Next Gen Quantum LED Boards: Cheap, Easy & Super Efficient (Spider Farmer Grow Light Review)

Hi YouTubers! I’m Al Gracian, from Quantum Boards! These are some of the latest in LED tech offering
nice boosts in efficiency. DIY enthusiasts have been setting up some
nice systems for years. But what if you just want to buy something
and plug it in? Well, today we’re looking at the Spider Farmer
SF-1000. We’ll look at some specs, some PPFD readings
and compare them to some older LED systems. Wanna know how to decode those mystical micro
mole per joule ratings? I’ll also tell you what I didn’t like about
this seller’s product claims. So let’s dig in! Here’s everything that comes in the box. Hanging hardware, including two rope hangers. A manual and this snazzy card. There’s no significant assembly required. With the SF-1000 we just attach the hanging
cables and we’re all set! Now for these diodes. Some low-end lights might only offer a single
diode color. But Spider Farmer uses a custom blend, optimized
for plants. A nice broad range of colors, rather than
a few isolated bands. Overall, the light looks fairly white. So it’s easy on the eyes. And it’s good for accurately monitoring plant
health. We have a nice MEAN WELL Driver, securely
fastened to the board. A simple package, but the components are well
assembled. No exposed wires. And the board has a rubbery coating, protecting
the diodes from splashes and such. I ran this light for 4 hours in a room that
was 80 degrees Fahrenheit. The back of the aluminum board reached temperatures
from 130 degrees at the corners, to 140 in the center under the driver block. So this does heat up and you should be careful
when handling and positioning the light. What really counts though is how much light
this thing throws. And this light is BRIGHT! Cameras just can’t do it justice. But lumens are for humans, right? So let’s take some objective measurements. My Apogee SQ-520 quantum sensor gives much
more accurate readings when comparing custom LED spectrums. I’m taking PPFD spot readings along a 4 inch
grid, inside a reflective wall measuring 28 by 28 inches. Spider Farmer supplies a PPFD map at 18 inches. So I’ll check that. Also 24 inches and 12 inches. Right away I noticed some strong consistent
numbers at 24 inches. With an average PPFD of 375, running this
light at a cycle of 18 hours on and 6 off would produce a DLI of 24.3. And that’s actually quite respectable! I’m phasing out this old LED, so I’ll
take some readings for comparison. They’re both pulling about 100 watts at
the wall. But this UFO is older tech. It has to divert power to a cooling fan and
in general the LEDs just aren’t as efficient. At all of these distances, I see much stronger
numbers from the Spider Farmer LED. Efficacy. A crucial spec when comparing two grow lights. How efficiently does a light convert electricity
to plant-usable photons? Are you familiar with “lumens per watt”? Well, in horticulture we can compare the micro
moles per joule. One joule per second is a watt. So this “j” deals with the electricity used. And this unit? This is the PPF, the amount of PAR photons
being emitted, as measured in micro moles. The higher the number, the more photons your
light pumps out per watt of power consumed. Higher is better! The SAMSUNG Diodes enable this light to boast
an efficacy of 2.7 micromoles per joule. For an entry-level, consumer-grade grow light,
that’s really good! A couple years ago LED manufacturers were
excited to offer 2.0 or 2.2 ratings. And even right now, some older LEDs might
still be 1.8 or less. Does that mean this 100 watt LED could replace
a less efficient 1000 watt model??? Well, that’s what the seller had said in their
Amazon listing. And I’m gonna say ABSOLUTELY NOT! That’s an overinflated claim and here’s
why. To achieve the same PPF output as a 1000 watt
model, you need to replace an LED that only yields 0.27 micromoles per joule! Look at these rather dated specs showing some
reference numbers from a few year back. Even then, LEDs were anywhere from 0.89 to
1.7 micromoles per joule. So what’s a realistic example justifying an
upgrade? Let’s say that you have an older LED, rated
at 1.8 micromoles per joule. It’s 150 watts. Multiply them for a total output of 270 PPF. This SF-1000 draws 100 watts at 2.7, so it
too would output 270 PPF. Thus, this newer quantum board should be able
to replace a 150 watt LED or maybe a little higher, perhaps 250 watts. But not as high as a TRUE 1000 watts. To test this estimation, I dug out a third
light. This 200 watt LED from the 2016 era. And surprisingly, the Spider Farmer 100 watt
LED had HIGHER numbers than the 200 watt model! It was close, but the Spider Farmer pulled
out ahead. So yes, I would say you could replace a 250
watt model if it’s from 2016 or older. The problem is, many LED sellers give inaccurate
wattage specs! They might call their light 1000w and then
say that it only draws 200 or something much lower. These are false wattage specs. After posting my Amazon review, the seller
emailed me. Their product listing was referring to competitors
like that: Sellers who trick consumers by calling their light 1000 watt even though
it isn’t. I agree, the Spider Farmer LED could easily
replace many of those models. Just look at the actual wattage consumed and
ignore those fake wattages. Spider Farmer has now tweaked their listing
to make sure consumers aren’t deceived. (It’s nice to see an LED seller who has
some integrity.) So what specs should we look for in a listing? A good seller will list their micromole per
joule rating. Without that, it’s hard to compare LEDs even
when you get true wattage specs. Going further, look for PPFD or light intensity
maps. They should show more than just a center reading. Ideally, we would also see values at a few
distances. At a minimum, we should see spectral graphs,
efficacy ratings, and we absolutely need accurate wattage specs! No more of those made up, overinflated wattages! So what are my final thoughts about the Spider
Farmer SF-1000? I think it will be an excellent upgrade that
will fit perfectly in my small growing space. It’s a great option for lettuce and for nicely
sized seedlings over a 3 foot by 3 foot area. If you’re growing high end fruiting or blooming
plants like mari- TOMATOES, it could get you by with some entry level performance in a
2 foot by 2 foot area. But their listing also shows a two panel and
even FOUR panel version which would really get the job done for larger, high-end applications! The Spider Farmer brand seems to be new. So there might be concerns about support issues. But they offer several forms of contact info. With a 3 year warranty, they seem willing
to stand behind their product. Hopefully, this light will last a long time
and I won’t ever need to get in touch with them for ANY issues! I’d like to thank Spider Farmer for contacting
me. This is an UNPAID review. But I did get the light at a reduced cost. And I’m glad to say, thus far, I’m not disappointed! Check the description for a link to their
product on Amazon if this seems like a good choice for you. Thanks for taking time to watch. I hope this info has helped you out. Please subscribe if you haven’t already. And as always, Happy Gardening!

