Got a source for this claim that 95 cri is better than 90 or 80? With 90 CRI you are already peaking at 620-630nm so going higher only results in losses to the extra phosphor, and a slightly deeper red peak; not any more photosynthetic benefit. Due to the way chlorophyll becomes saturated and the interaction green light has on green leaf, it should actually be more electrically and photosynthetically efficient to use blue light and make green/yellow photons than a heavier filter with less PAR overall but more red.
Hi CRI and spectrum efficiency are the main reasons why cmh outperforms hps at less intensity and wattage. If you've grown with blurple, cmh, hps, mh, standard and enhanced cob spectrum, the advantages of high cri and spectrum efficiency will be quite evident. Notice how cmh contains low blue, peaking in green and red spectrum. The McCree Curve also shows plants need more green, yellow and red compared to blue, peaking higher in those spectrum respectively. This is why hps, which peaks in the yellow and green is still very effective due to the high-intensity that increase it's efficiency to a point that it can match and replace the 660nm. Many plants absorb as much as 98% of the green spectrum. All this info are available if you dig deeper past the industry myths and psuedo-science that are based on ignorance and misinterpretation of facts.
For some reason it will not allow uploading of files now so please refer to the link below for the cmh spectrum.

XPG3's are not as cost effective as a good COB. 11$ for CLU048-1212-F1, matches CXB3590.
The have pretty much the same lm/watt and efficiency as the COBs. Yes, the Citizen's more efficient, but can't be push as high as the 3590. You obviously have not experience the 3590@80%. Not interested in gas milage here, I wanna haul ass within safe parameters and get the most of what I got under the hood sir. Would you drive a 600hp+ Lambo or favorite rocketship at 55mph so u can get the best milage?
Why do you think so? How do dimmers magically solve the efficiency race? Timber kits already come with dimming so this is a moot point.
It lowers the current to appeal to the conservative DIY minded "efficient" growers and eliminates the issue of them over-driving.
They use PARw. Many agree that this is an acceptable metric.
Side by side to determine net ppfd, growth and most important yield will determine realized efficiency where it matters. Anything less, it pure assumption and speculation. More interested in net hp at the wheels, not bhp. Not interested in academic efficiency. Claims are useless bs without proof. Line them up for pink slips makes it more interesting and credible.
Timber kits use passive cooling which will always run hotter than active cooling. Case temperatures are not the metric we should be using to compare two fixtures. Do you have a link to the grow where he talks about DIY not keeping up with Amare?
Great, we actually agree on something
Wish the other on the so-called panel of LED experts is as knowledgeable as u and get their facts straight to make their bashing and bs more convincing. You can hit him up yourself to get the truth as he's the only one quality to have a definitive answer on this matter since he actually used them both. Case temperature or actual operating temps determines the LED efficiency and reliability.
Nobody is calling him a shill because he doesn't show up in every single thread shilling for Amare.
Demonizing and bashing a product just because of personal reasons and prejudice are unethical and selfish, especially when new inexperience growers actually rely on some of these recommendations to base their purchase decisions on. Why is it the ppl who recommend timber or other companies not shills and the ones who actually own amares who share their grow results and experience are labeled as shills and trolls?
Neither COBs nor Meanwells have any meaningful fault rates so having one driver per COB simply adds to the cost of the final product.
This is an not a wise assumption, all electronic components will have a failure rate, regardless of quality. Unlike hobbyist and personal growers who use limited numbers vs. commercial growers who are at risk due to their volume and are very concern about reducing possible failures.
Is this before or after we apply some 25% discounts that only a small percentage of people know about?
Another assumption with no proof. I'm sure even the gentlemen who said they stated that the -25% is not available on the site received the offer as anyone who contacts them direct. They also offer discounts on other forum as well which I will not mention since it doesn't pertain to riu. This is due to the fact that they also have to support their dealer/distributor network. What's important is the actual market price, which most who have purchased will confirm they received substantially lower pricing than their msrp. This is a lot better than all of the current premium cob offerings.
Timber kits will be cheaper unless Amare ditches the monos, upgrades to newer chips and switches to a lower-production cost fixture. They could always introduce a new coupon for 50% off or worst case, lay off some shillmen.
It's a matter of preference on the monos. Like anything, some will embrace, while others reject. They are the lowest if compared apples to apples with the components and will more than likely be lowest with the new cheaper chips. Rumors they are working new models that will be avail soon. The marginal difference in efficiency is more than made up with the higher current and lenses. Again, running a 6 liter V12 at 5500rpm will not get you the best efficiency and gas milage, but will sure develop a lot more power and achieve it's full potential. (promised no more car anology after this) The question is if the extra gas consumption and loss of efficiency is worth it and that depends on the individual. If you have dealt with them, they do not offer free panels nor require favorable reviews. Most companies, if not all, will have some kind of special journal pricing. You and others recommend timber and other riu based advertisers. Does this make you a shill or troll?
Until then, if anyone asks for the best deal on a good LED light, the answer will be DIY, followed by Timber. 50% efficient at a reasonable price and they don't need fucking coupons to get people to buy them.
