Factors to consider when buying the best LED light for 4×4 grow tent


When buying the best LED light for 4×4 grow tent, you need to consider the power. LED lights should not be chosen by power, but the efficiency of different models is different, and glow with the same power can vary significantly in brightness.

The LED lights that replace a regular 60 W pear bulb can have a capacity of 6 to 10 W, and the lights that replace a 40 W “candle” can have a power of 4 to 7 watts.

Light flow

The LED light brightness it gives, is defined by a luminous flux parameter, which is measured in lumens (Lm).

For the ordinary light, you can roughly estimate the required luminous flux by multiplying the conventional incandescent light power by 10: 60 W corresponds to l00 Lm, 40 W to 400 Lm, 100 W to 1000 Lm, and more. 

So, if you are looking to buy an LED replacement for a 60W incandescent bulb, look for bulbs with at least 600 Lumens. Unfortunately, many manufacturers overestimate the value of the luminous flux. 

It can be twice as low as stated and even more. The results of independent testing can only determine the actual values ​​of the luminous flux.

Colorful temperature

LED lights with a 2500 to 3500K color temperature to have a warm glow. They should be chosen for an installation in recreation rooms. It is believed that they have a positive effect on human comfort. The models with soft yellow light are almost identical to that emitted by incandescent bulbs.

LED lights with a color temperature of 4000 to 5000K to have the so-called daylight. They are neutral and can be located in work areas. It can be offices and a kitchen, bathroom, etc. The brightest lights with a color temperature of more than 5500K have a cold light.

Their glow is very white with a bluish tint. A person is very sensitive to such light and receives a feeling of wakefulness in its presence. If you stay in a room with such lamps for a long time, you may experience a sense of fatigue over time.


When buying the best LED light for 4×4 grow tent, you need to consider the voltage. LED lights use different drivers (electronic boards installed in the lamp base). 

Many models use stabilized drivers. The brightness of such LED lights does not change when the mains voltage fluctuates over very large limits. 

Some shine equally brightly when the mains voltage drops from 230 to 70 volts. Unfortunately, manufacturers often do not indicate the actual voltage range. 220-240 V or 230 V may be written on the lamp’s packaging, but in reality, the light burns at a much lower voltage.

Twelve-volt lights are available with E14, E27, GU5.3, and G4 bases and can operate on DC and AC voltages. 

Most microlights with a G4 base and some spot lamps with a GU5.3 base, when operated on AC voltage, have a very high light pulsation, which is harmful to the eyes and well-being in general. To avoid pulsing such LED lights, you will have to replace the transformers with DC power supplies.

Dimmer support

Most LED lights cannot be dimmed, but unique dimmable LED lights are available that support dimming. These models work with most conventional incandescent dimmers, but the minimum dimming level can be pretty high (about 20%). 

For the lights to be dimmed to almost zero brightness, it is necessary to use special dimmers for LED lights.

Ripple of light

The pulsation of light leads to eye fatigue and a general deterioration in well-being; therefore, it is imperative to use only those lights that do not have visible pulsation. According to SNIP for various types of premises, light pulsation is normalized in 5-20%.

A pulsation of up to 35% is imperceptible to a person. Other LED lights may have a low pulsation level, but this is not indicated in the light parameters. 

The presence of pulsation can be checked using the pencil test or by looking at the lamp’s light through the smartphone’s camera. If there is pulsation, stripes will be visible on the screen.

Life time

Manufacturers indicate light life from 10,000 to 50,000 hours. No one knows how long a LED light will last in reality because technologies are improving very quickly, and all service lives are calculated theoretically. 

It is recommended to pay attention not to the specified service life but to the warranty period, during which you can exchange a light that has failed.

Beam Angle

Another thing you need to consider when buying the best LED light for 4×4 grow tent is the beam angle. You need to know the shape or angle of the light beam that comes out of the LED fixture.

The shape is described as a beam angle. Typically, the angle (light distribution) can be narrow or wide. If you have a narrow beam angle, you will concentrate the light into a smaller area, increasing the amount of light that shines.

If you have a wide beam angle, the light will be more diffuse. You will illuminate a large area, but you can scatter a light over a wider area, reducing the light on a surface.

Also, consider the cone-shaped light distribution of the LED lights. As the space from the light source increases, the dispersion also increases. This means that if you have high ceilings, you will need to choose an LED light with a narrow beam angle so that the light can reach the lighting surface.


Most of the LED lights for 4×4 grow tents come with a 1 to 5-year warranty. Stores must replace lights under warranty within this period if they fail. In addition, under consumer protection law, you can return the lights to the store within 14 days of purchase, and you will get a new one.