    I am growing a Maritomato Plant and I purchased on Ebay a "Colofocus 1200 Watt Full Spectrum LED Grow Light" But I know darn well it's not really 1200 Watts. I only paid $60 Bucks for it. But my question is will this light really be enough for my entire growth from start to finish by itself ? My autoflower is on Week 3 now and sometimes I worry that the Colofocus LED light isn't enough and I add a 2nd and some times even a 3rd light to the mix for a total of 3 different light shining on the plant to reassure it's getting all the light it needs to do it's thing. Not all LED Lights either. The Colofocus LED Grow Light and a Regular 300 Watt Light Bulb and a smaller screw in LED Grow Light all shining on it from different angles. Is this ok or should I only use 1 single light ? If so which light should I use ? If you could shed more info on the Colofocus 1200 Watt LED Grow Light for me that would be Awesome ?

    What is the expensive led u said the spider out performed?it wasn't an hlg was it?I'm waiting on an hlg 550v2 R spec to be delivered.

  7. JustMe UK Author

    I just dont why they insist on calling it a 1000 when it compares ( better and more efficient ill agree) to a 200 what HID and has a 2×2 footprint ( 3 x 3 at best ) that said its cheaper than any HLG product uses the same parts too… great light though

    Awesome video! I'm old school MH/HPS grower that has waited for the tech of the LEDs to mature. I think now is the time to try some LEDs. I'm a new subscriber as I just randomly found you and I liked the "Mari-Tomatoes" so much, I had to sub. Thank you! I learned quite a bit from your video.

