To determine if a fluorescent bulb or ballast is bad, you can start by checking if the bulb is flickering, dim, or not turning on. If the bulb looks blackened or has dark spots, it may be faulty. You can also test the ballast with a multimeter to see if it is providing the correct voltage. If these steps don't solve the issue, it's best to consult a professional for further assistance.
You can tell if a fluorescent bulb is bad by checking for flickering, dimness, or a delay in turning on. If the bulb is making buzzing or humming noises, or if the light is inconsistent, it may also be a sign that the bulb needs to be replaced.
To test a fluorescent bulb, simply turn it on and observe if it lights up evenly without flickering or dim areas. If the bulb does not light up or has flickering/dimming issues, it may need to be replaced.
To measure a fluorescent bulb accurately, use a tape measure to determine the length of the bulb from end to end. Make sure to measure the bulb while it is turned off and cool to the touch for safety. Record the measurement in inches or centimeters for reference when purchasing a replacement bulb.
To accurately measure the brightness of a fluorescent bulb, you can use a light meter or a lux meter. These devices measure the amount of light emitted by the bulb in units called lux. Place the meter close to the bulb and take a reading to determine its brightness.
As long as the tube is intact there is no difference between whether it is burnt out or not. You shouldn't smell anything from inside the tube. Fluorescent bulbs to have a ballast which may emit a smell if it is faulty. In this case you may have a bad ballast and not a bad bulb.

F17 on a fluorescent bulb packaging typically indicates the type of bulb and its wattage. In this case, "F17" refers to a T8 fluorescent bulb that operates at 17 watts.
EEdmund Germer (90% sure) made the first fluorescent light bulb
A fluorescent bulb
The fluorescent light bulb more efficiently converts electricity to light resulting in less heat produced. But in winter, heat being produced is not exactly a bad thing. Besides, fluorescent light bulbs are more expensive and have heavy metals in them, making them more toxic.
fluorescent light bulbs are usually from 9$-15$.
No, a fluorescent bulb does not emit the same amount of heat as a metal halide bulb of the same wattage.
