Our Reviews

King LED Full Spectrum Grow Lights

Another Chinese based company, King LED have been going since 2012, and have made considerable inroads into the LED market just like Viparspectra and Bestva. They have a pretty extensive range of full-spectrum LED lights, and most are top-rated, averaging four-star plus reviews across most models. To be honest, these three brands are pretty interchangeable and offer the indoor grower a good selection. They’re known for producing some basic no-frills LED full spectrum panels, at affordable prices that can be found on most big online retailers, to see their higher spec LED you’d have to pop over and take a quick look at their website.

Low cost and thousands of four-star plus reviews are the first things that will stand out to most, standard build quality and features are to be expected from King LED. Most models come with double chips, efficient PAR/LUMEN output, and are full-spectrum, mimicking good conditions for veg and flower growth.

King LED just like other Chinese firms, mainly suffers due to build quality, red and blue light disparity, shortened product life span and blown bulbs. King LED try to answer any customer queries as fast as possible, but with being based in China again has its limitations.

King LED is a company that offers various LED products at reasonable prices, they’re sold through most popular online retailers and sit comfortably within that mid-range quality bracket. Of course, If you’re one of the unlucky ones that experience problems, you’ll probably never buy from any Chinese branded LED companies ever again, but with a high volume of users experiencing no problems whatsoever, King LED is seen by many as another viable option.

Some of the most searched for and popular models from King LED lights are:

  • King Plus 3000W Double Chips LED Grow Light Full Spectrum
  • King Plus 2000W Double Chips LED Grow Light Full Spectrum
  • King Plus 1500W Double Chips LED Grow Light Full Spectrum
  • King Plus 1000W Double Chips LED Grow Light Full Spectrum


  • Duel-chip technology
  • Efficient PAR/LUMEN output
  • Hundreds of 4 star reviews
  • Low cost
  • Efficient cooling system


  • Red & Blue light disparity
  • Short lifespan
  • Build quality
  • Blown bulbs

Mars Hydro Full Spectrum LED Grow Lights

Established in 2009, Mars Hydro is another Chinese branded company, that has gone from strength to strength, eventually becoming the trusted well-known brand they are today. They sell everything from grow accessories up to grow tents, all at affordable prices while producing high-end quality products. They have warehouses across the globe and ship to most countries. Averaging four-star plus reviews from thousands of reviewers across the whole of their product ranges, you know you’re in safe hands when opting for anything from Marshydro.

Compared to the other brands, Mars Hydro is on another level. They offer the grower a very extensive range of LED lights, all the while never slipping in terms of build quality, four-plus star reviews are very common for most of Mars Hydro products, with the majority awarded five-star ratings consistently.

Prices vary but generally start off around the sixty dollar range, which isn’t bad compared to build quality. With warehouses based around the globe, shipping is relatively quick, and any problems you may encounter are generally solved fairly quickly, they also offer a three-year warranty on most products.

If you’re one of the unlucky ones that experience problems with a Mars Hydro product, you’re usually covered by a three-year warranty, but that’s only if you can get them to honor it, a small minority of consumers have reported problems getting Marshydro to follow through on their warranty claim, this can obviously be very frustrating, and as a consequence trust can be lost with the brand itself.

As well as the above, problems have been reported of certain products prematurely failing, bulbs burning out long before their time, and low yields produced due to insufficient power. Saying that this is a very small minority, and no doubt some problems encountered can be put down to the grower, their set-up or products being damaged in the delivery process.


  • Well-known Established Brand
  • Excellent build quality
  • Ships to most countries
  • Different models to suit your budget
  • Upgraded chips, fans & power supply
  • Flexible U-connector, meaning multiple lights can be connected
  • 3-years warranty with a customer support base in the US


  • Premature failure of some models
  • Blown bulbs
  • Broken & faulty parts upon delivery
  • Difficulties reported with repairs & honouring warranties

Viparspectra Full Spectrum LED Grow Lights

Viparspectra is one of the more popular reviewed brands in the LED market that are commonly used for indoor grow set-ups, but being popular doesn’t always mean you’re the best.

When searching online for the best full spectrum led panels or led in general. Viparspectra is often one of the first you’ll come across, whether that’s from searching the big online retailers or forums, Viparspectra will be one of the first mentioned for good or bad.

The Viparspectra range is generally a trusted well-known brand and offers growers a varied enough selection of different products compared to their competitors. They’re of mid-range build quality and offer you some good specifications.

Prices are fairly reasonable, often starting from the eighty dollar range but can reach up to just under the five hundred dollar mark, so be sure you’ve done your research before buying.

Certain models also offer UL certification, excellent par output and options to switch from full spectrum.

If any problems do appear, Viparspectra is generally quite good and will try and rectify as quickly as possible once it’s been confirmed you’re a verified buyer.

This is a Chinese brand, which can sometimes be off-putting to some. Because of this, shipping may generally take longer.

As for complaints about the products themselves, generally the most common come from lights underperforming, lights becoming too hot and burning the crop, and the product developing faults fairly quickly or not working at all. (This could be due to 3rd party sellers and the type of grow set-up) fans can sometimes be noisy, as well as plants taking longer to flower compared to traditionally used lighting.

Viparspectra is a well known and established brand who have consistently rated four stars and above, they produce affordable good quality products and offer various models to satisfy most growers needs.

