Electronic ballast does not hum as much as a choke. Minute hum of electronic ballast is the small inductor and capacitor producing an oscillation for high voltage generation,
A jumbo bag of ballast typically contains around 1 ton or 2000 pounds of material. This is equivalent to approximately 0.9 cubic meters or 31.5 cubic feet of ballast.
The cost to replace a fluorescent ballast typically ranges from $50 to $100, including the cost of the ballast itself and labor for installation. It's recommended to hire a professional electrician to ensure the job is done safely and correctly.
The cost of a ballast tank can vary depending on the size, material, and specific requirements. Generally, smaller ballast tanks for recreational boats can range from a few hundred to a few thousand dollars, while larger industrial tanks can cost tens of thousands or more.
A fluorescent fixture with no tubes installed will still consume power, typically around 5-10 watts due to the ballast and other internal components. This power consumption is significantly lower compared to when the tubes are installed and the fixture is operating normally.
None it's a hole
The ballast is determined by how many passengers are present on each trip and the amount of lift that the balloon provides at takeoff. So if there's a lot of people onboard less ballast is needed and vice versa. In general it's less than 300lbs.

(3 x 2 x depth of the hole in feet) cubic feet
A 4x4x4 foot hole requires 64 cubic feet of concrete or .8 (8 tenths) of a yard.
A jumbo bag of ballast typically contains around 1 ton or 2000 pounds of material. This is equivalent to approximately 0.9 cubic meters or 31.5 cubic feet of ballast.
These tubes need a ballast to operate the tubes. The current and voltage will be marked on the fixtures ballast.
1 cubic yard of railroad ballast typically weighs between 2,000 to 2,700 pounds.
The cost to replace a fluorescent ballast typically ranges from $50 to $100, including the cost of the ballast itself and labor for installation. It's recommended to hire a professional electrician to ensure the job is done safely and correctly.
