LED vs Fluorescent Which is better? WattLogic


When it comes to indoor gardening, choosing the right grow light is crucial for the health and growth of your plants. Two popular options on the market today are LED and fluorescent lights. In this article, we will compare these two types of grow lights and help you determine which one is best suited for your needs.

What are LED Lights?

LED stands for Light Emitting Diode. LED lights are a type of solid-state lighting that uses a semiconductor to convert electricity into light. They are known for their efficiency and longevity. LED lights are available in various colors and spectrums, making them ideal for different stages of plant growth.

What are Fluorescent Lights?

Fluorescent lights, on the other hand, use a gas-filled tube to produce light when an electric current is passed through it. They have been used for indoor gardening for many years and are known for their affordability and versatility. Fluorescent lights are available in two main types – T5 and T8 – with different sizes and wattages.

Comparison: LED vs Fluorescent Lights

Energy Efficiency

LED lights are highly energy-efficient, converting a higher percentage of electricity into light compared to fluorescent lights. This means that LED lights consume less electricity and produce less heat, making them more cost-effective in the long run.


LED lights have a significantly longer lifespan compared to fluorescent lights. While fluorescent lights typically last for around 10,000 hours, LED lights can last up to 50,000 hours or more. This means fewer replacements and lower maintenance costs for LED lights.

Light Spectrum

LED lights offer a wider range of customizable light spectrums compared to fluorescent lights. This allows you to tailor the lighting conditions to the specific needs of your plants at different growth stages. Fluorescent lights, on the other hand, have a fixed light spectrum that may not be suitable for all types of plants.

Heat Output

LED lights produce significantly less heat compared to fluorescent lights. This is important for indoor gardening as excessive heat can damage plants. LED lights allow you to place them closer to your plants without the risk of overheating, providing better light distribution and coverage.

Initial Cost

LED lights generally have a higher upfront cost compared to fluorescent lights. However, considering their energy efficiency, longer lifespan, and lower maintenance costs, LED lights can be more cost-effective in the long run.

Light Intensity

LED lights provide higher light intensity compared to fluorescent lights. This means that they can penetrate deeper into the canopy of your plants, promoting better growth and higher yields. Fluorescent lights may not be able to provide the same level of light intensity.

Environmental Impact

LED lights are considered more environmentally friendly compared to fluorescent lights. They do not contain mercury, which is present in fluorescent lights and can be harmful to the environment if not disposed of properly. LED lights are also recyclable, further reducing their impact on the environment.


Both LED and fluorescent lights have their advantages and disadvantages when it comes to indoor gardening. LED lights offer higher energy efficiency, longer lifespan, customizable light spectrums, lower heat output, and higher light intensity. On the other hand, fluorescent lights are more affordable upfront. Consider your specific needs, budget, and the type of plants you are growing to determine which type of grow light is best for you.
