The driver for my LED lamp was broken and I ordered a new one online. Here you can see the specifications of the old one: enter image description here

I tried to match these specifications as good as possible and bought the following new driver: enter image description here

After connecting my lamp to the new driver it turns on for a split second and then stays off for 2 more seconds periodically.

Here you can see the specifications of my lamp: enter image description here enter image description here

Did I buy the correct driver for my lamp? If not, what driver should I use such that my lamp is working without flashing.

I'm happy about any help!!

So I told my father (it's his LED light) about the flashing of the lamps with the new power supply and he told me that with the old power supply he had the same problem (before he told me it was just broken). Moreover I told him then to check the old power supply together with the electrician in his company and they found out it works fine. So the problem should not be the old power supply. Sorry for the confusion! I will now check if there is a problem with the LED lamps as for example @dandavis suggested in the comments.

Thanks to everyone for the usefull tips :)

You can use some diodes to drop the voltage as well, use something rated at least 3 amps and if it works it could be a permanent fix. Be sure they do not get to hot. If you look at the current curve of a LED the current rises almost exponentially with the voltage once the threshold is reached. A few hundred milivolts the diodes drop will noticeably reduce the current. Your driver puts out 1500 (1.5 Amp) Milliamps until the voltage reaches 12V. At that point it goes from constant current mode to constant voltage mode, which limits the voltage to 12 volts. They make switch mode converters that have the capability of CC/CV. They are not that expensive and would do what you want. They may be sold to charge Lead or Nicad batteries and allow you to adjust both parameters. Ohm's law says you will only get constant current or constant voltage, not both concurrently. You can also get another LED driver unit to replace the one you have.
