Stratum Seal

Stratum Seal is a multi-layered, sealed, watertight unit that becomes gloriously illuminated when coupled with Spanlite’s Lightbar. Lit with a bright, even panel of light from within, the outer, seen surfaces can be uniformly coloured or created to include artwork. The perfect solution for bringing artwork to life in external or wet areas.


Perfect for external signage, canopies, poolside applications and outdoor art pieces, the flexibility of its layer configuration opens it up to a wide variety of applications.

Layers may comprise of a combination of reflectors, lighting panels and front face surfaces such as acrylic, glass or stone. Layers are kept in perfect alignment, maximising light transmission. The exact quantity and position of each is entirely led by the design and intended use.

Light can be directed to come out of one or both sides, offering single and double faced illumination.

Completely watertight IP65-rated unit is robust and can weather external environments.

We can also take care of any framing requirements you may have, whether that’s producing entirely new framework or working with you to integrate with existing structures.
