Yeah but how would you lay out all those strips i cant see them fitting in or any good driver solutions. Remember im doing 4 strips in series, youd need to go down to 24 but then how would you lay that out in a sensible way with 6 string of 4? Just check the pics if youve found them, where does...

Estimated and at board level. And to 2.7 not 7 but assuming its a typo. And remember this would be at full power, drop down to 200w it would be 250mA per channel with both channels on. Now i cant remember if its 12 or 14 parallel strings per side but that means each diode is getting 20 or less...

Not to mention that most people see the price and think its USD when its the relatively light weight Ozzie-g'day-mate dollar. We went for those fancy t-slot heat sinks which are very nice but a bit more pricey. But for bigger builds they can be sourced on Alis-blubber for discount (though i...

Does anyone know if you can get EVOs without phosphor in any way? Only 437nm blues? Id love to add some blue but not keen on all that green...

There are a few threads on misshapps with a few of the low-mid range light brands but i dont wanna slam any of our sponsors so do some research, google may be easier for searching just add rollitup to your search term. Havent seen this light up properly but afaik the quick connectors can be a...

I dont know if were talking past eachother. My argument is that lenses will not increase penetration, just that and if you "measure" P with how many buds you get on lowers youre barking up the wrong tree. I actually agree with most of what you say in this last comment :) what youre talking about...

For gen 3 tests go check the other thread mentioned, id expect the 4k 80cri to be about 10% more efficient in ppf/photons than 2700k 90cri tested.

Let me get back to you guys, but it would help to know what is the size on ur build SWS? Theres info in the vesta test thread, it may be easeorr to find using google "vesta test rollitup", and also some info in "bridgelux gen3 rollitup"

2 strings of 4 strips per 150 driver, each at 700mA, but since theres 2 channels per strip it works out as 4 strings when you have both channels on at the same time. That should give approx 2.6-7ish ppf per w, 2.4 if only one spectrum activated. Refer to vesta test thread for the tests :)

Check my posting history for pics of my vesta light, it was posted a day or two ago and im too on the go to look up the pics and have been bandying this light maybe a bit too much. It would be pretty much perfect for a 3x3 at about 300 watts but its somewhat over engineered and could be a bit...

First no probs with English, please excuse my fast typing with all the spelling errors. I recently wrote "let the food times roll" instead of good and couldnt edit it out. To me working with strips has become somewhat of a nuisance, especially the blux since they tend to be very low watts per...

Id like to say sorry if im.abrasive, not really my intention. I think my keenness to argue here stems from a long history of arguing with growbro arguments about P which is really frustrating; its generally met with arguments that tend towards "feels like/looks like" with little rational content...

Yes, but even so the "penetration" as in bud formation deep into the cannopy is fairly independant of the light levels that hit the lower bud. As ive stated even in low light conditions of buds 40-50cm down; we can get nice hard bud at about 50ppfd as long as weve done the plant management well...

Maybe youre looking at your own posts? Maybe youve not made enough posts?

If working out a series/parallel wiring scheme it helps to use some kind of constant power driver, meanwells range us xlg but not the best due to size of driver in a good voltage range. The reason why is the slightly odd voltage which doesnt work well with any cv driver unless youre fine with...

Without backing its going to be a disappointing and frustrating experience. These strips are like bent straight out of the box. The side with traces and diodes is more rigid than the the other side, so it kind of bends the two ends upwards. Sincerely, go for regs. Also they get hotter than you...

Dude, dont, dont use that driver please. Its over 400V, those BLux connectors are not rated for that. I think their rating is like 60V but i know for a fact they can manage a bit more. But not 400, also for your own safety. The way to do this safely, if youre married with the idea of series...

Dude, just get a ppfd meter down the cannopy of your grow with lenses and youll see what im talking about. Behind the leaf theres shadow. Doesnt matter how you shape the light before it hits the leaf, behind the leaf theres shadow. If youre growing like this you could easily show me penetration...

No matter what you do with cobs and lenses, 3-4 leaves deep into the cannopy there is not enough light for the light down cannopy to really be driving bud formation. Buds all the way down as a function of light is a myth imho; ive seen solid 5g nugs growing low in about 50ppfd environment. If i...

Ots a good work around but as is will only work on one dimension, depth or width. For a perfectly square space you a bit stuck unless you make a square/frame like thing, something like this: This actually have a another spread even feature, the perimeter has separate dimming, double driver...
