Fluorescent Light Dim Then Bright

Older fluorescent light fixtures that flicker or only light up part way may just need a new starter which is a less expensive repair than a bulb.

Fluorescent light dim then bright.

I have a fluorescent light fixture that uses two 40 watt 4 long tubes. Time to retire them and replace with leds. It s not the tubes as i ve replaced those and nothing changed. Someone suggested it might be the ballast.

When first turned on it works fine for a minute or two then one of the tubes becomes dim and the other becomes dim and flashing. Both bulbs are very dim but evenly lit along their length and both the same as each other. Consider the steps to fix the problem. When a light starts dim and then gets brighter the cause may be an open neutral wire.

Dim fluorescent light bulbs and bad lighting ballast fluorescent light bulbs that are allowed to burn out in the socket can actually cause the ballast to burn out and need replacing. There are several failure modes for fluorescent lamps that make them a pita sometimes. Most people choose fluorescent lights in order to save money. If fluorescent lamps start to burn out or flicker then it is time to replace them and always replace both lamps as a pair for a longer lasting ballast.

The starter is located on the lamp frame there are typically two starters. A good way to check that your ballast is the culprit is to turn on a voltage detector and hold it next to the wires supplying power to the ballast. The disconnect may be in the panel or it may be between the panel and the line transformer. Since it started doing this one time it lit fully for about five or ten minutes.

I tried reading. It has recently started acting strange. The utility company does repairs outside your house but if the problem is in the panel you need an electrician. There s nothing worse than having to be in a room with a flickering fluorescent light.

When you turn on the. You ve already gotten your money s worth buying into them so do it again with led replacements in the same form fact. You ll find replacement starters at any hardware store. This is one of the concerning problems with the fluorescent lights.

Found primarily in kitchens offices department stores hospitals and warehouses fluorescent lights waste less energy than incandescent lights and can save you as much as 40 percent on. One clue that your ballast is the reason for a non working fluorescent light is the light bulbs struggle to turn on. It feels creepy and can also cause a terrible headache. This morning they were completely dark at first but are now very dim again.

Is this a sign the ballast needs to be replaced.
