The addition of UVb diodes as an enhancement is obviously not economically viable at today's price points. But beyond price I also would be concerned as to how these diodes would be used in an indoor garden whereby the gardener might look into the diode and do permanent damage to their vision. Especially if these diodes emit in the low UVb regions. Seems like an area where product liability lawsuits could potentially loom large.
A good HPS lamp should come in @ 1.8 uMol/watt, not counting depreciation, but how much of that is emitted in usable plant absorption spectra when it's red weighted is the subject of endless debate. I see the plant results from broad spectrum inda-gro lamps coming in at 1.5 uMole/watt and in some cases these lamps have been running for over two years producing consistent results. IMO the future advances in indoor garden lighting will be in the development of technologies and controls that bring the strengths, of what today we might consider to be competing technologies, together to benefit the end user.
good thread
