To learn more about Spider Farmer SF 1000, we decided to do our own investigation. We included the full results in this in-depth Spider Farmer SF-1000 grow light review article.

Let’s get started with the review!

Spider Farmer SF-1000 Design Review

Before we review Spider Farmer SF-1000 performance, let us discuss first the design for a minute.

The Package

My Spider Farmer SF-1000 arrived well-packaged. The LED grow light needs some extra protection to prevent damages during shipping, and the company does a wonderful job in this regard.

When you open the package, you’ll find the LED grow light as well as the hanging equipment, a few plant labels, a measuring tape, and a user manual.

Structure And Design

The LED grow light feels relatively heavy on the hand. It holds a good chunk of aluminum that accounts for most of its weight.

Attached to the aluminum plate is the light panel. It has 208 LM301B LEDs that are insulated with waterproof material along with the board itself. The power cords of the device are also well insulated.

The diodes are made by Samsung, so they are among the highest quality LEDs found on the market.

The driver of the device is manufactured by MEAN WELL (an excellent brand of power supplies) and is fixed to the lamp.

Because it has no added built-in equipment, such as cooling fans, Spider Farmer SF-1000 is flat-shaped, unlike most LED grow lights.

Spider Farmer SF-1000 Performance Review

Spider Farmer SF-1000 has a light output of around 16500 lumens. Most of its LED diodes emit light in the 3000K and 5000K range of the spectrum, and the rest generate deep red light and infrared light.

The above ratings show us that the light generated by the device includes nearly the full spectrum of light. However, to assess the intensity of the generated light that is useful for photosynthesis, we need more accurate measurements other than lumens and kelvin.

We have to test the Photosynthetically Active Radiation (PAR) output of Spider Farmer SF-1000 to learn more about its usefulness to plants.

One way of assessing the PAR of a grow light is to measure its PPFD values at a particular distance using a PPFD light meter (learn more about growing plants with lights).

Here are our PPFD measurements of the Spider Farmer SF-1000 at a distance of 12 inches (30 cm). This is the hanging height recommended by the manufacturer for the flowering stage of indoor plants.

Those values show that Spider Farmer SF-1000 generates high intensity of useful light.

To appreciate these PPFD measurements even more, let us use them to calculate the values of the Daily Light Integral (DLI). This is the cumulative amount of PAR reaching your plants every day.

Assuming that on average you’ll turn on the light for 16 hours a day, then the DLI values of Spider Farmer SF-1000 at a distance of 12 inches from your plants will be as follows:

We should mention that plants with the highest demand for light can grow amazingly with a DLI of around 20 to 30 mol/m²/d.

So, long story short, you can grow anything under Spider Farmer SF-1000, including vegetables and fruits.

It is important to note that the flowering footprint of the Spider Farmer SF-1000 is 2ft × 2ft (0.6m × 0.6m). So, it’s difficult to grow heavy-flowering and fruiting plants outside that coverage area.

But, the vegetative footprint of the Spider Farmer SF-1000 is 3ft x 3ft (0.9m × 0.9m), because the plants need less intensity of light in their vegetative phase.

Power Consumption And Efficiency

Spider Farmer SF-1000 draws around 96 watts of power. This means that this grow light packs energy efficiency that you will hardly notice an increase in your electric bill when running the light.

But the question is, how efficient is this device at turning watts to light energy?

The average PPFD of the light at a hanging distance of 12 inches is around 531 μmol/m²/s, so its PAR (PPF) output is close to 240 μmol/s.

That means that the PPF efficacy of Spider Farmer SF-1000 is approximately 2.45 μmol/J. This value is phenomenal when you compare it to that of other grow lamps.

For example, a popular competitor of the Spider Farmer, the VIPARSPECTRA Pro Series P1000, has a PPF efficacy of around 2.1 μmol/s/Watt.

Upgraded: ON/OFF Switch + Dimming And Daisy Chain Function

Old Spider Farmer models did not have ON/OFF switches, but the company finally upgraded their LED lights to include that basic feature.

