Adaptive optics permits the theoretical restrict of angular solution to be completed from a wide telescope, regardless of the presence of turbulence. hence an 8 meter type telescope, equivalent to one of many 4 within the Very huge Telescope operated via ESO in Chile, will in destiny be many times in a position to an angular solution of virtually zero.

Example text

A key consideration for improving lighting in an existing building is whether to retrofit or redesign the lighting system. ’ This would include lamp and ballast replacement as well direct replacement of reflectors, lenses, louvers, entire fixtures and controls. ’ This may involve different fixtures, relocating existing fixtures, or producing a design with more or fewer fixtures, and may also involve changes to the interior design, such as repainting room surfaces and replacing ceiling tiles to improve reflectance.

LED fixtures have been successfully demonstrated in this application and are growing popular. The focus on the maintenance benefit of long service life for LEDs is appearing to revive interest in induction lighting, which claims service life of up to 100,000 hours. Finally, taking advantage of cold weather ballasting and linear amalgam lamps, fluorescent fixtures from companies such as Alumen8 and Columbia Lighting are also now being marketed as a direct replacement for HID outdoor fixtures. 5 Major technologies to watch in the outdoor market CLICK TO VIEW TABLE Retrofits In an open letter to building owners dated August 22, 2008, then Secretary of Energy Samuel W.

The main trends include higher efficiency, longer service life and compatibility with lighting controls. Meet the newest member of the energy-efficient T8 family of 25 W, 28 W and 30 W lamps: the 23 W T8 lamp from Sylvania. These 4ft. lamps produce about 30% less light output than a standard T8 while producing 28% energy savings, suitable for coves, corridors and overlighted existing office spaces. Meanwhile, this lamp—and Sylvania’s other energy-saving T8 lamps are also now dimmable, another sign that fluorescent lighting is not only getting more efficient, but also friendlier with controls.
