Yes, you can use a 32 watt T12 fluorescent lamp in a fixture that previously housed a 40 watt T12 fluorescent lamp. However, the light output will be slightly lower. It's advisable to check the fixture's compatibility with the lower wattage lamp to ensure proper performance.
Yes, the wattage is just the power consumption. A 30 watt Fluorescent will give more or less the same light as a incandescent bulb or 60 watts, which is the limit for your fixture for incandescent bulbs.
Fuses are not rated in wattage, they are rated in amperage and voltage.
It depends on the voltage and whether the lamps are actually 40 watts or 40 watt equivalent. Watts / volts = amps
It would depend on the wattage of the fluorescent tubes. As a rough estimate, you would need about 6-8 standard 40-watt fluorescent tubes to approximate the light output of a 1000-watt metal halide bulb.
To calculate the annual cost of running a 40-watt 4ft fluorescent tube, you need to know the cost of electricity per kilowatt-hour in your area. Usually, a 40-watt fluorescent tube is on for about 8 hours per day, so you would multiply the wattage (40) by the hours/day (8) to get watt-hours per day. Convert that to kilowatt-hours and then multiply by the number of days the light is on per year. Finally, multiply that by the cost per kilowatt-hour to get the annual cost.
voltage, current and power factor
Yes, you can use a 36-watt electronic starter with a 40-watt fluorescent tube, as electronic starters are designed to work with a range of wattages. However, the performance may vary, and the tube might not operate optimally. It's always best to check the manufacturer's specifications to ensure compatibility and avoid potential issues.
Yes you can.
The main types are: Incandescent 10 lumens per watt Halogen 13 lumens per watt Fluorescent 40-50 lumens per watt LED 40-60 lumens per watt Lumens measures the brightness, watts measures the electric power used.
To achieve 1000 lux, you would need approximately 6-7 40-watt fluorescent lights per square meter. Lux is a measure of illuminance, so the number of lights required can vary depending on factors such as the height of the lights and the reflectivity of the surfaces in the room.
It is not a waste of money if you need the light but that being said, the higher the wattage usually reflects in a higher cost to the consumer. To answer this question the voltage and current of each device should be stated so that calculations could be made. An energy saving fluorescent is driven by an internal ballast and it is the ballast input current that is needed.
