Best LED Grow Lights for Lettuce Reviews

01. King Plus 3000 Watt Grow Light

Check Latest Price on amazon

The King Plus is a high power LED grow light by King LED. This is a 3000 Watt equivalent version powered by energy efficient dual-chip LEDs.


It has roughly 300 dual-chip 10 watt LEDs. That results in lower energy consumption than if the LED bulbs were all individually wired into the light board. It consumes roughly 500 watts of electricity. It also generates very little waste heat, though it does have fans and vertical exhaust vents to help it keep cool.

You get pretty much everything you need out of the box. You get the grow light, power cable, hanging kit and protective glasses.

This is a full spectrum grow light. It puts out light in both the red and blue spectrum. It is unusual for putting out modest amounts of ultraviolent and infrared light.


It is advertised as a 3000 watt light. It is only equal to a 2000 watt HPS light. We’d recommend it for providing light for fruiting plants in a three foot by three foot area at a height of 12 to 18 inches. It can provide supplemental red or blue light at a height of three feet, allowing you to increase the yield of a window garden or foster the growth of indoor plants that mostly rely on indoor fluorescent lights to grow.

It has a lot of red light but not quite enough blue light for seedlings. Its light spectrum often results in leggy plants, resulting in too much greenery if you want the plant to grow tall. That isn’t an issue, though, if you’re raising sprouts for your salad. This is the best led grow light for lettuce and hydroponic systems but not for anything that will be more than a foot tall.King plus led grow lights are very good for all types of plants.


  •  Energy efficient
  •  Full spectrum light


  •  Not as bright as promised
  • A little too much red light

02. Wills Brand CREE 2000 Watt Grow Light

Check Latest Price on amazon

This 2000 watt grow light is sold with a thermometer and humidity gauge as well as a hanging kit. Yet it only consumes 430 watts of power. You can choose to reduce the power consumption by turning the COBB lights off. One point in favor of this unit is that it can accept either 120 or 240 volt AC power. This unit is unusual for being safe to operate at up to 95 percent relative humidity, though it should never get wet. That makes it suitable for use above hydroponics tanks growing lettuce and fish tanks, but it should never be hit with water from your irrigation system.


This is another full spectrum grow light. It puts out infrared, red, blue, ultraviolet and white light. That allows you to see what is going on with the plants while fostering their growth. Note that very few grow lights have IR lights on them.

The grow light can cover a four foot by four foot growing area hanging 24 inches above your plants.

There are four quiet fans and a heat sink built into the grow light array. It will naturally stay cool as long as you don’t have too many lights on.


The lights are prone to burning out. And given its design, you can’t really replace them. Fortunately, it tends to be the infrared or UV lights rather than whole sections of the red and blue lights.

The COBB lights tend to burn hot. That can raise the temperature in the grow tent ten degrees unless you have a fan going in addition to those on the grow light.


  • Comes with environmental monitoring equipment
  • Energy efficient
  • Can operate in areas with high humidity


  •  Runs hot
  •  Supplemental lights tend to burn out

03.VIPARSPECTRA Full Spectrum Reflector-Series Grow Light 300W LED

  • Operates on little power, allowing you to grow indoor plants on a budget.
  • Emits a full spectrum of light, which is essential for plants to reap the full benefits of the lamp. Only the best LED grow lights for lettuce use this feature.


  • Due to its small size, it may not be ideal for more than a few heads of lettuce. This is meant for small-scale growing.
  • Some people have said the lights may burn plants, but this seems quite rare and affects only a small percentage of buyers.

05.Roleadro Brand Galaxyhydro Series 1000 Watt LED Grow Light

This 1000 watt LED grow light by Releandro is a full spectrum grow light. It doesn’t just put out red and blue light. It also generates UV and infrared light for a more natural light pattern. This means the grow light can support growing plants at all stages of development. However, it is red dominant.

This grow light will use far less power than average. It combines a high PAR value with an optical lens to maximize the light delivered to the area directly under the grow light. It relies on a connected series of 10 watt LED chips, reducing loses through the circuits, too. You can afford to grow herbs and vegetables under the hanging grow light year-round. That is why this grow light uses just 135 watts of power and matches the performance of a 1000 watt grow light.

The grow lights are designed so that you can connect them in a daisy chain, allowing you to plug up to three grow lights to each other and a single power outlet. It can work at 100 to 240 volts AC power. It generally comes with only one short electric plug and a basic hanging kit.

A side benefit of the design is the Zener electrical connections that ensure it won’t overheat. These grow lights won’t overheat your greenhouse. More importantly, the heat removal system ensures the power circuits won’t overheat, too. There is an effective heat sink system and two fans. You can then vent the little waste heat out of the greenhouse, easily maintaining an ideal, consistent temperature. The control system is straightforward but not very intelligent.

This hanging grow light can support one sun loving plant at an elevation of 18 inches or supplement natural light for window gardens at 36 to 48 inches of elevation. The maximum coverage area is 3’ x 3’. It works best when covering a 2’ x 2’ area. Any lower, and you risk sunburning the plants in the central coverage area.

