What is a ballast factor and how does it affect fluorescent …
The ballast factor for an electronic T8 ballast typically comes in three varieties – low, normal, or high. In addition to the effect on light output, there is also an indirect impact on energy consumption. In general, the lower the ballast factor, the less wattage your system will draw. See more A ballast factor is a number, typically between 0.70 and 1.2, that tells you how much light a lamp will emit with that ballast. So how do … See more One of the most important choices when picking out a ballast for a fluorescent system is the ballast factor. Here are our guidelines on choosing ballast factor. See more Linear fluorescent products are incredibly common in commercial spaces, so hopefully this will help you cut through the jargon and know what … See more When you’re trying to get the most savings and efficiencyout of a linear fluorescent system, the first place you typically look is the lamp wattage. You might think that a 32W fluorescent T8 consumes 32W and a 25W high-efficiency … See more WebThis paper presents the detailed implementation of an electronic ballast, for a fluorescent lamp. The circuit is commutated smoothing circuit, power switch, and driving circuit. It is a low-voltage starter, non-stroboscopic, has no noise, energy efficient, and has high power factor with very high switching speed. china sentence death
