Lumens, Watts and Wavelengths – Understanding the Real Values of Grow Lights

As a consumer, you are unfortunately at the mercy of marketers throughout the world, who can take some of the most mundane or redundant information and somehow convince you that you will be investing in real value. This is perhaps more true within the indoor growing industry, as many rumors and a lot of false information has been spread over the years, in an attempt to persuade unknowledgeable consumers into purchasing lower quality products.

As such, this article aims to address some of that false information, so that you can get out there and purchase the best possible lighting for your unique growing needs.

Avoiding the Common Marketing Schemes of Lighting Companies

In a similar way to a scientific equation, without all of the necessary information, you can’t actually work out how efficient or effective a light is – unless you perform tests yourself. As such, finding out only the lumen rating or wattage essentially tells you nothing – because without all of the above, as well as a few more specifications, you only have a small part of the overall equation. So don’t be fooled by marketing schemes that try to persuade you with impressive sounding lumen ranges or high watt usage, as many of the companies who focus on that kind of information are often trying to hide their true effective value.

How Lumens and Wattage Affects Performance

If you are an avid grower, you may be surprised to find out that these ratings don’t actually affect the performance of lights. In fact, two of the above specifications are essentially only valuable to humans. So let’s find out more about these spec’s, as well as why you should never purchase products based solely on these specific qualities:

Lumens – If you are installing aesthetic lighting for your home or entertainment areas, the lumen rating can be important, as it basically describes how the lighting will look to a human eye. Plants, however, don’t care much for aesthetics, but rather simply about how many protons the source delivers to their receptors. As such, unless you are eager to make your indoor grow look aesthetically pleasing, lumens are one of the last variables you should be considering for plant growth.

Watts – In a similar fashion to evaluating vehicle performance, you can’t judge the value of a light by simply looking at the fuel consumption. In fact, two completely different lights – or vehicles – may have the same fuel input, while having wildly differing outputs. The real value is how efficiently and effectively the product utilizes the fuel, as well as the end result of it. Ideally, you want a light that not only provides sufficient energy to your plants, but also operates at a low wattage in order to get the best value of money.

When shopping for lighting, find suppliers like who are capable of providing the information you need, such as the PPF ratings, PPFD maps and input/output watts. This way, you don’t have to waste time or money on lesser quality products, and can instead acquire the right lighting for your needs without extra hassle.
