Hi,

I installed the LED over single T8 bulb, now I see that the light is blinking due to surface agitation.

Even my moonlight is blinking...

It's OK? It won't stress the fish?

Thanks

What do you mean the light is blinking?

Are the LEDs actually blinking, or is the movement of the water surface causing what appears to be blinking?
Not the LED, movement of the water surface.
I have 2 HOBs and the water movement is pretty strong.

Don't be a baby! :)
LEDs, Metal Halides, and sunlight will all refract light like that.
I like it up to a point! If it bothers you, decrease your surface agitation a little.
I don't mind some shimmer but some tanks at a LFS literally look like they are flickering on and off.

Even my 4 bulb T5HO had a bit of shimmer with a different outflow than I have now because the lights were raised so high. It didn't bug me but it would have if I had LED's.

All kidding aside, I run 6 15 watt Bridgelux LEDs on my 65H, and the shimmer is a bit excessive. I have my continuous WC dripping into the tank, causing it.
