What's your take on the ultimate LED growlight?
...
Tell them what you want, and they might build it
I want one that reads the plants and automatically generates the perfect spectrum at the perfect intensity for maximum growth and yield in the current growing conditions. 
Well, you asked
And what would you be willing to pay for this sci-fi lamp ?
Safety first it’s got to be safe and reliable.
Performance second, there is a lot of great lighting options and something perfect would need to be better.
Cost including energy savings third, if it’s perfect it can have a higher initial cost but needs to be more energy efficient than other lights to justify that cost.
Built in features fourth, dimming and things like power switches (why don’t lights come with switches?). I don’t want anything inconvenient about a perfect light.
Gimmicks last, WiFi and built in timers that simulate sunrise and sunset are fun. Maybe if you could customize lighting profiles, so you could for instance have a 16 week Sativa profile that differs from an 8 week Indica profile. It should be easy to add and remove additional lights that automatically use these profiles. Maybe since it’s already got WiFi it could have built in sensors for the environment like humidity and temperature displaying on a nice interface on your phone or computer.
I don’t know I’m high but those sound like good things to me.
I have an expensive Timber light, I’m not cutting anything on it. The driver, timer, and power strip are all outside my tent between the tent and wall so it’s not very convenient to turn it off. The dimmer is accessible so I just turn it down to 10% or whatever when I’m working in the tent.

Is that in addition to 'white' light, or do you want total spectrum control?
In a perfect world, total spectrum control. Most companies aren’t there yet, so you have to settle (for now) with two dimmers - one for blue spectrum ranges traditionally associated with veg and one for red spectrum ranges traditionally associated with flower. A lot of companies already have IR baked into the red/ flower side and are now starting to introduce targeted UVA as well. My perfect light would be liquid cooled and have about 8 dimmers
Thanks for the feedback
Dimming to off is not possible with many drivers.
I'm sorry to say that you're in the danger-zone of being scammed...
Would you really rather want a fully tuneable lamp with mono diodes from 1979, than a simple output dimmable lamp with diodes from 2019?
We would need to know how to use the spectrum for each phenotype at different stages of its lifecycle or indeed designed to each daily cycle.
Nobody knows how these spectral changes affects cannabis plants, especially not when the plants are receiving 1000 PPFD, so we'd just be turning the knobs blindly...
The spectrum is less important as the intensity increases and it's easy to supplement the high efficiency white light LEDs with specific colors.
In my opinion it's a good idea to not let oneself get to enchanted by the promise of spectral control(YET!)
When we know more about light and plants in general we might find more of those instances where certain wavelengths at certain times give us a desirable effect, like using 730nm for an hour at the end of the day and 15 minutes into the dark cycle will shorten flowering time.
The more we know the more interesting control becomes, but at this point in time assuming personal control of the entire spectral output is like herding cats
Thanks for pitching in

And we are trying to work on our lights to achieve this better and better. 
I agree with you. I have an 1100k deep-far red cob. I turn mine on for about 30min before lights out and 30 after lights on. I've seen no difference in flowering times whatsoever.
