Top 25 LED grow lights for in 2018 for your budget - Review and guide
What are the best LED grow lights on the market in 2018? The top LEDs for indoor plants depend on how much you are willing to spend on an LED grow light and the features you want, among other several other important factors. The best least expensive LED grow light will not be the same as the best top-of-the-line LED grow light. Therefore, we've compiled a list of the best full-cycle LED grow lights under $250, $500, $1000, $1500, and $2000.
LED technology and the market demand for certain LED grow lights can evolve at a rapid pace. So, doing your research for the best LED grow lights will ensure the light you buy this year—in 2018—will still be a top fixture next year—in 2018.
You might be wondering: why spend a lot more on an LED grow light when you can get one for a lot less? The less expensive fixtures generally cover a small footprint and/or are of lesser quality. In addition, the difference between a $250 grow light and a $2000 LED grow light comes down to several other factors that need to be considered before making a purchase:
- Wattage draw
- Is it a small fixture that draws fewer watts or a large fixture that uses more power?
- ...More power is generally associated with a more expensive light.
- Diode brand and bin
- Does the unit use industry-leading, top-bin LEDs?
- ...Top-bin, higher quality diodes will be more expensive.
- Secondary lenses
- Adding secondary optics increases light intensity and may add an additional cost to the fixture.
- ...Do you need secondary optics for your grow space?
- Secondary components
- Are the heatsinks large?
- Does the unit use efficient, top brand drivers?
- Are the fans rated for 50,000 hours or more?
- ...If yes, this will increase the price of the fixture.
- Photosynthetic Photon Flux (PPF)
- Does the fixture emit a lot of light?
- ...More light = a larger investment.
- PAR efficiency
- Are the diodes and the fixture efficient (high ratio of light per joule of energy)?
- Generally above 1.5 umol/j is considered very good.
- The top fixtures are currently rated at about 2.3 umol/j.
- ...Higher efficiency = more expensive.
- Coverage area
- Does the fixture cover a 2x2, 3x3, or 4x4 or more?
- ...Larger fixtures that cover more area are more expensive.
- Advanced features
- Do you want dimmability, spectrum control, timing, scheduling control?
- ...These features may increase the price of the fixture dramatically.
- A longer warranty will likely increase the price of the fixture.
Using the factors above and 5 different price ranges, we've compiled the ultimate guide of the top 25 LED grow lights in 2018.

Johnson Grow Lights CX-1L
The Johnson Grow Lights CX-1L is perfect for vegging in a 2x2 area or flowering in a 1.25x1.25 area. The small fixture measures 7" x 7" and uses a single Top-Bin Citizen CLU048 3000K COB LED. The full spectrum is heavy in red while providing enough blue light for tight internodal spacing and a lot of green light to increase photosynthesis rates in leaves and below the top of the canopy. The unit only draws 60W but will replace a 100W HPS.
The CX-1L is fitted with a large secondary lens which helps to increase intensity and penetration. A single cooling fan helps draw cool air over the heatsink to assist in preserving the longevity and efficiency of the LED.
Growers wanting to install several of these units can daisy chain up to 10 CX-1L's together.
This fixture is perfect for growing up many seedlings, several clones, vegging a couple plants, or flowering a single plant. At $149.00 and a 3-year warranty, you can't go wrong.
Mars Hydro Reflector 96
The Mars Hydro Reflector series has been a top-seller in the LED grow light market for many years. The fixture provides a great balance between price and intensity. There are 96 5-watt Epistar diodes on the Reflector 96 grow light. The diodes are surrounded by small reflectors to direct the light to your plants. The diodes, with the driver and fans, only draw 205W at the wall while covering about a 2x3 area for veg and a slightly smaller area for flower. The unit is designed to replace a 250W HID grow light.
Growers can switch between grow and bloom mode with a flip of two switches. Veg mode is heavy in the blues, while the flower mode activates the reds, needed for optimal flowering. The Reflector 96 measures 23" x 10".
Like most LED grow lights on the market, this light has a flexible driver and is rated at 85-265V. Furthermore, depending on your country, a North American, European, or Australian power cord/plug is included with the fixture. 2 year warranty.
Mars Hydro Mars Pro II Epistar 80
The Mars Pro II series is Mars Hydros newest series and features the highest quality build and best reflector design.
The Mars Pro II Epistar 80 is ideal for vegging a 30" x 30" area (6.25 sq ft) or flowering an 18" x 18" area (2.25 sq ft). There are 16 modules on the front of the unit. Each module contains 5 different LEDs - typically 3 reds, a blue, and a white (to round out the spectrum and increase intensity and penetration). The reflector cup surrounding the diodes assists in directing the light downward instead of scattering the light to the sides.
As with the Mars Reflector Series, this unit (and series) features grow and bloom switches to help you save energy during veg. The unit only draws 81W with the grow switch on and 170W with both switches activated. The Epistar 80 only measures 11.4" x 11.4" and is ideal for smaller grows and tight spaces.
