Digital ballast are much more efficient and more reliable than the traditional transformer ballasts. Digital ballasts are more efficient at producing light than a transformer ballasts. The digitals also run much cooler than Transformers and are much more silent. Though some user may enjoy the transformers more, digital ballasts are more popular and are sold more often online.
Yes, a ballast transformers has two special secondary windings to provide the proper low current. Also, Ballasts can operate more than one type of lamp.
A pulse start lamp can work with a metal halide ballast, but compatibility depends on the specific ballast and lamp type. It's essential to ensure that the ballast is rated for pulse start lamps, as not all metal halide ballasts are designed for this purpose. If the ballast is compatible, the pulse start lamp can provide improved efficiency and better performance compared to standard metal halide lamps. Always consult the manufacturer's specifications for optimal results.
depending on voltage supplying the bulb, each ballast spicifies on it such rating. many ballasts have better efficiency at higher voltage. however; say 175 watt bulb, 120V with 80% efficiency= (175/120)/.8=1.82amps
If it's a fluorescent light, the sound is probably caused by a faulty ballast. <><><> If the light is incandescent and connected to an inexpensive dimmer, noise from the dimmer can cause the filaments to "sing." Better dimmers have better noise filtering.
It depends on the type of downlights being used. LED downlights generally do not require a transformer as they operate on low voltage directly from the mains. However, if you're using traditional halogen downlights, they typically require a transformer to step down the voltage to a safe level for the lights to operate.
If you use a non-dimmable Compact Fluorescent Lamp (CFL) in a circuit controlled by a dimmer switch no damage will be done but the CFL will stay bright when the dimmer is turned down whilst any other normal incandescent lamps wired into the same circuit will go dim in the normal way.Dimmable Compact Fluorescent Lamps are now available, for example in the Megaman range of CFLs. For more information see the Related Link shown below.Incandescent dimming uses any incandescent lamps and an incandescent dimmer.To dim fluorescent lamps usually requires use of fluorescent dimmers AND fluorescent dimmable ballasts. If these two components do not match, dimming will not work.The fluorescent lamps themselves are the same whether you put them in a standard (nondimming) ballast or a dimmable ballast.If your dimmers are not dimming the CFLs they are either not fluorescent dimmers or, more likely, your ballast in the light fixture is not a dimmable ballast.
The main differences between a T8 and T12 ballast are their size and efficiency. T8 ballasts are smaller and more energy-efficient than T12 ballasts. This means that T8 ballasts can provide better performance and save more energy in fluorescent lighting systems compared to T12 ballasts.

Electronic ballasts are more efficient than magnetic ballasts because they produce less heat and consume less energy. They also provide better performance in terms of light output, flicker reduction, and dimming capabilities.

It is better to determine the efficiency of a transformer indirectly through measurements and calculations because direct loading can cause overheating and damage to the transformer. Indirect methods are safer, more accurate, and do not risk the operational integrity of the transformer.
an ipod is better than a digital camera
Back to back testing of a transformer can be better explained if you check the diagram in the resource area.
A CVT (Constant Voltage Transformer) is always better than a Servo Stabilizer. But a CVT is costlier than a Servo Stabilizer of same rating.
An oil transformer is filled with PCB oil to better transfer heat from the windings to the outside case (and into the air).
what is digital technology
You put on/in a ship or raft etc. That makes it float better or makes in more stable
Optical zoom is way better than digital zoom as digital only expands the picture. Optical zoom actually zooms in.
