Spider Farmer SF4000 LED Grow Light Unboxing & Review

Spider Farmer SF4000 LED Grow Light on a grow tent

Hello there, this is Sam from Growbuds, and this latest product review is about Spider Farmer SF4000 LED Grow Light.

Spider Farmer SF4000 LED Grow light is probably one of the most popular LED grow lights right now.

If you’re one of us who have seen LED grow lights evolve in the last years, you’ll find this product very interesting.  

The first LED grow lights in the market were the so-called “blurples” most people found  them to be underperforming to say the least. Since then, a lot of companies have developed white light full spectrum LED technology. And came along the Chinese companies who offered the technology for a fraction of the price. 

About two years ago, Spider Farmer unveiled their SF series, and they had a massive success by providing LED grow lights for a lower price. 

This year 2020, they release an upgraded version of their LED Grow lights. This is the product we’re reviewing in this blog post.

What’s inside the packaging?

Spider Farmer SF4000 comes in standard packaging that protects the product and avoids any damage while being shipped. 

It also comes with a user manual booklet and accessories.

Inside the packaging, you’ll see that the light is already assembled.  And you’ll get the standard rope ratchet that usually comes when you buy LED grow lights, or any grow lights. 

You’ll get RJ wires for you to daisy chain lights or connect them to a single controller. There are hanger hooks that you can also use to attach the light.

Spider Farmer SF4000 LED Boards & Diodes

The Spider Farmer SF4000 LED Grow Light has four boards with LED chips attached to a thick aluminum panel. The aluminum panel acts as the heat sink that will dissipate the heat from the diodes.

On each board, you’ll see four types of diodes, which I think are the most important aspect of any LED grow lights.

Spider Farmer is using LM-301B Samsung diodes. The first type of diodes is the 5000 Kelvin white light diodes. The second type is the 3500 Kelvin warm white light diodes. When these two types of diodes merge, you get a full spectrum grow light.

There’s also some Red diodes as well as a few Deep-Red diodes. Spider Farmer claims that these red diodes can accelerate flowering times. I suggest that you check it yourself to understand how these red diodes work—but having them will nicely complete the spectrum.

A great full spectrum LED Grow Light has a whole range of light available to plants and does not just have one red and one blue color frequency. A full spectrum means good support to your plants in all stages, from seeding to flowering or fruiting.

Take a look at the spectrum chart below;

You’ll see the spike in blue due to the 5000 Kelvin diodes and a nice curve of the spectrum’s red side.

Another vital thing to note is that the boards have a coating that protects the diodes from water and impurities. Overall, the light is rated at IP67, which means it works perfectly in humid environments. Whether you are using a grow tent or having a greenhouse, the SF4000 LED grow light will perform well.

Another claim from Spider Farmer is that their diodes can last up to 100,000 hours. It’s pretty impressive, considering most LED grow lights just claim 50,000 hours. You can take this information with a grain of salt. We can’t tell how accurate the claim is but the entire board is well-built, sturdy, yet lightweight.

Now let’s talk about the Mean Well Driver.

Spider Farmer used to have one big driver for the entry-level range, but the upgraded version has two smaller ones. The lights are already connected to these drivers, so it’s plug and play.

Another interesting add-on to this LED grow light is the control module. It allows you to dim down to 20% up to 100%. It has 2 RJ ports, which you can use to connect daisy chain multiple lights on the same circuit. With this, you can control multiple lights using the control module. It’s a huge upgrade!

Pricing & Investment

The Spider Farmer SF4000 LED Grow Light is a Chinese product that might make you skeptical about it. But so you know, most of the LED grow lights in the market are all made in China too.

One of the main reasons why this product is a massive success in the U.S is its price. It’s a powerful grow light and performs just as good as the other grow lights but for a fraction of the cost.

It’s a bit more expensive than a thousand-watt HID setup, but it gives you a great full-spectrum and energy savings in the long run. There are other expensive grow lights out there, but this one is so far one of the best for the entry-level range.

Whether you’re a hobby grower or a commercial grower, looking for products that will last you for long periods and can give you satisfactory results, this product is for you. Or if you’re someone who wants to invest in up-to-date technology without breaking the bank, this light is a good investment.

We’ll be doing a more in-depth review of this light soon. We’ll let you see how it performs inside a tent, and we’ll give you power readings too. In the meantime, you can check out Spider Farmer's own chart, so you have an idea of how powerful this light is at different distances from the canopy.

Spider Farmer SF4000 Watts and Coverage

Let’s talk about the wattage and coverage of Spider Farmer SF4000 LED Grow light.

The power that it draws is about 450 watts, and the efficacy they claim is 2.7. In some places, they claim 2.9, but I’m pretty sure that if we’re talking about Samsung Diodes LM301B, it’s going to be more into the 2.6 - 2.7 range. It’s still good because the other lights out there have the same efficacy unless you have the newest generation of Samsung Diodes.

The Downside of Spider Farmer SF4000 LED Grow Light

It’s also worth mentioning some of the downsides of this product in this review.

The first one is the light itself. It is small. Although it can be a good news for some people, especially when it comes to shipping. 

When it comes to coverage, it will not cover like a bar design or “Array” LED grow light. This product has a square shape, so if you place it in a 4x4 or a 5x5 grow area,  the light concentrates on the middle and quickly dissipates into the edges. It’s a downside if you’re looking for optimal coverage. If you like even light coverage, I would say that you look into bar LED designs instead of this one.

Another thing is the heatsink. A lot of grow lights are improving their heatsink lately with upgraded designs and stuff. But with Spider Farmer SF4000, you’ll just get a simple aluminum panel, and that’s it.

Wrap up

Spider Farmer fine-tuned this LED grow light to include every possible feature you might be looking for in an affordable plug and play grow light.  So far, this is an excellent light.

Spider Farmer SF4000 can cover a 4x4 and 5x5 grow space. My suggestion is that if you’re looking into the flowering aspect, use this to a 4x4 area. However, if you’re looking to veg those plants, the light will work well on a 5x5 grow area.

Let us know if you have any questions or if you think I’ve missed anything. Our next review will include PPFD readings and a comparison with other affordable, and more expensive LED grow lights. We’ll let you know how this product performs against those brands.