Some of the most popular LED models Viparspectra do are:

  • Viparspectra PAR series Grow Light
  • Viparspectra Timer Controlled series
  • Viparspectra UL Certified Reflector Series


  • Trusted, well-known brand that offers cultivators a varied selection of different products compared to their competitors
  • They’re of mid- high end build quality and offer some good specifications for their lower priced models
  • Certain models also offer UL certification, excellent par output and options to switch from full spectrum
  • Excellent customer service
  • Full spectrum lighting which provides plants with all they need, in all stages of growth, from veg to flower


  • This is a Chinese brand, which can sometimes be off-putting to some. Because of this, shipping may generally take longer
  • Lights sometimes under performing
  • Some reports of fans being overly noisy
  • Overheating in some models

Bestva Full Spectrum LED Grow Lights

Bestva is another well-reviewed Chinese manufacturer of LED grow lights, consistently receiving four plus star reviews. They fit nicely into the mid-range LED category, alongside it’s fellow Chinese LED company Viparspectra, they offer a varied selection of products, but not as many as some of their competitors.

Bestva offers cultivators another option in the increasingly crowded LED grow light market, they’re not producing top of the range equipment or anything revolutionary in terms of design or specifications but can be thought of a close competitor to Viparspectra.

In terms of design and functionality, they’re very very similar, with hundreds of four star plus reviews most indoor growers are satisfied with the end product.

As standard, they offer duel chip technology with high par output per watt, two fans that are generally quiet on the ear with ventilation holes integrated into the glass.

Again, cons of the Bestva brand come in the form of products failing completely in short time frames, overheating, missing or defective parts as well as coloration of the bulbs favoring one color.

Bestva will generally try and rectify any faults with the product as quickly as they can, but again being based in China has it’s limitations, paying for returns and long waits being the most common that buyers of Bestva products have to face.

Bestva offers another choice in the mid-range LED market, prices are very reasonable for most models starting just under the ninety dollar range, although they’re not the best as Viparspectra are slightly cheaper. As both brands are very interchangeable and are consistently rated four and above stars, you can do much worse than go for either.

Some of the most popular models:

  • 1500W LED Grow Light Full Spectrum Grow Lamp with IR&UV
  • 1200W LED Grow Light Full Spectrum Grow Lamp with IR&UV
  • 1000W LED Grow Light Full Spectrum Dual-Chip Growing Lamp
  • Bestva DC Series


  • Duel-chip technology
  • Quiet fan system
  • Strategically placed holes in the aluminum for heat convection
  • Most models come with a 3 years warranty


  • Reports of short lifespans with some models
  • Overheating problems
  • Color disparity

Platinum LED Full Spectrum Grow Lights

Platinum Grow Lights, are a well known established company that has been in the LED market for a few years now. They offer a wider selection of lights than most of their competitors and are consistently rated four and above stars on their products.

Based in the USA and sold through most well-known retailers, Platinum grow lights have been producing reasonably good products for a very long time and know their business very well. They’re not the best quality you can find or the best brand, but they offer another option in the mid-range LED market.

Based in the USA, and offering 5-year warranties on most products and models, Platinum LED lights offer some of the highest PAR/LUMEN per watt compared to their competitors, with a good quality 12-band full spectrum from UV to IR.

Incorporated into most models is a user-friendly switch enabling the grower to go from veg to flower with relative ease, two high speed whisper quiet fans and an aluminum heat sink as standard. To further penetrate the crops canopy, Platinum has included 90-degree secondary focusing lenses.

Platinum Grow Lights are generally more expensive than most others in their range bracket, which isn’t ideal and some common complaints of the brand are of panels not fully working, blown bulbs and a shortened lifespan of the panels in general. Flowering is often described as less dense, but this could be put down to the individual growers’ technique, and set-up.

Platinum Grow Lights have some good overall features with the added bonus of being based in the USA, but as with most brands in this range, offer nothing that is really individual or innovative to tell them apart from the rest. They offer a good beginner standard, with higher prices.

Some of the highest-rated and most popular models are:

  • Advanced Platinum Series P300 300W 12-band LED Grow Light
  • Advanced Platinum Series P600 600W 12-band LED Grow Light
  • Advanced Platinum Series P450 450W 12-band LED Grow Light

  • 12-band full spectrum


  • Blown bulbs
  • Faulty/defective models upon delivery
  • Short lifespan
  • Flowering reported as less dense
  • Higher priced than other competitors

LED: What Is It?

LED or (Light-emitting Diodes) is a form of lighting that comes in various colors depending on their intended use.

Initially because of the high cost compared to the end product, LED lighting was not a commonly used system for indoor growing.

But with the cost of LED grow lights reducing significantly over recent years and the technology advancing due to extensive research, LED has now become much more accessible to your average indoor cultivator.

LED lighting comes in a multitude of colors that have varying effects depending on which color or combination of colors are used.

Researches now know LED lighting effects both photosynthesis and morphology.

Red, far red, green and blue LED lights are known to affect plant growth, root formation, and flowering. Whereas white full spectrum offer plants a balanced recipe for all their needs.


After looking at the pros and cons of some of the best full spectrum LED grow lights that we’ve featured in today’s review, our top pick is the Mars Hydro LED grow light range.
