While I realize the controller has an LED backlight, I have found ranges of lifetimes for such items. Was not able to specifically find anything about what Logitech claims for the Duet. Wondering whether leaving the clock on for most of every day is really a good idea or not. Any info?

Thanks,
Norm

Bump. I think this is a good question.

The backlight is specced by its manufacturer for a minimum lifetime of 50,000 hours... but frankly I'd be quite pleased if _I_ ever manage to outlive an LED.

I'd be interested to know this as I use mine to constantly show the analogue clock (well, when it's not showing the firmware upgrade screen anyway). I have begun to worry that I might be shortening the life of the device considerably.

Let Edit: Golly! Well that's fine then. I'll stop worrying.

I'll send you a couple of my 4W GU10 LED bulbs then, I've managed to outlive quite a few of them....

Thanks. I used to think the same thing, then I bought a two pack of LED nightlights from Walmart. Despite supposedly lasting "indefinitely," they both became noticeably darker after only a couple of weeks, and this trend continued until they both ended up quitting after only a few months use at night (i.e., in less time than a conventional nightlight bulb would have lasted). Obviously cheap Chinese crap, but makes me rather leery about blanket claims for LED lifetimes.
