Best Answer

The bulb must be labeled as dimmable. If the bulb is an LED for example there is a circuit that transforms the 120 AC supply voltage to a DC voltage. This circuit needs to be able to supply a DC voltage proportional to the voltage required to operate the LEDs. In a dimmable bulb you might be powering the multiple LEDs selectively to achieve dimming rather than just reducing voltage to all LEDs over a very small voltage range in which an LED operates.

A dimmable eco bulb may not dim when controlled from a dimmer switch because it is not compatible with the type of dimmer switch being used. Some dimmer switches require specific types of bulbs or have specific voltage requirements that may not be met by the bulb. It is important to ensure that the dimmer switch and bulb are compatible for proper dimming functionality.

Can you use a dimmer switch with A19 incandescent bulbs?

Be it a tungsten or LED A19 bulb, both are usable with a dimmer switch. However LED bulbs require special dimmers to work correctly. Normal dimmers, those used for regular tungsten (incandescent) bulbs, use the resistive load of the bulb to allow dimming. Most LED bulbs require other methods to dim the bulb. One stop gap fix to use a regular dimmer is to add a small wattage bulb to the LED bulb circuit. That adds a resistive load to fool the older dimmer. The best option for dimmable LEDs is to ensure you have a dimmer that specifically states it works with dimmable LEDs.


Is there a dimmable CFL bulb that can be used with an electronic dimmer?

Compact fluorescent bulbs used to be all or nothing. They couldn't be dimmed. Most cfl lamps (bulbs) are this kind. However, special cfl bulbs are now being marketed, at a higher price, that can be dimmed by a normal dimmer switch previously used for incandescent bulbs. However, not all dimmer switches work with these newer dimmable cfl lamps.


What should you do if you installed a new light in an old house that uses a dimmer switch and now the light won't turn off?

Some lights won't dim. If you've installed the switch properly, and are using traditional incandescent bulbs (not flourescent, LED, E-L lights or any other very low current light), the dimmer will dim the bulbs. Make sure you're using a dimmable bulb and that the dimmer is installed properly.


Can energy save bulb be used with any dimmer?

Compact florescent do not dim. They are all or nothing. You can use them where you have a dimmer switch. They will come on from about half way to full on. Dimmer switches don't like them and the switch will burn out faster.


Why do dimmer lights not dim?

probably you have wired it wrong so look at the wiring diagram that is supplied with the dimmer switch and make sure your wiring matches................or..............................you have a energy saving bulb connected whih do not like to dim they will flicker

Why can't you dim fluorescent light bulbs?

Some fluorescent lamps (bulbs) can be dimmed, but they must be designed to be dimmable. The ballasts and electronics that drive the bulb have to be designed to work with a dimmer or they will not function properly and may overheat. When dimming fluorescent bulbs, many can't be faded smoothly from full to zero. Some will only go to a minimum like 5-20%. A dimmable compact fluorescent lamp will be labelled as being dimmble and can be connected to an ordinary dimmer. For tubes, the ballast has to be specailly designed to be dimmable.


What is the type of lamp uses with dimmer switch?

You cannot use most fluorescent lights with a dimmer. Just about any incandescent bulb WILL work with a dimmer. Occasionally, when a halogen bulb burns out, it will destroy a dimmer switch but halogen bulbs are considered incandescent and other than that little problem they work well with a dimmer.


Can you put a dimmer switch on compact fluorescent light bulbs?

I have but if dimmer is on low the light fixture sometimes "hums", can be anoying It also shortens the bulb life, significantly in some cases. But their are also CFL bulbs built to be used with a dimmer switch that avoid these problems.Another AnswerYou should only use CFLs specifically-designed to be used with dimmers in circuits controlled by dimmer switches. There is a proven danger of fire hazard when ordinary CFLs are controlled by dimmer switches and, so, this should NEVER be done.

Where is the headlight relay for 1990 pontiac sunbird le located?

On the '92 sunblrd SE the power for the lights to from fuse to headlight switch to dimmer switch to bulb, no relay involved.


Can a dimmer switch help reduce the use of energy in a home?

No. this is because a dimmer switch increases resistance to produce less light. in other words, the dimmer switch converts the electrical energy into other forms such as heat by increasing resistance and is thus not saving energy, but wasting it.


How can someone select the right compact fluorescent dimmable bulb?

To select the right compact fluorescent dimmable bulb, factors to consider are bulb design, light output & power consumption, color, and recycling options. It is important to use good judgement regarding these factors and how you plan to use the lamp in question.


Your 1997 Pontiac sunfire low beam headlights don't work but the high beams do?

Low beam bulb burnt out? Replace bulb. Bulbs OK? If the dimmer switch is also the turn signal/cruise/headlight on and off switch, you probably have to replace the entire switch.
