what are you yielding???

[spacebomb]

so. theres no diff in the flow rate of the electric?. hmm?

dude come on............. doubling yield ????? the way the electric flows??????

please dont just believe what some guy in a bar tells you and do some educated research, you sound young and easily influenced

they are great lights, i have 10............ but they are just lights. they dont double yield and they dont change electric flow....... wow !!!!!!!!!!!!

 

[spacebomb]

well ive got a big bowl that fits but !still i rearly weigh it up:-). i know ,i should.BUT i know ,roughly,.ill start being more detailed + keep weights.
s-

the curiosity would kill me i would still weigh it under the little scale add a plastic lid to top of scale and deduct the weight ... just me thou but i def wanna know my harvest weight...

hey,come on people.im not extoling anything+ i dont understand electricity.im.not here to tiff man guys.i was simply making a point,observation.

the def of the word extolling means to elevated or raise , simple put he was stating that you are elevating the lights to be greater than they are , and then he explained the lights performance or expected performance , in closing stating that final outcomes are also grower induced

I have seen and held those de bulbs and based on the technology I saw it is probably good for maybe a few months longer then a standard hps bulb.of course the boys at gavita will tell us how efficient and great they r but I dont reallysee it in the grows.guys that are buying them are already killin it and knew how to set up a room beforehand. All the best grows I see and read about on the net are always running bare bulbs vertical, ballast and bulb brands never seem to matter.

I gotta say I been weighing my harvests alot more since I started reading at this site based on some of the ridiculous claims I see lol.if you focus on quality the yields will be there. Dont be bummed if your only hitting .5 gpw if everyone likes your smoke.its so strain dependant I dont even worry about it anymore.i have a spot I know puts out 1gpw with my masterkush, and I toss a sativa under that spot and im lucky to hit.5.

I'm sorry, Spacebomb! I did not mean to sound at all snarky, I was just saying that while you may not fully understand the terms you're using, you did hear correctly that the Gavita (and now others') double ended 1kW HPS system outputs roughly twice the lumens as conventional lighting on the old ANSI S52 standard does.

The new standard calls for operating voltage- what the bulb sees- of 400V, compared to 250V for the old standard. This, plus a more compact bulb that runs hotter, succeeds in making a better light that doesn't suffer from lumen depreciation significantly throughout an expected three year life span. If you want to light a sizeable growing space with HPS from above, this is the proper tool for the job.

To extol something is definitely to sing its praises, but does not itself imply exaggeration.

Ty are you saying the ballast is turning 240 volts into 400volts at the bulb? I believe those figures are for cold striking the bulb to light it, not constant volts right?

If you don't believe the claims of bulb life, go ask your buddy running these lights how his plants look once the bulb is in its second or even third full year of use. If he says he can't tell the difference, go buy one for yourself, because he just proved the claim.

ANSI S52 calls for raising input voltage of 110, 120, 208, 220, or 240V to 250V. Amps fall, but that's the ballast's job. Striking the bulb requires the use of a capacitor to induce the electric arc to strike the bulb, but it runs that line voltage the whole time the bulb runs. It only reaches full amperage when the bulb fully warms up and is producing maximum lumens, about 10-15 minutes after ignition.

Line voltage for the DE bulbs is up to 400V, still from the same 240V outlet. What may not be obvious from a visual inspection is that the physically smaller size allows engineers to maintain a tighter temperature gradient which improves efficiency. This is why these bulbs are not rated for vertical use; they would run too cool, hurting spectrum and efficiency.

The smaller glass envelope around the element also aids temperature stability and thus helps lifespan. The dramatic improvement in lifespan was definitely one of the design goals, as I'm sure they were aware how much it sucks to change bulbs every 6 months!

that sounds like it came right off the gavita salesmans tongue lol.are you saying that ballast turns 240 volts into 400volts constant? if so we should be using that tech to make more power from power and lower our power billso_O

sounds like my neighbor who came to me (because I am a Mech designer) with the idea of pumping water to a barrel at his roof to be able to use the water to power a turbine...... to power his pump to pump the water to the barrel to a power the turbine to ........

I patented a perpetual motion machine years ago ..... where did I put that patent anyway?

Watts, or useful work = volts x amps

It doesn't create anything. When voltage goes up, amps come down, all a ballast does is change the ratio of v and a in the equation above, while keeping watts constant.

gotcha ..... true dat.

Oh ok .im .only saying what i read.

yeah,now i understand:-)thanks man.thaught you were bashing me up to:(hahaha.lol.i DONT exactlly understand them terms ur rite,.im ere to learn.+share what i know.soo i was basikilly right? they run 400,v,s? in uk its only 120 ,i think.its double that in the u.s.. im not a smarty pants ,BUT i mean im no idiot.i can crack on with the best of them man:-).lol
peace man.

Your good but im still not convinced they are getting more than 1000 watts out of that 1000 watt bulb ;) what r they claiming for lumens anyhow? Its been a while since I watched that vid someone posted here from the trade show.i was gunna pull the trigger on a pair of 600 untill I realized they use the same bulbs im running basically.

Here is a quote from Jacks thread at the other site:
Th yield was pretty equal with the 4 adjusto wings and the 3 Gavitas .. But the single Gavita vs single Adjusto wing over the cookies was almost 3 times the yield...Doing a bunch more testing im not ditching the Adjusto wings just yet but if I built a new room it would be all Gavita or Phillips E Papillon..


You have to take into consideration that he his not even using the Gavita's in there most efficient manner. Gavita 1k's can properly light
up a 5x5 area and jack is using them in 4x8's. It depends on your grow style but, using two per 5x10 bed you can get roughly 60 more
plants into a 5x10 sog bed then a 4x8 sog bed. Getting a 70 to 80% increase is not crazy talk.

 

[Moe Lasses]

just skimmed the thread, not sure if its already been addressed... but...

we've always measured yield: grams per watt/30 days flower

ie .5 gram per watt, 30 days= 1 g per watt 60 days

same over all math just more detailed/useful info... strain equalizer

I have seen gavitas increase GPW significantly over standard bulbs,dont know the exact science behind it but it works.My buddy recently ran 2 tents one with a gavita and one with an AAW,dried weight after harvest was 418 grams for the AAW and something like 460 grams for the gavita,Not a big difference until you consider the gavita was a 600 and the aaw was a 1000!

Imagine what he would of pulled with the 1000w Gavita

Was he using the Pro fixture or Plasma?

The ballast are 240v and powers up to a 400v 1000w bulb
