What makes the best LED grow light?
The best LED grow lights have a few things in common - a uniform spectrum, efficiency, high-power, and reliability/durability.
Spectrum/uniformity
The best LED grow lights have a uniform spectrum, so if you have 4 plants under your light, they all get the same spectrum.
We already touched on spectrum a bit, but its important to reiterate that the best spectrum consists of not just red and blue light, but also infrared (IR) and Ultraviolet (UV).
Full spectrum LEDs allow you to grow from seed to harvest with the same light, as opposed to having to replace bulbs or use different grow lights for veg/flower.
Power
The more light your LED actually gives off, the bigger yields you’ll get (for the most part). So, the best LED grow lights need to be incredibly powerful.
Efficiency
In general, LED grow lights are very efficient. But, the best LED grow lights tend to also be the most efficient. Operating at a high level, producing high power, and maintaining a low cost to run is very important.
Reliability/Durability
Given the cost of LED grow lights, they need to be seen as an investment. Obviously, your investment needs to last you a long time for it to show a return.
Therefore, the best LED grow lights are reliable and durable, standing the test of time.

Types of LED grow lights
LED grow lights are available in different forms, so let’s look at the pros and cons of each so you can find the right LED light for you:
LED Grow Light Panels
Panels are the most common type of LED grow light and most of our list will consist of LED panels.
They include heatsinks for removing heat, a driver (think of it as a ballast), and often come with a warranty.
When you think of LED grow lights, you are more than likely thinking of an LED panel, as these are the only type of LED really suitable for full state growth.
Pros:
Full spectrum with switches for both the vegetative and flowering stage – can be combined
Comes ready to plug right into a standard house outlet
Incredibly long lifespan – the bulbs typically last for decades.
Cons:
Most expensive type of LED grow light
LED Grow Light Bars
Many growers add LED bars as an easy way to expand their lighting footprint or change up their light spectrum. LED Bars are a single row of diodes that come in different spectrums.
You typically wouldn’t use an LED bar to grow a plant from seed to harvest. Instead, think of these as supplemental lighting to a main light source (maybe HID).
Pros:
Can replace T5 fixtures for increased PAR and less energy consumption
Some units come plug-and-play and can work with a standard 120V house outlet
Cons:
Usually only one spectrum with no switching options
Can usually only be used for supplementing, and multiple bars will need to be purchased if using as sole light type
LED Grow Light Bulbs
An LED grow light bulb is exactly what it sounds like – a single LED bulb. Similar to LED bars, you wouldn’t usually use one of these to grow plants through flower.
But, they can be a great way to grow small leafy greens or start plants with a full spectrum. You can quickly replace all old CFL bulbs with LED bulbs, which will give you all the added benefits of LED grow lights.
Pros:
Work in a standard light socket
Great for mixing and matching to create your preferred spectrum
Cons:
Multiple bulbs required
A reflective hood may be required
