Why are my led lights not bright?

There are two reasons for this

  1. Poor line contact; 
  2. Insufficient power supply to the drive power supply.

Treatment method:

Check the line of the lamp to see if there is any contact failure and correct the line.

2. Regarding the lack of power supply to the drive power, you can find a professional electrician to repair or replace the LED drive and replace the power supply.

LED and other maintenance methods:

1. Pay attention to install moisture-proof lampshade to prevent moisture intrusion.

2. About cleaning: Just wipe with a dry cloth dampened with water. Do not wipe with a damp cloth after powering on.

3. Can be used in the circuit of dimming table lamp, delay switch, and sensor switch.

4. The ambient temperature is 5 to 40 °C.

5. Non-professionals cannot load and unload the assembly themselves.

6. Do not use chemical maintenance at will. The dust behind the lamps should be cleaned with a dry cloth.

Why do LED bulbs flicker? I have recently replaced incandescent light bulbs with LED bulbs. These LED bulbs are located in the bathroom. There are 4 LED bulbs in total. The incandescent light bulbs never flickered or dimmed by themselves. It seems the LED bulbs will flicker and dim every now and then. 

I have the LED lights on a dimmer. The LED bulbs dim perfectly with the slider dim switch. The LED lights are brighter and more efficient but the occasional flickering is making me think there is a problem. Can you advise what I can check or do?

Most common reason LED lights flicker:

LED light bulbs may flicker or dim in your home when there are voltage fluctuations in your homes wiring. There is an electrical current flowing in the homes wiring and the resistance of each wire uses some of the voltage when other things in your home are switched on and running. For example, if you run your washing machine and the clothes dryer at the same time, this is most likely why you will see an LED light dim or flicker. When electrical loads turn on and off in your home, this change in voltage levels will cause the LED lights to occasionally dim and or flicker.

Surge wattage from appliances in your home:

Certain appliances in your home require more power when they initially turn on. The name for this is “surge wattage”. When this happens there is a large drop in voltage. When surge wattage occurs, the power drain can make the LED lights dim or flicker. A solution to this is to put all appliances on separate breakers as this will lessen the surge wattage. The dimming or flickering of LED lights will probably occur no matter what. You may see slight flickering with LED bulbs no matter how your home is wired.

Loose wiring or loose LED bulb:

You may have a loose connection in the circuit. Screw the LED light bulb in tighter to try and fix the problem. If heavy dust is present in the light fixtures, blow out the connection points to remove the dust. There may also be wiring at the connection point that is loose. Disconnect power to the circuit and re-tighten the wiring making sure it is tight and secure.

LED lights are on dimmers:

If you have the LED bulbs on a dimmer switch, you will notice the dimming and flickering MORE if the LED lights are slightly dimmed when surge wattage happens. For example, when your central air conditioner clicks on, you will notice the LED lights dim or flicker slightly because of surge wattage. If you have the dimmer switch all the way up, you may not notice the dimming of the LED lights when surge wattage occurs.

Dimmer compatibility with LED lights:

Some light switch dimmers may not be compatible with all LED lighting. Check to be sure the dimmer switch is compatible with the LED light bulbs.

LED light compatibility with dimmer switch:

Some LED light bulbs are not dimmable. Find the LED bulb packaging and be sure it says “dimmable”. If the bulbs are not dimmable, put in a normal light switch or purchase LED bulbs that are labelled dimmable. If you are using ultra cheap and low quality LED bulbs, you will notice the flickering and dimming even more. Buy high quality LED lights that are marked “dimmable” or “compatible” with all dimmer switch types.

Unfortunately, there’s no easy answer. Diagnosing LED dimming issues isn’t all that unlike diagnosing a sickness.

You start by checking vitals before looking at the symptoms of the issue.

In a dimming scenario, the vital check is pretty simple

Are these lamps in fact dimmable led lights​? Are they compatible with the controls they’re being paired with? And are those controls still in working condition, or have they surpassed their life rating?

In medicine, the symptom of coughing does not always indicate that a patient has contracted a common cold. In fact, very few symptoms have direct, exclusive correlations to underlying cause. And it’s important to note that dimming issues are similar. Different problems share similar symptoms, making it awfully difficult to diagnose the cause. (The good news is, we know a handful of cure-alls when it comes to this stuff.)
