Designers Edge L14SLED 1000-Watt Twin-Head Adjustable Work Light with Telescoping Tripod Stand, Halogen

I have the halogen work lights and want to use them for photography. Can I put aluminum foil around the light to have better control at the direction of the light? Want to know if it is safe? Also can I use the photography white umbrellas to diffuse and

A: It will likely work but I sure wouldn't use them. They throw off so much heat it may be dangerous with foil around them and the umbrellas will burn if overheated.

Light-emitting nanocrystal diodes go ultraviolet

LEDs based on solution-processed inorganic nanocrystals have promise for use in environmental and biomedical diagnostics, because they are cheap to produce, robust, and chemically stable. But development has been hampered by the difficulty of achieving ultraviolet emission. In their paper, Los Alamos National Laboratory's Sergio Brovelli in collaboration with the research team lead by Alberto Paleari at the University of Milano-Bicocca in Italy describe a fabrication process that overcomes this problem and opens the way for integration in a variety of applications.

The world needs light-emitting devices that can be applied in biomedical diagnostics and medicine, Brovelli said, either as active lab-on-chip diagnostic platforms or as light sources that can be implanted into the body to trigger some photochemical reactions. Such devices could, for example, selectively activate light-sensitive drugs for better medical treatment or probe for the presence of fluorescent markers in medical diagnostics. These materials would need to be fabricated cheaply, on a large scale, and integrated into existing technology.
