Temporary Site Lighting (TSL) – still operating after 5 months 1.5m underwater

Today (14 April 2015), we pulled a “TSL” lighting production unit from our test tank for a visual inspection – The look might be appalling…

The good news however – TSL is still in perfect working condition, watertight and electrically safe.


Jackson Electrical rigorously tests all products prior to market, and continues to develop and test these products over their lifetime based on comments from industry and customer feedback.

In this case, a test rig cycles power on the unit periodically. An interesting issue with waterproof lighting is the fluctuating temperature – and subsequently the fluctuating pressure which in turn makes any waterproof light fitting a pump, trying to fill itself with water. The rig also periodically electrically tests and logs the state of resistance, bulb condition and so on. You can see in the unit shown above the base is molded in clear plastic to enable a visual check of the fitting base without disassembling.

We are pleased to find no issue in this longer term test. The units had been tested underwater for 100+ hours prior to being marketed – however there is no replacement for many punishing hours in the worst case scenario to prove to customers that the product is robust.



Lastly, the supposedly temporary (!) test rig. This was built for ‘test-to-failure’ of the TSL product. However it just wont happen. It is looking more and more like we are stuck with this eyesore forever…



The world famous Karaka Sales complex is situated just 30 minutes from Auckland City and is home to the New Zealand Bloodstock Sales. Jackson Electrical has had a long association with this event by supplying temporary power solutions for the entire two week long duration of the event. From powering broadcasting units to supplying power for the horse floats and camper vans, we have always designed a layout to suit their requirements.

Rhythm and Alps

Rhythm and Alps is the annual New Year’s Music Festival located in the beautiful Cardrona Valley in central Otago.

The challenge: Jackson Electrical was asked to supply an outdoor water proof lighting solution for the 500 meters plus of camping and walkways on the R&A Site.

The solution: 25 lengths of the Jackson Electrical manufactured chain lights which were hired for a four day period. Designed for both indoor and outdoor applications, with a protective polycarbonate lens for the low energy lamps the Chain Light ticked all the boxes.

The outcome: R & A were highly impressed with the lights, and subsequently purchased them for use at future events.
