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…
