What wattage heater do I need? heater size calculator.
A rule of thumb commonly used to calculate a load for LED dimmers is to divide the stated maximum load by 10. For example a 400W dimmer switch should have no more than 40W of LED bulbs connected to it, which would equate to eight 5W bulbs.
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.
Trailing edge dimmers work best with LED light bulbs and leading-edge dimmers work best with traditional incandescent and halogen light bulbs.
The dimmer switch is rated for the same voltage as the lighting application. Use standard dimmers on 120 line voltage and low voltage dimmers for 12V and 24V applications.
new jersey — Did you know that you can accidentally overload a dimmer switch? If you do, it can become hot to the touch – sometimes extremely hot – to the point where it can become a fire hazard. … If the total wattage of the bulbs being dimmed exceeds 600 watts, however, that’s when the switch will begin to overheat.
Standard household dimmer switches range from 150W to 1000W, so the highest wattage for a dimmer switch is 1000 wattage.
A standard dimmer switch cannot be used with an LED light as you will never be able to dim the LED light either completely or not very well. LED lights need their own special electronic dimmer switch to have a fully functioning and dimming light.
A dimmer switch can be installed anywhere that an existing on or off switch is in place. Replacing the current toggle switch with a dimmer switch will allow you to change the lights’ brightness, so long as you are using a light bulb that is compatible with the dimmer you have chosen.
Instead of merely turning lights on or off, get a wide range of light by installing a dimmer switch. Most dimmers are designed to fit a standard wall box opening, which makes it easy to replace the switch for any incandescent or halogen light with a dimmer.
LED bulb flickering can be traced in almost every instance to a non-compatible dimmer switch in the lighting circuit. … LED bulbs don’t have glowing filaments. When the dimmer switch goes off and on many times per second, the LED bulb becomes a flickering strobe light.
How does a Dimmer Switch work? … These switches are designed to work with CFLs, Halogens, and Incandescent light bulbs. But the bulbs need to be of the latest technology and must have the feature of dimming to allow it to be used with a dimmer switch.
So what happens if you use non-dimmable LEDs on a dimmer? Well, at best the bulb just won’t dim properly. … But non-dimmable LEDs are only designed to be either fully powered ON or OFF, which means the circuitry inside won’t be able to handle low or pulsing current levels and will eventually become damaged.
With LED lights the effect of dimming compared to power use is fairly linear. However, dimming incandescent is actually less efficient than using a lower wattage of bulb. For example, a 60W bulb dimmed to the brightness of a 40W bulb will use more energy than a 40W bulb on maximum.
You’ll need a screwdriver, wire stripper, inexpensive (2 lead wire type) voltage tester and needle-nose pliers to install a dimmer. Wiring problems and mistakes are all too common, and if left uncorrected have the potential to cause short circuits, shocks and even fires.
Electronic Low Voltage (ELV) Dimmers were originally designed to control Electronic Low Voltage Transformers used in low voltage (12V) MR16 type fixtures. ELV dimmers and transformers are more expensive but offer quieter operation, better control and tend to last longer than Magnetic Low Voltage Transformers (MLV).
Dimmer switches typically last 15 years. However, a dimmer can fail due to age, repeated use, or loose wire connections that cause them to short circuit.
It’s perfectly normal for a dimmer switch to be a little warm when your lights are on (or partially on). But if it’s hot, there could be a problem. Dimmer switches get warm because they have electronic devices inside of them to take care of the dimming.
A dimmer can only be a fire hazard if you fail to read and follow the enclosed installation instructions. I have installed dimmer switches for years, and not one has ever caused an electrical fire. The reasons dimmer switches get hot is fairly simple. Some dimmers get hotter than others because of their design.
A good rule of thumb is to allow 100W for each LED fixture so in this case, the 600W dimmer can handle only six LED fixtures. If you are meeting all of the electrical requirements of the dimmer and you are still having flicker issues, you can try adjusting the low-end trim.
Leading-edge dimmer switches are cheaper and simpler than trailing-edge, and were used originally to dim incandescent and halogen bulbs or wirewound magnetic transformers. They use a ‘TRIAC’ (Triode for Alternating Current) switch to control power, and are sometimes called TRIAC dimmers.
Electricity is a mystery to many people, but some electrical projects — like wiring a switch — are so simple that anyone can do them. With a few easy steps and the right knowledge, there’s no need to hire an electrician.
Dimming fluorescent tubes FYI, fluorescent lights do not dim well at all. … Furthermore, it takes the correct type of dimmer switch, like those made for incandescent or led lights won’t work with fluorescent lights and a fluorescent light fixture that’s rated for dimming.
When using a 3-way dimmer switch, you should only have one dimmer on the circuit. The other switches (you can have more than one) must be on-off switches only. In this setup, the light level is controlled from a single location, whichever light switch you replace with the dimmer switch.
Unlike standard switches, most dimmer switches have wire leads that are connected to the circuit wires with wire connectors, rather than using screw terminal connections.
Unlike incandescent light bulbs, LEDs don’t produce light using heat. This is part of what makes them so energy efficient. The downside is that their components can be sensitive to overheating, which can cause them to burn out prematurely.
- Always drive LED products using an LED power supply that’s designed for the job. …
- Make sure all your LED products are compatible with the control circuits and power supply you’re using.
- Check for loose wiring and other faulty connections. …
- Consider using a constant-current LED driver.
Minor changes in your home’s voltage are normal, but flickering lights may indicate abnormal fluctuations. Abrupt changes in voltage from low to high can damage electronics and in rare cases cause an electrical fire.
- Fluorescent light bulbs. …
- LED light bulbs. …
- Incandescent and halogen light bulbs.
Smart bulbs don’t work well with old dimmer switches as the bulbs already have dimming capability in them. The bulb’s built-in dimmer and the wall dimmer will interfere, making the bulb flicker.
Also, dimmer switches give you complete control over the amount of light in a given space. You can reduce the light output, which helps the light bulbs last longer. … As a result, dimmer switches can help you save on your utility costs and minimize the costs related to replacing the bulbs.
Yes, dimmers reduce energy consumption of dimmable LEDs. Unlike incandescent bulbs, the electricity used is fairly linear with the light output; at 50% brightness it should use roughly 50% of the power. Generally speaking, dimming will allow the bulbs to run cooler and extend their life spans.
