Lux sensor

[Rubenrav]

I'm looking for a compatible sensor that measures light intensity, but I've only seen sensors that can tell if it's light or dark, but I want to measure the lux value. I've seen this in weather station packages on ebay and on websites that sells industry equipment, but has anyone heard of this thing that can be used against telldus? I don't need to use it in a telldus software, only read the value and save to database by my self.

Have only seen 1wire or people that have repurposed temp sensors.
