- Well, it looks like we've run out of names for all these subtle variations!
- The ballast/transformer used with these bulbs is indeed 'electronic',
- but it is not 'solid-state' as it works without semiconductors. When it
- came in to exsistence there were no solid state parts (1940's), and
- what we call 'electronic' appliances today was limited to vacuum tube
- radio and gramaphones back then.
-
- It would be very confusing if a ballast company had put 'solid-state' on
- a tar and iron inductor, even if it is literally true!
-
- Drawing a parallel from other things in our modern world, I think all
- lighting controls will be 'solid-state' 'electronic' in the near future.
- Before that happens it looks like there is a cost driven non semiconductor
- lighting system that we are seeing in the less-than-$10-shoplights market.
-
- It wasn't a stupid question.
