When looking for the best indoor grow lights, one of the most important is to first determine what type is needed. In this case, the followings are some of the choices that you will be confronted with:

  • Incandescent: This is the traditional option for grow lights, which also happens to be the cheapest. They are tungsten filament bulbs, the same ones that are still found in many homes today. They are suitable for vegetables.
  • Fluorescent: With a lifecycle of about 20,000 hours, its price is slightly higher than what you would spend on incandescent light bulbs. They can be placed even close to the plants because they create no or minimal heat.
  • High Intensity Discharge: More popularly known as HIDs, they have been around since the 1960s. They are available in different types, including High Pressure Sodium, Low Pressure Sodium, and Metal Halide lamps. They can produce a lot of heat, so additional ventilation will most likely be required.
  • Full-Spectrum Fluorescent Lights: This is basically like a fluorescent light, except for the fact that it is more innovative. However, there are many people who stay away from this option because of its high cost.
  • LED: They are amongst the most innovative options within the product category and gained reputation because of their energy efficiency. They are not only small but also easy to mount. They have exceptional lifespan and can be dimmed. There is no wonder why there are many people who believe that this is the best choice when it comes to indoor grow lights.

Essential Factors to Consider

When searching for indoor grow lights, the different factors that will be mentioned in this section are some of the most important to be taken into account.

1. Cost

For most people, the first consideration when choosing a grow light is the price. More often than not, many will be tempted to choose the cheapest product that is available in the market. However, keep in mind that price is not always enough consideration. More often than not, if the grow light comes with a cheap price, the operating costs in the long run will be higher. It is better to use more expensive grow lights because in the long run, they consume less energy, and hence, they will be cheaper to operate. In addition, if you want excellent quality, be ready to spend more!

2. Feedbacks

Having a hard time deciding which one to pick for the best indoor grow light? One thing that you should do is to read the reviews of other people. You can go online and look at what others have to say about a specific product. You can also ask around from family and friends who have used grow lights in the past. You can use their opinions and experiences to differentiate your options, making it likely that you will end up with a decision that you will not regret.

3. Light Intensity

You should also consider the specific types of plant that you will grow, and based on this, choose the light intensity that will prove to be appropriate. Many seedlings may not grow regardless if they are directly exposed to sunlight. This is where the use of grow lights enters the picture. In order to determine the light intensity, take a look at the wattage of the bulb. Aside from the wattage, you can also consider how close the bulb light will be positioned on the plant in order to gauge its intensity.

4. Lifespan

You should also consider how long the light will last, which will be indicative of value for money. If you want it to provide the best bang for the buck, make sure that it is going to withstand many years of use. Incandescent light bulbs have a lifespan of 750 to 1,000 hours, 20,000 hours for fluorescent grow lights, and more than 50,000 for LED bulbs. The latter is the best choice when looking about lifespan, even if its cost is typically higher than other options in the market.

5. Energy Efficiency

For many people, there could be hesitations with the use of grow lights because it is going to consume electricity. With the rising costs of energy, this is surely a valid concern. Therefore, more than just being budget-conscious, but also demonstrate your efforts to promote environmental sustainability, you should choose grow lights that are energy-efficient. This gives you another good reason to consider LED above other alternatives. It can deliver optimal performance in the absence of consuming too much energy. This is easy for the wallet and good for the environment.
