Gavita double ended...

I'd just like to point out that supra and church actually agreed that the gavita de fixture was a great lamp and that hps bulbs in general arethe benchmark to which all other hhorticulture lights are compared to. I'd also like to point out that they also did not insult anyone during the process and make major contributions to the community.

While sativied just rolls in here, bombs the thread and turns up the flames. While contributing nothing to the thread.

Eta. On a side note I've debated picking up a gavita replacement reflector to see if it would work nicely with some led lights.

I'd just like to point out also Gavita IS NOT the only player in the DE game anymore and as far as best that's debatable .
Im not going to lie. The epapillon de reflector looks awesome. Though I don't know how it compares # wise.

I know the infrared spike is not part of the umol count, never said it was. What I am saying, it is unwanted heat in my canopy.

3000K LED umol is better than HPS umol, I stand by that 100%. Simply because it is more evenly spread across the 400-700nm range.

I have no idea what you think it is that I am lying about. I don't really care either but since you are calling me a liar in public, here is your chance to enlighten us all. While we are calling names, I think you are ignorant, close minded, biased and rude :p

2.07 x 81% = 1.67

Perhaps you should add where you got that 81%...

Nothing more than debunked uninformed bullshit you are parroting from a user "Beta Test Team" who posted that in a thread at icmag about 7 weeks ago and is just a full of shit as you are. He clearly doesn't understand what he's reading, Petflora 3.0 (2.0 is for you).

I'm normally just joking when I use the word shill, but you are the real deal. All the blatant lies and HPS hating... what happened... someone stuck a DE bulb up your ass? Why do you deliberately spread false information that costs people money and possible a lot more than money alone....

I have no doubt the rest of your math is incorrect and inflated (a quick look at graphs from cree show at most 10lm per watt extra when running 500 instead of 800)...

You're tying together a few spots developed for streetlights, bill boards, roadsigns, shop displays... and pretend to understand horticulture lighting.... senile fungus gave me too much credit already when he tagged me but it's so easy and laughable to see what a bullshitter you are.

This thread should be renamed to Lies and Fairytales from LED shills and fanboys and rollie should add a forum for real horticulture lightning and make this a subforum for the micro/fluo/led grows... for the fire and healthy hazard diy kids to spread misinformation about HID lighting and inflate and hype LED.

COB lighting is just another cannabis forum hype. Professional horticulture lighting companies design their own lights and don't need to use COBs. COBs are LEDs for dummies, like the many unprofessional horticulture lighting companies who specifically target the cannabis grower. What better audience can you wish if you want to sell hype....

University of Utah considers Gavita fixtures the best. Thousands of growers who actually produce high quantities of high grade cannabis know they currently provide the best.

Can you out do that building your own LED lights... sure. Does it have a load of downside most growers will want to avoid, hell yes. As I've said before in these dumb discussions, I have nothing against LED, unlike you fanboys I don't involve emotions and don't derive self esteem from playing engineer or photo biologist. As most of us always agreed, LED is the future, at some point that future is now. If it were so great as the fanboys and shills claim here, why the hell do you need to spread such blatant lies about HID so desperately...

Gavita and popcorn and fluff and loss of terpenes... you're full of shit and clearly don't know what you are talking about.

Regardless of the supras .6%-1% error in his calculations(technically you're both wrong and it's 1.6767....but who counting)...he is correct and leds(only a very small percentage of them) are superior than hps. Both in output and spectrum(RQE). Everything else you are referring to is either price related or someone attempting to use substantially less wattage than the hps. Which is understandable...but that is companies and marketing...not the technology itself, which is what the core guys here in the led section are in support of...who ever/where ever it comes from as long as it's the best.
But on a sheer performance and output bases, watt for watt, leds are superior in every way. Now factor all the cost and problems sorting out true quality units...and hps is still in the argument.

Ironically, Beta Test Team is promoting the DE bulb over the commercial LEDS offered in the test and I agree with him. He is a stickler about using official test data only. He claims the data showing 19% reflector losses comes from a NIST certified lab and the test was performed using an integrating sphere. What do you have to contribute, a hunch? It does not reflect 96% of its PPF sorry!

You want to know what happened? I switched to COB and cut my power usage in half and doubled or tripled my yield. The 600 HPS setups I was using must have really sucked. There is no doubt in my mind that the 1000W DE bulbs are a huge step up from that, I promote DE all the time.

I have no doubt the rest of your math is incorrect and inflated (a quick look at graphs from cree show at most 10lm per watt extra when running 500 instead of 800)...
It is a 15.85 lm/W increase, as I stated. I counted the pixels in the droop and Vf graph. It appears your quick look math is wrong. You want to debate that? Take you 10 minutes to count the pixels, be my guest. I make lots of mistakes. I love it when people check my work.

The most efficient grow lamps in the world use COB LED. Big companies are not up to speed and that is understandable but we are on the cutting edge. You should build a COB veg lamp dip your toe in to our lies.

Apparently steep hill is full of shit too because Greengenes side by of Blue Dream cut under 1000W HPS vs LED shows terpenes missing from the HPS samples along with lower cannabinoids.

The bud pic you posted promoting HPS looks like janky fluff, maybe that is why you think 1.3gpw is easy. I prefer my HPS buds to look like this

Isn't that what the stealth and LED sections are generally? I don't see anyone using cobs to setup warehouse grows. It's mostly small setups. Mainstream Indoor growing implies HPS to me. You're already posting in a subgroup.


You're tying together a few spots developed for streetlights, bill boards, roadsigns, shop displays... and pretend to understand horticulture lighting.

HPS lamps were designed as street lights also. It took a while before indoor growing became accepted in the first place. "you're growing with street lights?" I can't understand that argument at all. That's how it all started! Agriculture is only a small segment of the HPS lighting industry and was never the intention.

LPS for street lamps. Also I'm seeing a lot of led used in the street lamp so does that take something from the led?

that's probably because most HPS reflectors in parking lots and security lights shoot 50% of the light into space and neighbors windows. Modern reflectors are fixing this, but cobs make it irrelevant.

Just ordered a commercial phantom de and demand is high. Its taking me three damn weeks to get the ballast. Got a ushio lamp and hydrofarm de hood thats optional sealed and air cooled.
I'm snatching them up as quick as they come in.
I've been converting all my setups to them. The 1000lh reflector with the agrosun 2100k bulb puts out a 4'x6' footprint. That's fucking bad ass. The other hood they make, puts out a more square footprint.
I just had to buy the components seperately, costs an extra 140 dollars each that way:-( , for two lights, because they are so hard to get rite now. Supposedly the problems with the ports is why they hard to get, over here in Cali.
1st picture is the 1000lh hood:

Goddamnit no wonder my ballast is taking 3 fucking weeks you hoard!

Street lights(led and hps) work great for growing.
The goal is to turn night into day...mission accomplished by streetlights.
Coincidentally plants like day.

Hps is still used in streetlights. As well as lps, and MH. But hps is still the most common.

At the end of the day neither were originally designed for horticulture...but they eventually were adopted because it was the best option available...then fine tuned towards horticulture after the industries adoption has already taken place.
