The flash torch on the n900 is a two LED flash, which has several modes. It can flash brightly for a maximum of .5s, with an LED current of no more than 320mA, or be in torch mode, at a current of no more than 50mA.
Exceeding these values may cause hardware damage.
It also contains a red indicator light, to indicate video is being recorded.
(See kernel source ./arch/arm/mach-omap2/board-rx51-camera.c for details)
