2. Phase-out of incandescent light bulbs - Wikipedia

   en.wikipedia.org/wiki/Phase-out_of_incandescent...

   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.

3. Luminous efficacy - Wikipedia

   en.wikipedia.org/wiki/Luminous_efficacy

   Luminous efficacy can be normalized by the maximum possible luminous efficacy to a dimensionless quantity called luminous efficiency.The distinction between efficacy and efficiency is not always carefully maintained in published sources, so it is not uncommon to see "efficiencies" expressed in lumens per watt, or "efficacies" expressed as a percentage.

   For example, a 100-watt, 1000 hour, 120-volt lamp will produce about 17.1 lumens per watt. A similar lamp designed for 230 V would produce only around 12.8 lumens per watt, and one designed for 30 volts (train lighting) would produce as much as 19.8 lumens per watt. [ 77 ]

5. LED lamp - Wikipedia

   en.wikipedia.org/wiki/LED_lamp

   Color rendering quality is specified by the color rendering index (CRI), and as of 2019 is about 80 for many LED bulbs, and over 95 for more expensive high-CRI LED lighting (100 is the ideal value). [citation needed] RGB or trichromatic white LEDs use multiple LED chips emitting red, green, and blue wavelengths. These three colors combine to ...

6. Centennial Light - Wikipedia

   en.wikipedia.org/wiki/Centennial_Light

   The Centennial Light was originally a 60-watt bulb, but has since dimmed significantly and is now as bright as a 4-watt bulb. [7] [8] [9] The hand-blown, carbon-filament common light bulb was invented by Adolphe Chaillet, a French engineer who filed a patent for this socket technology. [10]

7. Easy-Bake Oven - Wikipedia

   en.wikipedia.org/wiki/Easy-Bake_Oven

   The original Kenner Easy-Bake Oven was heated by two 100-watt incandescent light bulbs, one above the food tray and one below. The idea was that the cake would bake more quickly and evenly if heated from both sides. Later models used only one bulb, leveraging convection from better interior heating dynamics to achieve the same results. [13]
