What is the wattage [watts]?

The amount of power/energy consumed by light is measured in watts or wattage that indicates energy per unit time.

For example, A 50W light bulb uses energy equal to 50-watt-hours (W·h), or 180 kJ in one hour. A 100-watt light bulb would use an equal amount of energy within a half hours, or a 10-watt bulb for 5 hours.

The brightness is measured in LUMENS. The higher lumens means brighter light. Understanding the Lumens is the most key step to comprehend the quantity of light provided by energy-efficient CFL and LED lights as their demand is growing on the market. The FTC 2012 regulation requires the light bulb labels to emphasize Lumens instead of the Watts as the standard of measure for the brightness of light bulbs. Different models of grow light of the same watts emit different lumen of light. in this guide, it will be easier for you to compare them on the basis of the lumen.

How many Watts per Square Foot for Lighting?

It is important to understand that the number of actual watts that you need for your grow will vary depending on:

  • Plant type (high light or low light)
    • Plants such as peppers, tomatoes, etc require a higher amount of light
    • Low light plants includes leafy greens, herbs, and basil lettuce
  • Growth phase
    • Plants need a varying degree of light during different stages including seedlings, vegetative, and flowering stage.
  • The size of your canopy [The area you need to cover for plants]
    • Larger grow area needs light with more wattage.

Coverage Area by watts

First, let’s look at the footprint. Although many manufacturers mention the “core coverage” on websites/manuals, consider these figure with a grain of salt. Here are some recommendations:

Here is an overview of Light Size, for Foot Print of

  • 2′ x 2‘, a single 150-250 watt unit should be suitable for this space
  • For Foot Print of 2′ x 3′, a single 300-400 watt unit
  • 2′ x 4′,  two 150-250 watt units
  • 4′ x 4′, four 150-250 watt units, a pair of 300-400 watt units or a single 600+ unit. Read in detail about LED grow lights for 4 x 4 grow tent
  • 4′ x 6′, a pair of 600+ units or three 300-400 wattage units

Actual Wattage

First, you need to understand that all watts are not created equal (will actually a watt is a watt). The watt isn’t the same as labeled by the manufacturers on the light units. You should check the wattage a light actually uses and not the “watts on the board”.

Let’s take a light unit as an example that has 300 x 3w LED chips on its board, 300 x 3 = 900 so do I have a 900-watt LED light, right? No! The light is capable of a maximum of 900 watts if driven to its full capacity.

Operating a light to its maximum produce a lot of heat and considerably reduce the lifespan of the light unit. So to balance the fine line of reliability and performance, manufacturers design their light units to operate at a fraction of full capacity.

So that same unit with the led board of 900 wattages may have a label of “actual wattage” anything from a 380 to an 800W light. The key is to check the actual power draw of the light, not trust on the name is.

Growing Tips

LED grow lights are powerful and can get great yields when used correctly.

The recommended height of LED grow light from the top of the plants differs considerably from model to model and from brand to brand. The optimal distance from plants is influenced by many factors, including the way the lenses reflect light downwards at your plants (angle), and the individual size of each LED bulb!

Generally, You should LEDs at least 18″ above the tops of plants. Ultimately the best you can do is to contact the manufacturer and ask about their recommendation of the distance of LED grow lights from the tops of plants.

Lighting Time:

Vegetative Stage: 12-14 hrs on

Flowering Stage: 9-12 hrs on

Fruiting Stage: 7- 8 hrs on

Height above Plants:

During different stages of plants’ life cycle, they need a different amount of light. You can control the intensity by changing the height of LEDs above plants.

Seeding: 24 inches

Germination: 24 to 30 inches

Vegetative Stage: 18 to 24 inches

Flowering: 12 to 18 inches

Although LEDs run cool, some LED grow lights emit an intense amount of light that is great for yields but can burn the plants if kept too close.

Precautions, tips, and Recommendations for Growing

  • Most of Grow Lights are for indoor use only and not waterproof. Avoid keeping the lights in dripping water or anywhere with the risk of getting them wet.
  • Turn off the power when there is a lightning strike or thundering to protect the light.
  • LEDs are very intense and may cause visual color distortion, “spots” or temporary blindness. Wear sunglasses when lights are on.
  • If the fan stops spinning, turn off the light.
  • The working environment of most grow lights is -20~40℃,45%RH~90%RH.
  • Maintain a stable voltage to prevent any damage to the light fixture.
  • Don’t touch or move when the light is turned on.
  • Keeping LEDs Too Close Can Give Your Plants “Sunburn” That Looks Like a Nutrient Deficiency!
