I’m not sure if I’m adding anything new here, but the wall wart appears to be a ballast which traditionally drives fluorescent tubes. There are led tubes you can just plug into a light fixture or lamp with a ballast, there are also ones that want you to rewire the lamp and remove the ballast. I won’t be able to help on rewiring as I’m in the US on our special voltage and I’m not qualified to be giving advice on that here much less anyplace else. There is another type of tube that can operate both with and without ballast (after a rewire).
The first step would be to ensure the tubes you’ve got are ones that need the ballast to work, it should say on the product page. In the US they refer to these as type A, the ones that work without ballast as type B, and ones that work with both as type AB. I’m unsure if that is the same elsewhere, but I do notice the “AB” in your picture, so that may be the case, but you would need to confirm.
If it works with ballast you could replace the old ballast with a new one, which is easier and safer than the alternative, though you may struggle to find one that fits where you want it to and they are less energy efficient. I have no experience replacing ballast, so I can’t help you there, but it may be as simple as getting another ballast and wiring it in. You can probably get a brand new one as they do wear out over time and need to be replaced.
If if works without ballast, since you’ve already removed it, it may make sense to rewire the lamps for the LEDs to run directly off of main voltage if the tubes are made for that and if you can find the resources to teach you how and you have the ability to do so safely. The lamps can be wired differently and the led tubes can require specific wiring. Its not the most dangerous thing you could do with electricity, but its got a lot of room for personal harm and fire if something is done wrong. I’ve done it without incident, but I’ve also rewired my home, adding light fixtures, a new circuit breaker box, and a heat pump, and had it inspected/approved by the local authorities, so I was pretty confident in my abilities. I don’t think its that hard to do safely in comparison to those other things, its just important to be very sure of what you are doing with electricity. Sometimes things can work but are incredibly dangerous still, other times they might blow up in your face. It takes years of training to be an electrician for a reason, you don’t get to make many mistakes more than once.
Also please don’t open up the transformers or ballast, they aren’t safe without the shielding they come with.
Good luck and stay safe.
I disagree, I don’t think humans are, as a whole, shitty. Most people are willing to do good when faced with a moral decision, even one they stand to gain from. Its just the ones that make it into seats of wealth and power aren’t part of that majority, so we see and hear about these awful people far more than the millions of good people all around us.
In a community as wide reaching as the internet there are going to be people looking for personal gain over others and they make everyone else withdraw. I don’t think you could ever have a gathering of millions, with some actually representing corporate profit motives, and freely share without risk. But not because everyone in there wants to stab you and take your money, but because a few do and you have no idea who some of them are and one of them is Jeff Bezos and he pays you.