The larger coverage area can help leaf growth but it doesn’t have enough blue to grow hardy stems without some natural light in addition to the LED light. That makes this the best led grow light for lettuce but not poinsettias.

The manufacturer says the grow lights can run for tens of thousands of hours. Unfortunately, it will often die after just a couple of months of continuous usage. If it still works, it will have up to a third of the lights burn out, hurting the light output of the grow light.


  • Energy efficient
  • Broad spectrum grow light
  • Won’t overheat even if running for 18 hours a day


  •  Not the best operating life

06.Phlizon Newest led grow light

This unit comes with a fully stocked hanging kit. There are multiple support wires. It also has a long power cord.This is a full spectrum grow light. It has almost as much blue light as red light. That makes it ideal for tall flowering plants.

The mix of infrared, UV and white light allows you to see what is going on and grow a variety of plants under it. The unit has a basic controller, but you can switch it from vegetation to blooming light profiles by switching a knob.

It is a powerful light. The unit consumes only 110 watts. The light output matches that of a 400 watt metal hydride grow light. The two cooling fans will prevent the light from getting too hot, too. This unit can provide the entire light needs of a 2’ x 2’ growing area at a height of two feet or 24 inches. This is the best led grow light for lettuce if you can place it at the ideal height for your plants.

No grow light is perfect. One downside of this model is that it is not FCC compliant. The grow light will generate a minor RF signal that interferes with wireless signals. Now your wi-fi, wireless controllers, and wireless internet don’t work while it is own.

There is no reflector. The manufacturer says this prevents heat buildup and eliminates the risk of sunburned plants. Yet the control board itself can suffer LED burnouts, where the LEDs actually melt. If this happens, shut it off immediately before you get a cascading failure. In a worst case scenario, it can catch fire.


  •  Great hanging hardware
  • Switch growing profiles at the flip of a switch


  •  Generates radio frequency interference or RFI
  •  Can suffer overheating in the circuit board, a potential fire hazard

How to grow lettuce under led grow light

Leafy green vegetables are among the easiest to grow, especially if you’re raising them in a greenhouse or hydroponics system. This is why lettuce along with spinach and herbs are the darlings of vertical farms. However, average people can grow lettuce and similar leafy crops indoors with the same technology. Let’s learn how to grow lettuce under LED grow light systems.

Choose the Right Growing Caddy

You can raise lettuce and other leafy greens in a window box full of soil, but that’s not the most efficient method for doing so. One option is raising them in an aeroponics system; this minimizes water use and space but requires complicated pump systems and added nutrients. Another option is a hydroponics system. This setup could use wastewater from an aquarium as well as nutrient solutions you add to the water.

Get the Right Lights

If you want to raise lettuce under led grow light systems instead of natural light, get the right type of lights. This will take the form of predominantly red LED grow lights. Leafy plants really don’t need the blue light to foster stem growth. And broad-spectrum white lights don’t provide enough red light to maximize leaf growth, though that is exactly what you want with leafy greens.

Choose the Right Seeds

There are plant varieties that do better when grown indoors than others. Choose a low-maintenance strain. Quick-growing varieties that are easy to harvest are popular for indoor growers since their goal is usually to get as much food as possible as quickly as possible. Butter lettuce, leaf lettuce, and romaine lettuce make this list. You could mix things up by included spinach, kale, bok choy, and arugula. Then you’re growing your own salad mix.

Set Up Your System

Once you have the planters and lights, you can set it up and then plant your seeds. In the case of some starter hydroponics and aeroponics systems, it may have seeds in pre-made pods you’d just drop in the tray. Then give it water and light.

There are several advantages to raising leaf crops like lettuce and spinach. You can eat baby greens soon after they’ve sprouted, whereas there’s nothing from a tomato plant until it flowers and then fruits. Once the plant is growing leaves, it will continue to produce leaves as long as you keep it alive. Depending on the lettuce strain, you may be able to harvest leaves for weeks.

Take Care of Your Plants

You should know how much light the plants need per day for maximum growth. No matter what leafy green you’re growing, don’t have more than 16 hours of light. Plants like people need rest.

If you’re providing supplemental light for plants that also receive natural light, you may only need a few hours of artificial light. Try not to give them too much blue light or harsh light from metal hydride lamps, because this can cause the lettuce to flower. This turns the leaves bitter and eventually causes it to stop producing leaves for consumption. Too much light can also cause the lettuce to produce anthocyanin; this turns the lettuce red.

Plants thrive when the conditions mimic their ideal natural conditions. This means ensuring that the grow tent doesn’t become too humid, since that can foster mold growth. Make sure the temperature is kept relatively constant and in the ideal range for the plants.

One irony of growing plants in hydroponics systems is that they may grow too well. This is why you’ll need to trim the roots or move them so that the growing roots don’t block the water channels. And harvest when the leaves are ready.


If you want to buy best led grow light for your lettuce in 2022 you should choose the above lights because these lights are cheap and long lasting.
