[citation needed], More contemporary "Edison light bulbs" are designed to replicate the same light color and bulb shape of the original, but offer a more energy-efficient version to Rosenzweig's popular vintage reproduction bulbs (modern tungsten coils are already more efficient). [13], A 2010 article in The New York Times noted that some restaurants were hanging hundreds of Edison light bulbs from their ceilings, stating: "Whether in hip hangouts tapping into the popular Victorian industrial look or elegant rooms seeking to warm up their atmosphere, the bulb has become a staple for restaurant designers, in part because it emulates candlelight and flatters both dinner and diner. Physicists recognize two points in the gradual increase of neutron flux which are significant: critical, where the chain reaction becomes self-sustaining thanks to the contributions of both kinds of neutron generation,[13] and prompt critical, where the immediate "prompt" neutrons alone will sustain the reaction without need for the decay neutrons. Find and evaluate OEMs, Custom Manufacturers, Service Companies and Distributors. Most of the bulbs in circulation are reproductions of the wound filament bulbs made popular by Edison Electric Light Company at the turn of the 20th century.
