Camera Flash

I'm using a camera module to take pictures and send them to a server. The images are taken on a schedule - but sometimes the conditions become a little too dark and I'm not always around for example to turn on the lights. So I want to add a very bright light to my device that I can turn on right before the image is taken (like a camera flash) to illuminate the area sufficiently.

Does anyone have any recommendations for this? My device is taking pictures of a small room (range is about 2.5 meters) and is directly aimed at a grey wall. During the night this room would be pitch-dark so it needs to be a pretty strong light.

What kind of light? AC 120 / 240 V, DC 5, 12, 24 V? How long does it take for light to come up to full brightness after turn on, 1 sec, 5 sec, 50 milliSeconds? What is the wattage?

Night vision cameras usually use invisible (for humans) infrared light for this. You don't want the neighbours to ring the cops every time they see lights flashing in your house in the middle of the night. Look on ebay for IR flood lights, or make one yourself with IR LEDs. Leo..
