In the inner workings, I think "analog" ballasts use large wire wound transformers, and "digital" ballasts use transistors.

Analog ballasts often have a characteristic "hum" to them that you might notice somewhere with old florescent lights, or the mercury vapor "security" lights.

Digital ballasts use transistors which should push more lumens out of your bulb than a comparable analog ballast would. So it makes better use of your bulb.

Transformers are made of a bunch of wire wrappings which means an analog ballast usually weighs much more than its digital counterpart.

thanks for the reply!

i think it means you can plug you freeview box into it with it being digital LOL
