Still, even with our limited vocabulary, new words are created everyday. For example, when new products are created, there is often a need to create new words. In fact, did you know that there is a new word born every 98 minutes? Depending on your criteria of what a word is, that number could be more than a million. Luckily no one person needs to memorize all of that! There are known differences between the vocabulary level of a teenager and an adult. An average teenager knows approximately 3,000 words.
This instantaneous production of light is achieved by the use of electronic ballasts. Electronic Ballast is a device which controls the starting voltage and the operating currents of lighting devices built on the principle of electrical gas discharge.
Electronic ballast use 25% less energy than magnetics, do not hum or flicker when starting, and have a lower THD. Do Fluorescent Lights Flicker with Electronic Ballast? Because electronic ballast operate at higher frequencies than magnetic ballast, the amount of light flicker is minimized. This reduces eye fatigue in some people.
