Abstract: The present invention relates to a low profile, handheld inspection lamp with a unique configuration. Light of different wavelengths is emitted along different portions of the length, and an opaque slider allows the user to select the preferred wavelength of light for a particular task.

Abstract: The present invention relates to a low profile, handheld inspection lamp with a unique housing configuration. The slim thickness and increased width provides an innovative design that creates a “shadow box” effect to reduce the amount of surrounding room light that illuminates the area being inspected, thus increasing the fluorescent response.

Abstract: A container including a mixture of refrigerant and leak detection dye medium is disclosed for adding to an air conditioning or refrigeration system. The container includes a storage container adapted to communicate with an air conditioning or refrigeration system for supplying material inside the container to the air conditioning or refrigeration system. A refrigerant is contained within the container, along with a leak detection dye medium. The dye medium including a dye adapted to fluoresce when exposed to incident radiation below about 500 nm. The dye medium having an initial state where at least a portion of the dye medium is in a non-liquid form separate from the refrigerant and includes a concentrated dye, and a second state where the dye is dispersed or mixed with the refrigerant. A method of forming the mixture within the container is also disclosed.

Abstract: In an embodiment of a method of detecting leaks in a brake system, a dyed brake fluid is introduced into the brake system; and portions of the brake system are illuminated with a light having a wavelength below about 500 nm, the light designed to cause the dye within the brake fluid to fluoresce when illuminated, thus indicating the leak.
