I am not sure why the light manufacturers are trying to stop the plants from stretching. Plants need to stretch a bit so there’s distance between the buds. Hate the new lights
I ❤️ smelly farts
Gorgeous fixture. These EVO mints are the truth.
I love all that blue.
Holy Keifer Sutherland that’s a crazy awesome PAR map for a 4×4. Nearly a 1000 and over in every space.
Why not try to dim and lower the light and find 1000 ppfd?
So this pulls as much electricity as hps? That makes no sense to me.
No 600 watt HPS is covering a 5×5 nor can it adequately cover a 4×4 either.
HPS is antiquated technology.
Hi buddy I’m in the UK wanting a good light this looks pretty amazing!
What light have you tested that’s similar to this one or better in the UK please
Hey What can you say to “SONLIPO SPC 2500W led grow light”? It is Qualität?
Buy. AMERICAN. Forget chinese made lights 👎
The lip smacking sound you make whenever you open your mouth to talk is absolutely maddening i hope me bringing attention to it makes you notice it yourself and you decide to work on unlearning that cause wow
Great review. What about real world efficacy ? How many watts are being pulled out of the wall between the two canopies at an average of 800-1000 ppfd ? As in ROi…✌️
680 watts
@Tim Page 680w? Which canopy? One fixture is going to pull more wattage than the other at a given (ppfd output) intensity. As in how many watts to get 600ppfd on both fixtures. That’s ROi✌️
@Doktor Hunggari it’s 1 light. He’s testing the 680 watt 6 bar fixture 1st in a 5×5 and then a 4×4. The watts is the same as it’s the same light. It don’t matter what space it’s in bub. At a 100% the light pulls 680 watts from the wall.
Im new to all this, ok so theres LM301H EVO and LM301H EVO Mint White? Is the Mint newer?
And then i know theres LM310B
Edit: or is “Mint White” a Mammoth thing and not a Samsung thing
Ok, just got this light and I’m gonna leave my first impression without actually using this on a grow to inform anyone looking at this light but having problems finding reviews like I was. So I’m not impressed! Lots of complaints so far. 1st – build quality is not great. It’s a little flimsy feeling, the rubber end caps are just glued with a dab of rubber glue and can be peeled back to the glue. 2nd- The hangers for it don’t lock in place in any way. They’re just hooked and resting on pegs and gravity holds them in place. It feels like if the light got bumped it could come off the hangers. 3rd- the rubber glue was all over the light and had I had to rub it off with my hand in multiple places (very unprofessional). 4th- the paperwork in the box is pathetic. Almost no effort. The only information on the light is a folded advertisement showing the par chart and a little info copied from their website. The instructions on anything related to setting up or using this light are almost non existent. It says basically “open box, put hangers on, plug power cords together, plug in wall.” No other paperwork in the box. I double checked cause I couldn’t believe that was all that was in there. For reference I have 3 other lights, an optic 720w, GC 680s, and a migro aray 4. This is the worst built light of the four I have. Opening this light and seeing the product that sells for this price made me want to start my own light company. I guess that’s what is expected when having it built in China but they could at least have it sent to the us for quality control or something. And the design is pretty cheap so that’s not china’s fault. Also one last thing, the box is a full advertisement for the company. It’s like a billboard. Not discreet at all. Bright colors on a black background. No cover of a plain cardboard box mammoth?!? My wife text me “did you get a new tv?” So if you don’t want to broadcast that you’re growing I’d be aware of this.
So the good about the light so far…..1- the led boards look nice and the light color spectrum looks nice. More of a bluish or crisp white compared to the GC. 2- the light output is bright. I don’t see myself needing anywhere near 100%.
I will try to come back and give an update after my first grow if I can remember. This thing better produce some great results after the lack of build quality and the lack of effort spent on quality control and design. If not this is not worth the money and there are better lights out there for less money. We’ll see.
Waiting to see the test on the new mammoth added green spectrum 680 mint white version 👀💪 even tho I already ordered it haha
Are these just regular lm301h diodes with less of a phosphorus coating? If thats the case, would going back to the old school blurple diodes be more efficient? LM301 diodes with no spectrum changing coating mixed with osram 660nm. Would that be even more efficient?
