We developed the grow light calculator to provide a scientific way to analyze and compare grow lights. Our calculator uses Photosynthetic Photon Flux (PPF) along with wattage and cost to calculate the efficiency, coverage area and harvest potential of different grow light fixtures. You can enter your own data or view data for the fixtures that we have preloaded. Our Grow Light Comparison table below allows you to easily compare the key data for different grow light fixtures.
The Grow Light Calculator is part of the Coco for Cannabis Grow Light Guide. We encourage you to read our Grow Light Metrics Primer to learn what all the data means. We explain how the calculator works and the science behind our formulas in our article, “Calculating Grow Light Efficiency, Coverage & Harvest Potential”.
The new Mars Hydro TS series really is a game changer. They deliver performance that until recently was only available on models that cost 4-5 times as much. The TS series are Quantum Board style fixtures which use Epistar 3030 chips. The photon and cost efficiency of these lights forced us to reconsider everything about how we recommend grow lights. We no longer recommend HID lights to new growers because of these Mars TS series LEDs. They are an excellent value for money, and they are our top recommendation for most growers. We tested the TS 1000 model in this product line. Be sure to see our complete Field Test Report The Mars Hydro TSW 2000 is a dimmable full spectrum LED Grow Light, which offers all the same qualities as the TS 1000, with more output and coverage. It is roughly equivalent to two of the TS1000 lights. The TSW 2000 is very similar to the TSL 2000. The difference is the shape. The TSW is a square designed to cover a 3’ x 3’ space. It is ideal for 3’ x 3’ tents and grow spaces. It has an ideal flowering distance of 18” above the canopy. The data here come from a test that Shane did. These are typical results from an HPS light with a good reflector. We provide the information and the links as a representative example of a 600w HPS light for comparison. The source data for this fixture comes from integrated sphere testing by Bruce Bugbee. The Values reported as “Manufacturer’s Reported Data” Are the Total PPF numbers from that sphere testing.

Using the Grow Light Calculator
You can enter data about any grow light fixture. However, in order to get an accurate calculation, it is important to understand the data and conversion factors. Watch the video and read below to learn about the PPF data that you need, where to find it and how to use it in the calculator.
Grow Light Calculator Video Tutorial
Enter the PPF or Photon Efficiency
In order to calculate efficiency, coverage and harvest potential we need to use Photosynthetic Photon Flux (PPF) data. If you have a light fixture in mind, look for PPF or Photon Efficiency (PPE) data in the manufacturer’s literature or on their website. Manufacturers of high efficiency lights will usually report this data because it is a selling point. For most grow lights, PPF values are between 100 and 1500 µmol. Photon efficiency values are usually between 1.00 and 3.00 µmol/w.
PPF (Not PPFD)
PPF values are often called “PAR Value” or “Total PAR”. They measure the total amount of Photosynthetically Active Radiation (PAR) that a fixture will produce. This data will be reported as “µmol” or “µmol/s”. You can enter this data in the Grow Light Calculator in the field labeled “µmol”.
Unfortunately, many manufacturers of low-quality lights do not report PPF data. They instead try to manipulate Photosynthetic Photon Flux Density (PPFD) data to convince growers that the lights are more powerful than they are. PPFD is a measure of the density rather than the quantity of photons. The data reported in PAR maps is PPFD data. PPFD values are properly reported as µmol/m2/s. If you see the “m2” in the label, then it is PPFD data which cannot be used in the Grow Light Calculator.
Use Photon Efficiency Data
It is more common to find a Photon Efficiency rating. Photon Efficiency is often abbreviated as “PPE”. It is a number usually between 1.00 µmol/w and 3.00 µmol/w. The label may say µmol/w or µmol/j, there is no difference. We can use photon efficiency ratings instead of PPF values in the calculator.
Photon Efficiency is simply the PPF divided by the power draw. Enter this value into the field labeled “µmol/w”. The calculator will multiply the photon efficiency by the number of watts to estimate the PPF in µmol.
Read more about Grow Light Metrics in our Grow Light Metrics Primer.
Select Calculated, Total or Usable PPF
There are three ways that PPF values are measured or calculated. PPF values may be a “Calculated PPF”, or they may be measurements of “Total PPF” or “Usable PPF”. In our grow light calculator, you can select which type of PPF data that you want to input. The default is set to “Calculated PPF” because this is the data that most manufacturers provide. If you click on the drop-down menu, you can select Total PPF or Usable PPF.
If you are using manufacturer’s data, you should assume that it is a calculated value. This is most obvious when the PPF data that they report is directly related to the efficiency of the LED diodes that they use. Several manufacturers of high-end LEDs publish data from lab testing. You should select “Total PPF” if you are using data from lab testing. The data from our field test reports are Usable PPF values, however manufacturers generally do not publish Usable PPF data.
When you select “Calculated PPF” or “Total PPF”, we use our formulas to estimate the Usable PPF. When you select “Usable PPF” we do not make any adjustments. The calculator will report the new PPF value as the “Estimated Usable PPF”. All other calculations for efficiency, coverage and harvest potential are then based on the Estimated Usable PPF.
Read about the science behind our formulas in our article, “Calculating Grow Light Efficiency, Coverage & Harvest Potential”.
Questions about the Grow Light Calculator?
If you have questions about the metrics and what they mean, please see our Grow Light Metrics Primer. If you have questions about how to use the calculator or our calculations, efficiency ratings, or formulas, please see our article, “Calculating Grow Light Efficiency, Coverage & Harvest Potential”.

Unbiased Testing and Reviews
This guide is an independent resource for growers. We do not accept advertising and do not receive compensation from manufacturers for testing or for including their fixtures in our guide. We will always report accurate information and give our honest evaluation of each fixture.

We want to equip you with the knowledge and information so that you can make the best grow light decision for your cannabis grow.
