What make fluorescent bulbs flicker?
A fluorescent tube will flicker is the temperature is cold or the fixture has a bad ground to the electrical system.
Why won't fluorescent lights come on all the way and what can you do about it?
Two of the main reasons fluorescent fixtures won't work is the ambient temperature is too cold and the other is the fixture is not properly grounded.
Could there be a strobe effect with fluorescent lighting?
Yes, it usually happens when the tubes are cold. As the fixture and tubes warm up this effect disappears.
Why fluorescent lamps not used on streets?
In colder climates a special ballast and lamps have to be used. These are known as cold start ballasts. The cost is much greater using fluorescent fixtures than HID fixtures and the light output is much less.
Is there such a thing as light without heat?
The fluorescent lighting is considered cold, but it is not totally correct.
Why does a fluorscent light not work in the cold?
fluorescent bulbs have mercury in them. There are heaters at the ends of the bulb that vaporizes the mercury to allow the light to be produced ( the fluorescence on the inside of the bulb is what actually glows). If the bulb is cold you do not get the ionization of the mercury to cause the fluorescent powder inside the bulb to glow, or it just glows a small amount.
Is there a special type of fluorescent light for cold conditions?
Normally its the ballast that's different. Use an electronic ballast rather than a magnetic.
Can use a motion sensor with dimmable fluorescent lights?
They can, but you need to have a motion sensor/system made for them. They require a ballast to get them to start (in most cases) and don't turn on instantly, making them a poor choice for most security applications. A motion sensor is just a switch so you should have no trouble with fluorescent lights. Older tubes sometimes take longer to fire, try relamping. If the fixture is outside and cold this has a major factor on operation. For outside fluorescent fixtures in real cold climate you need a zero degree ballast. The new electronic ballast are the best as they operate in all kind of temperatures.
Can you use fluorescent bulbs outdoor?
Can??? Sure, you'd just need to come up with a waterproof enclosure.But the problem is, many fluorescent fixtures don't work well when the temperature drops. Yes you can use fluorescent fixtures outside, they should be approved for the purpose and make sure they have 0 degree rated ballast for cold weather starting. The new electronic type ballast work in cold weather with no problems.
Why compact fluorescent bulb doesn't work well in cold weather?
Fluorescent lamps contain a small amount of mercury that must be vaporized to allow current to flow through the lamp and cause it to light up. The colder the lamp, the more mercury is in liquid form and not vapor form, causing a lower light output in the lamp.
Where do you find the wattage rating of a light bulb?
On the end of any light bulb except for the fluorescent type there are numbers on the end of light bulb. The number will be followed by the letter w I.e.(65 w). W represents watts-amount of power used. On fluorescent light bulbs the curly cue ones it will be around the base where it screws into the socket.
Coolant level is ok but the temperature light is on when cold start?
Answer: My brilliant cousin reckons when you first turn the key on and start it up, it just tests whether the temperature light is working.
