Advanced led has put up pre-orders for their new cree 450-460nm xte panels with 660nm osram chips..........no white in 2014?? I guessed wrong on them jumping on the R/W spectra "bandwagon".........interesting call for sure.
what the hell happened to the ARC series btw?????..........idk, weird
One could be thinking ,that with the latest improvements in phosphor conversion led light generating and with the COBS hitting the market ,that monochromatic leds would be rendered as useless in LED horticulture ....
Actually ,the opposite is happening.
The increase in efficiency terms of the pc white leds ,just came to underline the importance of monos ...
In the old days ,it was out of question to grow with just red & blue leds in high irradiances ...
Other wls were missing ,plant would get saturated ,inhibited ,or even fried ...
And while today's white leds cover very well the need of "multi- wavelength photosynthesis'" at high irradiances,
we should not forget that they are made for human vision purposes and not for horticulture ...
So,along with utilising efficient whites ,the next generations of led grow lights* should and hopefully will incorporate
selected monochromatic leds ....
Mainly for two reasons :
1 ) 'Fill" the wls ' missing " from pc whites ...(For example : Cyan & Deep reds )
2) Alter the quality of light ,depending on growth stage/ species/ cultivar /etc ,
in such way that certain photomorphogenic attributes will be diminished or enhanced ,
thus affecting certain metabolic pathways ,regarding the growth,reproduction
and ...production of plants.
(With UV,blue ,red,deep red and Far red monochromatic leds ,being the most crucial )
*(And all that for led lights that they
do not utilise
proprietary pc leds { Valoya } or
proprietary multichip leds
{ Illumitex } ....)
Monos are back.To 'blend' with 'whities'.
In order to introduce versatile and highly efficient horticultural Solid State lights.
It never ends,indeed.
Cheers.
