If the first digit on a lamp says 8, then the CRI of that lamp will be approximately 85. The last two digits indicate the color temperature of the lamp in kelvins (K). For example, if the last two digits on a lamp say 41, that lamp's color temperature will be 4100 K, which is a common tri-phosphor cool white fluorescent lamp.
An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm.
Round bulbs, often tinted red to reduce visible light, provide infrared radiant heat suitable for warming of people or animals, but the power density available is low. The development of quartz halogen linear lamps allowed much higher power density up to 200 watts/inch of lamp (8 w/mm), useful for industrial heating, drying and processing ...
As the electrodes heat, the lamp slowly, over three to five seconds, reaches full brightness. As the arc current increases and tube voltage drops, the circuit provides current limiting. Semi-resonant start circuits are mainly restricted to use in commercial installations because of the higher initial cost of circuit components.
Bunnings Cannington store, rebranded for promotion in February 2024. In early 2024, Bunnings temporarily rebranded one store in each Australian state and in New Zealand to "Hammerbarn", a fictional hardware shop in the animated television series Bluey. The series' creators were inspired by Bunnings when making the fictional shop. [38] [39] [40]

Electrical contacts may carry a "T" rating symbol indicating that they are designed to control circuits with the high inrush current characteristic of tungsten lamps. For a 100-watt, 120-volt general-service lamp, the current stabilizes in about 0.10 seconds, and the lamp reaches 90% of its full brightness after about 0.13 seconds. [135]
[Note 2] If a lamp has a "G" code, [Note 3] this will mean the lamp is a bipin shape and the number following the G will indicate the distance in millimeters between the pins, usually either 4, 6.35 or 10; if the G is followed by a letter "Y", then the lamp's pins are thicker than normal— thus, a G6.35 has pins that are 1 mm in diameter but a ...
