways to replace metal halide, mercury vapor, and high-pressure sodium HID bulbs is using LED corn cob lights.

Direct Wire (ballast bypass) and Ballast Driven LED corn cob lamps are the two most common varieties (plug-and-play). We’ll talk about ballast bypass lamps in today’s blog and why you should consider converting from metal halide to LED corn cob lights.

Direct Wire / Ballast Bypass

LED corn cob lights that are operated directly on line voltage are known as direct wire or ballast bypass LED corn cob lights. Over the years, we’ve discovered that the majority of our clients select Direct Wire (ballast bypass) bulbs to replace their metal halide lamps. The concept of removing the transformer (ballast) and connecting line voltage directly to the medium home base (E26) or mogul base (EX39/E39) socket appeals to the majority of people. This will save you money on energy and maintenance by eliminating the ballast’s power consumption and the need to replace it in the future.

Auto Voltage Sensing

The majority of corn cob LED lights on the market use auto voltage detecting technology. They can work with a voltage range of 120 to 277V. Any of the “120V-277V” rated bulbs will operate whether your circuit’s operating voltage is 120V, 208V, 220-240V, or 277V. Corn cob lights are available in a variety of brightness outputs, with replacement wattages ranging from 12 to 200 watts. These corn cobs can be used to replace metal halides ranging from 50 to 1000 watts.

Color Choices

LED corn cobs offer a wide range of color options. Most brands, such as Keystone Lighting Technologies, Philips, Arva, and Halco, have color ranges that start at 3000K and go up to 5000K. The warmer 3000K light is ideal for simulating 3000K metal halide lamps, such as the Philips MHC100/U/M/3K, as well as ALL high-pressure sodium lights. 5000K is a significantly brighter and cleaner appearing option for your corn cob LED light in parking lots, warehouse illumination, or security lighting.

PROS

  • Fantastic Return On Investment – Our customers typically receive a return on investment (ROI) in as little as 6 months. This is usually determined by your electricity tariff as well as the cost of the lighting.
  • Lifespan – A typical corn cob LED light has a lifespan of 50,000 hours, which is about double that of most metal halide lamps, and the lumen depreciation is far lower. These lamps will keep 80% of their original light output after 50,000 hours. At the end of their lives, Metal Halide lumens often depreciate by 50-60%.
  • Energy Savings You can usually halve, if not more, your energy use.

CONS

  • Size Matters – One of the most common complaints we hear from customers is that the LED replacement corn cob light is too big for their fixture. The reason for this is that to achieve a brightness of 10,000 lumens or more, you need a large amount of surface area to place the LED chips on. As a result, some LED replacements are larger than metal halide replacements. Measure your space and make sure the corn cob will fit.
  • Heat kills LEDs – When an LED is used in a fully enclosed fixture, it runs the danger of losing some of its life. Heat build-up might cause the LED corn cob to die prematurely. This is why we always recommend going with a higher-tier manufacturer. Low-cost manufacturers utilize subpar components that may fail, and who knows whether they will still be available if you need to use your warranty.
  • Surges – Corn cob LED lights are commonly utilized in industrial and commercial settings where line voltage surges are possible. Your LED investment could be ruined by lightning strikes or voltage anomalies. Surge suppressors of 5KV or 8KV are integrated into the base of most LED corn cobs. When shopping, make sure to look for surge suppression and keep in mind that you can always add a surge suppressor to your line to help protect your investment.

What’s the difference between a sodium lamp and an LED lamp?

  • What Is the Difference Between Sodium Vapor Lights and LED Lights?
  • Sodium lamps are omnidirectional, emitting light in all directions, whereas led bulbs emit light in only 180 degrees. As a result, Statement 1 is true.
  • The two technologies are completely distinct ways of generating light.
  • LEDs have a lifespan of over 100,000 hours, which is more than four times that of sodium lamps. As a result, LEDs have a longer life expectancy than Sodium. As a result, Statement 2 is false.
  • Metals are vaporized into inert gas within the glass case of sodium vapor bulbs, whereas LEDs are a solid-state technology.
  • Both technologies are extremely productive.
  • The distinction is that in the 1970s, sodium vapor lamps were the most efficient technology, whereas LEDs are today’s equivalent.

What are the advantages of using sodium lamps as streetlights?

