60 and 90 degree beam angle

Iv'e tried to find info on this, but can't seem to come up with much. I would like to the difference in penetration. I know 120 degree is too wide. Some companys use all 90 and others use a combination of 90 and 60. How tall should your plant get before 90 degree stops getting all the way through? and the 60 degree?

120 degrees can be too wide....i use 120-140 degree floodlights, so i can get super close with no bleaching. I guess my advice would be to use a combination of 60 and 90 and experiment with your plant heights and panel heights and training techniques. LED growing for your 1st time (assuming) can be a steep learning curve.

Yes, it will be my first grow with leds. I do beleive they are the future of growing. I haven't bought one yet. Still gathering info to ensure I make the right choice. What wattage are your lights and how tall do you grow your plants?

Well you have come to the right place for advice on LED's. Everyone is really helpful.

I do things a little left of center....

Anything less than 90° is going to cause trouble ...
Anything more than 120°-130° ,has a lot of light " wasted " sideways ...

90°-130° is a sweet range ,for led light " cones " ...
Light from different leds blends good enough , in short distance away,from panel(s) ...
While it remains "gentle" to leaves and photosystems and allows leds to be placed closer to plants ...
-Less wasted photons - ....


And ...

Blue light disperses fast and easy ..
And you want blue light (whether coming from blue leds or Cool Whites ) to be
as much dispersed as possible ...Otherwise trouble will occur ,most probably ....
So here wide angle of emission is wished ....

To the other side ,now...
Reds ...
Red light is kinda of "directional" light ..
It does not disperse easy ...
This can cause photoinhibition ,photorespiration and light saturation to certain areas
of leaf canopy ,where red photons will " fall " in amounts that the Photosystems either can
handle for short time or not at all ....
"Burn baby ,burn ..."

So ,also at this case ,wide angle of emission is wished,to disperse the "directional "red light ...
