On top of the best budget LED grow lights is this model by ViparSpectra. The company has taken great strides in the recent years, so much so that for many customers, ViperSpectra is synonymous with LED lights. The Reflector-Series is probably one of the most powerful LED grow lights on this list as it has a 600 watts output. It is essentially an assemblage of 120 5-watt LED chips. The average lifespan is superior to most: at 100,000 hours. Besides, the company also provides three years of warranty just in case things do go wrong.

These are extremely powerful and potent LED lamps: what the company has done to keep them cools is that they have added aluminum heat sinks and cooling fans. Upon testing, we found that it is capable of covering an area of more than the advertised 3 x 3 feet while suspended at 24 inches. In our experience, it is more than capable of covering an area of around 4 x 4 feet at the same height.

A big reason why this counts as one of the top LED grow lamps of 2018 is that it has veg/bloom switches: this dual-power system is capable of modifying and optimizing the emitted light so as to allow the plants to flower or fruit. In both cases, this lamp has proven to be extremely capable.

  • Wattage-600 watts
  • Full Spectrum Coverage: Yes
  • Coverage– 3 x 3 feet and more
  • Life Span: 100,000 hours
  • Power Draw: 276 watts

If you are looking for the best budget LED grow lights of 2018, look no further. The Galaxyhydro Series has, in many ways, revolutionized the way the general public looks at LED grow lamps for the simple reason that it was one of the first companies to get into this business. This 300-Watt LED grow light is easily a star as far as cheap LED grow lights 2018 are concerned.

Galaxyhydro has incorporated both UV and IR lights in their setup. The device consists of 100 3-watt Epiled LED chips and is not designed to cover the entire spectrum. It does, however, cover the optimal 9-band spectrum which plants use to grow, including the 430nm, 450nm to 470nm, as well as the 620nm-630nm, and 740nm spectrums, besides white light and the aforementioned UV and IR spectrums.

All these portions covered means that the plants will grow both quickly and will be stronger. Being a cheap LED grow lamp, it naturally covers a slightly lesser space. This budget pick does come with a two-year warranty and a hanging kit. However, it lacks a power switch and the lights cannot be adjusted for different stages of plant growth. The device can, however, be hooked up to a timer so that your plants grow as you desire. The timer will provide adequate periods of light and rest for the saplings too.

  • Wattage: 300 Watts

Being LED full spectrum grow lights, they can be rather useful when the plant is blooming. The 90 3-watt LEDs are arranged in 6 neat groups and cover all the 12 important spectrums. The UV and IR light inclusion mean that in case you are ultimately planning to transplant the sapling outside, you can do so with ease.

To help cool the LED lamp and to keep things going, there are four fans and heat sinks. When it comes to the Kind K3 L300 grow lights review, they are also pretty good choices for hydroponic and other indoor lighting purposes. They can cover an area as wide as 5 x 5 feet across (as determined in our tests) although the advertised limits are slightly lower.

Onboard is a special and proprietary feature Kind calls “Secondary Optical Lens.”  This ensures that the lowest and the most remote parts of the plants get their own equal share of the light. Since the entire plant can photosynthesize, this naturally makes a lot of sense. Take the 3-year warranty period offered and this is easily one of the best indoor LED grow lamps 2018.

  Get it now on Amazon.com

This LED grow light is composed of 60 5-watt LEDs. Ideal for purchase as a cheap LED grow light, this model is probably the easiest to use as well. Covering the entire light spectrum recommended for indoor gardening, this model also has 5,000 lumens of brightness overall and claims to cover 3.9 square meters or an area equal to 6,200 square inches. This claim does seem to be slightly inflated; we guess that an area of 3 x 3 feet is more realistic.

The first thing that grabbed our attention was that this model comes with a stainless steel hanging kit and with two cooling fans. This 300-Watt model is not Daisy-chainable; it does have a 600-watt elder sibling which lends itself to Daisy-chaining admirably. Also, in the course of the Roleadro 300-watt LED grow light review, one thing must be mentioned: that it comes with a handy two-year warranty period.

Being a budget LED grow light, it is to be expected that certain features will be missing. On this model, there are no switches to control the LEDs or to control the power supply.

