MH vs HPS: Difference and Comparison

At the very beginning of human civilization, people used to utilize fire as a mechanism to light their surroundings. But with the growth in time and technological advancement, we now have electricity in our homes. This electricity helps human civilization to light its complete infrastructure. But the system of electricity is of no use without accompanying it with certain equipment such as light bulbs and rods.  

MH and HPS are two types of electric bulbs that are widely popular all across the world, but due to the similarity in the pronunciation of their names, some people tend to use them interchangeably. However, in reality, these two are completely different from one another and serve different purposes. 

Key Takeaways

  1. Metal Halide (MH) lamps produce a broader light spectrum, while High-Pressure Sodium (HPS) lamps emit a more narrow and focused spectrum.
  2. MH lamps are better suited for vegetative growth, while HPS lamps excel in promoting flowering and fruiting in plants.
  3. HPS lamps have a longer lifespan and are more energy-efficient than MH lamps.

MH vs HPS 

The difference between MH and HPS is that the previous one, upon lightning, produces a light similar to a mixture of blue and white, but on the other hand, the latter one produces a light similar to amber colours. Apart from this very basic difference, these two differ from one another in terms of their other attributes, such as the capacity to produce lumen, etc. 

MH vs HPS

MH is an acronym for Metal Halide. It represents a widely popular variety of bulbs used for almost all purposes all across the world. In the bulb replies, mockery and metal can be found as the contents, and therefore it is very useful in many applications. It is not just limited to providing light in many places because it helps in the growth of certain plants as well by providing sufficient light for their growth. 

But on the other hand, HPS stands for High-Pressure Sodium bulbs. Similar to the previous category of bulbs, this one also falls under the umbrella term of high-intensity bulbs. As far as the use of this particular bulb is concerned, it is most likely to be used for either photography or growing certain plants because of the amount and quality of light produced by this particular bulb. It has many significant qualities and can be helpful in many scenarios.

What is MH? 

The term MH stands for Metal Halide and represents a variety of high-intensity bulbs that are widely popular all across the world nowadays. Developed in the year 1960, this bulb is said to be one of the most revolutionary bulbs of its own kind.  

In the inside part of the bulb, vaporized mercury and metal halides can be found that provide the bulb with a base for further providing bright light and lumens. When lighted, the bulb produces a unique light that resembles a mixture of blue and white light. However, even after providing such a bright light, the lumens of the bulb are relatively low quality.  

A very significant feature of this bulb is that its utilization is not limited to just one sphere. Rather, it can be used in almost all possible industries. From lighting places like houses and other industries, this bulb is also used as a helping hand in photography, etc. Due to this particular utility, the cost of this particular bulb rises slightly, and it can be expensive for certain people.

What is HPS? 

HPS is an abbreviation for high-pressure sodium bulbs and happens to be a member of the high-intensity family of bulbs, and is widely preferred by many people residing in different areas of the world. Although this particular bulb resembles the other variety of high-intensity bulbs to some extent, it can still be widely differentiated from those bulbs in terms of its features and uses.

Talking about manufacturing of this particular bulb, it contains a mixture of metal and glass in the very core of the bulb. Due to this particular attribute, it produces a very bright and shiny light. There are places where this bulb has been used to light streets or houses, but in most cases, it is used for either photographing certain items or growing certain indoor plants, as it produces the exact right amount of light.  

Another major reason behind the popularity of this bulb is that it is relatively less expensive and therefore reduces the cost to the person who is employing the bulb. However, a shortcoming is also attached to this bulb the life span of this bulb happens to be a little shorter.

Main Differences Between MH and HPS 

  1. MH refers to a variety of bulbs, also known by the name halide metal, but on the other hand, HPS refers to a variety of bulbs, also known by the name high-pressure sodium bulbs. 
  2. It produces a color that looks like a mixture of blue and white but, on the other hand, produces certain amber shades of colors. 
  3. MH ones happen to be more expensive as compared to HPS ones. 
  4. In terms of efficiency, MH bulbs happen to be more efficient than HPS bulbs due to their many in-built features. 
  5. Metal halide bulbs can last so much longer even after their extensive use, but on the other hand, high-Pressure Sodium bulbs run out of their life after a short span of time, and this counts as a major disadvantage.
