What Does This Mean?
We often take for granted how simple and convenient it is to flip a switch and have our lights turn on or off. But what happens when the lights suddenly stop working, and you’re left wondering why? Could it be the light bulb that’s burnt out? Is the light switch faulty? Or, worse yet, are the wires being chewed by mice? (Let’s hope not, because that’s a completely different issue!)
In most cases, the problem can be diagnosed and resolved without needing a manager or specialist to step in. Here’s a guide to troubleshoot common lighting problems and get things back to normal.
The 4 Main Causes:
The light fitting is unplugged
Sometimes the simplest explanation is the right one. Check to ensure the light fitting hasn’t been accidentally unplugged.The light bulb has burnt out
Light bulbs have a limited lifespan and may need replacing.The circuit breaker has tripped
A tripped breaker can cut power to the lights. You will not be able to do this so call the helpdesk or check to see if a the owners of the site are there to helpThe ballast or driver needs replacing
For certain lighting systems, the ballast or driver may have failed and needs to be replaced.
Additional Causes to Consider:
The light switch is broken
The switch itself may be faulty or damaged, preventing the circuit from closing.Loose or disconnected wires
Wiring issues, such as loose or improperly connected wires, could be causing the problem.
What Should I Do?
Step One: Locate All Light Switches
Do you know where all the light switches are located? In some environments, like pubs, there may be multiple switches scattered across different areas, such as behind the bar, in storage areas, or near entrances. Some may also have dimmers or sliders that control light intensity.
Ask yourself: Are you absolutely sure you’ve checked all the switches?
If yes, and the problem persists, move on to Step Two.
Step Two: Test Lights in Other Areas
Try turning on lights in other sections of the building. For example, if you’re working in a pub, check the lights in areas like the cleaning cupboard, kitchen, or storeroom.
Before you do this, check for emergency lights:
- Are any emergency lights on?
Emergency lights often activate when there’s no power to the main system. Keep in mind that in some venues, these lights remain on regardless of the situation. - Look for unusual lighting patterns. Emergency lights typically look different from regular lights and are designed to remain visible during power outages.
Pro Tip:
When observing emergency lights or backup systems, note any lights that are on but shouldn’t be—this could be a clue that power isn’t reaching the intended circuits.
By following these steps, you can systematically identify the root cause of the issue and decide whether additional help is needed.
