Great simple and to the point, thanks. However you didn't mention to check both ends of the straight tube (although that would be obvious to most people). Nice to see what's inside the tube and to understand what's going on.
Thanks!! Super helpful info. Way easier to test the tubes rather than the ballast to identify which is the culprit before going to the hardware store buying unnecessary parts. And, there was no unnecessary info -- great video.
Excellent. My 4-prong blacklight bulb for my bug zapper went out after only a month. Now, after I check it, I can see if it's the bulb, or the zapper. If it's the bulb, maybe Home Depot will just replace the whole thing. Thanks!!!
What if you read 2.5 at one end of the tube and nothing on the other end. Can one end be good and the other end not. Or does one end not read this measurement. I doubt it but have to ask.
@Boogie Man hfs ballast is a high frequency ballast which gives a dc output most of the time. I have one running on a 7.4 volt battery and it also runs tubelights with only one intact cathodes. The tube is an 8 watt T5
Seen a guy driving a big 4×4 with those round flourescent lights on the backside of his wheels they were bright! Sure did look weird coming down the road!
Hi, I have several T4 400mm cabinet lights, 3 of these failed within a day of each other, I tried changing bulbs around with the lights that are working,also tried plugging the duds into where good lights are, these units cannot be opened,so is there some way I can test them with a multi meter, thanks.
@FixitSam thank you indeed for this informative video.. Would you please make a video how to test ballast of a fluorescent tube using a multimeter? Thank you ❤
@@FixitSam well, I've never seen 8 ft long round filament-style bulbs. And my contractor says they are fluorescent. They were purchased around 2009 I think.
I've had the same single post fluorescent tubes since I moved into this house over 3 decades ago. I suspect they're somewhat like regular light bulbs, in that there's two terminals on the one end. I'll be testing some myself today to see if that's the case. @@FixitSam
Where can you buy T12 tubes nowadays? Why is T8 tube better, I am confused as some say that it has electronics inside Can you use T8 tube with old starter and ballast setup? (I dont want to change those as I dont like the instant electronic crap starters (they cause interference to my sw radio) that they want you to buy nowadays
@@OggyGTA not if you re far from home. I sometimes carry 9v battery when i m about to pick some tubes. Just to test them on the place to leave the bad ones behind.
It doesn t always meen that the black end of a tube is dead. Try to test a tubelight with a 9v battery. Sometimes the black end still glows orange. When this happens, tube is still functional
Exactly the right amount of information delivered simply. Increasingly rare to find that on YT these days. Thanks
My impression too. All the information required without any unnecessary waffle.
Exactly.. Would love to see more of this
Excellent , no fuss , no long story , straight to the target ...we need infos not your life ! (for other youtubes related to fluo testing)
20 years working with these and I didn't know this. Thank you

This is a great video!!! Its easy to understand and explains why and what of what needs doing. Why can't all videos be like this one? 😅
Excellent thanks. 19 people gave this thumbs down - what, was it too difficult for you!!
19 meat heads
Thanks , very helpful, always wondered if it was the tubes or the ballast.
Perfect explanation, short and to the point like most commenters say!
Actually the correct video in the TH-cam. Thanks in advance ❤
I have single pin terminations on 8 ft. fluorescent tubes. How does one go about testing that type of bulb? Thank you!

This video was STRAIGHT 2 the point THANK U
Well done. Right to the point.
How do you test a t12 bulb with only a single post on each end?
simple and to the point, thanks.
What if you read 2.5 at one end of the tube and nothing on the other end. Can one end be good and the other end not. Or does one end not read this measurement. I doubt it but have to ask.
There's filaments on both ends. He just tested one end on the video, but you should test both.
@Boogie Man sometimes a tube with one intact filament still runs on hfs ballast
@Boogie Man hfs ballast is a high frequency ballast which gives a dc output most of the time. I have one running on a 7.4 volt battery and it also runs tubelights with only one intact cathodes. The tube is an 8 watt T5
Simple and to the point!
Straight to the point, much thanks, and thumps up from me
I have power coming all the way out to the socket with the four plug hole but all bulbs Iplug in don't light up . What do I do?
Great video. Do you have anything on testing electronic ballasts please?
Can you test the starter in the same manner?
Thanks, exactly what I was looking for. Is it the same for Led tube?
It don't get any better than that. Subscribing to this asap. Where were you when I was studying nuclear physics?
Great video easy to follow.
Super helpful. Thanks dude.

Thanks, I needed that.
Bob’s your uncle. Thank you sir 🙏🏾
@FixitSam thank you indeed for this informative video.. Would you please make a video how to test ballast of a fluorescent tube using a multimeter? Thank you ❤
Perfect! Thanks!
I only have 1 rounded terminal on each end. How do you test that?
Are you sure its a fluorescent bulb? (As opposed to a filament/incandescent)?
@@FixitSam well, I've never seen 8 ft long round filament-style bulbs. And my contractor says they are fluorescent. They were purchased around 2009 I think.
Same issue for me. And it's definitely a fluorescent bulb. One terminal at either end.

ok seems simple enough thanks dude
Excellent vid.
A conducting filament does not mean that the tube is ok. The most common failure of fluorescent tubes is that the filament coating is depleted.
Result! Thank you sir
Thank YOU! learned something today :)
Thank you.

Awesome job thank you
I could have told you that without the multimeter! lol. I know, this can be helpful for other tubes...
just touch both the filament ends with a 9 volt battery. if it doesn t light orange the filament is blown.
@@averageslytherinperson6154 Easier with a multimeter to be fair!
@@OggyGTA not if you re far from home. I sometimes carry 9v battery when i m about to pick some tubes. Just to test them on the place to leave the bad ones behind.
@SIMPLE SPIN try changing the glow starter
Thank you
thanks, very good video
0.5 means 5 ohms?
It means half or .5 of an ohm.
Thank you!!!!

Simple and informative instructions. Thanks for sharing.
Brilliant, thank you.
Damn, I don't have tester,
I was hoping I could shake like regular lightbulbs!!!
Great info
Excellent thank you!
How to test a fluorescent bulb with out a multi meter
it should have taken only 30 seconds to explain and not 2.26 minutes
Gee, and here I thought he was pretty succinct myself!
