This is my opinion: Ordinary machine light bulbs are not expensive to replace; however, if the machine is not computerized, I don't think it's a big deal to turn the machine on/off frequently. LED replacement lights are very expensive and mine have to be ordered and installed by the dealer (costing time and money). Because the machine with the LEDs is computerized, I leave it on during the entire time I'm going to be sewing each day; when I think I've done all I'm going to do for the day, I turn it off and unplug it. While it's on, I have it set to where the lights go out and the screen goes black after 5 minutes of not using it.
