   Candela’s hydrofoiling electric boats attract $24M investment in a bid for cleaner seas. At a stroke it makes every other boat feel strangely low-tech, as if Candela has finally managed to reinvent the wheel or, perhaps more aptly, discover flight. Candela’s C-8 flying electric boat is already selling better than gas-powered boats.

   What is a Candela in physics?

   • The 26th CGPM approved the modern definition of the candela in 2018 as part of the 2019 redefinition of SI base units, which redefined the SI base units in terms of fundamental physical constants. The lumen second is sometimes called the talbot . Luminous flux per unit solid angle per unit projected source area.

   What is a Candela in photometry?

   • The candela is the SI’s base unit for photometry—the science of measuring light as perceived by the human visual system. It is as notable for what it does not do as for what it does: It does not represent the entire amount of light shining from an object; we have a different unit called the lumen for that.

   Oct 13, 2014 · Candela: a Unit Used to Measure Luminous Intensity. We'll start with candela (cd) – also commonly called candlepower. Candela is the base measurement for describing luminous intensity. It describes how bright the light source is, which shows how far away from an object you can be while still being able to see it.
