Ok so I have some trouble here. I am trying to convert some single 4ft fixtures to LED tubes. I bought them at Walmart, the bulbs that is. I cut out the ballast and wired them up as I did some double tube fixtures in the past, both hot on one side and neutral on the other. As soon as I turned it on. So I wire it up the other way I have seen referenced where one side of fixture has no power at all and the other side is hot and neutral to each wire on that side of the tombstone. It again blew it instantly. Are there versions of these bulbs, how do I know how to wire them and what other way is there to wire them? Help me out here fellas
It's the two prong kind. I will go take a picture later but it just has the two probes sticking out on each end. Looks like every other florescent tube I have ever messed with. And match the prongs on the ones that came out. This light also worked with the florescent tube before I cut the ballast out so I know the components were good prior to this.
Mine are 8'ers. Not sure if they're the same or not. 1 round nub on each end. One end needs a hot, the other needs neutral. Power came in on the left. On the left end, one had black, one had white. On the right end, after clipping the ballast, I needed the opposite. As long as there's a hot on one end and a neutral on the other, it should work fine
The way I wired the two other fixtures I did, was just that way. They were double tube fixtures. But all hots were on one side and all neutrals were on the other. Not a problem. These the way I first wired it was that same way, it blew the tube out in a split second. Then I wired it the other way I have seen, one side no wore and then the other one of the words hot and one neutral and that blew it after a second. Had I not converted two fixtures (four total bulbs already I would just think I didn't do it right but at this point , I have no idea what's going on?
You may need hot and neutral on the left. And then the opposite.... neutral and hot on right. But I'm not sure of that at all. Just an idea
Are these conversion bulbs? From what I've seen you need conversion bulbs, and wire them per instructions... Cheaper and easier in many cases to just replace with a new LED shoplite...assuming that's what it is...bought some 4' ers at Menards for $20 yesterday, on sale for $15 sometimes. 5 year warranty on em
There's got to be a wiring diagram with the bulbs. The ones i did i removed the ballast, cut the wires off of 2 tombstones and put the hot and neutral on the other 2
I guess these are conventional bulbs? Bought at Walmart. It's a bad pic cause I didn't use the flash but on the bench is a pic of the fixture I used.
There wasn't, I looked. I guess you can't convert to these specific bulbs like Bren says??? I'm lost here.
I've never run across fluorescent replacement LED bulbs with no directions...not sure what to think here. Found this, not sure it helps any though... https://cdn.richcontext.com/media/2018/7/31/e10ea2e1-a60f-446c-a2eb-efc375ed823b.pdf
These may not be "replacement" bulbs. Maybe they only work with brand new fixtures? If I could see how they are put togeather. If I hadn't blown both I could hook a long vote to my multi meter and check which prongs had continuity and see if that told me anything.
Did you use with or without ballasts? It says replacement so id think you'd leave the ballasts in place
Pay attention to step 7 above, I bet you have shunted tombstones...click the link to see the difference
That's where I'm at too. I see them this cheap for a while new fixture and it's not worth my time to convert the old fixture. I've got other stuff that I need to fix that I can't just quickly ( and cheaply) replace. I'm surprised there's no instructions in the box or on it. Hopefully you can get it figured out
Cheaper to replace the whole light...unless you have fixtures that are "custom fit"...like the lights in the shop at work...all rigid conduit for the whole lighting grid...would be a real PITA to replace the whole shebang, at least with like quality of workmanship!
