The anniversary is a good time to take a closer look at the results and lessons learned, with more than 80% of the LED fixtures planned for phase one deployed.
The packaging and testing phase account for close to 60 percent of the cost of an LED today so unified semiconductors would further help drive down unit costs, while increasing throughput.
The second phase of the mission, for which a date has to be confirmed, will be led by overall team leader Christopher Young, an expert on conservation of historic environments.
