have hooked up balast for single tube fixture. Works except for occasional cold mornings. Calls for one disconnect type lamp holder. How critical is this? Thanks.

It probably doesn't light when it's cold beacuse fluorescent fixtures with magnetic ballasts only work down to about 40 degrees f. If you want it to work in lower temperatures, change the ballast to an electronic model and change the lamp to a T-8. That setup is good to about 0 F.

The cutout lampholder keeps the pins on the fluorescent tube from arcing to the fixture case when you change the lamp. The "cutout" disconnects power from the ballast unless there is a lamp in the socket. It's best to have one, but the fixture should work regardless.
