Do Fluorescent Bulbs Flicker and Buzz?
The first generation of fluorescent light bulbs used magnetic ballasts rather than electronic. What this basically meant was that it took longer for the charge to get to the bulb causing it to flicker, make noise and take a bit to warm up. The connection was not as strong or consistent. Similarly, they also used mono-phosphors rather than multiple-phosphors, causing the light emitted to be a bland yellowish tint. Since then, the technology has made leaps and bounds. While once they were the very definition of institutional gloom, they now come in even more variations of white (and color) than the older generation bulbs. The only difference left is the cost.
