Does the energy-saving lamp have a filament

Let me help you solve it. The so-called energy-saving lamps that make filaments in my family are fluorescent lamps (fluorescent lamps) or spiral lamps, and so on. Now, except for LED and hernia lamp, almost all lamp bulbs have filaments, which he can see and touch. You can try to pry them open and see that most of them are spiral. It says you can study hard if you don't understand. Don't talk nonsense There is also the landlord, not a straight filament, but two corners at both ends, each with a filament.
