I have lights designed and built that run Vero 29s at 100W each. They work great no problems. However, all costs being equal, assuming similar canopy intensity, by adjusting distance from light, I think a 3 Vero 29 light at like 2ft would lose to a 6 vero 29 light at 1ft in terms of yield.Or even just run your existing 3590's @ 100 watts. The light company I prefer to use is doing this & still standing behind a 5 year warranty. If they can do it, I don't see why a DIY'r can't when they replace their cobs every time the newest, baddest cob or tech comes out anyways?
But I am shunned for suggesting it?
I brought this up in an led vs. HPS intensity thread that shows a huge drop in led under the canopy. The high powered LEDs did not have much drop nor did the HPS. But I'm an idiot right?
Everyone complains about the drop. I come up with a POSSIBLE solution & I'm dogged by guys that don't even grow. That's why I bugged. Not because I am right or wrong but because NG's talk mad shit to people trying to contribute to bigger buds & larger yields.
I don't get it, why????
So underpowered, underlit tents can be promoted in order to sell lights for vendors?
I don't know but that's what it seams like seeing how the guys saying I'm so stupid appear to be hype men, not growers or smart people.
Also worth noting, I have a PAR meter, and everyone should know in most cases they are sampling a 2 dimensional plane. So orientation will effect measurement, an important consideration when you are dealing with multipoint sources of light and highly reflective walls. Just taking a few 1ft spaced out horizontally oriented measurements in given space is not an incredibly effective measurement, I can get a 50-100 PAR change by simply tilting measurement plain at some locations. To accurately measure you would need to take much more precise measurements, maybe like 4-8 per ft to account for angular dispersion.
I think there is something to be said for spreading out the COBs and distributing the light, but I think it is more important to consider the cost metrics, and planned obsolescence of the COB its self. Makes much more sense to drive the COBs hard for 2-3 years, simple math. I could build a 300 watt 3 Vero 29 light $300, or I could build a 15% more efficient 300 watt 6 Vero 29 light $450. Now simply apply the Gen 7 Vero 29s and my $450 light is obsolete, and I could simply replace the COBs in the $300 watt light for $75.
