Not sure how you explain the giant shiny fixtures on your roof/yard. You could even have tracking software, tracking the sunlight...pipe the fiber-optics into your grow room. I am sure the neighbors won't noticeHoly Moly

Salutations WVTurtle,
Time to pop, that's still a relevant topic IMO.
The suggestion pleased me instantly because the number of interconnections in LED lamps is one major drawback as far as i'm concerned: it's calling for failure unless the thing was built to travel in space, euh... Oh well, i like to exagerate sometimes, and yet one of those cheap LED lamps i got at a local store didn't serve the anounced MTBF. Not the least bit. It was practically Dead On Arrival, euh... Mechanical problem for sure, it's made in a far away poor country, etc. In any case it failed early. So, how about restricted market products?...
It's that line of thought which makes me somewhat more optimistic about induction lamps that just got no electrical contacts to fail at all. It's wireless by definition. Light flux may need to improve though.
In the meantime i was thinking maybe we should use distributed LEDs assembled in grapes that fit a plant's peripheral profile closer, for better "penetration". Self-cooling suports shaped like arms, elbows and fingers would be fed with cold water to evacuate heat before it enters the cultivation space, etc. A bit involving in the end...
So what i like with the idea of LASERs is that it can be installed away from the plant and yet it would hardly cause concern in terms of penetration i suppose. Now imagine if it could scan each green leaves at such high speed the vegetal organism won't know the difference with continuous light... Blue & red LASER pairs would be the minimum setup i believe, it's because the ionic pump in light-assimilating molecules work their wonders in steps and hence some colors actually correspond to twin peaks (illustrated below):
A couple years ago i didn't read about Chlorophyll "f", with the carotenoïds the amount of color peaks has raised to 7 then!...
So, that's 7 LASERs per lamp and i'd want at least 3 units circling a plant, illuminating it from all sides with a CFL on top to get nice pictures perhaps.
Anyway, a 7-channel LASER scanner in 1 lamp and i need 3 lamps for 1 plant, 4 for 2 or 5 for 3 - plus a CFL bulb. This could sound a bit prohibitive, hummm...
Now how about 1 central 7-ch LASER scanner aiming for mirrors on the walls all around a plant instead of its vegetal surface itself?...
Even with twice the distance a beam of LASER light wouldn't weaken significantly in my scenario i will bet.
And who knows, the scanner feature could be turned into a real one as a bonus: simply attach a camera to detect cats, bugs, whatever.
I wish i made the reader wonder for a minute!
Good day, have fun!!

Older thread but it's interesting. My though is it would be far easier to partially collimate light for better penetration rather than attempt to re-scatter already collimated light. I envision a concave dome of Chip on Board (COB) leds that would have to be about 3x the diameter of the grow space being used then through collimating optics reduce the spectral foot print 3x to enhance the penetration of the light as well as being able to keep the light source further from the plant tops. Just a thought, happy growing all!

I'd like to add my 3 cents and resurrect this thread.
I think laser light grows would out perform LED grows when done right while using less power. All it takes is the right manufacturer to create the right product (or done at home DIY).
LED grow lights have red, blue and some IR lights. Well, lasers have the same spectrum available. IR is used CDs, and RED is used in DVDs, and UV is used in Blu-rays (and there's also just blue not used in anything). You can EASILY contain a laser in an adjustable collimator. You can focus for a pinpoint burning dot or turn it for a wide spread beam.
So why can't a laser grow light be created!?!? You could split one laser diode light into 5 to 10 outputs if needed for budget concerns. IR, Red and Blue lasers have been available for many years now. The computer industry has slowly progressed into using lasers from LEDs. Why can't the grow industry progress from analog light to LED light to laser light!?
Think of it, a grow light that could project the same power at 10" or 10'.
All adjustable with the twist of a ring. It's got potential. This should REALLY be investigated and tested further.
