- ballast factor (BF) - The ratio of the light output of a fluorescent lamp or lamps operated on a ballast to the light output of the lamp(s) operated on a standard (reference) ballast. Ballast factor depends on both the ballast and the lamp type; a single ballast can have several ballast factors depending on lamp type. compact fluorescent lamp (CFL) - A family of single-ended fluorescent-discharge light sources with small-diameter [16-millimeter (5/8-inch) or less] tubes.

Changes in vessel diameter are frequent and significantly. alter peripheral resistance. The smaller the tube the greater the resistance. Resistance varies inversely with the fourth power of vessel.

- Since the power factor of the ballast doesn't change much over time, we can work backwards to determine how many watts the lamp is drawing part way through its life: W = PF x V x A = 0.5 x 121.6 x 3.06 = 186W.

What is a Lighting Ballast? A lighting ballast is necessary to operate discharge lights because they have negative resistance, meaning they are unable to regulate the amount of current that passes through them. A lighting ballast must be used to control current flow; otherwise the light could fail.

- Briefly explain the functions of electronic ballast. The high frequency electronic ballast overcomes the above drawbacks. The basic functions of electronic ballast are: 1. To ignite the lamp 2. To stabilize the gas discharge 3. To supply the power to the lamp The electronic ballasts make use of modern power semi-conductor devices for their operation.

Ignition Systems Without modifying your ignition system, you can use any standard ballast coil or we offer performance ballast coils from Bosch (red coil 0221119030) or Intermotor (gold coil DLB110). Using a non-ballasted coil would mean that you are running a 12v coil on a 9v feed, resulting in a weak spark.

Weather in Orlando in late October early November? 10 days and it rained about 5 and was overcast a lot of the time. Going back this year but earlier in the end of September which we did two years back. I guess you can never really tell with the weather but it busy too as it was Jersey week in November also and the parks seemed busier the second week.

Electronic Ballast Electronic Ballasts are not. Electronic Ballasts are not the only thing that injects harmonics, besides, the level of harmonics injected is really small in the working ranges. The ranges where large amounts are injected is often in the bands which are not used in Industry and hence is largely undocumented.

Electrical ballast An electrical ballast is a device which limits the current through an electrical load. These are most often used when a load (such as an arc discharge) has its terminal voltage decline when current through the load increases.

A Summary of Regulatory Requirements PCB-containing ballasts (non-leaking) do not meet the definition of a special waste but are considered a municipal solid waste unless the generator is a manufacturer of PCB capacitors. Leaking PCB-containing ballasts are handled in the same manner as transformers as a special waste.

- I assume that you are asking about an average, household kitchen griddle. More counter-top kitchen appliances are rated in the 1,000 to 1,250 Watt range. Since Watts Amps X V … olts, if your house power is 110V (normal in the USA,) the current or Amp draw would be in the approximate 10 Amps. The amperage is on the label of the ballast. When you connect the ballast to power you will see it along with the voltage and pf of the ballast. F40T12 twin 8 foot tubes, ballast usually draws about .75 amps.

Introduction: As with a lot of terms used for aggregates, this one has several meanings. In some parts of the country, 'all-in ballast' refers to a mixture of gravel and/or small stone (<60mm) with sand, often used to make concrete. Elsewhere, it can refer to the coarse granular stone (around 40-50mm in size) used to support railway lines or as a general 'fill' material of crushed rock, slag or gravel.

- ANSI considers the 4-foot, 32-watt T8 lamp to be a rapid-start lamp, but it is commonly operated using an instant-start circuit in which the two pins on each end of the lamp are electrically connected or shunted together.or example, the reported input power for a typical two-lamp, high-frequency electronic ballast with a normal ballast factor (0.88) is 58 watts. However, the ballast input power will increase by 3-4% for lamps with 5% higher power than expected (as measured on a low-frequency reference ballast).

What is a ballast? To put it simply, a ballast is the functional heart of a fluorescent or HID light source. Just as a heart regulates blood flow to your body, a ballast ensures that a lamp stays lit by managing the distribution of energy throughout the fixture.

Fluorescent-lamp formats Typical diameters are T12 or T38 ( 11⁄2 in or 38 mm) for residential lamps with magnetic ballasts, T8 or T26 (1 in or 25 mm) for commercial energy-saving lamps with electronic ballasts, and T5 or T16 ( 5⁄8 in or 16 mm) for very small lamps, which may even operate from a battery-powered device.
