Kind LED Review

LED lights can really make or break your growing space, which I think any grower already knows. There are a lot of variables you have to consider when choosing and installing your lighting system: the reach, the color spectrum of the lights, the wattage… the list is pretty huge.

On my hunt for the perfect LED lights for my grow room, I came across the range from Kind LED lighting.

Kind currently stocks three lines of lights:


The bar lights

  • These lights are the cheapest available on their site, and this is largely because of their more limited range on the color spectrum, and their lower wattage than some other options available on the website.
  • However, they’re a fairly good entry point for this brand

The K3 Series

  • The mid-range point in Kind’s range of products. The K3 series offers more control and versatility to the customer
  • Every item in the K3 series is full-spectrum, making them a far more versatile option compared to the bar lights

The K5 Series

  • The most expensive range available on Kind’s site, the K5 series is also their most popular due to the impressive and unique features
  • This series carries more customization, due to the fact that they’re able to connect to the WiFi
  • This means you can control the spectrum of lights remotely, as well as set up a day/night cycle in your grow room from any connected device

“I don’t know about you, but problems I’ve had with grow lights in the past are like this…”

Even while using LED lights, there can be a number of problems that you face. Some LED lights just aren’t powerful enough to deliver the necessary benefits to your plants.

When you’re investing in the health of your plants, spending time, money, and resources to perfect your grow room or grow tent, you need the best quality lights.

Poor quality lighting can be seriously detrimental to your plant’s health. Not only are you more likely to experience burnouts and breakages, but lower quality grow lighting is more likely to have lower wattage.

You need lights that are strong enough to nurture your plants. A weak LED lamp is just as bad as a good-wattage light that is too far from your plants because the result will be the same.

Plants that aren’t getting the light they need will automatically seek out a good light source, causing them to grow and stretch. Plants that grow too much and stretch out too far can become weak or top-heavy.

This can lead to breakages and poor-quality plants.

So, is there a solution?

Yes! I took to the internet to look for some high-quality brands that specialized in making LED lights to best suit my needs. I shopped around a little and came across the Kind LED lights’ website.

They have a range of different designs, from their bar lights to their innovative WiFi series, enough to suit a grower of any level.

So, what’s so special about the Kind LED Lighting?

When you go to Kind’s website, you’ll see a range of three different lights available for non-commercial use. They have the bar lights, their K5 WiFi Series, and they have the K3 series.

This wide range alone is impressive, as it allows customers to choose a light that best suits them.

We’ll start with the Bar Light

Kind LED 75w Double Sided X Series XD75 4ft. Indoor LED Grow Light Bar for Plants and Flowers (Flowering Stage)

Two makes of the bar light are available – the X40/X80 and the more expensive XD75/XD150. The X40 and X80 only carry a max wattage of 40x and 80w, respectively, explaining their lower price point (they start at $170).

The XD75/XD150 is the superior range in terms of wattage – with up to 150w, for those who want an extra kick, it may well be worth the higher price point. These start at $350.

One thing you should note with both of the ranges of bar lights is that they are more restricted than the other models available on Kind’s website. You can only buy these lights for vegetative plants or flowering plants.

They aren’t available as full-spectrum lights.

Product Weight (lbs) Dimensions (inches) Max wattage Total Diodes available
X40 4.5lbs 23.75” x 2.6” x 1.7” 40W 108
X80 8.5lbs 47.6” x 2.6” x 1.7” 80W 216
XD75 7.5lbs 47.4” x 3.1” x 2.3” 75W 432 (216 per side)

Onto the K3 series

Kind LED Lighting Review

A more powerful full-spectrum option, these compact lights are powerful. The max wattage is 288w (although this will cost $595).

This slim series is formulated with the hobbyist in mind – for those who want to grow from the comfort of their own home but want a higher quality product; this is the option Kind has tailored for you.

Name Weight Dimensions (inches) Max Wattage Diode Wattage Total Diodes Available Footprint (in feet)
L300 13lbs 15” x 11” x 3” 210W 15W 6 2’ x 3’
L450 16lbs 20” x 11” x 3” 270W 3W 120 2.5’ x 3.5’
L600 20lbs 25” x 11” x 3” 320W 15W 150 3’ x 4’

And finally, the K5 series

Kind LED Lighting Review

These are the most expensive lights available on Kind’s website that haven’t been marketed for commercial use. With a much higher price point than the other lights on the site (the K5 XL750 will set you back $1245), this is a serious investment.

With that being said, for anyone with more than a casual interest in growing, this is a product marketed towards you. The K5’s main driving feature is the WiFi capabilities – you can connect this light to the WiFi, and then control it remotely.

It makes adjustments much easier and faster and means that you’re always connected to your plants, in a way. This series is for the serious growers, who are looking to perfect their crops.

Product Weight (in lbs) Dimensions (in inches Max wattage Diode Wattage Total Diodes Available Footprint (in feet)
XL750 28lbs 23” x 17” x 3.5” 430W A mix of 3W and 5W 208 4’ x 4’
XL1000 36lbs 26” x 20” x 3.5 650W A mix of 3W and 5W 320 5’ x 5’

Before you buy…

Just to simplify things for you, we’ve compiled a shortlist of the pros and cons of Kind as a brand, and the products they list on their site.

