What are the pros and cons of LED or HPS grow lights?
As each grower knew that there’s a lot of debate among growers about whether HID lights (HPS and Metal Halide) are better or worse than LEDs. The truth is, one isn’t holistically better than the other, it just depends on your needs and priorities for your growth. Take a look at the comparison table below to help you understand what type of lighting is best for your growth.
Comparison of LED or HPS grow lights:
|LED Grow Lights||HPS Grow Lights|
|More energy efficient. LED grow lights can produce as much as twice the light output for the same power consumption.||Less energy efficient. HPS lights consume more energy than LEDs to produce the same light output.|
|Longer lifespan. LED bulbs last longer than HIDs meaning you have to replace them less often.||Shorter lifespan. HPS lights diminish in intensity faster than LEDS, and need bulbs replaced every 12 – 18 months.|
|Low heat output. LEDs run colder than HPS and require less ventilation maintain healthy grow room temp.||High heat output. HPS lights run hot and often require additional ventilation to maintain healthy grow room temp.|
|Good for closet or beginner grows. LEDs typically come as compact, all-in-one fixtures, making them better for small spaces and closet or tent grows.||Good for large or professional grows. HPS lights provide high-intensity/high-yields and versatility to swap out bulbs with MH to change spectrum between veg and flowering.|
|Higher up-front cost. LEDs typically cost more up-front, but save money in the long run due to longer lifespan and lower energy consumption.||Lower up-front cost. HPS lights are typically cheaper watt-for-watt, but this gap in cost has been closing.|
|Harder to shop for. The quality and specs of LEDs vary highly across manufacturers, requiring more research when you shop.||Easier to comparison shop. HPS lights have been around longer and are more standardized across manufacturers.|
Longer Life Span LED or HPS grow lights
Another major advantage of LED or HPS grow lights technology is their longevity. Our grow lights can last 50,000 hours before their light output is significantly reduced. This means that on average grow lights using LEDs can have close to 10 years of normal use (12hrs On – 12hrs Off) before they need to be replaced. For comparison, the lamps used in HPS grow lights are typically swapped after only 12 months of normal use and can cost over $100 to replace. Even with their lower initial cost, in just a few years HPS grow lights can become more expensive than LED lights once the cost of replacement lamps is factored in. When you also take into account the additional savings LEDs provide by being more energy-efficient, less demanding on cooling systems, and eligible for rebates, LEDs are the more cost-effective lighting solution.