Most people have heard of sodium, and those who haven’t are generally aware of its use, even if they are unaware of its importance.

The most obvious example is in street lighting. Because of its high efficiency and the fact that the light they generate penetrates mist and fog particularly well, sodium-vapour lamps are ideal for nighttime illumination. The sodium vapour in the bulb becomes excited as it warms up, creating a distinctive yellow light with a wavelength of 589 nm. LED street lighting, on the other hand, is becoming more popular as a result of the lamps’ long lifespans. It may not be long before sodium-vapor street lighting’s typical warm yellow glow is no longer seen.

You are what you eat

Salt (NaCl) is essential for life, despite recent negative publicity (high sodium intake raises blood pressure). Currently, you have roughly 100 g in your body. Every day, about 3 g is lost through urine and sweat, which is why it’s such an important part of our diet. Sodium functions in tandem with potassium in the body. Ions migrate in and out of nerve axons, causing electrical pulses to pass across the nervous system in waves.

The chemical sector relies heavily on salt. Fortunately, there’s plenty of it: sodium makes up 2.3 percent of the Earth’s crust, making it the sixth most plentiful element. The majority is still mined as halite (rock salt) or extracted as brine (see The lion, the wich, and the waller, p26), but saltwater, which has roughly 35 g of salt per litre on average, is producing an increasing amount. The huge evaporation ponds at Dampier, on Australia’s northwest coast, produce 5 million tonnes of salt every year. This is merely a small percentage of the world’s annual production, which surpasses 250 million tonnes. Sixty percent of this goes toward the production of chlorine and sodium hydroxide, both of which are used in industry.

In certain underdeveloped countries, salt is a godsend since it saves lives. Millions of babies and children die each year from diarrhoea and dehydration, but a drink of glucose and salt can assist, and Unicef provides millions of sachets to make up such solutions. Each one contains 20 grams of glucose, 2 grams of salt, 3 grams of sodium citrate, and 1.5 grams of potassium chloride, all of which must be dissolved in one litre of boiling water.

Any old ion

Another important sodium compound is sodium carbonate, popularly known as soda, when the anion is changed from chloride to carbonate. It’s mined or industrially produced, and it’s used in glassmaking, water treatment, and carbonated beverages to boost carbon dioxide solubility.

So, what about pure metal? It is very reactive and does not occur naturally, but it may be made using Humphry Davy’s electrolysis process, which he invented in 1807. He used moist sodium hydroxide, but nowadays it’s made in a Downs cell from molten sodium chloride combined with calcium and barium chlorides.

Some nuclear reactors employ liquid sodium metal as a heat exchange coolant. The metal is also used in the production of numerous compounds as well as the extraction of other metals such as beryllium, thorium, titanium, and zirconium when heated with their halide salts. It is used to synthesize a variety of compounds, including sodium borohydride (NaBH4), which is used to bleach paper pulp, sodium azide (NaN3), which is used in automobile airbags, sodamide (NaNH2), which is used in dye production, and sodium methoxide (NaOCH3), which is used to make biodiesel from plant oils.

Finally, dissolving sodium in liquid ammonia produces an electride, an uncommon coordination molecule with a single electron as an anion. As the amount of sodium is increased, the result is a deep blue solution that progressively turns metallic in appearance. Sodium is an extremely versatile metal.

How much power does a grow tent consume?

What Is the Power Consumption of a Cannabis Grow Room? Indoor commercial cannabis production (also known as a cannabis grow room) can take 2,000 to 3,000 kilowatt hours (kWh) of electricity per pound of produce, according to the Northwest Power and Conservation Council (NPCC).

What is the power consumption of a 1000w HPS?

In today’s hyper-competitive environment, every grower’s challenge is to maximize profit and change their tactics to stay competitive or gain an advantage.

The optimal approach to replace the sun is one of the most important profit decisions for indoor growers. Cannabis thrives in bright light. As a result, it was discovered that high-pressure sodium (HPS) lamps were capable of producing this level of intensity. HPS technology, on the other hand, necessitates a lot of electricity, and more than half of it is wasted as heat in the grow chamber.

HPS lights are still competitive in some circumstances today, although LEDs are gradually replacing older technology for a variety of reasons. The entire cost of your lighting system will be determined by the operational voltage and current draw, wattage (the amount of power consumed by the lights), heat created, and the level of automation used.

