The LED has to actually “listen” to the incoming power, reverse-engineer what the dimmer is trying to do, and set LED brightness accordingly.

Why does adding additional lights to a series circuit cause each light to get dimmer?

The bulbs are dim for two reasons: The current going through them is smaller because two bulbs in series have a higher resistance than a single bulb. Each charge only gives up some of its energy in each bulb, i.e. the p.d. across each bulb is smaller.

Why do LED lights dim then brighten?





The load balance changes when you turn lights or appliances on or off. That’s why you may see that a light starts dim and then gets brighter. An open neutral is an unsafe situation that you need to correct as soon as possible.

Why is one of my LED lights brighter than the other?

What exactly makes one brighter than the other? There are a massive array of factors affecting LED brightness including quality of LED, color, human perception of that color, CRI, drive current and voltage, thermal dissipation and driver efficiency.

How many LEDs can I put on a dimmer?

Varilight recommend putting no more than 10 LED lamps on one dimmer module. You can put multiple lamps on one plate, so if you have a three gang dimmer plate you can put thirty LED lamps on the plate in total (10 on each module).

Why does the bulbs become dimmer when you add more bulbs in a circuit?

When we add a lamp in series, the resistance goes up. This reduces the current and the lamps are dimmer.

What happens to the brightness of the bulbs connected in series when more and more bulbs are added to the circuit?





As more and more light bulbs are added, the brightness of each bulb gradually decreases. This observation is an indicator that the current within the circuit is decreasing. So for series circuits, as more resistors are added the overall current within the circuit decreases.

How do you fix LED ghosting?

3 options here:

  1. Change the LEDs to an approved product- may not solve the problem.
  2. Change dimmer to the PD-6ANS- most likely would solve or at least reduce the “ghosting” you are experiencing.
  3. Try the LUT-MLC- lots of posts on this, Lutron reluctantly has mentioned the MLC with dimming now.

Do dimmable LED bulbs need a special dimmer?

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.

Can you dim multiple LED lights?



This is something that many people ask when buying LED lighting. Can I dim a LED bulb? The answer is simple. Yes you can dim LED, but not all LED bulbs are dimmable.

What happens if you overload a dimmer switch?

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. Here’s how to avoid this happening using only some simple math. The majority of dimmer switches are rated for 600 watts.

Can a dimmer switch control more than one light?

With a standard single-pole dimmer, a single switch controls the light. With a three-way dimmer, you can control a light with two switches. You will need a three-way dimmer and a three-way switch. This lets you dim from one location and turn the lights on and off from another.

What happens to the brightness when you add more bulbs in series?



Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. In a series circuit, the voltage is equally distributed among all of the bulbs. Bulbs in parallel are brighter than bulbs in series. In a parallel circuit the voltage for each bulb is the same as the voltage in the circuit.

What happens when you add more components to a circuit?

In a series circuit, the total resistance across all of the components (the ‘net resistance’) increases as more components are added. The two resistors have the same current through them. The potential difference across them will be different if they have different resistances.

What happens when you add a second bulb to a series circuit?

The effect of adding a second bulb in series is to increase the overall resistance of the circuit. The resistance previously provided by the thin filament wire of just one bulb is now doubled due to the presence of two. This increase in resistance reduces the drift speed of charged particles everywhere in the circuit.
