[luminous light] Tarantula Nebula (Post on: 2011-11-17)
The Tarantula Nebula has an apparent magnitude of 8. Considering its distance of about 160,000 light years, this is an extremely luminous non-stellar object. Its luminosity is so great that if it were as close to Earth as the Orion Nebula, the Tarantula Nebula would cast shadows. In fact, it is the most active starburst region known in the Local Group of galaxies. It is also the largest such ...
[luminous light] Nebulas cool, dusty clouds exposed (Post on: 2011-11-17)
A stunning new image of the Carina nebula reveals cold, dusty cosmic clouds where violent and dynamic star formation is taking place.
[luminous led] APEX Provides New View Of Carina Nebula Star Formation (Post on: 2011-11-17)
[ Watch the Video ] Observations made with the APEX telescope in submillimeter-wavelength light reveal the cold dusty clouds from which stars form in the Carina Nebula. This site of violent star formation, which plays host to some of the highest-mass stars in our galaxy, is an ideal arena in which to study the interactions between these young stars and their parent molecular clouds. Using the ...
[luminous led] China LED street lamps stay bright despite dull start (Post on: 2011-11-17)
The global trend of greening and emission reduction has placed LED as a top option in terms of lighting technology. Unlike HID and mercury lamps, LEDs tout longer lifespan, energy efficiency and respectable luminous efficacy (a total luminous efficacy of >100-130Lm/W and an application luminous efficacy of >50Lm/W).

[luminous flux] NEMA Publishes ANSI ANSLG C78.21 Incandescent Lamps and ANSI ANSLG C78.40 Electric Lamps (Post on: 2011-11-17)
Providing physical and electrical characteristics of incandescent lamps, ANSI/ANSLG C78.21-2011 describes PAR and R bulb shapes. Standard covers lamps with clear, frosted, and lens end bulbs; clear and prescription lenses; and various reflector coatings. ANSI ANSLG C78.40-2011 Electric Lamps: Specifications for Mercury Lamps sets forth physical and electrical requirements for single-ended metal ...
