Power supply for led fixture

[kiyev]

Hello,

my cousin gave me a led fixture for which the power supply is no longer working. He threw it away so I cannot look at the specs there. He says he measured 78v out of the power supply before throwing it away, but he did not sound convincing.

In the pictures attached you can see the whole led fixture and the specification found in the fixture.

It says SD-8193-01 12*750 20/2 in each row. Each row has 20 led (10 white + 10 blue) for a total of 40 led in the whole fixture.

I also attach a video with the behaviour of the led fixture attaching a led driver I had with output 36V-68VDC 300mA.

It blinks, but it should remain lit. Maybe amperage of this led driver (300mA) is not enough?
I was considering that maybe the 12*750 means 12v and 750mA, but it seems unlikely to me. Any idea?

The video link is not correct and the forum does not allow me to change it.
This is the correct video link:

Hi,it is difficult to work out what the 78V was,if he threw it away afterwards...
They would seem to be displaying symptoms of an under powered driver,but without more detail,it is hard to say.

I have Googled "SD-8193-01 12*750 20/2" but no led strip came up... Maybe its just me doing it wrong.
What is the manufacturers name of the strip?

I googled it too with the same result. I don't know the manufacturer's name as it is not written anywhere in the fixture.

sounds like a constant current driver. i had exactly the same problem. got a new driver max volts 75V. no work right. replaced with a 90V max. output voltage. perfect result. see here. post #9 helped me sort it.
