Govita Pro dual ended super HPS?

Makes sense, Galaxy is Sun Light's own ballast. I believe in the first Govita vids I posted the dude talks about the importance/performance of the specific ballast and reflectors being designed for each other.
 
Interesting topic. I have always stuck with the hortilux 1000 bulbs. Hypothetically speaking if you were setting up a room and had the money would the gavita de be the way to go? For those wondering I am not in this position, it's just the best way to gage an answer in my opinion.

I believe DE bulbs for sure, but these uncooled one piece units like the Govita Pro will need headroom and a few feet clearance from your canopy.
 
The man. I am a little ignorant when it comes to this technology so I apologize for the basic questions. Do they make cooled de bulbs?

Sunlight Supply makes a cooled hood for DE bulbs that you can run without the glass. The numbers from that remote ballast setup beat the Govita Pro in the earlier mentioned testing.

Double ended lamps don't have much on a good setup with your typical e37 mogul.
I said not much because a good hid setup runs at high frequency, same as gavita.
A good hid setup runs low thd (this is where the double ended lamp shines a little better)
With a e37 mogul the electrodes have to run parallel to one another, the dual ended does not. This surely creates a more quality light but is it all that much better than conventional high freq ballast and e37 mogul. Slight edge is all there would be in my opinion but hey, I don't design lights for a living.

Well, I see a lot of commercial greenhouses not flowering high margin plants (like cannabis) using them. They must be somewhat economical.

I'm not an LED manufacturer. LED tech advances faster than computer tech.

Any lamp that mostly generates heat (and a little light) is doomed

I thought LED tech was really old. I haven't seen one LED light that can be hung vertically with any kind of efficiency, so I have my doubts. I haven't seen anyone crack the 2g/w mark with LEDs either. I think there are other lighting technologies that are going to end up taking over, but I don't think LED is the one.

i just read that article about phillips ???!?!?!? WTF... thats fucking retarded... one buyer.... harassed them..... so they quit selling to the whole Canna industry>!?!??! WTF? bull shit. phillips and gavita are in cahoots imo

Got a link to that?

I've seen some sick grows on the farm with these, but I'm not interested until they can go bare vert.

These have electrodes at both ends, correct? Not sure how you would go vertical without at least wires blocking some of the light.

Post #1305. 1.17 g/w under LED. http://rollitup.org/t/diy-led-cree-cxa3070.789575/page-66

Worth noting, at least.

With a 600w double ended ballast: https://www.opengrow.com/topic/48230-first-postit-could-be-a-good-one/page__st__220 (non vertical too, I also can't wait until it's possible to hang them vertically...)

Alright so here is the final number from the last run:

988 grams

Or roughly 35 ounces.

It exceeded any expectations that even I had. 1.65 GPW on full organics.

I think LEDs have a lot of inherent flaws in their design. It's directed light (first big one IMO as i'm a vert grower), and it requires different LEDs to hit different spectrums (which I think reduces their efficiency significantly in terms of watts to output). Plus they cost quite a bit on top of this. They do last a long time and they aren't totally uneconomical, but I have my doubts they will ever actually compete with good HPS lighting for the reasons I listed before.

Plus I have yet to see anyone hit the 2g+/w mark with LEDs. I have seen it with HPS bulbs, and not even these new ones which are significantly better (of course you can't hang them vertically YET, so once that's possible if it's possible you can expect huge numbers IMO).

I thought you might like that thread anyway as the guy is an organic pimp like yourself.

Same way my Reptiglow t7's have a double ended setup would be my guess. But even if you have some blockage it will still end up being more efficient.
 
IMHO, it'll all be LED. The tech is advancing way too fast and that's where every lighting company is investing. When you're illuminating buildings and parking lots with it, canopy penetration isn't an issue.

I can't get behind a lighting product when most of its output is heat, not light. Inherently that's a problem.
