Driver felt down

MW driver felt down from 160 cm to floor. On the max, so it was hot. Is this any problem? Lights are normally working.
And another question, which was before it felt down. When adjusting wattage, light is blinking or how you say. Flickering? It doesn't go smooth from 100W to 300W, but it blinks. Is this any serious problem?

how old is the driver?
is it a cheap forign one?

Are you maybe using the voltage adjustment instead of current adjustment?

Driver is 3 years old. It's original MW driver.
It's constant current. I have two. One is not "flickering" and goes smooth from 100 to 300W.

Flickering on cc driver is usually a matter of insufficient voltage for the load.

What does this mean?

When youre leds are powered by a constant current driver which isnt outputting sufficient voltage, just under what is needed you tend to get a flickering effect. Cant say for sure if this is your case. Sounds like your driven is at least slightly broken. The other possibility is your cobs having lost some strings which could push up their forward voltage but i find that unlikely.

Is this normal at night (when lights off)? They just glow randomly, some at the end of strips, some at the middle...

If the lights turn off randomly, I suggest unplug , untighten connectors and try again. make sure ballast and light witch are powered on. If other lights are turning on like you said I would say it's possibly the dim switch if you have one turn it on and the one on to the ballast. You can try that and move on. Return it or contact support.

Could be related to your timers, seems like your drivers are drawing a little bit current. Make sure that your drivers are on a circuit which isnt pulling anything else: your AC connections must all go to an extension lead with nothing else connected. If you have fan and drivers on the same lead you can get this if your driver timers arent shutting out all the ac current.
