Default How much light to skunk a beer?

This question has popped up in my mind the last two bottling sessions, probably because of the placement of the windows in my kitchen. How much light does it take to skunk a beer? Can 5-10 minutes of direct light exposure do damage? Also, does darker beer have more resistance to skunking, just like melanin in a human's skin?

I don't think some light here and there can hurt it, it's consecutive hours of sunlight that will start to turn it. Correct me if I'm wrong but artificial light shouldn't have a negative impact on beer in bottles unless for a lengthy duration. I think it is an over cautious method by commercial brewers, but then again some of those beers can sit for quite some time before being drank. If there is a definitive answer I would like to know to.

To the OP- skunking can happen fast. http://www.homebrewtalk.com/wiki/index.php/Skunking
I have read that darker beers are slower to skunk (probably reflect more of the relevant wavelength) but they can go too after long exposure.

I'm looking for an opaque beer glass so I can drink my beer outside. It seems to skunk pretty fast in the glass if I set it in the sun and I spend alot of time outside.

So to anwser your question, not alot of sun, not alot of time.

Yes,
I can skunk a beer walking from my backdoor to the pool -25-30ft during the day. Blond beers are faster to skunk.

I had a Yuengling skunk in my hand while drinking it outside at a wedding a couple weeks ago. Took about 5min.

I find it hard to beieve that a beer is gunna get skunked in the matter of seconds it takes to walk 30ft. Ime,it takes quite a bit longer to actually be able to taste it. Maybe hop bitterness or flaws showing up as the beer warms in the glass. Especially if it isn't that chilled to start with.
But I've never skunked a beer 15-20 seconds flat. More like at least that they taste like shizz when warm.
