Does high humidity affect fluorescent lights? Exposing the bulb to moist air will cause these prongs to corrode, reducing the performance and life of the bulb. It is advisable to avoid using fluorescent bulbs in wet or humid areas, opting instead for a sealed incandescent, mercury vapor or LED light source.
How to fix a hard starting fluorescent light?
Do fluorescent lights need to be grounded?
Why do my fluorescent lights not come on sometimes?

As a result, wires begin rusting and eventually cause problems. Corrosion leads to loose connections that affect your light fixtures.
Does Weather Affect fluorescent lights?
Operating fluorescent lamps in cold or hot environments will lead to reduced light output, reduced power, and reduced efficacy, as shown in Figure 9.
What is the most common problem of fluorescent lamp?
flickering tubesThe most common problem with fluorescent lights is flickering tubes. In most cases, flickering fluorescents are caused by a problem with one of three things: the starter, the tubes, or the ballast.

Can humidity make lights flicker?
For example, the switchgear may corrode and rust due to humidity. Ultimately, your electrical gadgets will start malfunctioning. Additionally, electrical wires will rust, lights will flicker, and sensors won't work any longer.
Why does my fluorescent light take a long time to come on?
Some older lights may contain a module called a starter. This unit sends a surge of current to the tube when the light first turns on. Over time, the starter can wear down and ultimately take longer to do its job. Lights that take a long time to come on or flicker on and off without starting are common symptoms.
Why do fluorescent lights flicker when cold?
Flickering fluorescent lights can also be a result of temperature. If the air around the bulb is cold and circulating, the bulb won't be able to generate enough heat to work properly. The internal temperature of a fluorescent bulb should be about 50 degrees Fahrenheit for it to work properly and optimally.
Does cold affect fluorescent lights?
Temperature: fluorescent lamp starting and light output are affected by surrounding air temperature. Most ballasts will start standard lamps down to 50°F. Special electromagnetic ballasts for standard rapid start lamps will start lamps down to 0°F.
When should fluorescent tubes be replaced?
Typical lamp life for a fluorescent bulb is about 20,000 hours, but this can degrade as a consequence of frequent switching (turning on and off). Burning life is extended if lamps remain on continuously for long periods of time.
Is it safe to leave fluorescent lights on all the time?
In fact, fluorescent bulbs don't lose any “life” when left on for up to three hours. To understand why this is the case, you need to understand "burn time." Fluorescent lights have a coating of electrodes that allow them to work. The light burns off a small amount of those electrodes every time you turn it on.
Why do new fluorescent bulbs flicker?
Blinking can also be caused by a loose connection in some of the wires inside the fixture, or by a defective ballast. It can also be caused by low temperatures (below about 50 degrees) unless you have special low-temperature tubes and low-temperature starters.
What happens when a light bulb gets wet?
If the bulb is lit when you pour water on it, it will undergo thermal shock. Some parts cool down and shrink, while other parts are hot. This causes very large thermal stresses, which can break the bulb.
Are outdoor lights safe in the rain?
Outdoor lights can get wet as long as their IP rating is waterproof. To ensure your specific model of string lights can get wet, you need to look at the IP rating of your outdoor lights to check how well protected they are against moisture.
What happens if water gets into outdoor light fixture?

Fluorescent light and humidity - Ask Me Help Desk
My kitchen ceiling light is known to not work during periods of high humidity. Last year I replaced the sockets that the (2) bulbs get twisted into, and the problem seemed solved. However, during a recent about of high humidity, the two bulbs weren't working once again. Once the humidity subsided, it works. This now happens over and over this year.

I think @Sally Hindman is on the right track, we're in Denver, which is dry, but basements in the older neighborhoods we work in are usually damp with humidity issues due to the poor drainage around these 100 year old homes so our basement projects we never recommend solid wood or anything with any wood content due to the potential for mold growth or expansion/contraction due to changes in ...
How to fix a hard starting fluorescent light?
Dirty bulbs and/or dirty fixtures will cause hard starting, especially in humid conditions. Take out the bulbs and clean them with window cleaner. Clean the interior of the fixture with the same stuff, (MAKE CERTAIN IT IS TURNED OFF!) let it dry and reassemble. Things should work fine from then on. If they don't, you probably have old bulbs, wrong wattage or wrong type bulbs for the ballast, or a bad ballast (in that order). There are other possibilities, tkrussel covered another one, and the rest you don't need to know. Sorry I can't find the link to give the whole nine yards.
Do fluorescent lights need to be grounded?
Any fluorescent light fixture needs to be grounded properly, one for safety reasons, and, two, to operate properly. I suspect the fixture is not grounded that is causing your problem, the humiditiy being the indicator. The lamp starts by using the capacitance that exists between the lamp glass wall and a metal grounded surface.
Why do fluorescent lights need to be grounded?
Brand new fixtures can exhibit this problem. Also, make sure the fixture is grounded. Fluorescent lights need the ground because the metal light fixture is actually part of what helps establish the arc in the bulb.
How to fix fluorescent bulbs that fail to start?
