Exactly. "Regardless of cost". But, the poster I quoted mentioned cost specifically, so you grab it out of context. The point is, the tricks to make a COB LED based light efficient adding significantly to the cost doesn't make a quality HPS "cheap" or "low cost". It simply makes efficient cobs expensive. Don't think in extremes.
Yeah you are misreading it if you really think I "hate" LED or have any emotions towards it whatsoever. The answer to your question should be obvious by now. I really don't care to explain my reasons for posting. Call it trolling, that seems to be the general consensus
That sounds more like LEP. LEDs work nice to tune and complete a spectrum.
It's not being from NL that gives me an advantage, but being able to tap into knowledge from two leading countries in horticulture (in many ways, both cannabis and botany and horticulture research) does. And in case of NL where we use more electricity for artificial lighting than NY uses in two years for everything, efficiency is extremely important.
There's a lot more to it though. It's such a big thing in this sub forum because after years of hating on HPS making many false claims and acting like douchebags when someone questioned their 'believes' they have found a means of comparing that allows them to 'win' (read: grow epeen).
Just a couple of examples out of thousands...

Download and upload to google translate (dutch->english), and no that's not all HPS>LED, on the contrary. The first two are from a research center that does LED side by sides with budgets of tens to hundreds of thousands of euros, per plant species. No playing around, no LED bias, no intellectual dishonesty, no growing epeen.

No point to make, just pretty^
Although they will probably never admit it, at some point the white COB fans will realize they wasted time on so desperately trying to beat HPS. They are not nearly as innovative as they like to think, hooking up a few leds to a heatsink and driver... LED beating HPS luminous efficiency-wise has always been inevitable. The goal however is not to reduce electricity, it's to grow a certain amount of quality bud per year from a given space.
Me too. LED's the future. I find your expectations modest. But again, and this has upset certain members so those may want to close their eyes now: the efficiency numbers do not translate directly to the only type of efficiency that matters. Let me address that in my reply to your other post in the other thread...

While HPS growers focus on the G in GPW and LED growers focus on the W, we developed a light that addresses both weight and electricity usage, as well the third important factor: time. Using extensively tested light recipes designed by a team of photo biologists the cycle can be reduced with 1- 4 weeks. In many cases this results in being able to significantly increase the yield per year by doing an entire cycle extra.
Many of the LED designers targeting cannabis growers use COB lighting designed to be used in streetlights, billboards, shop displays, etc, and are not suitable for professional horticulture lighting applications.
Best of all, it’s nearly fully automatic. All you have to do is set the time and decide when to switch to the flowering schedule. Manual override is available and the light recipes can be easily adjusted using free software.

^^I sucked that light out of my thumb months ago... (though based on facts nonetheless, yes including the PM and Boytritis, based on actual side by side by actual pros) it's a Gavilips. Wanted to mind fuck you all cause I could create a photorealistic visualization and photoshop it above my plants.
Let's see your pics lol it's simple math. Lower heat less ac and less electricity equals more profit. I also forgot to mention the quality is better thus you can get more money for it lol
...........and you don't wanna start this conversation , trust me..Lol
