Pay Attention to These Things When Buying LED Grow Lights

If you're new to indoor gardening and buying LED grow lights seems overwhelming with all the features and ratings manufacturers publish, don't worry! Manufacturers of LED grow lights often publish a litany of features and ratings, which can confuse beginners in indoor cultivations. There are some key things you need to look for that will make it easier for you to choose. With a little bit of knowledge, you'll be able to narrow down your options and find the perfect LED grow light for your setup.

 

Light Output 

Some LED grow light manufacturers may publish inaccurate PPF and PAR ratings, affecting how your plants respond to the light. In some cases, grow lights only put out a single PAR rating, which is only a measurement in the middle of the grow light’s footprint. Unfortunately, this doesn’t represent the whole grow light, as you also need to consider the surrounding areas.

Aside from buying from a reputable brand, it would be best to consider looking at independent lab reports that test these grow lights. Often, these tests are published on the product page of an LED grow light. You can use this as a guide to check for the accuracy of the information published on a product page.

You can compute the average PPFD of the grow light from the PAR readings published in these reports. The average PPFD should show you how much light you get with the grow light.

 

Grow Light Wattage 

The wattage of the grow light matters since you’re looking at consuming less while getting more. Remember, that’s the whole point of going for LED grow lights because you want to save in power consumption.

Now, there’s often a five percent discrepancy between the wattage published. Knowing the actual wattage matters because that will translate to power consumption and heat emissions in your grow space.

The good news here is that independent labs report the wattage of a grow light and at what voltage a grow light is tested. The voltage matters because running a grow light with a slightly higher voltage will result in lower wattage.

 

Diodes Used 

While not common, some companies use higher-quality diodes for the test unit and switch to a lower-quality LED array. This deception can lead to inaccurate results, which can affect the growth of your plants.

Buying from a reputable company or dealer is the best way to prevent this. You can also ask for the lab report conducted independently to ensure you get the suitable LEDs in your grow light. Compare the lab results with what the manufacturer publishes for the product specifications.

 

Diode and Driver Lifespan 

The LEDs in a grow light have a lifespan of 50,000 – 100,000 hours. However, the drivers of these grow lights tend to have a shorter lifespan. If you’re buying an LED, grow light, look for one that uses an external driver so that you can move around to ensure air circulation. Preventing it from overheating is the first thing you must consider to ensure its longevity.

But at some point, the drivers are bound to fail. Now, drivers are easy to replace. But before you fork out some money to buy a replacement driver, consider going over the warranty coverage of your drivers. You might be qualified for a repair or even a replacement.

 

Warranty Length 

Sometimes you end up with a lemon or a defective product. While many LED Grow Light brands do their best to ensure quality control, there are instances that a defect may happen after the inspection, such as in transit to your shipping address or, worse, during use.

Always check the product description for warranty information. It’s a standard operating procedure to publish the warranty information of the grow lights on this site to ensure confidence among buyers.

Sometimes, two sets of warranty coverage will cover a particular part of the grow light. It’s best to verify this information, so you know what is covered. Remember to note the date the grow lights arrived, which starts the warranty coverage. If there’s a replacement guarantee, take advantage of it, especially if the defect arises during the replacement period.

 

Which Brands Can You Rely On? 

The good news is that you can rely on plenty of brands to produce accurate results that match independent lab reports.

Here are some brands to consider if you want to buy an LED grow light. Note that these are just some of the reliable brands available today. You can check our selection of grow lights for other options based on the abovementioned criteria.
