Are CFL grow lights any good?

CFL lights are undoubtedly the best type of grow lights you can use. Besides, it is quite popular as a household light. 

CFL lamps are highly favored by gardeners as they work amazingly well for growing indoor plants too. These bulbs emit a great amount of light, produce low heat, and are cost-effective. Besides these lights are cheap and widely available.

What is better CFL or LED for growing?

It’s difficult to choose one over the other as both have their advantages and disadvantages. LEDs have a full spectrum of light and are highly versatile. These can be installed both indoors and in your grow garden.

However, they are more expensive. CFLs are low-priced quality options that are readily available. These work great for low-cost grow tents and are ideal for growers who have just started. 

A detailed rundown of both LED and CFL lights will help you get a clearer idea: 

Energy efficiency: LED lights are more energy efficient than CFLs. 

Some LED lights can be placed closer to the plants and thus they make way for more photosynthesis. But the same does not happen with the CFLs. It’s best to keep them far away from the plants for the high temperatures they produce.

As the distances between the plant and light increase, less energy is available for photosynthesis. The running rates of energy are lower for LED lamps compared to CFLs. However, LED lights are more expensive than CFLs. 

Best CFL Grow Lights Buying Guide

The sheer number of options available in the market is very confusing. However, getting just any CFL light will not solve your concerns.

Thus it’s important to look into a few factors before you make your purchase of best CFL grow lights 2023. 

Best CFL Grow Light Buying Guide

The wattage of the CFL

Wattage is the amount the electricity the bulb will require to produce light. Of course the more wattage the bulb has the more light it will emit. A high-watt light is surely good for your plants. 

CFLs are best for use in small spaces. Ideally, a bulb with a wattage of 80-90 per square foot should be good. A bulb with that wattage should be beneficial for 1-2 plants growing in an area.


Lumens are the amount of visible light produced by a bulb per square foot. This essentially follows the same principles as wattage.

As a rule of thumb- the higher the lumens, the more light the bulb emits. For CFLs up to 10,000 Lux is good as long as your space can accommodate the heat. 

Color and temperature

Color temperature is measured in Kelvin and is one of the most important metrics. This light spectrum is important as Photosynthesis depends on it. For the process to work seamlessly, the CFL should emit within 2700K to 6500K wavelengths.  

6500K appears as cool daylight. This light is ideal for use in the vegetative stage. 2700K appears warm or soft warm. It’s best for after the vegetative stages.

Indoor/outdoor CFL

Do not be under the impression that all CFLs are best for both indoor and outdoor use. Some CFLs are designed for indoor use. Such bulbs can only tolerate temperatures up to 20 degrees F along with other elements. 

Outdoor-specific CFLs have additional protection. Thus they can tolerate harsher conditions. Owing to the different build of both indoor and outdoor options- make sure you select ones that are suited to your needs. Always check labels before purchasing. 


Certification like Energy Star is an important certificate to consider. It implies that the product aligns with the quality standards and is this safe for use.

The quality of the bulb and the light has a great impact on your garden. Most CFLs available in the market have a fewer number is lumens, wattage, and kelvins. 

But that’s not the ideal measurement. 

  • A proven measurement for tracking the effectiveness of your CFLs is PPFD or DIL. 
  • PPFD also known as photosynthesis photon flux density is another unit of PAR. 
  • DIL or daily light integral is the total amount of photons in a full photoperiod. 
  • But most manufacturers don’t mention these two units. 
  • It’s crucial to search for blubs that mention two of these units.

Frequently Asked Questions (FAQs)

Can I use CFL for flowering?

Yes, you can. But plants require additional care when it comes to light and temperature during their blooming stage. You will require a low-power light that produces white color. Thankfully, CFLs of this category are available.

How many CFL lights do I need for one plant?

It’s best to opt for 150W of CFL per plant and stick to smaller-size bulbs if possible. You can use the regular bulb sockets too, only make sure you are using the ones with a medium base.

How far should CFL lights be from seedlings?

Since light is emitted from all around the bulb, it’s best to utilize as much of that light as possible. It’s best to keep the plants 4-6 inches away from the plants to ensure maximum utilization of the illuminated light.

Can I use regular CFL bulbs to grow plants?

Yes. In fact, any CFL light can function as a grow light. It’s essential to get a higher wattage than the ideal color. As for the light spectrum, it has been observed that blue leads to a shorter vegetative growth while red and yellow encourages a longer one.

How many watts CFL for seedlings?

Seedlings mostly require around 100 watts per square foot of growing area. In addition to the watts, they require the right color temperature to grow and thrive as well.


Best CFL grow lights are pretty popular among growers, especially beginners. In this article, we have covered all that you need to know to grow your plants using LED lights.
