Man, that’s a lot. Think about that a lightbulb fails most often when you turn it on. It’s because that’s when it’s under most stress. You’ve got the initial power surge and also the constant temperature fluctuation from cold to warm, which adds stress over time. You’re really not burning much electricity at all leaving them on, so you might reconsider.
As some supporting info, I recently had my McCormack amp upgraded at SMcAudio, and they believe in leaving their amps powered on so strongly that in the upgrade they disconnect the power switch completely so it’s just a dummy light, and to turn the amp off you have to physically unplug it. I’ve had my amp for 30 years and they said by leaving it on 24/7 (unless I wasn’t using it and/or was away for an extended period), I probably extended the life of my amp for years. FWIW.
