So long efficiency ...
One of my main concerns ,always there regarding individual monochromatic leds ,comes
from my 'belief' (more of a religion ,after all ? ) into '
full spectrum '...

.... white light ...
( 'Full spectrum ' ....Anyway ..It's a commonly used '
compromise ' term ,I guess .
To express/mean 'easily' the PAR/visible 400-700 nm E/M radiation wl range ...)
I've started in my first 'led world baby steps ' from/with monochromatics ...
Soon to realise their pros ..
Of their high efficiency ...
Of 'targeted' wls (desired in many of cases ) ...
And their cons ...
Very difficult to 'blend' the light ...( aka 'disco effect ' )
Plenty of electrical design difficulties due to different Vf / If ....
'Un -even efficiencies/ intensities ' made things ,even worse ...
( many reds vs few blues ...for example...
Blue are way powerful ...Underneath them, is way 'too much' ...
Away from them ,blue light disperses a lot ....
Way difficult to make light 'blend ' ...
Red light dominating parts at canopy here , blue light dominating spots there ... )
Plus ,the fact that in order to create 'a full ' white light from monochromatics ,they can
not just be used the red-green-blue ones ...The more wls the ..."
better " ....
Regarding the quality of light ....only ...
Because the design and efficiency go to hell ...

.....
Green / yellow / violet leds are way unefficient ...
If you add cyan ,amber ,FR ,UV ,etc ...
I just want to see how you're going to install /place all these and have a nice ,blended light ...
![Confused :-? :-?](/styles/smilies/icon_confused.gif)
There's no -efficient -way ....
You can 've a blended light ,like those two aquarists ,but then ..efficiency suffers ,quite a lot ...
So ,what';s left ....?
Aaa!!!!!
Phosphor conversion whites ! (And quantum -dot ones ....Nowdays ! )
Ok ..
They are not (used to ...
![Fire Devil :fire: :fire:](/styles/smilies/FIREdevil.gif)
...) so efficient like the monos ....
But ....
They have so muxh 'pros' to balance or even 'make up for' the efficiency losses due to
phosphor conversion losses & absorption ...
Way many 'pros' ,nowdays ...
Specially the COB tech ,gave a serious "kick" ,
a 'boost' in those desired characteristics of pc /qd
white leds ....
To some (like me ) they 've become 'one-way' ....
The only way ...
(At least for the moment being .....
....Until further notice ...LOL
)
Cheers .
