I have a Pfaff 7570 that I have had several years (10 or more) and I leave my machine on for hours at a time. The only time I turn it off is when I am done for the day. I have replaced my bulb 1 time. Yes, it was expensive (over 7 bucks at the time), but I have also replaced other machine blubs with the same type of bulb used in the auto industry.... They are the same type and work just the same....

I can't find in my manual if the screen can be put on "screen saver mode" but if I push several different buttons within the menu I can turn off the lights to the needle area and the work area (separate buttons and yes they are the very expensive halogen type--really tiny too). It sounds like it is better to just leave them on anyway so I won't worry about that anymore.

Check "Myth Busters" about this. I know they did a show about it some time ago. froggyintexas
I don't know about sewing machines, but my dh told me turning the regular light bulbs on and off is harder on them than leaving them on. I would definitely not be turning my machine off and on several times over a 2 to 3 hour period.
Why so concerned about the sewing machine light? I would just purchase a spare or two as "security" and use the sewing machine normally. I have a Bernina 1230 that must be close to 15 years old and have left it on overnight once in awhile. I suppose one would call my usage of it light to moderate, since there were several years when I didn't do much sewing, but the light bulb is still going strong! Haven't had to change it yet. As for energy consumption, I should think that is at most a few pennies per hour. Years ago I figured out the energy requirements of a tv left on for 24 hours, and I think it was something on the order of 25 cents per day! (Edit: I think my memory on that was wrong. I think I amortized the cost of the tv over its life, and *that* came to 25 cents per day. Not that I'm an authority on that subject......)

I agree, and I think in a computerized machine it would be harder on the motherboard to keep sending that first blast of information through the circuitry. I know when I was a PC tech back in the 90's we believed it was better to leave the PC on than to turn it off and on frequently. Think of herding a bunch of cattle through a narrow gate, there will be a lot of stress on the walls, a circuit board is similar. The computer in my living room (also a media center) stays on all the time. I turn off the sewing machine and the PC in the sewing room when I am done for the day.
I have a 10 year old computerized Janome, and have never noticed the machine itself getting hot by leaving it on all day. I'm thinking the newest sewing machines would not have a "burn in" image issue on the screen, just like new monitors do not.

If I have changed the settings for any reason, I leave the machine on just so I don't have to remember what I have done. I think about the bulb once in a while but in the 40+ years I have been sewing, I think I have only had 1 light burn out. So unless I am leaving to go onto another project, the machine will probably stay on.

I leave mine on for duration of my time in the sewing room. One thing about computers - they say turning them on and off is not good because it causes the circuit boards to heat up - then cool down - then heat up again, and light bulbs similarly, you can do more damage with the on-off every few mins than leaving it on. And every time you turn it on, it goes through a programming phase - and I would think (and do) if you are gong to use it soon, leave it on until you call it quits for the day. :-)

I have a 19 year old pfaff, ofcourse not computerized.
I have to adorable shepparddogs to, who love lying around my feet and use the pedal as a pillow.
So I turn off and on the electricity a lot ( and with that the light) while working , I only had to chance the lightbulb once.
But it's a very cheap one for my pfaff so who cares????

Just because a machine doesn't have a computer doesn't mean it's not electronic. If you turn the machine on and off with a switch it has electronics of some kind. Mechanical machines just have a motor and a light switch.
