The Rabbit Hole
Ultimate load-shedding lightbulb battle — with one clear winner

MyBroadband tested several load-shedding lightbulbs in South Africa to see which offered the best battery life and brightness.

Rechargeable lightbulbs provide a cost-effective way to have light around the house during power outages without using a larger backup system.
 
Ive got the Eurolux and Litemate ones and the Eurolux one's weren't terrible.

Will try out the Magneto ones, looking for some that last for thr 4 hour slots.

Also, these bulbs have a quick degrade profile, and at higher stages aren't able to quickly recharge.
 
Had the Eurolux ones. They were very dim when the power went out and only lasted about 6 months to a year

Agree they do degrade quicker because of the heat when being used on normal power. Repaired a lot and some you can clearly see the plastic turned yellowish not white anymore.
 
Normal LED lights produce 75-100 lumens per watt. The numbers in the article indicate that brightness on battery power is significantly lower than on mains AC. The article kinda glosses over this point...

The battery capacities are listed in mAh, but the voltage is not stated, making it hard to calculate the stored energy. Edit: The Eurolux datasheet says 3.7V. So that makes 3.7X1.2 = 4.5Wh. Not a lot of power...

I have the LEDVance, they also come with variable brightness settings (3 levels) that might also boost or decrease battery life. Also, this bulbs are ****ing bright when running from electricity.

So they are 'emergency' backups, not a full substitute for the original lights.

Yes and no. You can only set the brightness when it is screwed into that fitting with the button that comes with it. You can use it as a permanent light bulb, but for me it is too bright for that.
 
Pity the Gizzu light wasn't included. When I bought it it was a toss up between the Gizzu and the Magneto, but the the Gizzu won because it warm white was available when not load shedding. It also charges in four hours.

Good to see Magneto come out tops here. They are a well built, reliable and affordable brand :thumbsup:

No man, please use the Spoiler feature to name the #1 winner otherwise people are not going to read the article. Thank You

Yeh but the magneto wins because it's the dimmest of the lot on battery.

...the article quietly ignored a significant bit of info... brightness on battery.

We have two of these Aurora (as seen in the link) lights, and compared to the others we have, they stay on the longest (>6hours) and also keep their brightness the longest. Excellent build quality.

Correct, assume lithium cells at 3.7V x mah to get watt hours stored.

Clearly they derate their power output dramatically when on battery to achieve the run time.