The old lights had a dimming function, but the dimmer was hard to reach because it was inside the driver.

The newest models have their dimmer knobs on the outside, so you can decrease the light intensity of your grow light with ease.

Finally, the newest Spider Farmer SF-1000 has a daisy chain function. The daisy chain feature allows you to connect multiple SF LED lights to each other, which gives you more control over your grow light setup and is able to support a wide area on your grow tent.

Heat Dissipation

The Spider Farmer SF-1000 does not have cooling fans attached on its grow light body. You might be wondering how it remains cool will all the heat generated by its LED light. Here is where the aluminum body comes into play.

The aluminum’s great surface area and high thermal conductivity enable it to act as a heat sink. It collects all the heat from around the LEDs and disperses it gradually in the atmosphere away from the plants.

The aluminum heat sink has several unique advantages compared to grow lights with cooling fans attached.

The Spider Farm LED light does not have a fan. That means it produces less noise during operation, saves you a great deal of space, and also it requires less power to keep this grow light running. Contrary to LED grow lights with fans they produce more noise during operation and also need that extra juice to keep the fans running.

Spider Farmer SF-1000 is not the only grow light that uses aluminum to remove heat. And in our opinion, this method of heat dissipation proved to be the most effective because the majority of grow lights nowadays rely on it.

Yet, many gardeners believe that the heat sink of Spider Farmer SF-1000 is not as powerful as that of other grow lights, such as Mars Hydro TS 1000.

Note: The aluminum of the Spider Farmer will get hot as soon as the device starts running. You don’t have to worry about it because that’s the heat sink doing its job.


Now to the question most of you are wondering about: will this grow light help produce a higher yield to your plants? When it comes to cannabis cultivation, yield in grams per watt is perhaps the most important measurement for an indoor plants grower.

According to the manufacturer, the maximum yield of Spider Farmer SF-1000 is around 2.5 grams/watt. We advise you not to pay much attention to that measurement because it’s irrelevant and a bit exaggerated.

As reported by many growers, the average yield you can pull from the SF LED light is around 1.2 grams/watt, which is also very good.

Spider SF-1000D Overview

The SF LED grow lights released a slightly altered version of SF-1000, called SF-1000D.

This SF light is more affordable than SF-1000, but this price advantage comes at the expense of other features.

For instance, the SF-1000D does not use a MEAN WELL driver, which is a big downgrade.

Also, the LED light uses a different type of Samsung diode (LM301D) that are less efficient and dimmer than LM301B diodes.

The PPF efficacy of SF-1000D is around 1.9 to 2 μmol/J, around 80% of that of Spider Farmer SF-1000.

Considering the cheaper price, we recommend the SF-1000D for first-timers or beginners in indoor plant gardening who are still learning how to successfully grow plants indoors, or for those who are on a tight budget.

Summary & Conclusion

Spider Farmer SF-1000 is a powerful grow light under which you can grow the most light-demanding plants. And we can say it is one of the best LED grow light on the market with its quality components and bang for one’s buck features.

One of the top features of this SF LED light is its low power consumption, all thanks to its LED diodes and using Aluminum as a heat sink. The light only consumes around 96 watts with a PPF efficacy rate that stands around 2.45 μmol/s/Watt.

Spider Farmer SF-1000 puts out a mixed light that covers most of the spectrum. And its PAR output is adequate for most plants, including the heavy-flowering ones.

The device has no cooling fans and instead it uses an aluminum board to dissipate heat.

As for the design, the Spider Farmer has a simple flat shape. It is pretty much a lighting board attached to an aluminum plate and a driver.

The LEDs and the driver are manufactured by Samsung and MEAN WELL, respectively. Both companies are two of the leading brands in the LED industry.

Spider Famer SF-1000 retails at an affordable price (you check the price here on Amazon), and taking into consideration everything we mentioned above, we highly recommend this light for any type of plant you want to grow inside.
