This unpaid, independent video follows my earlier one comparing "1000 model" grow lights.
We'll build on previous concepts, so be sure you've seen the first one.
What's new in this update?
Some lights from ViparSpectra.
Third party lab tests for comparing in-house reports.
I'll show things to watch for when sellers list efficacy specs.
And there's a new arrival to the market.
Could it be a new contender for the SF1000?
Here's an outline for this video's content.
First let's tie up some loose ends.
Mars Hydro hadn't sent a TS600 test report.
I estimated 1.8 to 2 micromoles per joule, despite the sticker and website claims.
My calculations were correct.
They've finally sent this report showing a PPE of 1.92.
So it really wasn't as great as they'd claimed.
For the TS1000, I only had an old report.
But finally I was able to get newer data, showing a PPE of 2.2.
So it's a decent option.
These in-house reports are great, but not always perfect.
The best option, the gold standard, is independent 3rd party lab testing.
Both Maxsisun and ViparSpectra were interested in this to verify their product quality.
So kudos to them!
Maxsisun's MF1000 in-house test report showed a PPE of 2.14.
They sent a unit to Light Laboratory (an independent 3rd party lab).
And their testing showed a PPE of 2.25 micromoles per joule.
This further verifies Maxsisun's authenticity.
ViparSpectra had provided a report for the XS1000 showing a PPE of 2.2.
They sent their light to the same lab which reported 2.34 for the efficacy.
A solid number.
They also tested their budget grow light, the P1000.
That LED's efficacy is 2.19.
So both of ViparSpectra's lights are efficient and worth consideration.
But certainly not as high their website originally claimed.
You know, the nice thing with independent lab testing is that any seller's light could
get tested.
If a company falsifies their reports, a reviewer or even competitor could check to see if fraud
is going on.
It's an excellent way to keep the market honest and hold sellers accountable.
I sent a couple units to Light Laboratory as a bit of an audit.
Was Mars Hydro's TS1000 report accurate?
The numbers were extremely close.
What about the SF1000?
The in-house report showed 2.46 and Light Laboratory shows a PPE of 2.41.
That's pretty close.
Yes, yes, yes, but... look at the Total PPF.
Spider Farmer's report shows 249 micromoles.
But independent testing shows 222.
That's only 89% of the light output.
What's going on?
Well, look at the actual power draw.
In Spider Farmer's test, the SF1000 ran at 100 watts.
But proper lab tests allow the unit to stabilize.
As it warms up, the power dipped down.
And the light output dropped.
This power drop isn't seen with all LED grow lights.
Some models are rock stable.
Rated at 100 watts and running at a true 100 watts.
In the end, some of the less efficient 100W lights actually output the same PPF as the
SF1000.
Maxsisun's MF1000 and ViparSpectra's P1000 are just as bright.
This brings us to our newest entry: Atreum Lighting’s HYDRA-1000, a direct contender
to the SF1000.
Atreum sent a sample to CSA Group another testing lab.
At first glance the results were surprising.
A PPF Efficacy of 2.7!
Compare that to the SF1000 which is between 2.4 and 2.5.
I was quite pleased.
Something to point out though: So far, all tests ran at 120 volts (the standard US wall
plug).
But the HYDRA-1000 was tested at 230 volts.
The higher voltage reduces the current which boosts efficacy.
It's not a massive difference, but the HYDRA report isn't a true apples to apples comparison.
More like apples to quinces?
Just pay attention to a light's voltage when tested.
If you miss that detail, it might appear more efficient than it is in your application.
Here's another way sellers may boost specs.
PAR photons fall between 400 to 700 nanometers.
But the trend is to replace 1 or more diodes with a Far-Red to boost growth.
And so the light's stats take a hit.
Think about it.
You lose some of the red photons that count towards PPF and they get shifted outside of
the counted spectrum as Far-Red.
Shouldn't those photons get counted too?
Look again at the CSA Group report.
There's photosynthetic photon flux (400 to 700).
But also that extended range including Far-Red.
CSA Group designates this as Photon Flux, from 350 to 1000 nanometers.
They have the PPF efficacy but also the Photon Efficacy derived from that broader spectrum
range.
This includes those Far-Red diodes.
And the light specs get a boost.
It's something to watch for.
Companies may list the larger photon efficacy and photon flux stats without showing the
spectral range.
You might assume they mean standard PAR until you dig into their reports.
