Solar LED luminaire: the even more economical alternative to LED lighting

It is not so much the unique performance it offers, but rather the need to reduce its ecological footprint and its energy bill, which motivates the switch to LED lighting. And for good reason ! Between its foolproof durability, its excellent light output, and its electrical expenditure 20 times lower than that of traditional lamps, […]

Lipo Lithium Battery

electric transport (Lipo) Heat VS (petrol): criteria for choosing a battery and comparative calculations

The performance of electric transport depends strongly on the quality of their batteries. It is currently the real Achilles heel that limits the development of electric propulsion, both in road transport, maritime and ... that air obviously. We present a quick state of the art Lithium-Polymer battery performance currently on the [...]
