Fluorescent Wiring

Cmar-Ireland

Hi folks,

I salvaged an old circular magnifying lamp that was destined to go to the dump. It uses a TL-E 22W fluorescent lamp. The problem is that the switch is missing (probable why it was thrown out) and all that's left are the wires.

In the attached pic, you can see the black and brown wires coming from the lamp arm, and the brown wire is connected to the white wire on the ballast. The black wires and both red wires are not connected to anything and I assume they were connected to the switch.

What I would like to do is wire it up so it's switched from the socket and have no switch on the lamp itself.

Can any of you tell me how to connect the wires in this way?

Thanks!

would you consider stripping out the old flourescent and put in led ribbon lights

like these but i think you will get them here for less(you will need a power supply also)

Just bought a new tube for it so I'd rather use it. I had thought about LEDs but I'd rather keep the lamp standard. It's an old model, kinda vintage so I was hoping to keep it that way.

Looks like this, but bench mounted instead of floor-standing

A basic lamp circuit is shown here

Your choke/ballast doesn't look great in the photo, you may need to replace it too.

@ Brightspark,

So if I join the two red wires together and join the two black wires, then it should work?
The two red wires would have originally connected to a switch?

where is your starter?

Have another look at the link I sent.


I can't tell which wires to use from your photo, but as pyromania said you probably should have a starter somewhere in the circuit


this site may also be of use to you

(the wiring of the ballast isn't as clear on that page, but it shows the starter a lot clearer)

The lamp doesn't appear to have a starter anywhere or space for one?

What if I removed all the old wiring and ballasts and replaced it with this



Would this work?
the circular lamp in mine is 22w.
