Right, so I've decided to make my own LED fog lights. I like LEDs, plus I need to have fogs outside the headlight housing so that I can upgrade my headlights soon and still have fogs.

I already know how I'm going to mount them and what-not (A recent thread gave me the last bit of inspiration I needed), but I'm having a good deal of difficulty finding how bright I should make them. In my opinion, brighter is better, but I was kind of hoping to have a benchmark to at least meet and hopefully surpass before I began ordering parts.

Does anybody know how much light a decent white (I'm looking for about 5500k-6500k color temp) fog lamp produces?
