Led replacement for 5' T12 fluorescent
Anyone actually done it for ancient electronic ballast versions?
My carpenter tenants workshop is lit with the things:-) Sadly other wiring uses the conduit so it is not a simple rip out job. Plenty on Google but they are a bit shy about costs and stockists. -- Tim Lamb |

TBH I am not sure what you are asking. I have swapped loads of fluorescent tubes for LED tubes and bypassed the old ballast (electronic and magnetic) without a problem, there is no rip out and rewire. As for prices? I know some reasonable deals. Who have you looked at? -- Adam |

I think the 11/2" tubes are related to unobtonium and he has been substituting T12s. They might have been there since he took the place on in 1985. The fittings are ceiling mounted and joined in a continuous conduit run which apparently also carries other wiring. TBH I am not sure what you are asking.

CPC but I can't get my brain round what is needed:-( Most of the web comment seems to be American. Yes, lots of people have done it. What exactly do you want. With electronics the age these must be I guess the most reliable would be combined LED tube and driver plugged in to the existing fitting connections. There must be an incoming terminal strip to re-route a supply to the tube couplers. I suppose an interim approach might be to use the existing electronics and a presumably cheaper LED tube. Only going for a full conversion as these fail. More light would be a bonus! None of this is very far off the ground (old pig fattening barn so around 10') although difficult working above your head wearing glasses:-( Reroute the mains straight to the endcaps, use LED tubes that work this way, having built in drivers. You can leave a magnetic ballast in circuit if you must, I wouldn't with an electronic one. NT |

Sorry. Ignorance on display:-) The smaller tubes are slow/reluctant to start. If you buy led tubes then most just have live and neutral at one end and a short on the pins the other end. So its normal to wore live to one end and loop neutral through the other end and back to the end with live. That way the tube will work either way around. Mark the fitting as led only as a normal tube will go pop. You can do exactly the same by replacing the starter with a short and leave a choke ballast in circuit. It probably won't work with an electronic ballast. |