Pros of the Kind LED lights:

High quality

    • The lights are much higher quality than some cheaper brands on the market.
    • Their wide footprint means that top leaves and bottom leaves are both penetrated, to give your plant a strong base and ensure you don’t have top-heavy growth.

Fully customizable

    • If you’re looking for full-spectrum lights, the K3 and K5 ranges are great options, due to their customizability.

Complete control using the K5

    • As well as having control over the spectrum of the lights, the K5 offers you even more control. If you buy the K5, you can set timers to simulate the natural cycle of the sun.

Offers both bar lights and full-spectrum lights

    • While their range of bar lights is small, they do offer this option to anyone who prefers using bar lights

Cons of the Kind LED Lights:

They’re expensive

    • While Kind LED do offer their bar light range, which are much lower in cost than the K3 or K5 series, in general this is an expensive brand
    • This is a brand you should invest in only if you are serious about growing, and have been doing it for some time already, so you’re familiar with setting up your growing station
    • This brand markets more towards professional growers or those who are growing a higher yield. They have more products for this market than for hobbyists or those with a small yield

Some set up issues with the WiFi

    • While this is a natural teething problem that happens with many products that require internet access, it’s something to bear in mind if you aren’t comfortable or familiar with internet-accessible products.
    • However, many customers who’ve had complaints about setting up one of their K5 range lights have pointed out that Kind has a great customer service team
    • Some have even had their questions answered by the company’s founder, Jeff. This shows that this is a company that truly cares about their customer base. You should have a little peace of mind from this knowledge, even if you run into some problems during installation

Okay, so does it actually work?

I’ll admit, I had high expectations for this brand after seeing the price range. When a brand markets itself as producing $1000+ products, you expect some seriously impressive quality.

It turns out I wasn’t alone. When I looked through the reviews, I found Daniel. He was another customer who was initially scared off by the price tag, but in the end, he took the plunge and purchased the XL750 (part of their high-end K5 range).

Now, it seems like he’s a Kind Convert! Not only did he find amazing results from this product (including the fact that its large footprint treats all leaves, including the bottom leaves), but it was cheaper than expected to run – no huge spikes in electricity bills!

As a recent convert to Kind LED’s, Daniel isn’t alone in his support for the company. Many of the customers who’ve left satisfied reviews report being users of the company for years.

The fact that customers like Dalyn (a customer for two years) keep coming back speaks to the high quality of these lights.

Many more customers have purchased multiple lights, fitting their entire grow room with Kind LEDs.

Of this group of dedicated customers, there are many who’ve been growing for years, like Curtis.

Curtis’ Story:

He grew in his basement for years with HPS lighting, but after moving, he was finding that the HPS lighting was causing a serious increase in temperature. This meant that he was constantly watering his plants to keep them from drying out, and his energy bill was rocketing up.

Eventually, he chose to invest in the KL750 (from their K5 range) and saw immediate changes. The temperature dropped, meaning that he wasn’t having to constantly water to stop his plants from drying out.

Even better, due to the more optimal environment, he was putting his plants in, he actually saw an increase in his yield!

So, should you buy this? And if you want to, where can you find it?

There’s a range of products available to purchase on Kind’s website, depending on your needs. The bar lights are the cheapest available, but you should bear in mind that these are non-customizable.

They’re probably better to add to your current collection of lights because they can’t give your plants everything they need during all stages of growth. (At least not on their own).

The K3 series is popular for its’ customization – whichever stage your plants are in, you’re sure to be able to change the settings to get the best possible yield. While being small, it has some serious power behind it at up to 288W and has proved popular among customers.

The K5 series builds on the success of the K3 and introduces new features like WiFi access, which is one of the main selling points for many. However, before leaping in to buy this product, you may want to stop and consider the cost.

While some of the products say they’re marketed towards hobbyists (and that may be true of the bar lights), this isn’t a brand I’d recommend for hobbyists.

They’re expensive investments, which could cost you upwards of $1000, so this isn’t a purchase for the faint of heart.

This is definitely a brand that caters towards professionals, rather than those who are interested in growing as a hobby or are growing a small yield. If all you’re doing is growing for yourself, then spending $1000 on a light may be hard to justify.

If you’re a professional grower, in need of precise controls over your lighting, then this may be a worthwhile investment.

If you’re interested in buying, these products are available from the Kind LED website, and there’s a limited range of them on

So, after all that, what do I think?

There are a lot of positive reviews of Kind’s products, showing that they’re a solid company producing high-quality products. Clearly, with the introduction of their K5 series, they’re keen on bringing an innovative design to the table.

Having a WiFi-compatible LED light is a massive bonus to any growers who want to have precise control over their yield. The remote access gives you more control and more comfort in knowing what’s going on inside your grow room at all times.

However, this is an expensive brand. Their products are a serious investment and not one to be taken lightly. Their products obviously come with a lot of features that aren’t standard (like the WiFi access).

While these seem cool, fun, and intriguing, due to the cost, you should stop and think before buying. Do you need an LED light with these functions?

If you’re a hobbyist, this might be a brand to avoid for the time being. But if you’re a seasoned grower – a professional who knows what they’re doing and is handling a large yield – then this might be a seriously good investment for you to make.
