I too am looking forward to updates on this. Assuming you have your lights on 14 hours a day, that comes to ~5110 hours per year. So if these things are really 100% bright for 70,000 hours, then you'd only have to replace them every 13 years or so. This assumes that you'd ditch them before they get a chance to go down to 70% efficiency. If you'd still keep them for the additional 100K hours, you'd only be replacing your lights once every 33 years!

Anyone know if Inda-Gro actually guarantees those results? On the 70K hours plan the hardware would cost about 60 bucks/year, and under the 170K hours plan, 24 bucks/year.
