I've recently acquired a UMAX Astra 1200S. The scanner seems to work fine
under SANE as far as the software goes (great job, guys!) but I've got one
question about the hardware.

When I connected power (and nothing else) to the scanner, the imaging
lamp came on. When I connected the SCSI cable, the lamp stayed on.
I've tried SCSI bus resets, scanning images, setting every available
option in xscanimage and scanimage, and never has the lamp been off.
The lamp is still shining under the scanner cover to this day.

Is this normal? Are the Windows drivers able to turn the lamp off?
Is the hardware incapable of turning the lamp off? Is it some kind of
funky solid-state lamp with a 100K-hour lifetime?

If I seem paranoid it's because I'm too used to color-balanced imaging
lamps on other photographic devices which have lifetimes less than
100 hours.

/proc/scsi/scsi contains (among other things):
Host: scsi0 Channel: 00 Id: 06 Lun: 00
Vendor: UMAX Model: Astra 1220S Rev: V1.3
Type: Scanner ANSI SCSI revision: 02
