Solar power highlights Sernis' new road studs

SR-i19 and SR-i25 developed for road delineation, including bends and crosswalks

SR-i19 solar stud: visible up to 1km away

Sernis has launched two solar road studs: SR-i19 and SR-i25.

They use microcontroller technology, and only rise 9mm and 10mm respectively from the road surface: the company says they are "ideal for road delineation, bends/curves, and crosswalks among other applications".

They have constant brightness during all functioning periods and can be seen up to 1km away.

SR-i19 has a high light output due to its 3 LEDs for each side, with an aluminum base giving it strong mechanical resistance.

SR-i25 has a stainless-steel cap that makes it ready for snowploughs, while built-in GPS technology allows flashing synchronisation. It is also available in aluminum.

Sernis highlights its high-performance photovoltaic solar module, with silicone-free junction sealing technology allowing better, faster, and cleaner maintenance.

The technology applied to both models "increases the performance of solar power studs with energy storage by battery or capacitors and protects the road stud against the deep discharge of the batteries/capacitors", Sernis insists. 

'Sleep' mode prevents discharge during storage or transport, and the manufacturer points to their ease of installation and the fact that the studs require "virtually no maintenance".

    Adrian Greeman looks at developments in software visualisation packages. The capacity to make visualisations has been growing in importance over the last decade, and is now a well-accepted part of consultations and client presentations. But making high-quality images of projects is still a major undertaking and larger consultancies employ specialist departments to do so. Costs are coming down but it can still take a while, and some high-capacity hardware, to produce realistic renderings from drawings and 3D
