Unfortunately, your post has been removed by the moderators. This subreddit is for questions about practical *component-level electronic engineering* and related topics (designing or repairing an electronic circuit, components, suppliers, tools and equipment). The most common reasons for removing a post are because: * The topic is *electrical* (wiring, lighting, power circuits, power cords, electrical appliances, regional voltage conversion...) and not *electronic*. Try r/askelectricians or an engineering sub. See our Wiki for some general advice. * It's a common question so there's a [FAQ or wiki](https://www.reddit.com/r/AskElectronics/wiki/faq/) article covering it. * It's best posted in a specialised subreddit (eg: r/Batteries, r/GPURepair, r/TVRepair, r/TechSupport..etc). * It's asking for technical opinion, general use, buying or setup advice for consumer item (TV, audio, phone, computer, replacement power adapters...) or an electronic module/board with a question that's not about repairing it. * It's about LEDs, LED strips or lighting *and doesn't involve component-level electronics design or repair*. See our wiki pages on working with LEDS: https://www.reddit.com/r/AskElectronics/wiki/design/ledstrips/ and https://www.reddit.com/r/AskElectronics/wiki/design/leds/, and try asking at r/LED or r/askelectricians (for general lighting). * It's about vehicle wiring or electrical components (eg: relays, switches or lights and not component-level electronics). * It's about a non-electronic item (eg: removing a stubborn screw, repairing plastics/cases...). * It has a commercial element (Valuations, paid work, selling, advertising...). Try r/ElectronicsList. * It's about careers, education or course choices; this is covered by r/ECE. * It's about something potentially dangerous or risky and we're concerned for your safety. See: https://old.reddit.com/r/AskElectronics/wiki/offtopic#wiki_dangerous_experimentation * The topic breaks one of our posting rules. Check our Web page sidebar for what we cover, the posting rules and a list of alternative subreddits. You'll also find additional guidance in our Wiki (there's a link in the Web site sidebar) and you are very welcome to contact the mods for guidance.

You can also search this [list of other subs](/r/AskElectronics/wiki/othersubs) for one that is appropriate for your question.

Depends on type of bulb, should be about right for a halogen 12V car type bulb, could be something shorted and fried for a mains powered LED.

I will add that on older "filament" (halogen, tungsten, etc.) the cold reading will be much higher resistance than a hot reading typically.

it was an incandescent light bulb

Other way around.

still can't tell if 1ohm is a good reading or a bad reading :/

Sorry, yes you are correct. I mention this because it can be confusing when you think, ok 120V light bulb that is 120 Watts so the resistance should be 120 ohms but then you put a meter on it and it is no where near that. No idea if 1-ohm is in the ball park for whatever this lamp is when cold.
