Factors to Consider When Buying Growing Lights

What is A Grow Light?

Grow lights are designed to provide the same intensity as that of the sun or deliver a suitable spectrum for a specific type of plant. Plus, it’s a mechanism that lets growers mimic various outdoor conditions such as the temperature, spectral outputs, varying color, and intensity. Various come into play when choosing a good grow light, such as the type of plant, stages of cultivation, and the photoperiod time for the plant.

Three Key Aspects of a Good Grow light

There are a few key factors you have to consider when getting a good grow light. Below is a simple guide to help get you started:


PAR is an acronym for Photosynthetically Active Radiation. Specifically, it’s an effective spectral aspect of plant photosynthesis, and it exists in solar radiation. The wavelength of PAR ranges between 380 ~ 730 nm, which is similar to visible light.

The Coverage Area

This refers to the space or light intensity of your chosen LED. A good LED should provide optimal coverage in your grow room, and ensure you check your chosen light for this feature. Sufficient light means that all the plants in your car can perform photosynthesis.

The Spectrum

Remember to go for a light with a “full-spectrum” rating. Why? It’s because such a light provides high-quality light, which is perfect for photosynthesis. To achieve this, most brands incorporate their lights with as many as 10 LEDs or more to form one light.

How Should I Compare LED Grow Lights?

A simple search on grow lights will expose various factors and features you have to consider when investing in the light. You are likely to have come across multiple types of metrics that brands use to market their products. While there are numerous facets you have to consider, it all boils down to one perspective – a good light offers high-quality light for plants. An excellent way to compare grow lights would be to evaluate the metrics of the light. For instance: 

Avoid Over Focusing on LED Grow Lights

Do you have 5W, 10W, or 15W LEDs? It’s a common question that many growers ask, especially those who are on the hunt for a good light. However, the wattage of the LED won’t provide any useful information because such light’s efficiency varies largely. 

Remember that LED wattage refers to a system input, and it would be much better to ask about PAR output. Thus, a lighting system that features a 10W or 15W LED won’t necessarily provide lighter than a 5W LED.

Avoid Over Focusing on a Single PPFD Measurement

You can only do this if you are growing a single plant directly under the light. That said, a single PPFD measurement won’t be sufficient if you have several plants. Most brands cluster the LEDs tightly and use narrow beam optics to deliver high PAR levels for plants under the fixture. That said, unless you were growing a single plant under this space, it would help if you would also inquire about the PAR levels.

Key Questions to Ask When Buying Grow Lights

  1. How much is instantaneous PAR from the fixture available for the plants under the fixture? (Metric is PPFD)
  2. What is the amount of PAR under the entire light canopy?
  3. How much wattage does the fixture use to produce light for the plants? 

Bestva vs. Viparspectra LED Grow Light Comparison: Final Thoughts

Taking good care of your indoor garden is an important facet of your harvest next season. There are various things you have to do and buy, but it’s all to ensure you get the best yield. Once you get the hang of it, you will find it easy and fun, which is why we recommend we have this Bestva vs. Viparspectra LED Grow Light comparison.
