Portable & temporary work lights
There is a large difference in use and therefore in construction between fixed lights and work lights.
Mechanical strength
Fixed lighting, mounted on poles, on walls or as a pendant light have much lower mechanical requirements to meet. These do not have to withstand drops, blows, or impacts with tools. At the same time, weight for work lighting is a much more important item.
Provision against static-electricity.
Another important difference: Portable lights have a provision to prevent the build-up of static electricity, a dangerous condition possibly leading to sparking. After all, movement against clothing, for example, can lead to this dangerous build-up. Metal housings of mobile solutions therefore have a third core in the power cable to allow the drain of static build up, plastic housings must be made of anti-static material. It is important that this property is good and lasting, even after impact or cleaning. It is doubtful that a simple layer, like can be found with polycarbonate meets this requirement. If a plastic housing with a sprayed film is chosen, we would recommend regular checking of the anti-static properties, like this tool available at Optilight France Testeur.
Our Ultra2 and Ultra3 flood lights have a house with fully thorough anti-static properties: scratching, cleaning or impacts will not deteriorate it.
Weight
There are no ATEX regulatory requirements regarding weight, possible only national requirements with regard to working conditions. The Ultra2 is equipped with a battery, which would not be out of place in a medium-sized family car with a capacity of more than 50Ah. But while the car battery is very heavy, the Ultra2 was engineered until the weight became only 5.5 kg.
