HELP… Modify double ended T8 led fitting to use single ended

Hi.


We've been sent a dozen t8 fittings that accept the double ended LED tubes - there is no ballast.
We need to modify these fittings so they'll work with single ended LED tubes.
We run a vertical urban farm and we desperately need to get crops under lights so it would be great if anyone knows how to solve this.


Ive attached photos of both ends and the middle - hope you can help.

Hi Rob-Let's go about it this way:  First, disconnect all of the existing wiring. Before reconnecting anything we need to make sure the sockets do actually have two connections each.  Some of those sockets have both pins tied together. Use an ohmmeter to make sure that the two pins going to each socket are not shorted together.   Let me mention that it's odd that all of the existing wiring is white.  The wires are usually color coded; black and white for the US, and brown and blue for the EU (and others). The middle wire on the terminal strip is ground. Connect the top wire on the terminal strip to one pin of each socket on one end of the light fixture.  You may have to use a wire nut so the wire can go to to both sockets.  Connect a wire from the bottom of the terminal strip to the OTHER pin of each socket on the same end of the fixture where you connected the first wire.Before you connect power to the fixture, use your ohmmeter again to make sure the top and bottom terminal strip wires are not shorted together. If they are not shorted, connect the power wires, install the LED tubes, and turn on the power.  If you are at all uncertain about any of this, please find someone who is knowleageable to come by and work on it for you.  don't take any chances.-Rick  

It looks as if you have one mains wire going to one end and the other going to the other end which makes sense for double ended tubes. But how are the two wires that go from one end to the other connected?In any case, Rick has given some good advice.

HiDepending on the LED "tube" you need to be careful. Majority of LED tubes I have came across have their a/c input at only one end with the opposite end a short circuit between the pins. Check if this is the case for you.
It is easy enough to just strip out ALL internal fittings of the light (ballast / electronic ballast etc) and rewire to suit. If however you just take the power to one end of the fitting then you have two issues.1) The LED has to be inserted correctly to allow it to work.2) If you don't insert it correctly (the wrong way round) the short circuit will trip your circuit breakers.We have four connections in the fitting, two at each end as below.1                        32                        4
If we now connect connections 1 and 4 to the incoming A/C supply, then connect internally connector 2 to connector 3, then it does not matter which way you insert the tube.Regards
