I leave my translucent white plastic primary and glass secondaries in my temp controlled 73 deg. basement bathroom. I have one 40 watt light that is on the vanity above the primary. I left that light on overnight the other day and I have a week old hefe in the primary and a 4 week old Chimay clone in one secondary. The secondaries, in my house, get covered by black 200 thread count pillow cases. The primary, however, is not shielded from the light other than the plastic. Should I expect this small amount of light to screw up my flavors in the hefe or should I RDWAHB.

F.A.Q.This is kind of a long running joke, but seriously, it will be fine.

Yes, well I am not worried so much about ruining, I am just curious if 8 hours of low intensity incandescent light will have a noticeable effect

You can expose beer to much, much more than 8 hours of light from an incandescet bulb without having any perceived effect whatsoever. The only types of light to really concern yourself with are sun light or flourescent light.

Well thats why I use only the one bulb down there. Plenty of light to get the work done, and not too much to be an issue. Anyone know if L.E.D. light poses a risk?

This should say 68 deg. basement. I leave the heater in there set at 73 however, the ambient is consistently 68 and the primary usually measures anywhere from 70-74

if the LED you use gives off ultraviolet light I think it would pose a risk

[stellarbrew]

Yes, many of the modern LEDs do emit light in the UV part of the spectrum. I would generally keep my beer away from LED light.

I accidentally left my fluorescent lights on in my brew bunker overnight where all of my beers were sitting in glass carboys. The fluorescent lights will skunk a beer, but the effect seems to be temporary. Once the beer sat for another week or so in the dark, the skunkiness faded.

It depends on the type of white LED it is. Most of them use UV LEDs and a phosphor-coated lens and do emit light at 530nm. The ones that use blue, green and red LEDs do not. To be safe though, I agree with stellarbrew that you should avoid exposure to LED light.

I thought I would do a quick search and found some information about beer and light and thought I would post some to read and comment as well.Article 1Article 2
