A lamp using a gooseneck. A gooseneck is a semi-rigid, flexible joining element made from a coiled metal hose. Similar to its natural counterpart, it can be bent in almost any direction and remain in that position. [1] Areas of application for goosenecks are movable brackets for lights, magnifying glasses, microphones and other devices. [2]
Single weight chain lamp. This construction uses a chain to keep the arm with the counterweight and the forearm parallel. The lamp-cap and counterweight move in opposite directions (both away from the base or both towards it). The balance that is required is shown by the following formula: d 1 = Lamp-cap to base; m 1 = weight of lamp-cap

Left to right: MR16 with GU10 base, MR16 with GU5.3 base, MR11 with GU4 or GZ4 base Line drawing of an LED MR16 lamp, with a heatsink rather than a reflector. A multifaceted reflector (often abbreviated MR) light bulb is a reflector housing format for halogen as well as some LED and fluorescent lamps.
Behind each lamp was a back-coated spherical glass mirror, which reflected rear radiation back through the lamp and into the lens. Further samples were installed at Howth Baily, North Foreland, and at least four other locations by 1804. But much of the light was wasted by absorption in the glass. [6] [7]
In epifluorescence microscopy, the objective lens acts not only as a magnifier for the light emitted by the fluorescing object, but also as a condenser for the incident light. The Arlow-Abbe condenser is a modified Abbe condenser that replaces the iris diaphragm, filter holder, lamp and lamp optics with a small OLED or LCD digital display unit.
Harry designed lamp bases and shades for the Duffner & Kimberly Company. (A note: Oliver's half-brother, Arthur Stone Kimberly (1857-1933), was a director of the Duffner & Kimberly Company, and most likely was an investor, as well.) Oliver Kimberly worked for Tiffany in the window department, but was transferred to the lamp department.
