1000 Watt HPS/MH LED Equivalent – Metal Halide LED Replacement

(Last Updated On: August 6, 2021)

Indoor gardening has become widely popular nowadays. Especially in the southern region like south Dakota where it gets cold a lot. Plants don’t get enough sunlight to grow. A great alternative for it is indoor gardening using the grow light. That is to say, you can use it in any part of the world.

For years HPS and Metal Halide bulb or better known as MH grow lights have been known as the king of sunlight replacement. Especially the 1000 watt variant. But now a new advanced led grow light technology has captured the market for its multiple advantages. LED light is the new ruler now.

And if you are an HPS or MH user and thinking about shifting to LED system, there is one question that will definitely come to your mind before making the exchange. What is the 1000 watt hps led equivalent? Or the MH substitute. Well, I am here to give you the full info about just that.

What makes me qualified to talk about this?

Well, after five years of using the HPS grow light for my plants, I myself switched to LED system for better light output and cost. So let me share my findings and information with you.

Some Important Facts About led Grow Lights

Before getting to the main part you need to familiarize yourself with some important terminology. Otherwise, all the information will overwhelm you.

Note: If you already have a clear idea about spectrum, LED, HPS & MH light then you can just skip ahead.  Otherwise, stick with us for a little while.


Spectrum means a group of colors ( Like a rainbow)  generated by the severance of the elements of light by their divergent multitudes of deflation keeping in line with the wavelength. As for indoor gardening, these electromagnetic wavelengths (Spectrum) made by a light source are utilized to enhance plant growth. Basically, it helps in the photosynthesis method.

So what is Photosynthesis?

Well, Photosynthesis is the method where trees turn light into chemical energy. In this process, plants use light in the photosynthetic active radiation (PAR) region of wavelengths at the rate of  400nm-700nm. Nm means measured in nanometers.

Spectrums of the lights affect plants’ development distinctively depending on various things like species, the growing environment, conditions, etc. Chlorophyll is the main component that contributes mostly to converting light into chemical energy.  This Chlorophyll mostly soaks up blue and red light spectrums for the photosynthesis process. Both of these colors vastly comprise a large portion of the PAR range.

Now let’s talk about the three main lights in this Article.

What do you mean by Metal Halide bulb?

So basically, Metal halide grow light is a kind of high-intensity discharge light (HID). The MH bulb is an elegant white light. The spectrum mostly consisted of blue and also a significant portion of green wavelengths. It also has a solid amount of yellow and orange and a tad bit of red. This combination of colors makes it exceptionally fruitful for growing plants.

However, we recommend that you don’t use it on the plants that produce flowers. And if you want to use it on the plants that flower then do it on the vegging stage. Flowers and MH don’t mix well. Examples of such Non- flower plants can be ferns, lettuce, various herbs, etc.

Metal halide bulbs in total will last almost 20,000 hours. However, gradually they degrade so much that they don’t give any utility as a grow light. On their better days, they produce an entrance amount of heat and have a towering lumen generation.

All in all, MH lights are highly efficient for plant growth. Although, they are less efficient than HPS (high-pressure sodium) or LED. That is why we are looking for the 1000 watt metal halide led replacement.

What is an HPS light?

High pressure sodium or Hps bulbs are considered as one half of the normal high intensity discharge grow light system. HPS mainly produces a red spectrum. After entering the flowering stage, this sort of bulb replaces MH bulbs. For over 50 years this light has been the household product of every indoor gardener of every level.

HPS grow lights generate a huge amount of heat. So plants that can not tolerate excess heat should not come close to its vicinity. While selecting a HPS grow light, you should use the watt matrix to access the coverage area of the bulb.

From 150-1000 watt you will get a lot of options.  However,  1000-Watt HPS grow lights are the recommended choice as they are dynamic and embed a wide section of about 49 sq. You should install the bulb 6 to 34 inches away from the plant, depending on its type and.

Before starting indoor gardening or planting an existing tree in the garden, do thorough research. Otherwise, you might burn the plant by placing the light too close or harm the growth process by placing it too far.

Why Use LED Light ?

Light emitting diodes or better known as LED is a powerful modern tool for indoor plant growing projects. A unique microchip is included in the bulb. How that works is, the electricity flows to that microchip, and makes it illuminate. These grow lights also have a neat cooling system. So you can touch the bulb with your free hand.

You can say that the LED lights are the preferable choice compared to any other grow light in the market. That’s why we are looking for a 1000 watt equivalent led light, Right? Their regular efficiency rate is above 20%.

The 2021 models have an even higher efficiency rate ( About 60%).  This light is more focused and with distance, they don’t deteriorate. So the outcome is that you can place it as far or as near as you want. The light spectrum is customizable to your needed color spectrum. The options are numerous and coherent.

This growth enhancement bulb is beneficial for the environment as well as your pocket. Most quality LEDs will serve you for 50,000 hours or even more. Bulbs.com, a highly specialized website laid out a pretty solid logic. Suppose, every day you keep your LED grow light on for 12 hours, and the lifespan of that light is 50,000 hours. You would get nearly a decade of utility out of it.  Pretty neat!

