SUNLITE ECLIPSE Light Deprivation Solution


Engineered for complete light deprivation, with a highly reflective, white outer skin and a black core, SUNLITE® Eclipse ensures 0% light transmission. The reflective surface maximizes available natural light from your greenhouse cover and from your artificial lighting system. Its multiwall design helps conserve energy and maintain consistent temperatures inside the structure

SUNLITE® ECLIPSE is a lightweight, easy-to-install, insulated panel that can be used in a wide range of climates. It is a durable solution for cannabis greenhouse, processing and storage areas and more.

Engineered for Side & End Walls

Light Deprivation Solution for Cannabis Cultivation

Due to the recent developments in the legalization of recreational and medical cannabis, growers are faced with several growing challenges. Commercial cultivation of cannabis requires full control over the day and night cycles. During daylight cycles, growers in the commercial market strive for maximal light transmittance and high light diffusion factors. Opaque walls are desirable for security and discretion, as well as for light deprivation control.

Palram provides a suite of solutions for cannabis growers with specific high-light transmission and diffusion panels for the roof; and opaque, reflective multiwall for greenhouse walls and gables.
