HPS/MH equivalence

66 products

What is the HPS/MH equivalence in LED for indoor growing of plants?

It is important to understand the HPS/MH equivalence in LED when selecting lighting for growing plants indoors. HPS and MH are types of mercury vapor lighting used in indoor growing of plants, while LEDs are becoming increasingly popular due to their low power consumption and low heat output.

Understanding Watt Equivalence

HPS/MH LED equivalence is measured in watts, which means it is important to understand the wattage of each type of lighting. In general, it is recommended to choose LED lighting that has an equivalent wattage to the HPS/MH lighting you were previously using. For example, if you were using 400 watt HPS lighting, you should look for 400 watt LED lighting for similar area coverage.

Consider light needs

It is also important to consider the light needs of each plant species when selecting LED lighting. Some plants need more light than others, and it's essential to make sure you're providing your plants with the light they need to thrive. Be sure to learn about the light needs of each plant species and choose LED lighting suited to those needs to ensure optimal growth.


In conclusion, HPS/MH LED equivalence is an important element to consider when selecting lighting for growing plants indoors. Be sure to understand the wattage of each type of lighting and consider the light needs of each plant species to select the right LED lighting for your needs and ensure optimal growth of your plants.
