Hi again,

The LEDs were made to my friend's specs. He is trying to start up a grow LED business. I inquired about the exact frequencies however he understandably explained to me that he couldn't share those specifics.

What I do know after our conversation is:

a proprietary blend of light
1 watt diodes
90 degree viewing angles
american made LEDs

The reason the flowering lights are only duo-band is because they are intended to be used with UVB cfls.

The veg lights use 4 bands of light because they need more of that spectrum in the veg state.

:thumbsup:
