fermenter bin in dark?

Light is not an issue worth worrying about until it comes to storing the finished (maturing) product, then brown bottles are best although you will get away with clear/green if you are going to store them somewhere dark.

They may be affected, but having said that I've experienced no problems so far with 8 kits in ambient day light conditions in my utility @ 22 degrees.

Have a friend who has been brewing (kit and extract) for fifteen years when I visited recently he had seven brews on the go in ambient daylight.

Having said that John Palmer describing skunky beer refers to UV as being a problem alright...

[FONT=Verdana, Arial, Helvetica, sans-serif]Skunky
Skunky or cat-musk aromas in beer are caused by photochemical reactions of the isomerized hop compounds. The wavelengths of light that cause the skunky smell are the blue wavelengths and the ultraviolet. Brown glass bottles effectively screen out these wavelengths, but green bottles do not. Skunkiness will result in beers if the beer is left in direct sunlight or stored under fluorescent lights as in supermarkets. In beers which use pre-isomerized hop extract and very little flavoring hop additions, the beer will be fairly immune to damage from ultraviolet light. [/FONT]

however he makes no reference to storing the fermenter in a dark place in chapter 1 "A crash course in brewing"
