400 Watt LED Grow Lights

When you're picking a 400W grow light for your indoor garden, you might think that an LED light is the best choice. And you're right - LED lights are pretty awesome. They can help you grow a ton of high-quality plants when you use them correctly.

How many plants can a 400w LED light grow

A 400w LED light can effectively grow between 1-16 cannabis plants, depending on the growing method, desired plant size, and length of the vegetative period. Take the CT-480 LED grow light, for example. You can use it to grow 3-5 plants in a 4x4 grow tent. And get this - some growers have used the CT-480 and pulled in a whopping 1.5kg of buds at harvest time!

How much does it cost to run a 400 watt LED grow light?

The amount of electricity consumed by a light fixture = Light fixture power (watts) * Light fixture operating time (hours) / 1000 When an 400-watt LED plant light is working at full load (i.e., 100% dimming) for 10 hours: 400 * 10 / 1000 = 4 kWh, which is equivalent to 4 units of electricity.

If the light fixture is not dimmed to 100% when working, calculate the actual power it is dimmed to, then multiply it by the working time, and finally divide by 1000 to obtain the electricity consumed.

What is the footprint coverage a 400 watt LED grow light?

The footprint coverage of a 400-watt cannabis LED grow light can vary depending on the specific light fixture and the height at which it is hung above the plants. However, in general, a 400-watt LED grow light can effectively cover the following areas:

Vegetative stage: When hung at a height of 24-36 inches, a 400-watt LED can cover an area of approximately 3x3 feet to 4x4 feet.

Flowering stage: During the flowering stage, when the light is hung at a height of 18-24 inches, a 400-watt LED can cover an area of roughly 2.5x2.5 feet to 3.5x3.5 feet.
