HOW TO COMPARE LED GROW LIGHTS?
If you have been researching LED grow lights for your plant growth facility, you have likely been bombarded with a variety of metrics that lighting manufacturers use to market their products: watts, lumens, LUX, PAR, PPF, PPFD. In our opinion, you want to buy a lighting system that delivers the required amount of light to your plants. In order to explain the correct method for evaluating a horticulture lighting system, let’s first highlight two of the metrics used today that you need to avoid:
RULE 1: DON'T FOCUS ON THE WATTAGE OF THE LED'S. Do you use 5W, 10W, or 15W LEDs? We are asked this question on a frequent basis, but the wattage of the LED use in light does not tell you anything meaningful about the lighting system's performance since LED and fixture efficiency varies widely. Remember, the LED wattage is a system input, and growers care about the system output--PAR Output. Hence, the lighting system using 10W or 15W LED wattage doesn't deliver more light to your plants than lighting system using 5W LED wattage.
RULE 2: DON'T LOOK AT A SINGLE PPFD MEASUREMENT. Unless you are growing a small plant directly under your light, a single PPFD measurement doesn’t tell you much. By clustering the LEDs closely together and using narrow beam optics, it is very easy for a manufacturer to show an extremely high PAR measurement directly under the fixture. However, unless you are only growing one plant in this exact location, you need to know how much PAR is being distributed across the entire canopy.
Three important questions you should look to be answered when researching LED grow lights are:
Question 1: How much instantaneous PAR from the fixture is available to plants (measured as PPFD)? Question 2: How much PAR is being distributed across the entire canopy? Question 3: How much wattage is used by the fixture to make PAR available to your plants?
The three key metrics of the V300 used to answer these questions are:
PPFD directly under the Fixture
PPFD is photosynthetic photon flux density. PPFD measures the amount of PAR that actually arrives at the plant, or as a scientist might say: “the number of photosynthetically active photons that fall on a given surface each second”. PPFD is a ‘spot’ measurement of a specific location on your plant canopy, and it is measured in micromoles per square meter per second (μmol/m2/s).
PPFD over a 2’x2’ Area
If you are growing over a 2’ x 2’ area, you need to review the PPFD levels over the entire area to calculate the average light level the lighting system is providing. If you only had a center point measurement you may assume a fixture is extremely powerful. However, you would need multiple measurements across the 2×2 grow area to calculate the average amount of PAR that is provided by the fixture.
Actual Power Draw
In general, for well-designed full spectrum lighting system, the higher actual power draw is, the higher PAR Output a lighting system emits to plants. So how much actual power draw do you get when buying other 600W(60x10W) LED grow lights?

Anyway, construction wise the light itself feels pretty rugged. Metal housing, nice large fairly quiet fans. The noise output is comparable to PC fans. They actually appear to be PC fans, which is perfectly fine, PC fans work great at cooling electronics seeing as that's what they are designed for. I chose the 450W version of this light mainly because of the ability to switch off the "bloom" spectrum of lights. After further research, however, I've found that this is not something you'd actually want to do, just leave both on.
So, let's move on to the light output. I mean, that's what everyone cares about, right?
# Manufacturer's Specs
VIPARSPECTRA lists the light as having a PPFD (aka PAR rating or PPF) of about 619 μmol/s at 18" directly in the center and a lovely 1186 PPFD at 12". They do not say whether they measured this in a tent or in free air. They also don't say what they used to measure it. For this price point, 619 PPFD sounded pretty good. I had assumed they measured this in a tent. The other lights on Amazon around this price are right around 500 PPFD at 18", so that's a pretty big jump.
Now here's where we get into some shady business. The manufacturer says you can use this for the vegetative state (when a plant is just growing) at 24", but they rate the exact center for 619 PPFD at 18"... plants need about 500~600 in the vegetative state, though generally more is better, 500 is considered the minimum. So 18" is the actual vegetative height. They also say to use 18" when your plant is flowering, but 619 is too low for flowering since you'd want 1000~1100. Based on their chart that would mean 12" for flowering. So their claims of 2'x2' for flowering and 2.5'x2.5' for veg are wrong, even by the listed PPFD.
# Actual Specs
So what are the actual specs of the light? At 18" in a tent, you're looking at right around 710 PPFD. That's 91 more than the rated output. I was actually really surprised by this. Based on the readings I took, you don't get down to below 500 PPFD at 18" until about 9" out from the center. So, you can veg with this light in roughly a 1.5' x 1.5' area if you want to keep things optimal, but you could probably get away with 2' x 1.5' if you were stretched for cash and wanted more area. At 24" the rating was around 350 PPFD in the center, not something that would be good for veg at all unless you want your plants to stretch a lot. Now that'd probably be fine for plants just starting to leave the seedling stage or plants that never get very large (herbs, microgreens, etc), but not for plants that get large or bushy.
Now, what about flowering? At 12" the rated output is 1186 PPFD, measured in a tent it's actually a whopping 1273 PPFD in the center and just over 1000 PPFD at about 9" from the center, with it quickly dropping off after that. The problem is at 12" my plants actually got some minor light burn, so 14" seems the most optimal height for flowering. At 14" it was just under 1100 PPFD, but the area of >1000 PPFD was only about 1'x1'. So, if you're flowering what I believe most of you are flowering, that's 1 plant in optimal conditions or 2 in acceptable conditions.
Note: Their entire chart is slightly under what you can expect in a tent. I got 100~120 PPFD on the edges where they say to expect 70~90 PPFD. I did measure the light with the bloom light off. At 18" it drops to 370~380 PPFD, about half. Just don't bother with it, leave both on.
The light output is a bit better than advertised. The usable area is mixed because the PPFD they measured seems accurate, however, they state outright in the product description that the area is a lot larger than it is. But, it all depends on what you are growing.
Seedlings only need right around 150-200 PPFD. In fact, stronger is bad. Sadly, seedlings like a little IR and I believe the IR lights are on the bloom side, so you'd still want to run both light settings. You could have a very large herb or microgreen garden with this light. If you are growing something *else* then stick with 2 plants max.
# Final Thoughts
If you are set on getting a "blurple" (a mixture of individual LEDs, mostly blue and red) LED that's in this price range, this is the one to get. There are some DIY solutions that are cheaper and just as good or the same price and better if you are willing to do a little work. So look into COBs or quantum boards if you are fine with a bit of DIY. If you just want something you can take out of the box and use, this is perfect for that and you'll have to spend a good bit more to beat it.
I took off 1 star for the misleading usable area sizes, most people don't know what PPFD is or how to use it, so they won't know those are wrong. They will trust the manufacturer's specifications and spend more time in the vegetative state with more stretch and then when flowering they'll get smaller flowers or less fruit as a result. If you stick to my recommendations you'll see faster growth and larger/more flowers/fruit.
I took off half a star for the bloom light disable (that, again, you should not use) because it's misleading. I took off another half star because while this light is cheap for a blurple light, there are even better lights out there for the same price (or less). They just aren't on Amazon.
All PPFD measurements were taken with an Apogee MQ-500 inside of an iPower tent. Pictures attached are of the meter while measuring the light's output.
Don't get me wrong 2 300's will work but only for small plants as your plants will out grow the 300's fairly fast. You will get better results and coverage with the 450's and if you have the money 2 600's would be even better. Without enough light it doesn't matter what method you use soil/hydro or what fertilizer you use the plant will never reach it's full potential.
These are great budget lights for beginners and vets alike and if I can get 3 years + out of them they are worth every penny. Only time will tell from here and I will update as things progress.
