In an age where energy costs in South Africa continue to climb and Eskom load-shedding lurks around the corner, many homeowners are turning to smart lighting to curb energy usage and improve convenience. But there’s a surprising amount of misinformation floating around about smart bulbs—so much so, it might be putting people off the very solutions that could genuinely save them money. Today, we're busting some of the most common smart bulb myths affecting home energy savings, so you can make the most informed decisions for your household.
Key Takeaways
- Smart bulbs are far more energy-efficient than incandescent and many halogen bulbs.
- They don’t constantly use high amounts of power when on standby.
- Not all smart bulbs need Wi-Fi to provide energy-saving benefits.
- Using automation and scheduling can significantly reduce unnecessary energy use.
- Smart lighting works best when paired with compatible switches and systems.
Myth #1: Smart Bulbs Use More Energy Due to Standby Mode
One of the most common concerns we hear in conversation or online forums is that smart bulbs use more energy overall because they're always “on,” even when not lit. This extra power draw is due to their connectivity—usually via Wi-Fi or Bluetooth. But here's the catch: the standby power consumption of high-quality smart bulbs is extremely low—usually around 0.3 to 0.6 watts.
To put it into perspective, this is much less than the power used by older routers or even the phantom drain from regular plug-in appliances. Plus, the energy you'll save from being able to remotely switch bulbs off, automate usage, and fine-tune brightness far outweighs the tiny parasitic load when idle.
Myth #2: Smart Bulbs Won’t Work Without Wi-Fi, So They’re Useless When the Internet is Down
This myth stems mainly from confusion around how smart bulbs stay connected. While some models rely on Wi-Fi, many now also use Zigbee, Z-Wave, or even Bluetooth. Some smart bulbs can keep previous schedules active even if the internet drops temporarily. In short, your lighting won’t disappear into darkness during a bad connection.
To go a step further, combining smart lighting with devices like the Smart WiFi Switching Module can add another layer of control—allowing you to integrate smart bulbs into a wider smart home system, with built-in fail-safes and automation.
Myth #3: Dimming LEDs with Smart Bulbs Reduces Their Lifespan
Another big misunderstanding is around dimming. People worry that lowering the brightness of an LED will somehow shorten its life. The truth? The opposite is actually true. Lowering the light output reduces heat, which is a major factor in LED degradation. In smart bulbs, this can mean extending the lifespan from the average 15,000 hours to even 25,000 hours or more.
Top Tip: Set automation routines to dim your lights in the evening for better sleep and to prolong the life of your bulbs. Soft lighting also transforms your space into a cosy, inviting retreat as night falls.
Myth #4: Smart Bulbs Can’t Be Used with Wall Switches
This is part-truth, part-myth. Yes, turning a smart bulb off from the wall switch cuts power to it, rendering the "smart" features inactive. However, there's a simple fix. Use smart wall switches—like those in our plugs & switches collection—to retain manual control while keeping the smart features live. That way, your bulbs stay connected to your smart system regardless of how they're turned on.
Also worth noting: opting for smart lamps and floor lighting like the stylish Satin Chrome Standing Floor Lamp gives you the flexibility of smart lighting without any rewiring hassle—perfect for rented spaces.
Smart Lighting Automation = Big Energy Wins
Smart bulbs alone won't save the planet, but combine them with smart switches, motion detection, or even geo-fencing based on your phone’s location, and you'll start seeing real results on your electricity bill. Features like timers, scheduled brightness drops, or motion-based activation can significantly reduce wastage. Consider it your lighting working smarter, not harder.
Home Hack: Use motion-sensor bulbs in hallways or bathrooms to automatically light up busy areas without running full-time lights. It's a low-effort, high-impact change—especially useful during night-time trips.
Let’s Set the Record Straight with Some Real-World Numbers
Take a look at this table below. It compares the average monthly energy usage (based on 5 hours/day usage) of different lighting types:
| Light Type | Wattage | Monthly Usage (kWh) | Estimated Monthly Cost (Rands)* |
|---|---|---|---|
| Incandescent Bulb | 60W | 9.0 | ~R28.80 |
| Standard LED Bulb | 10W | 1.5 | ~R4.80 |
| Smart LED Bulb | 10.5W (incl. standby) | 1.58 | ~R5.05 |
*Based on an average electricity rate of R3.20/kWh
As you can see, the difference between a smart LED and a standard LED bulb is minimal in cost—but the added convenience and automation potential makes the small extra watt worthwhile. And compared to traditional incandescent lighting, the savings are massive.
Conclusion
Smart lighting isn't just a flashy tech trend—it’s a practical upgrade for modern South African homes trying to stretch their energy budget. With myths busted and facts in hand, it's clear that smart bulbs offer serious value in the long term. Whether you're looking into energy-efficient LED bulbs for general use, or integrating your home with more advanced options, making the switch to smart is definitely a bright idea.

Frequently Asked Questions
Do smart bulbs save electricity compared to normal LEDs?
Yes, smart bulbs typically offer slightly better savings over time because you can control and automate their use more precisely, reducing accidental overuse or leaving lights on when not needed.
Is the standby power usage of smart bulbs expensive?
Not at all. Most smart bulbs use less than 0.6W in standby, which translates to under R2 per month. The automation features usually save more electricity overall, outweighing this minimal usage.
Will smart bulbs still work during load-shedding?
If the power is out, smart bulbs won’t operate unless you have a backup power source. Some homeowners pair smart lighting with inverters or UPS systems. Alternatively, check out our rechargeable light solutions.