  • Wattage: 3oo watts

Verdict

Overall, this model is a great value-for-money LED grow lamp and can be easily suspended thanks to the lightweight steel chain. It has a very distinctive look to it and comes with two years of warranty. The fact that it covers the entire spectrum while still posing a lower price tag is in itself its greatest USP.

#5 HIGROW Optical Lens-Series

This is the brightest LED grow light on this list with an amazing 1000 watts. Together with the fact that it offers extremely decent full spectrum coverage, this is one of those rare finds that grows your plants- and weed, if you are into that sort of thing- like a boss!

HIGROW has ensured that this model covers the 12-band full spectrum, ranging from 380-760nm, and also including UV and IR.

  Get it now on Amazon.com

In case you are looking for the best 1000 watt LED grow lights, you might want to go for this CrxSunny model. This is also our pick for the best LED grow light under $150. The one thing that we like the best about this model is that even in its comparatively small size, it is still able to generate 1000 watts of brightness.

The design features and technical details of this item are significantly different. For example, unlike the other models, this one has five integrated 200-watt LEDs. It is also packed with a “COB” which stands for “chip on board,” which, many users have said and is true in our experience as well, captures and emits the truest form of sunlight so essential for photosynthesis.

This is one of the top LED grow lights of 2018 for other reasons too. It is minimalistic in design and only has 5 LEDs as we said. The hanging kit is included as well while the device itself can cover up to an area of 3.5×3.5 feet while perched at the height of 24 inches. It is thus ideal for small indoor gardens and also greenhouses. Since this is a 1000 watt model, there is bound to be some heat generated. The company has strived to stave this off with fans and a heatsink. The three-year warranty does not hurt one bit.

  • Wattage: 1000 watts
  • Full Spectrum Coverage: Yes
  • Coverage: 3 x 3 feet

Verdict

Overall, the Crxsunny COB LED is definitely one of the best budget LED Grow Lights. It also has a certain design which makes it pretty catchy. The design factor has been copied many times but has never replicated exactly. Note that in case you are using it, you should keep it in a well-ventilated area. It does tend to get very hot.

Best LED Grow Lights of 2018: Buying Guide

A buying guide is a list of criteria that must be fulfilled in order to make the item ideal for purchase. Before you go all-out splurging on anything, in this case, an LED Grow Light, there are certain conditions that need to be met. This is why the buying guide for best LED grow lights 2018 is required. Since every person’s requirements are different, every purchase decision will be different. Do ensure that the following basic requirements are met, however.

Wattage: The wattage of a given LED grow lamp is the maximum energy generated at the maximum capacity. The higher the wattage of the device, the greater the illumination of the device. You should choose a LED grow lamp with a significantly high wattage: at least 400 watts are required. Do note that the higher wattage has two significant drawbacks:

  • It gets too hot too fast unless the fans and the heatsink work really well
  • The higher the wattage, the more the power consumption.

In short, you must strike a balance between the power and the economy of the device.

Coverage: Like all the points on this list, this one is pretty self-explanatory. The coverage is the amount of area the LED light reaches when at max capacity. A greater coverage generally means a bigger device and a bigger kit overall. The greater the coverage area, the better the device is. The coverage depends on the size of the indoor garden.

Full Spectrum Coverage: This is a term that you will find multiple times here. Simply put, the full spectrum LED grow lights actually mimic the sun’s natural light spectrum and intensity. The more the spectrum coverage, the faster a plant will grow; irrespective of which stage of growth it currently is at. As you have seen, most of the best LED grow lights of 2018 have this feature enabled.

Lifespan: The lifespan of the LED is measured in hours. As you have seen, most of the LEDs on the list have an average lifespan between 50,000 and 100,000 hours. Try to buy something in that range.

Replacements: Replacements here do not mean replacements of the LEDs themselves; rather, we are talking about the devices/light sources which they are designed to replace. LEDs can replace namely High-Pressure Sodium (HPS) lamps, Metal Halide (MH) as well as High-Intensity Discharge (HID) lights.

Power Draw: The name explains itself. The top LED grow lamps must have adequately low power draw and use so that the actual power consumption never exceeds the rated power output. The power draw must be kept in mind to maintain the economy and power usage/wastage.

Wrap up

Before you buy one (or two) of these best LED grow lamps of 2018, do remember that not everyone needs a 1000 watt device. Smaller ones can often be equally effective.
