bahahahahahah less than that.

Ya I think supra is getting at this i sjust one point in testing, we are being scientists in a slow lab, so testing is always an on going thing. Any gain in efficinecy is worht note as it could help grow more. I was looking at lenses due to canopy penetration. I would say grow method is...

@SupraSPL I see that you ran a test with the lens, Just want to clarify the results. lenses, at this juncture in testing, provide a SIGNIFICANT increase to the diy reflectors you tried. Is that right? I Would like to see it vs the angelina xw. But if the lens 200-300% im not sure if itll be a...

SO many Diy threads. @rootney Yes, not running the droiver at full capacity does have an affect on efficiency, eg 92% for not being at full load all the way down to 89%, They were helping me and answered that one, so I thought Id share. I am ganna get the new cxb and use the hlg 120h-1050 and...

Lol Im so stoked. The fans you posted have a rail mount on the side, So I can just add them to a rail as a temp mount as I mess around.looking for 3 ft rail now. with current designs not quite the best reflective material but it would work till I can make a caseing for it. I do need a driver...

Sick there is some good info here and some good info for the thread. I was wondering about the 36v too. I AM SURE THEY WILL BE RELEASED SOON AFTER. I believe they would have had to test the bins to put out the press release and data sheets. by all means DO NOT ACT LIKE ME and just buy it cause...

Yea same guy, the multi strains are an issue when it comes to nutes. Gotta pheno hunt though.

CXB3590 CB X4 $240 Alpine11X4 $40 .7A driver HLG-185H-C700 $70 total cost $350 195.6W @ 51.7% = 101 PAR W $3.46/PAR W @SupraSPL I will be going with this model. since you stated the 1050 driver would be hitting some limit. I am not sure what limit it was. I will be doing this cxb x6. I would...

As of now just over 20 for sale of the 72v class of 3590 on digikey for the mar 11 delivery and next delivery will be coming first week or 2 of april I saw. SO there is limitied availability for now of the Cb bin. as others release the prices and calculations will change.

But when it comes to choosing between something like Vero29 running hard versus CXA running soft, the increase in efficiency is not as extreme as when switching from HPS. That is why I recommend most growers run their CXA3070s and CXB3590s at 50W each. Here is how it compares: Vero 29 running...

I pumped an 8k quote to determin the stock at digi, and they get first stoock on 3-11, and second stock is like first week of april. I did however look at lead time when numbers were input, and it stated only 26 more left in stock for 3-11 shipment. Just wanted to share, incase you were on the...

@Scotch089 you know more about this then I Do, by no means am I saying ur wrong. I was agreeing, that if they can scew their data using higher amounts of blues, or really any color past usable spectrum it becomes wasted energy and is a means of scewing umols reading(totally understand that. I...

@REALSTYLES The cobs in ur pic are sick looking man. Glad to hear you like em 2.

@Scotch089 for sure man, those are way up to par when it is compared to commercial fixtures. Ive seen some commercial lights hit that at 24" on outter limits, but your stating this is a bit of a falsified, or scewed, result due to measuring methods. Understood. Thats still legit that we learn...

The curve of the veros lean towards higher current(or amps) being more efficient, and the cxa have the reverse curve.more efficient at lower current, they are most efficient running at lower watts or Amps x volts. So it isnt always the scenario you stated, just on the cxa model.

You cant really change the resistance of the led, the controllable factors are amps and votls nusing the driver to make watts/ per led. so ignore the resistance. you would say the more efficient it is, the less resistance it would have. well the less current, the less resistance of the led ( idk...

I dotn wnat to end up with shield payback like the mars. I am just thinking the extra lumens will really help the coverage area and fruit production and wont hit any heat watts or any o limits. if this hypothosis is wrong then I believe the best would still be the 700 I am a bit worried about...

Okay cool. what I was sayin was your umol rating was not through your canopy? I assumed you measured from the light the build? it is really irrelevant mines ganna be pumped a lil different and newer light. I Was saying that 200 umols is hitting the bottom what you really want so the livable...

I mean that 200umol at 18 in with a 6 in gap between light and canopy and 12 in deep cannopy is a very constricting limit for such a wide area. IF the beams werent degreed so widly (eg.180 panel and 115degree single lense ). wed get the photons to angle more directly to the canopy. I am pretty...

Le git lol ill post a pic for all your help, how could I not :D is that just a white backround for a reflector?
