LED Grow Lights Vs Fluorescent Lights: Which Is Best For Indoor Gardening?

The subject of discussion in this article is the best LED light for 4×4 grow tentwhich is captioned above as well. But in order to determine the best one between LED grow lights versus Fluorescent Lights, we need to differentiate the features of the both. Therefore, we will judge which lights are best for indoor gardening. Prior to that, it is important to know about LED Grow Lights and Fluorescent Lights 


Light-Emitting Diode is known as LED. There are many types and categories of LED lights. LED grow lights are one of them. These lights are energy efficient and mainly used for indoor growers. LED grow lights are not like other traditional lights. It does not burn filament.

Instead, pass light through semiconductors to create a spectrum. LED grow lights are used as a supplement to natural light. If you are interested in knowing more, you may read our another article about LED Grow Lights where you will be able to enrich your knowledge about it.

The history of LED grow lights. We know that it appears around 10 to 15 years ago. This light has been the preferred grow light of serious growers and in horticulture as well.

LED emits heat at a very controlled level and good enough to be absorbed by plants and fruits. So there is no confusion or risk of its high heat performance or overheating. This light is free from burn out.

Though LED grow lights are more expensive than fluorescent. Infact, these are affordable in consideration for a long lifespan eventually 10 times than the fluorescent light bulbs.


Fluorescent grow lights are in fact known as Compact Fluorescent Lamp (CFL). It has been deemed as an effective growing light for indoor plants for years. It is commonly manufactured as a spiral tube connected to a screw-in ballast or base.

New products are different that look like the traditional incandescent bulb. They also come in round and flame shapes.To start producing indoor vegetables fluorescent lights are good. 

These lights typically come in long tubelike bulbs in a range of sizes including T5 and T12. Due to smaller surface area, e.g. narrower bulbs are more efficient and brighter. A 25 watt fluorescent bulb emits about 100-watt incandescent light bulbs. 

T5 systems put out about double the amount of light per tube as standard fluorescent lights. This is a very intense light as 6500 Kelvin and also full spectrum. This is so far in brief about fluorescent growth light. 

Why the Interest of Growers?

Fluorescent lights have a long journey and are widely known to the people. The growers have the interest in many reasons, but mainly for two things are highly taken  into consideration as wide availability and affordability. .

Majority of home hardware and light shops sell the T5 tubes at a very reasonable price. The first time growers would most likely buy this one for test basis. 

On the other hand, the indoor growers might be thinking about the features and performances as less efficient and actually diffuse lights, heat output (sometimes very shortly burn out) and a short lifespan.

Heat depending on watts of lights, for a 4×4 tent should have a grow light having an actual wattage range of 500-600 watts. Flowering plants require a lot of light and congregate in a single area.

PAR is the wavelengths of light within a visible range of 400-700 nano-meters (nm) which drive photosynthesis. PAR is a much used or often misused horticulture lighting. The process of photosynthesis green plants turn sunlight into carbohydrates does not use green light. 

Green leaves absorb a great deal of the light at blue and red wavelengths, though plants appear green because they reflect green light. But they have no use for such wavelengths.

Intensity of Light

Light intensity means the amount of energy arrives per unit. Measuring light intensity is the number of lumens falling on a surface, which is known as LUX. More intense lights are to be more bright.

The different growth stages of plants require different light intensity. Sometimes light intensity has benefits but disadvantages, too. 

The range of 300 to 800 lumens is required for every square foot, which is an ideal intensity, e.g. lumens for growing plants. The intensity or lumen depends on the size of the tents and what kinds of plants you are growing.