1000 watt Hps Led Replacement

Much debate has been done on the topic of HPS vs LED. And if you have read through till now you will clearly see the votes lean towards the LED side. What we will discuss now will solidify the groundwork of LED even more. That is the power consumption mechanism.

Okay so in Contrast to HPS bulbs, you can employ much lower wattage LED grow lights in your indoor garden. But the lower watt percentage has higher work efficiency than other similar wattage lights. As per the ACEEE, short for American Energy-Efficient Economy, there are different dramatic methods of energy conserving.

The High pressure sodium (HPS) 600 watt (W) is equivalent to a 360 W LED.  So by applying simple mathematics, we can easily calculate 1000 watt hps led equivalent.  The result is 600 watts. So in 600 you are getting the same power of 1000 Hps.

Moreover, the yearly savings in an indoor garden if you operate it the whole 365 days a year amounts to 2,600 kilowatt-hours. So in that sense, if you replace a 1,000 Wattage HID bulb with a 600 Watt LED, you will be able to save approximately 2,300 kWh annually. 

1000w metal halide bulb led equivalent

It is apparent that HPS lights are less efficient compared to LEDs. And HPS to some extent beats MH. So according to that logic LED is even more powerful than metal halide bulb. For this reason, you can replace a 1000 watt MH light by only needing to buy a 400 watt LED bulb. To be safe be sure to check the lumen converted ratio.

1000 Watt Metal Halide Lumens vs LED

I have already given you the watt equivalent, to be honest. But in reality, LED replacement for 1000 watt metal halide bulb is evaluated on the standpoint of the amount of lux they can produce compared with Metal Halide bulbs.

What is this lux?

Lux is the amount of light emitted by a source. Basically, the brightness of the lux is calculated on lumens rather than watts. LED produces a brighter light than its ancestors. So the lumen created by the microchips in the LED lights is more effective and prominent than that of the Metal Halides grow lights.

The lumen concept is different from watts. Only in terms of MH light, you will come across it. You should probably look at the ratio lumen the grow light is competent to gather before making the change.

For instance, premium LEDs have a ratio of 1 to 2.5.  It means that you need to purchase the led grow light of 400-500 wattage, as a 1000 watt metal halide led replacement.

Now, let’s compare the lumen ratio between MH and LED. For each MH watt, the lumen amounts to 60 to 110 watts. A 1000 wattage metal halide light produces 50,000 – 100,000 lumens. In the case of  LEDs, the efficiency amounts to 140 lumens per watt. Since 400 watt LED replaces 1000 watt MH, the 400 LED has about 56000 lumens. Which seems accurate.


1. WHAT LED is equivalent to a 1000W HPS?

Around 600 – 700 watts of LED is equivalent to a 1000W HPS.

2. What LED light is equivalent to 1000W halogen?

200W LED light is equivalent to 1000W Halogen.

Halogen light is a sort of incandescent lamp. But they are far less effective than any sort of high intensity discharge light.

3. How many lumens does a 1000 watt LED produce?

Per watt produces 140 lumens. So 1000 watt LEDs produce about 140,000 lumens.

4. How many lumens is a 1000 watt hps?

Well, a 1000 watt hps produces about 110,000 – 130,000 lumens.

5. Are LEDs better than HPS?

LED beats HPS by the long shot. In many ways, LEDs are better than HPS.

LED fixture produce less heat, less expensive and little bill. But most of all you can use this light in any plant growth stage.

6. How many plants can a 1000W LED light grow?

1000W LED light can grow 6 plants altogether.

Mostly, it means that it covers that much area. But, it depends on what type of plant you are growing too.

7. How many plants can a 1000W HPS light grow?

1000 watt HPS light can cover up to 4 to 5 plants and help them grow.

Again they highly depend on plant type and structure. 

8. How much heat does a 1000W led grow light produce?

Every day the 1000W LED light produces 15% visible heat. Although, if you touch it, you won’t find that much heat at all.

9. How much area does a 1000 Watt HPS light cover?

Apparently, a 1000 watt HPS grow light has a coverage of 49 square feet. It may vary depending on your Product brand.

10. How much does it cost to run a 1000 watt metal halide light?

Metal halide bulbs can be expensive and it generates more bills. A 1000 watt MH light can cost nearly 41.22 per hour.

11. How much electricity does a 1000w LED light use?

A 1000w LED consumes 10 watt electricity per hour. So if you run it for 12 hour then daily it consumes 120 watt.

Final Thought

The plants deserve your best efforts. They help us in many ways, right? So getting the best item should be your top priority. So converting into the LED is the right choice. And from this article, I hope you got everything you need to make that decision.

So now, just get your 1000 watt hps led equivalent or MH led equivalent from your preferred store (Some premium brands are also allocating free shipping facilities in different E-shops.) Read the information carefully before shifting your equipment.