The Light Laboratory reports make less of a distinction.
But by labeling the expanded spectral range, you see the resulting boost.
Often this isn't a massive difference.
But if it matters to you, be sure to pay attention.
Three takeaways are this: Take note of a light's true operating wattage in case it dips lower
than expected.
When looking at reports, check to see what voltage was used.
And pay attention to spectral ranges as some sellers inflate their stats by counting photons
outside of PAR.
Let's look into each light.
Previously we saw 3 budget models.
Maxsisun's PB1000 was the best value having a good power factor, basic dimming and more
light output.
That model's been upgraded to the "Pro" which features a Far-Red diode, a remote control
for dimming and daisy chain power.
So this thing is an even better option than ever.
And now I have good data on a fourth budget model: ViparSpectra's P1000.
It's rather efficient with a low price tag.
It includes Far Red.
The dimming knob is easy to access and feels sturdy.
The general design is solid with a finned heat sink for improved thermal management.
I took standard PPFD readings and ViparSpectra's P1000 performed well.
Compared to the others it was just slightly behind Maxsisun's PB1000.
So it's also a great budget option.
Certainly better than the SF1000D or TS600.
At this point, those two should just get dropped from the line up.
I only recommend the PB1000 Pro or the P1000.
Technically, the P1000 had the highest scoring lab tests so, depending on the price, it could
possibly get you the best bang for the buck.
It's nice to have a couple budget options to choose from.
What about the premium models?
ViparSpectra's XS1000 is more efficient than their budget model.
It draws 20 extra watts which yields 28% more light output.
So while the design is very similar, this a premium LED.
My PPFD readings seemed to match well with the lab reports.
These are some very respectable numbers.
Compared to their cheaper P1000, the premium price is quite justified.
If you need higher light levels in a small footprint, the XS1000 is a great option.
I like both light models and I'm glad I can now share data on these systems as well.
Our other premium contender is this HYDRA-1000.
Atreum Lighting is an American owned company that designed a direct challenger to Spider
Farmer's SF1000.
One unique difference was the interesting diode spacing.
While Maxsisun and Mars Hydro offer lights with reflectors designed to redirect photons
to the center, Atreum has taken the opposite approach.
The center diodes are spaced out more.
And diodes get tighter as they approach the corners.
The idea is to get more consistent light distribution.
Rather than a huge spike in center readings with weak corner lighting, it's meant to even
things out.
Ideal for broad open canopies or for grow tents.
This would have made the HYDRA-1000 unique if Spider Farmer hadn't done the exact same
thing with yet another product revision.
Wait they changed the SF1000 again?
Yep.
We'll get to that.
But let's take a closer look at this HYDRA.
It has top notch Samsung diodes and Mean Well driver.
The dimmer is a little different.
The digital wattage display responds as you dim it.
It seems cool enough.
But it's not showing the wattage at the wall.
Rather, indicates how much power is going from the driver to the LED board.
As the readout displays 100 watts, it really pulls 118 at the wall.
So as you dim it, the display always underreports the true power.
Not a big deal as long as you're aware.
I'm more impressed with the detachable mounting plate.
The driver and dimmer blocks can be placed away from the LEDs and outside of your tent.
A more useful feature that Spider Farmer doesn't offer.
Let's look at my real world PPFD readings.
These represent a typical 120V connection.
The HYDRA ran steady at 114 watts.
And this yielded some very nice light levels.
The only brighter lights were the ones that sucked up more power, the TS1000 and XS1000.
So comparing the HYDRA-1000 to the SF1000, I had trouble finding a single advantage that
Spider Farmer offered.
Perhaps some beefier power connections?
But photons are what grow plants.
And the HYDRA generates a lot more.
Back to the SF-1000.
I purchased this revised unit in March 2021 for lab testing.
I had no idea it was updated.
I was happy to see they've added diodes!
From 218 up to 270.
Less current running through each diode should help with heat management and efficacy too.
But are these even the same diodes?
At the time of publishing this video, Spider Farmer still hasn’t updated their listing.
So who knows which model you’ll get if you buy one.
When I tested this brand new SF1000, it had lower PPFD values than the previous model.
This light should be a step forward, but the lower running wattage means less light output.
Combine that with the premium price and I'm not sure I'd buy this light anymore.
I'm not saying it's a bad light.
But it doesn't stand out as the most efficient.
