Buying Guide

As you have figured out the number of wattages needed for your LED grow lights beforehand, this means that you are already on the right track. However, there are still many other factors that you will have to keep an eye on. To get the best 600W LED grow lights for your needs, consider the following aspects:

Actual wattage: Contrary to popular belief, 600W LED grow lights do not necessarily have to use the exact wattage number of 600. In fact, most of them will use around 400W at their maximum capacity. Options that use higher actual wattage than that will emit brighter output, but cost more in terms of electricity bills.

A clear advantage that LED grow lights is that they offer dimmable switches to fully customize the lighting intensity to your needs and save electricity costs if needed. Different stages of growth will require different brightness for optimal results, and that is where the dimmability of your LED lights comes into play.

Light spectrum: With your LED grow lights, you want to mimic the natural light for your plants to reach optimal growth. Different colors will have different impacts on the plants. You would want to have a good amount of color options to fit every stage of the growing process.

For the spectrum that your LED grow light has, make sure that all the plants under it will get the same spectrum to avoid any unexpected results.

Coverage area: There are a lot of factors to consider when it comes to determining the perfect coverage area for your LED grow lights. Obviously, you would want its size to be large enough to cover all your plants, but this does not always result in the most compact grow light. If you have enough space for storing it and do not have to frequently move everything around, then portability should not be a problem.

However, if you want something lightweight and portable, take that into consideration, but do not compromise on coverage size by any means.

Heat management system: When it comes to your grow lights, excessive heat can spell doom for your plants. Fortunately, LED lights are known to be the superior option due to the least amount of heat generated. If you plan to use yours for longer periods of time, be mindful that they can still produce some heat.

In this case, try to stay on top of your situation by choosing options that come with good heat management systems. Whether they come in the form of fans or heat sinks, there is no doubt that they can help relieve some of the heat that can be harmful to your plants.

Accessories: More advanced LED grow lights come with additional that can be helpful when in use, which is why you should purchase them along with the light itself rather than buying them separately afterward. They can either help you install your lights more easily, or elevate the functions of your grow lights to a new level, which should be the way to go if you want to get the best out of your investment.

Reliability: Up to this point, everybody knows that growing the plants indoors requires high-quality grow lights. For such significant investments, you do not want your options to be inferior in terms of quality or unreliable after a short time of use.

For this reason, check for warranties as well as various ratings and reviews from other customers to ensure you are getting the best possible option.


How is LED grow lights compared to HPS units in terms of canopy penetration?

Most LED grow lights’ manufacturers tend to be quite positive about their products’ ability to deeply penetrate below the canopy. Sometimes claim that they can surpass their HPS counterparts in this aspect.

The truth is, LED and HPS grow lights are actually quite similar when it comes to canopy penetration. However, there are a few advanced LED units that manage to come out on top which is why they are very much sought after by customers.

Can LED grow lights hold their own against HPS options when it comes to the level of brightness?

As mentioned before, LED lights will not use 600 watts of power to operate. The way they are called, “600W LED grow lights” refers to the fact that their lighting output is equally strong as 600W HPS grow lights.

However, LED lights are the superior option when it comes to energy efficiency. The fact that they can still deliver the same level of brightness compared to other alternatives while using less energy speaks volumes to why they are so beloved.  

What are the major benefits that LED grow lights equipped with IR and UV rays?

LED grow light options that come with ultraviolet and infrared rays have become the modern choice for so many consumers out there. This is mainly down to the fact that their grow lights have more weapons in their arsenal to fight back against diseases and pests on the plants.

These problems have become increasingly challenging to take care of once people start to grow plants indoors. But with these 2 types of rays, you will not have to stress out about them anymore.

What is the ideal number of colors that your LED grow light should have?

For LED grow lights, more color options will result in less effectiveness in the light emitted. This is why you should not go over the top when it comes to colors, because in the end, you will not be able to utilize them all anyway. A solid one with about 6-8 colors is more than enough to take care of your needs.

What to look for in your LED grow lights warranty?

For any types of LED grow lights, there is always the risk of malfunctioning within the estimated lifespan (of about 30000-50000 hours). An LED grow light that comes with a warranty of about 2-3 years will make sense, because this period is about half the life expectancy of your unit and can save you from wasting your money in the initial years. If you can find options that come with a 5-year warranty, that is even better.

Final Thoughts

LED grow lights are the premiere trend in indoor plant growing, and for good reasons. With a good option in hand, taking care of your greens with the right lighting condition has never been easier – and with the numerous remarkable characteristics that LED brings to the table, you are bound to be satisfied with the results that they bring.