    Costs you 5000 $ after 10 Years
    4 fixtures to get 750 µmol/(m²s)
    10 years later you have 50.000h
    50000h * 0,4kW = 20000kWh
    20000 kWh * 0,2 $/kWh= 4000 $
    4000 $ energy
    + 1000 $ fixtures

  10. Des420 Author

    Sadly, these lights have gone up in price by 15 dollars in two days… Which makes them less of a value. Also, the SF2000 is a better purchase than 2 units of the SF1000's, as they have almost 3x's the number of diodes.

  11. Juanitos Peppers Author

    nice video. getting people to look for ppfd and umol/j numbers when buying lights is great. Gotta mostly ignore the watts claim since it is often inaccurate.

  12. Matt Garver Author

    Al, you have some of the best reviews on YouTube. Thanks for the graphics, specifications, and clear understanding of grow lights. Going to miss that UFO, you had some great videos with it. Not too much though, since the Spider Farmer should provide you with some lower operating cost lighting to do even more indoor tests. Thanks for the video!

  13. laurie gallant Author

    this light is actually pretty amazing for newbies. 100 watt 2.7 umols/j is great. that means you can get 3 of these for a little over 400 bucks . geez the electric sky es 300 is 1000 bucks and and is only 2.3 umols/j . im glad to see qbs becoming more mainstream, and easy to buy for non do it yourselfers

  14. Roumen Spassov Author

    The product can't be shipped to my location in South Africa and therefore the price won't show on Amazon but I was wondering if you can tell me what the price is (in US$) so I can compare it to the Quantum Board I purchased. Thanks.

  15. I Own Me - You Own You Author

    With the 5000k diodes that light would be fantastic for maritomato seedlings and clones for at least their first month of life.

  16. Raymond Hunter Author

    Great video with accurate info for those of us who can't do the research ourselves! I just came across a company out of Chicago called Niemei LED. They have similar quantum boards with Samsung and Osram LED's and dimmable Meanwell drivers that claim 2.45 µmol/J. I would love to hear your thoughts to see if they stack up!

  17. Treshon Hayes Author

    If it’s for plants why would it include green wavelengths when they just bounce back anyway. Seems like it can get even more efficient. (I Barely know what I’m talking about just guessing)

  18. Just A. American Author

    Thanks for the information. I have been looking into grow lights to grow vegetables and herbs during the winter. I have room in the basement for a small growing space and lights are must. So now I have good info to work with.

  19. Sukhpreet Riyat Author

    Does it get too hot? Im thinking of getting this but I need a proper way to maintain the right temperature in the grow tent, would fans blowing on it be enough? Along with the intake/outake fans

    I've been seriously considering switching to LED and have been looking at the sf4000
    Are these lights good enough to replace 2 600w hps?.. in a 5×5
    There are no import cost to the UK, like If I bought an hlg 550 v2.. the delivery and import cost are enough to put you off.
    Many thanks for an honest and accurate review

  21. Gorb McNasty Author

    Hi Albo , great video..
    I'm trying to find out the PPFD or Umol/J of my LED but can't quite figure it out..
    It's a Kingbo 1000w LED (Only a budget one) that says it draws 200w from the wall
    First time grower of .. Tomatoes.. and just wondering if this is suitable or not 🙂

    Any help you can point me to so i can find out the PPFD orUmol/J
    Thanks 🙂

    Good to finally see cheaper knock offs of the HLG quantum boards. I have a pair, but i always like to see competition. Make them work harder for my money. Informative video, and 2,7 umol/J is a very decent spec, for competitive price. Anyways, on the site it says its dimmable, but couldnt see the dimmer knob. Is it on the underside of the ballast? It is on my ELG ballast and i hate it. I bought longer screws, and flipped it. I hope its somewhere accessible.
    EDIT: On second look, its not even that cheap. Its not expensive either. Its similarly priced.

