Compact IR LED Light Emitter enhances night vision camera range.

2013-02-08 14:31:12| Industrial Newsroom - All News for Today

Producing light in 850 or 940 nm range, 2  x 2 in. LEDLB-1-IR improves range and resolution of night vision cameras and devices reliant on IR light. IR beam reaches up to 225 ft long in spot configuration and 45 ft long x 40 ft wide in flood. IP68 waterproof to 3 m of submersion, housing is constructed of extruded aluminum with unbreakable polycarbonate lens. Emitter operates from 9–42 Vdc supply, making it suited for connection to 12 or 24 V power sources, and has 3 W, ¼ A draw. This story is related to the following:Infrared Emitters | LED Lighting

Fracking seen by EPA as No. 2 emitter of greenhouse gases

2013-02-06 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Bloomberg: Natural gas and oil production is the second-biggest source of U.S. greenhouse gases, the government said, emboldening environmentalists who say tighter measures are needed to curb the emissions from hydraulic fracturing. In its second-annual accounting of emissions that cause global warming from stationary sources, the U.S. Environmental Protection Agency for the first time included oil and natural- gas production. Emissions from drilling, including fracking, and leaks from transmission pipes...
