A: No. The majority of CFL bulbs sold today are not dimmable. A CFL bulb that cannot be used on a dimmer will have the statement “not for use with dimmers” or “do not use with dimmers” marked directly on the bulb. Use these dimmers to maximize performance of the lamp/dimmer combination.
Compact fluorescents cannot be dimmed unless they are a special type of dimmable compact fluorescent bulb. All regular fluorescent bulbs can be dimmed; however, if you try to dim one in an ordinary fluorescent fixture, you will encounter one or more of these problems: The lamp may not light.
Similarly, can you put a dimmer switch on LED lights? Well, the answer depends: Yes, LED lights work on a dimmer when: You have “dimmable” LED light bulbs. You use an LED compatible dimmer.
Similarly, what happens when you dim a non dimmable CFL?
Not for Dimmers A standard CFL bulb can’t be used in a dimmable fixture. If you try to dim a standard CFL, the bulb will flash, flicker or go out. The National Electrical Manufacturers Association warns that dimming standard CFLs will greatly shorten bulb life and may damage the dimmer switch.
Can a fluorescent light work without a ballast?
Reverted question “ Can I make a fluorescent light work without a ballast?” yes, you can, but you need something to reduce the current as the bulb warms up. So, you can drive a fluorescent with a pulse width adjustable power supply, but this is what is in an ‘electronic’ ballast.
What is the difference between a ballast and a starter?
The starter (which is simply a timed switch) allows current to flow through the filaments at the ends of the tube. Since the lighted fluorescent tube has a low resistance, the ballast now serves as a current limiter.
Should I dim my ballast?
As already mentioned, new lamps need to stabilize chemically before it is safe to dim them, so give them at least 100 hours of 100% power, before you run them at lower power settings. For MH lamps, you want to make sure to always start them at 100% and them dial down the ballast. Do not start them in a dimmed setting.
What is required to dim fluorescent fixtures?
Fluorescent fixtures are dimmed using a special dimmable ballast. This is because standard ballasts typically do not have the ability to maintain electrode heat to the degree required for proper gas excitation when input voltage is varied.
What causes ballasts to fail?
Causes of Ballast Failure Premature ballast failure is often caused by the surrounding environment. When it’s too hot or too cold, the ballast can burn or fail to start your lamps at all. Heat combined with prolonged condensation inside an electronic ballast can cause corrosion.
Why do my fluorescent lights hum?
Buzzing in fluorescent lights is caused by the ballast, also known as the transformer, in the lighting fixture. Most residential fixtures use magnetic ballasts that operate at 60 hertz, which creates audible humming and flickering. No more humming and flickering from your light.
Are LED fluorescent tubes dimmable?
Dimmable LED Tubes. The toggled D-series dimmable 16-watt linear LED tube light bulb is designed to replace T8/T12 fluorescent tube lights (120 VAC Only) to significantly lower energy and maintenance costs while enhancing the quality of light in work environments and living spaces.
Why do light bulbs hum when dimmed?
Dimmer switches work by chopping up the AC current flowing between the switch and the light. The interrupted current can produce a vibration in the electromagnetic field within the light bulb filament or within the switch itself, which can cause a humming or buzzing noise.
What happens if you dim a non dimmable LED bulb?
?If you install a non-dimming LED bulb in a circuit with a dimming switch, it will likely operate normally if the dimmer is at its 100% or fully on. Dimming the bulb, will likely cause erratic behavior such as flickering or buzzing and ultimately may cause damage to the bulb.
Can non dimmable LED bulbs be dimmed?
Dimming LED lamps can save energy and changes the visual appearance and mood of your space. You can use a dimmable LED lamp in a non-dimmable circuit. You should NOT use a non-dimmable lamp in a dimmable circuit as it may cause damage to the lamp and or circuit.
Can dimmer switches cause fires?
The most common fire caused by dimmer switches is putting too much power through them. CLICK HERE to read about a dimmer switch fire. Modern dimmer switches use slick internal electronics to dim the lights. These components can turn the light on and off 120 times per second.
Can you put a regular bulb in a dimmer?
Yes, you heard it right, one should never use normal light bulbs with dimmer switches because if you do so, the light will not perform well, it may appear fine in the beginning, but with time you will start noticing the difference in the intensity of the light.
How do I know if my LED bulbs are dimmable?
Look for an “LED” or “LED LAMP” marking on the bulb as well. Most residential LED light bulbs are dimmable, but some are not. In addition, the amount they can dim, or “dimming range”, also varies based on the light bulb used.
How do you buy a dimmer switch?
Choose a dimmer with a wattage rating that meets or exceeds the total wattage of all the light bulbs the dimmer will control. For example, if the dimmer controls a fixture with ten 75-watt bulbs, you need a dimmer rated for 750 watts or higher.
Why are some light bulbs not dimmable?
While a non-dimmable LED may perform well in a circuit with a dimmer switch (incandescent or LED) set to 100 percent, there is a chance the light will flicker and hum at other brightness levels. Also, it may dramatically shorten the life of the bulb. Smart bulbs are not meant to work with dimmer switches of any type.
