A concave reflector can form a more uniform beam of light. The light source can be an LED with a nominally lambertian radiation pattern. LED can be high power requiring heatsink. Light reflected by reflector and light exiting without hitting reflector can form coinciding beams of essentially same size. Matching of sizes of reflected and unreflected components can be achieved in part by having a tangent at a rim parallel to axis of reflector. For some LEDs hot spot in center of beam is reduced by curvature becoming increasingly sharp when approaching along reflective curve a critical radius at which tangent to reflector curve in plane containing axis of reflector has angle near 45 degrees with respect to axis of reflector. Reflector can be used in, for example, work lights, desk lamps, accent lights, headlamps, and flashlights. Lamps can have multiple reflectors with one LED for each reflector.

The use of sealants based on organosilanes for refrigeration and air conditioning systems is made possible by control of the rate of introduction and viscosity of the sealant mixture within certain ranges. An appropriate choice of organosilane sealant is made to allow effective sealing of small pinhole size leaks in the air conditioning or refrigeration system. The organosilver is then combined with a miscible lubricant at particular ratios to provide the proper mixture viscosity for injection into the refrigerant system to prevent bearing seizure. specific orifice sizes are selected for an apparatus to ensure that the composition is injected at the flow rates required to prevent liquid slugging and subsequent compressor shutdown or failure. In addition, effective introduction of the mixture requires certain procedures be performed. Injection procedures are also described that prevent temporary or catastrophic equipment shutdown.
