Heliospectra – SIERA

The Perfect Vertical Solution.

Specifically designed for vertical farming scenarios, this light is extremely low-weight (1 kg /2.2 lbs), is water and dustproof with an IP67 rating, and has a simple mounting solution. The SIERA light bar aims to redefine the ways in which growers can approach their vertical farming installations. The highly flexible design allows for growers to set up new installations or optimize existing ones in record time.

High durability and an IP67 rating means you can easily keep these lights clean, safeguard against moisture and avoid damage in harsh growing conditions. Growers will reap the benefits of heavy duty, reliable build quality, and efficient daisy chain mounting with these incredibly light-weight fixtures. Plus, the uniquely simple T-slot mounting solution makes the SIERA a breeze to install in any facility, and as each power supply unit powers multiple SIERA lightbars, it offers safer usage and easier cable management
