the current bulbs have to be replaced every four years

Asides from Mitsubishi Electric, three other companies helped to make the OLED Geo-Cosmos display: Dentsu Inc. undertook project planning, Go and Partners, Inc. developed the image-processing and transmission system, and GK Tech Inc. created the spheroid design.

Currently, San Francisco Water, Power and Sewer kick off a city-wide project late this year to install led high bay light to replace 18,500 high-pressure sodium street light fixtures.

In contrast to the existing street lights, the new fixtures will use 50 percent less energy and will cost far less to maintain since they only have to be replaced every 15 - 20 years while the current bulbs have to be replaced every four years.

The swapping out of the lighting fixtures is expected to take 30 minutes per street light with the whole project being completed in about 14 months.In addition, the lights will have smart controllers that let the city remotely monitor and adjust their light level and alert maintenance crews when the lights fail or are about to fail.

Through participation in Hawaii Energy’s Lighting the Future offering, participants will be able to see first-hand the energy and cost savings available through the use of LED lighting.Hawaii Energy is a ratepayer funded conservation and efficiency program administered by Science led linear high bay light International Company (SAIC), a science and engineering company, under contract with the Hawaii Public Utilities Commissions.

The system is capable of gathering data on things like temperature and room occupancy with sensors or motion detection cameras. That data can then be used to adjust lighting under the system's control. The system can also be set on a schedule via a Web-based platform. It uses servers to supply electricity to light fixtures via Ethernet cables using low-voltage DC instead of alternating current), improving efficiency.