  23. Derek Haggerty Author

    What they mean by 1000watt is the fact that its intensity of the LED is comparable to a 1000watt HPS or MH traditional indoor high intensity discharge lights . So really they are not claiming it uses 1000 actual watts at the the wall . 100 watts at the wall to replace 1000watts drastically reduces energy consumption. HPS uses 9.2 amps at the wall where a 100 watt LED only uses 0.72 amps. So you could literally use 12 of these quantum LED for the same draw (not sure if that's its actually amp draw but it's close) 1.2amps my 1000 watt Mars hydro LED uses. It claims to replace a 1000 HPS . Not quite but It's close though . I would say by eye it's as bright as a 600watt HPS. Either way the new LEDS are becoming a viable alternative to high intensity discharge grow lights. 10 years ago I wouldn't of touched these grow lights but they have come light years (excuse the pun)in brightness and reduced heat and power bills too. I have actually recommended the AGLEX 2000 WATT COB LED to a friend . It is actually brighter then the brightest 1000 HPS bulb ( hortilux by EYE ) which was been the industry leader for at least 15 years at least. I swear by these HPS bulbs. There is only one company that has comparable Lumans to Hortilux bulbs . So for a LED to be brighter at half the wattage, 400 watts the AGLEX uses . Is in my head and especially pocket book a viable alternative. The LED'S have finally made it to the big leagues. This is my opinion. I have be raising medical cannabis for over 20 years . So I would like to think my educated guesses have the experience and knowledge behind what I say . Good luck and grow organic food and medicine.

    Yeah I am using Logic V2 pucks from Growmau5. They are 100w puck boards using samsung diodes. They are insanely efficient. Incredible amount of light and they are passively cooled! LED tech has come so far. In my specific configuration they are at 2.3µmol/J (100w). But when run at lower power (63w) they can hit 2.73 µmol/J. I am using 3 but utilizing 4 at lower power gives you the better efficiency. Looks like these Spider Farmer lights are just as high quality.

  25. Majestic Vibes Author

    I love this review, for around 2 years! Ive had this cloud over my head around why do people always say 'watt pull from socket' is everything. But deep down i knew LEDs somewhat offer efficiency in this regard… but nobody wants to listen!!! Thank you for this vid. Im planning on getting the sf4000w for 6 plants only becaise they dont have 2 sf2000 in stock! Ive been doing so much online hunting. I think i can stop here and now 😁

  26. CocoTwisty Author

    Wow that Efficacy of 2.7 umol/J is pretty nutty… for comparison the Fluence Spydr v2.0 which is very popular with commercial cannabis growers is 2.5 umol/J!!!

    I'm brand new to grow lights, and am wanting to get the best 'Bang for my Buck' for a Tomato Hybridizing project. I am attempting to turn a San Marzano Redorta tomato from an Indeterminate to a Determinate cultivar with the same size fruits as the Indeterminate Parent. How would this light compare to a Mars Hydro TS 1000W?

  28. Ho Chimin Author

    Pretty much anything on amazon around 100-200w is a "1000w"
    i think what they're doing is basically :
    100w= low
    500w = medium
    1000w= bright

  29. Ho Chimin Author

    yea i just bought the 1000w grow light
    it runs from a usb charger
    10 amps from a cell phone charger is crazy
    so now my mini succulents will have a 1000w grow light
    lol may need to back it off to 8 feet from plants
    will double as living room heating
    and all this time I was using a 30lb 1000w transformer for my HPS lamps
    foolish me

  30. Ho Chimin Author

    you just wrote lol on the light i just bought lol
    i got it from a gift card at work for appreciation wk
    it will be lighting my 20' x 60' indoor grow house
    lol ya'll just jelly my 5 watt led desk lamp grow light does 1000 ppdf over the area of Wisconsin
