New roi-e720 available in few days. Would this be a better upgrade from 1000w se hps?

I'd have to say that a person might get curious about looking into the light to see what makes it tick. The screws are standard phillips so if a person wanted to crack one open they could. I for one have texted the company to try to learn exactly who makes the LED's and model information as well as what type of driver or drivers they are running in it. Again I'm got to say that the construction from what I know looks really good, but that said I'm only talking about the outside of the light only. Curious has anyone gotten ahold of one of the new HLG Sabor bar lights? I saw a add for one recently and they look interesting, again likely only gonna be of interest to a person who isn't entirely comfortable building their own lights. More power to the people that do but for now I'm not gonna venture down another hole when I still haven't made it out of the one I'm currently exploring. Maybe someday I will be able to afford a room with lights covering the entire room which all could be controlled independently alone with built in environmental controls and other bells and whistles till then I'm happy just learning what type of light I find works best for the growing I'm doing.

How far away is the light? I have mine almost on top of the canopy no bleaching or heat stress. They're on week 4 now will post harvest when ready

yeah, that's not good imo. I have my 680 at 18" from the canopy and it's still dropping 1200+ from that distance vs the e720 that has to be within 6" and then only in some spots does it reach 1200. The fact that grower's Choice advertises these with "boost" which they even admit does not exist in the e720 tells you what kind of integrity Grower's Choice has.

many updates with the 720s?Did the problem get resolved and if you did exchange the lightshow are they performing now?

Thanks in advance.

Is this light worth the money? Before I spend 2k and regret it

I can buy these for 900 dollars at my local grow shop.. they are worth every penny from what I’m told. I have experience with similar led lights and I can vouch they are great for veg and bloom. This is a great unit the e720 because it includes The cables required for one 240 V and has a dimmer knob built onto it where the Gavita you have to buy that stuff separately.

2159 ppfd with 700w? 3.1 efficacy?

I dont think thats realistic at this point in time. If the Fluences and HLGs of the world are getting 2.7 or 2.8 with all their resources and top bin diodes with contracts from Osram and Samsung. How is this company dumpstering them with a 3.1 efficacy rating? Sounds bogus.

edit: I also just saw its 1752 diodes. The Gavita claims 3300 diodes. Hows it going to put out more light than the Gavita with half the diodes.

Growers Choice ROI-E720 is hands down the best value Commercial LED light out there that I know of. I have many clients that have used them and attained as much as 3 pounds under 1 light with 2 plants.. Gavita 1700e was top of the line but they don't include the dimmer or power cords you have to buy that on top of the lights which adds up quick not to mention they're more expensive to begin with.

The 8 bar folding fixture (not the one with UV) has 2880 diodes not 1752

But I didn't say anything about an advertiser. Only about Calvin being an obvious shill for growers choice...

Even though you had the light on at the beginning of the video after cutting them off you have to wait about 5 minutes until it's back to full power

I have 6 of them and they do boost but not with my trolmaster I had to get a growers choice controller. The boost setting is on the light it self. I produce 3+ on each and have run them a couple grows now and am switching from 12 phantom 1000 de to 12 e720s. Picture is end of week 5.

I have never liked led but the side by side convinced me to I went from a 2k + electric bill to 15-1600 a month by switching 6 out.

I just pulled down 2 lbs with 4 plants in 6 gallon autopots of coco/perlite with Botanicare CNS17 base nutrients under 1 GC ROI-E720 light running @ 720 watts with about a 6" distance from canopy as they suggested. As a previous commenter mentioned he's doing I'm doing the same, replacing 1150w Gavita DE HPS with these fixtures. I get them for $800 cash.

When the guy at my grow shop told me that this LED Fixture would get me at least 1 pound even that sounded like bullsh*t, it's not.. These walk all over the HPS and are beautifully built.

Pros: Less Heat, Less supports (stakes/netting/yoyos etc.), Less energy consumption (both from less heat & less actual watts), Less Power Draw (Almost 2 amps less than 1000 W DE HPS @ 720W)..

You legit just can't go wrong.

Another thing I noticed with the LED is I do not need more than a couple stakes to support the plants even with quarter ounce colas hanging off the plants. With HPS plants like to flop over because of the lack of blue spectrum whereas with LED this doesn't happen. I don't even need to use scrog netting with my grows now. Unexpected bonus and something they don't advertise which I think is actually a good selling point. I'm sure it's strain dependent though..

Don't worry, happens to me all of the time.

I just bought one these a couple of weeks ago. Fixing to flip to 12/12 in the next couple of days. so far so good. Also got everything in from Greengenes {PLC} and will build that light this week. I'm ready to see which will do the best.

newbplantgrower420 said:

oh wow they came out with a more powerful one. i thought it was just the ROI E420 they came out with.

this should put out more light than a SE HPS for sure.

Should actually put out as much as a 1kw DE HPS.... if its true what it says 2080umols.

I might try getting 2 of these on my 4x8 and putting it side to side with the other LED bar lights I have coming to compare them. These guys have the best price outside of Alibaba for LEDs.

This is the 680

Barristan Whitebeard said:

The "boost" mode of the ROI-E720 light lifts the wattage draw from 720 to 800 watts and the PPF from 1850 to 2050 μmol/second (further down the OP's linked sales page PPF output is listed as 1870-2080 μmol/second, so seems like there's a small discrepancy there) while still maintaining a system efficacy of 2.56-2.57 μmol/joule (according to Grower's Choice). Depending on a few factors, that seems well within the realm of possibility.

And where is the boost mode switch?? Hahahah