And it's certainly not the brightest.
Each light in this video can do a decent job.
They'll perform much better than lights from a few years ago.
But which will you get?
It can be hard to decide.
So let's compare specs, side to side.
To see some finer details, this chart compares the updated line-up.
But there are a few key specs that are most important.
First up is the efficacy.
Here are the models worth buying ranked from lowest to highest.
At this point, the HYDRA-1000 has become the leader of the pack.
Even when you account for the voltage, Atreum's light matches or even exceeds Spider Farmer's.
Of course, efficiency is important, but total light output is what drives growth.
So these are my more current PPFD readings side-by-side.
And here's the average of those readings which seem to match up well.
Here's the Total PPF from test reports.
Mars Hydro still leads the pack with that 150W luminaire.
But now we have the XS1000 and HYDRA-1000 which also push the wattage higher for boosted
light levels.
Higher light output is good, but at what cost?
By overlaying those metrics, we can see where the best values are.
Prices have radically changed since my previous video.
Right now we're seeing a price war!
As we move to the right, the lights generate more photons per dollar spent.
That SF1000 lags severely with less micromoles per dollar and that's after a major price
drop.
None of this accounts for coupons though.
Let's plug in some discounts.
Currently, there are some crazy deals which makes the Maxsisun and ViparSpectra units
amazing buys!
The P1000 and PB1000 Pro aren't the brightest or most efficient out of the pack.
But for the price you pay, it's hard deny their value.
Here are the leaders in each category.
For efficacy, the HYDRA-1000 takes the gold followed by the SF1000 and then the XS1000.
For total light output, the winner is the TS1000 then the HYDRA-1000 and XS1000 which
probably tie for 2nd and 3rd.
As far as value goes, the PB1000 Pro wins, followed by the XS1000 and P1000.
But that can change overnight, so run the numbers as you plan your purchase.
Which ones would I recommend?
First, I think each light has something to offer.
It's not like one is complete garbage while another is vastly superior.
But clearly some have an edge.
If you're a hobby gardener on a tight budget, consider the P1000 or PB1000 Pro.
The P1000 is simple but just a little more efficient and brighter.
The PB1000 Pro is a little fancier though, so it's really a matter of preference.
Both offer lots of light for a low upfront cost.
But these lights are less efficient than some, so they're ideal for seasonal growers or those
who have low electrical rates.
If you'll have the light in your living space, the hooded ones are nice.
These are a little less likely to sear holes into your retina as you walk by on your way
to the kitchen.
For a smaller area the MF1000 is a great option.
The TS1000 costs a little more but is good for larger spaces.
These are fine in tents, but they’re nice when you don’t have side reflection.
If you're growing year long, consider a more efficient unit like the SF1000 or HYDRA-1000.
They won't take as long to see a payoff.
And both are optimized for grow tents.
At current pricing, they're worth the investment.
And they'll generate less heat per watt.
For those high light medicinal crops, the HYDRA is the better option though, having
higher output.
Or consider the XS1000 which has similar PPF.
It's a little less efficient though.
But if you can get it at a discount, you'll get a great value.
The TS1000 is still the brightest out of the pack, but it sucks up the most power and is
not as efficient.
All three offer boosts in light output which means higher yield.
So any one of these is a great option for those mari-tomatoes.
Previously, I graded these companies based on their accuracy and transparency.
Mars Hydro was quite a let down.
After dealing with them further, they did send updated reports.
And they started to correct their listings.
But I still saw multiple inconsistencies and they do not disclose their reports on their
site.
So I'll give them a C+ for moving in the right direction.
ViparSpectra removed false PPE numbers from their site which is good.
They haven't posted their third party reports though.
And it’s hard to find any PPE or PPF specs.
But they did reference the data on their Amazon listing.
So I‘d give them a B.
Atreum Lighting has done better.
They openly list the PPE.
On their site they even have a direct link to their test report.
So you can see the data if you want.
Nothing was falsified or inflated.
Although it would be nice to see a 120V test report for comparison, I would still give
them an A. They used a third party lab and shared the data.
I hope this gives even more info on some leading "1000" model grow lights.
The objective isn't to bash any brand or unit.
Rather, to get you the most complete and accurate info.
There's more to selling lights than simply assembling a social media army.
I try to get companies to compete on honesty, product quality and pricing.
Competition is good for consumers and it fuels innovation.