Voltage

Because voltages can be complicated, it’s best to consult an electrician. The voltage you choose has a significant impact on your initial construction costs.

In general, the smaller the current draw, the greater the voltage (fewer amps). This also makes electrical wiring easier to install while keeping the power company happy. The amperage limits the wiring and circuit breakers. As your business grows, so will its current needs.

However, once a facility’s circuits are full, the number of grow lights it can install is limited. As a result, choose wisely.

Here’s an illustration: Let’s imagine you wish to use a 1,000-watt high-pressure sodium (HPS) lamp. This grow light has the highest power consumption and frequently has a 115 percent boost mode, which takes even more amperage. The system must be designed to manage the maximum current consumption, even if the actual alternating current (AC) voltage is 10% lower than the nominal value.

If the nominal AC voltage is 120 volts, it can draw up to 11.5 amps, which implies only one of these lights can be connected to the circuit breaker, as shown in the table above. The lights begin to draw less current as the AC voltage is increased.

When the voltage is increased to 480, an HPS grow light draws 2.7 amps, which means seven lights may be connected to a breaker per-light and yet consume the same amount of electricity and provide the same amount of light.

Wattage/Current

The wattage of grow lights determines how much energy they consume and how much it costs to run them.

Running a 1,000-watt HPS light for 12 hours a day, with around 1,050 watts of actual power use, will use 4,600 kilowatt-hours (kWh) each year. Lower-powered LED bars put near to the canopy can achieve the same light intensity, saving more than 2,000 kWh over the same time period.

There’s also a significant variation in the amount of heat generated by HPS versus LED lights. This is significant since heat will very certainly need to be removed via air conditioning, which is an additional cost to consider.

Heat is measured in British Thermal Units (BTUs) in North America, with 1 watt equaling 3.41 BTUs per hour.

With the exception of the less than 1% of the energy that becomes useful chemical energy (biomass in your plants) in photosynthesis, all electrical energy obtained from the mains in an indoor growing space eventually converts into heat in the room. The remaining is converted to heat, raising the room’s temperature.

When the input wattage is converted to BTUs, a grow lamp that produces 1,080 watts produces 3,682 BTU/h of heat.

This can be beneficial in a chilly environment, but most facilities will need to remove some of the heat.

With lower-power LEDs, the concept is the same, but the numbers differ slightly. Because the downward infrared emission from LEDs is substantially lower, the lights can be placed closer to the plant canopy, allowing more photons to reach the canopy. Cultivators produce the same products in the end, but they use a lot less power from the grid and produce a lot less heat.

Air Conditioning

Another significant cost that must be carefully handled to keep costs low while safeguarding plants is air conditioning. The quantity of cooling required is frequently given in tons. 12,000 BTU/h is one ton of cooling. That’ll power three HPS lights or approximately six LED lights.

In order to predict air conditioning expenditures, cooling efficiency is required. The seasonal energy efficiency ratio is the best indicator of this (SEER). Inquire about your building’s SEER with a heating, air conditioning, or insulation professional. It can also be determined by multiplying the heat output by the air conditioning’s electrical power.

The building’s SEER would be 19 BTU/watt-hour if the grow lights produced 1,900 BTU/h and the air conditioner consumed 100 watts.

So, how can this data be used to determine air conditioning requirements? Consider the following scenario: you have a well-insulated room with 10 HPS grow lights functioning 12 hours a day, 365 days a year, a warm environment, and a SEER of 15. This system would generate 36,820 BTU/h of heat. We obtain 2,455 watts if we split this by the SEER rating of 15. The air conditioning requires this amount of power, resulting in a total energy consumption of 10,753 kWh.

During the same time period, the grow lights will absorb the lion’s part of the costs47,300 kWh.

However, with careful planning, air conditioning costs can be kept to a minimum. When you bear in mind that the system must be constructed for peak load, you can save money on air conditioning by scheduling your grow lights so that they aren’t all on at the same time. If you have a 100-LED lighting system that produces 190,000 BTU/h during a 12-hour period, you’ll need 16 tons of cooling. An eight-ton air conditioner will suffice if the lights are evenly distributed to two different grow rooms, one of which can be operated from 8 a.m. to 8 p.m. and the other from 8 p.m. to 8 a.m.
