I am finding these light testing videos really annoying, the first two I watched only showed testing one end of the bulb, now this one doesn’t tell me what multimeter setting to use for the ballast leads.
I have a problem with several under-counter fluorescent lights that have been burnt out for a while. I bought a pack of 5 off eBay, and only 2 out of 5 worked. They appear fine, but 3 wouldn't light. I also bought a pack of 3 from Amazon. One I replaced, and it works fine. The second fixture was burnt out as well, but neither of the extra 2 works in the remaining fixture. Why so many apparently bad bulbs? None should have come on if a bad ballast but only 2 out of 5 replacement bulbs worked. I don't understand why such a high percentage of replacement bulbs off eBay- damaged in shipping? They are t5 16 and 20-inch bulbs.
Your test at 4:40: You put the multimeter's terminals in the connector. A guy in another video puts only one in the connector and one on the ground cable...
Can you use a simple continuity tester to check and see if the bulb is good or not ? Mine 'beeps' when you touch the leads of the tester together so I'm guessing a beep when you put the pos and neg leads onto the two pins that stick out of the ends of the bulbs means the bulb is good , right ? Thanks !
@@cagmito76 I tested my bulbs T8 thin after seeing your video with my meter on olms and they read 30 ohms so I knew they were good, and they worked in another fixture. I want to check the ballast and wonder if I can check the voltage at the pins holes with my meter set to 240 volts?
Get a volt reading and a amp reading on one of the good ones and multiply those 2 numbers together for watts. Like here in U.S. a 120v system drawing .25 amps is a 30 watt. V x A = Watts
Could you add English subtitles please 🙏

You have an option for this from RUclips. Click on the sort of star on the bottom-right corner of the video. Activate the subtitles there.

Wow! This program start electronic ballast start up very nice ^^
Glad you like it!
Helpful, thanks!
Your test at 4:50. My multimeter did not beep and yet the light is working.

How do you know if the fixture or the holder is working?
With the power on can you test the pin holes on the fixture for voltage to see if the ballast is ok? And what should it read? 120 volts or what?
I cannot advise to test live equipment , sorry. The transformer / Ballast will have all voltages on it.
that one didn't have the tiny starter cylinder?
You sound like Ozzi mate 😂 🍻

Yes, it tells you the filaments are ok at least, i cover that in the video if i remember correctly.

Mine is about 6ohms each side. But i don't know the wattage of the bulb, there is no info printed on the bulb. How can i find the wattage?

Sorry dude. Cant understand you
British nose bro. No nasal air. Always congested. That's why they have bad teeth. Mouth breather.
can't you just test for voltage?
I try not to show live testing only isolated circuits. But yeah if your careful and have good equipment for testing and safety.
You should talk more clearly
