2. A-series light bulb - Wikipedia

   en.wikipedia.org/wiki/A-series_light_bulb

   The most commonly used A-series light bulb type is an A60 bulb [7] (or its inch-based equivalent, the A19 bulb [2] [4]), which is 60 mm (19 ⁄ 8 in or 2 + 3 ⁄ 8 in) wide at its widest point [3] and approximately 110 mm (4 + 3 ⁄ 8 in) in length. [8] Other sizes with a data sheet in IEC 60064 are A50, A55, A67, A68, A71, A75, and A80.

   For example, a 100-watt, 120-volt lamp has a resistance of 144 ohms when lit, but the cold resistance is much lower (about 9.5 ohms). [76] [b] Since incandescent lamps are resistive loads, simple phase-control TRIAC dimmers can be used to control brightness. Electrical contacts may carry a "T" rating symbol indicating that they are designed to ...

   The Canadian federal government banned the import and sale of 75- and 100-watt incandescent bulbs, effective 1 January 2014. On 1 January 2015, 40- and 60-watt bulbs were also banned, although there are exceptions for oven lights, decorative lamps (light bulbs), appliance bulbs, 3-way fixtures, chandeliers and rough service/utility bulbs.

   Incandescent bulbs and their retrofit replacements are often specified as "A19/A60 E26/E27", a common size for those kinds of light bulbs. In this example, the "A" parameters describe the bulb size and shape within the A-series light bulb while the "E" parameters describe the Edison screw base size and thread characteristics. [35]
