LED vs HPS: Which is better?

led vs hps

A comparison between these types of light growers has been present since when the LED Grow light hit the market. The technology of the LED grow lights spark a debate on which among the two is the best lighting to be used. Different online groups agree that LED grows lights way better than HPS in terms of luminescence, performance, and efficiency, while others stick to HPS light due to its standardized value. But, the biggest question of them all, which one is better? 

HPS light users over the years resist changing and transferring to LED grow lights due to a higher upfront cost. However, in terms of long-term effects LED grow lights are proven to be more cost-efficient in the long run, as well as its operational cost is a lot cheaper than the HPS. The highlights of this article focus on understanding the differences between LED vs HPS grow lights, its pros, and cons, as well as the comparative analysis between the two.  

Understanding HPS Light

High-Pressure Sodium Lights provide remarkable raw light output it is the best grow bulb available in the market for both beginners and professionals. HPS light emits a huge amount of light perfect for plants undergoing the flowering stage. Typically, HPS lights are reddish and orange. The color spectrum and the wavelength are determined on what type of gas id used in the bulb.

Benefits of HPS light

The initial start-up cost of HPS light set-up is far cheaper compared to LED grow lights, but each year LED grow light setups get more and more affordable. HPS lights are also easy to compare among other product manufacturers available in store because it is more standardized. Since HPS Bulbs emit greater raw light it may result in a greater yield, specifically when working on with very huge plants.

Drawbacks of HPS light

HPS lights are not energy-efficient, compared to LED grow light setups HPS lights uses more electricity to generate light. HPS grow bulbs also must be replaced regularly every 12-18 months, as the bulbs intensely diminish over time, in result to additional cost in operations. HPS lights need additional ventilation equipment to maintain the proper grow room caused by the lights that generate much heat. If the heat that HPS bulbs generate is not regulated properly it may cause difficulty in the growth of plants.

Understanding LED Grow Lights

LED grow lights are the most efficient lighting type available in the market with its outstanding technology. LED grow lights vary in shapes and sizes, this allows users to expand their options in choosing the perfect size to fit in every space. LED grow lights are technically crafted for a wide range of usage whether it will be used in commercial operations and/or hobby gardens. 

LED grow lights is truly energy-efficient, it produces a huge number of yields while consuming less energy compared to HPS bulbs, LED grow lights is also sustainable as it requires minimal maintenance aside from cleaning the light occasionally. Most LED grow lights have spectrums optimized intended for full growth cycle which enables growers to only use one LED grow light system. 

Benefits of LED Grow Light

One of the advantages of LED grow lights is its aspect of being energy-efficient, it outgrows HPS lights in that aspect which uses twice the wattage that the LED consumes. LED grow light units are an all-in-one fixture, which makes it easy to assemble and work in tight areas. LED grow lights also beneficial most especially to indoor growers as it is much cooler compared to HPS lights. LED grow lights can also be placed near the plants without causing any heat damage, this is perfect especially for confined plant areas.

Drawbacks of LED Grow Light

LED grow lights have a higher upfront cost but having this kind of lighting system as the investment may bring more savings in the long run due to its lower operational cost. A comparison to this lighting system is quite difficult since LED grow light is not yet standardized across different manufacturers. Still, the industry has a long way and design practices are becoming more consistent. LED grow light produces very little heat compared to HPS, growers with cooler indoor areas may be needing a supplement extra heat from HPS or MH which are both HID lights.

LED vs HPS: A Comparative Analysis


HID lights like the HPS needs a lot of preparation to place the lighting system well. LED grow light, on the other hand, is very easy to use proper orientation and the right spot is only the key afterward just plug the lighting system then it is good to go.

Energy Saving

Through time HPS gradually losses its brightness and needs to be replaced by new light bulbs a couple of times during the growth cycle. LED growth lights are far more energy-efficient compared to HPS and less often it needs to be replaced by new parts, resulting in saving operational costs and effort.

Heat Efficiency

LEDs are efficient in terms of heat management the lighting system can be placed closer to the plants without having any damage. While HRS emits a huge amount of heat that need for supplementary ventilation in the area.

Life Span

Quality LED Grow light can last up to 50,000 to 100,000 hours 5 times more than the regular lifespan of an HRS bulb that would only last up to 10,000 hours. Cleary, data shows that LED replaced less often and more worthwhile in the long run, growers will never worry about changing the lights for a couple of years.


A 600-watt HRS light yields about 300 grams from the area it covers, technically HPS can produce a ½ gram per watt. HRS falls short the LED growing light can produce which is about 1.5 grams per watt while using less electricity with the same luminosity with the HRS.

Adjustable Spectrum of the Colors

LED grow lights have the utmost advantage in this aspect, compared to HRS LEDs, which do not need to switch the bulb for it to have a different color. The different light spectrum is very important in different growth stages.


Identifying which is better between LED vs HPS is an easy take to decide. Considering the advancement in technology, the equipment that is often used in growing weed should be upgraded as well which makes LED grow lights the perfect piece to illuminate your ideal indoor growing setup for weed. There are valid points that explain why do people remain to choose HPS but we want to consider long-term use as well as its take for energy consumption.
