Lighting Battery Backups

If you are looking for a better backup lighting solution due to the sustained and longer load shedding periods then you need to consider our standalone inverter and battery kits!


Why Are They Better than Rechargeable Bulbs?

Rechargeable bulbs are great however they do require the light to be on in order to charge so if you forget to turn it on during those times you do have power then the light does not charge literally leaving you in the dark during load shedding.

The back-up systems require a wiring change and an additional Live wire to be installed and connected to the battery system - what happens then is that the batteries charge the moment power is restored. You don't have to remember to turn the lights on in order to charge your standard bulbs.

This system also allows you to keep your current lighting in place - no new bulbs - you just install the battery system correctly and away you go

The Down Side?

Cost - these units are made up from high quality batteries and an inverter so the costs can be higher than just installing a the standard rechargeable bulbs.

However a single kit can run multiple lights for long periods of time if sized correctly.

These units will also require an electrician to install them as they will need an additional live wire to be installed and connected on the circuit in most cases.


The units come in 40, 85, 100 and 150 Watt packages so how does one size the correct unit for you?

The labelled wattage (40, 85, 100 and 150 Watt) will run that wattage load in for an hour. So for example if you have a 40 Watt system but only 20 Watts of lighting you should get close to 2 hours and similarly 10 Watts of lighting on a 40W system will give you 4 hours approximately.

These numbers are a general guideline based off a fully charged battery. This will also degrade over time as the battery ages and is used which is quite a bit given our current Eskom situation.

The basic math is Kit Size / Lighting Loading = Run Hours

This is the basic run down of this alternative solution to your lighting issues during load shedding and if you are interested in this option then please contact us and we can guide you correctly based on your requirements.
