Yea. Those cheap jobs don't work when it is cold. They also tend to
stop working after being exposed to moisture for a while (the contacts
corrode), they tend to hum and they are not very efficient.
You need something that is cold weather rated. Even better would be
something that has electronic ballast as well. Best is both of them plus
Today in the US I have seen three options that fit your needs and easy
to find and are not too expensive. The first are the cold rated 8 foot
fixtures. They are what I have. However more recently I have seen some T8
cold rated fixtures that are 8 foot but use four 4 foot lamps. I believe
they also have some four foot (two lamp) matching fixtures. I may try them
when I get the time to replace the second half of my garage lamps.
The best quality fixtures are going to be available in a commercial
lighting supply, not one of the big box DIY centers.
Note: T8 is a smaller lamp the ones you are use to seeing are T12s. In
general the T8s work better in the cold, but be sure to get cold rated
fixtures as not all T8s are really designed for cold.
