Home Solar lighting blog About solar lighting Elektra fixture: the high-performance designed for stand-alone solar streetlights

A fixture optimized to maximize solar system autonomy

Outstanding luminous efficacy up to 210 lm/W

The Elektra fixture delivers remarkable luminous performance, reaching up to 210 lm/W after optical losses, one of the highest levels in its category. As a result, in stand-alone solar systems, this efficiency has a direct impact on several key aspects:

• increased autonomy,
• better winter resilience,
• reduced energy demand for the system,
• more efficient sizing of both panel and battery.

Consequently, for a solar streetlight, high efficacy means fewer watts consumed for the same lighting level, which is a critical factor in ensuring reliable operation all year long.

Wide power range for all use cases

Furthermore, the Elektra fixture offers a wide power range to adapt to all configurations:

• 20 to 150 W,
• 4,200 to 30,000 lm,
• 3 fixture sizes: S, M, L,
• versions adapted to the UP and EverGen ranges.

Thanks to this modularity, it can meet needs ranging from cycle paths to roadway lighting, as well as parking lots, parks, pedestrian zones and rural areas.

Elektra fixture compatibility with Sunna Design solar solutions

In addition, one of Elektra’s strengths lies in its native compatibility with Sunna Design’s main solar solutions. The table below summarizes system compatibility and motion-sensor availability:

Extreme robustness for demanding environments

Stand-alone solar streetlights are often installed in harsh environments where weather conditions can vary significantly. As a result, the Elektra fixture performs particularly well in these situations thanks to its robust, long-lasting design.

Proven resistance and certifications

The Elektra fixture is certified:

• IK10 – high impact resistance,
• IP66 – excellent dust and water protection,
• C5H – 1500 h salt-spray resistance (ISO 9227),
• reliable operation from 40 °F to +131 °F  (-40 °C to +55 °C)

Thanks to these levels of robustness, the fixture ensures reliable operation:

• in coastal areas with high salinity,
• in desert climates,
• in industrial or corrosive environments,
• on remote sites with limited maintenance.

Durable materials and careful construction

The Elektra fixture combines die-cast aluminum, tempered glass and high-durability coatings to deliver excellent long-term performance, even under extreme conditions.

Responsible lighting for natural and rural areas

Stand-alone solar solutions are widely used in areas sensitive to light pollution, such as parks, nature reserves, rural areas or night-time tourist sites. In this context, the Elektra fixture is perfectly suited to protect both people and biodiversity.

Dark Sky certification

It helps to:

• reduce skyglow,
• limit intrusive light,
• minimize impact on flora and nocturnal fauna.

Adapted color temperatures

The Elektra fixture is available in several color temperatures: amber (Less than 2% blue wavelengths, ensuring it is harmless to wildlife and vegetation), 2200 K, 2700 K, 3000 K and 4000 K. Thanks to these configurations, the solar streetlight can be adapted to biodiversity regulations and to the surrounding environment.

Precision optics and cut-off options

These precision optics are ideal for controlling light levels and preventing unnecessary light pollution.

Optimized photometries: a key factor in stand-alone solar performance

The performance of a solar streetlight largely depends on precise light distribution. To address this, the Elektra fixture offers all essential photometries:

• CR / CL: pedestrian crossings
• MR (T2ME): roadways
• AWR (T4ME): wide areas
• NR (T2SH): secondary roads, paths and cycle lanes
• Specific versions available on request

Typical applications

• cycle paths
• urban and rural roads
• parking lots
• pedestrian zones
• greenways
• parks and promenades
• environmentally sensitive areas

Thanks to these photometries, the Elektra fixture maximizes the efficiency of the luminous flux, which makes it possible to reduce required power, a key advantage for stand-alone solar solutions.

Connectivity and smart capabilities

Zhaga-Ready motion sensor compatible with the EverGen range

The Elektra fixture is Zhaga-Ready, enabling integration of the Lumawise motion sensor. It provides:

• accurate motion detection,
• dynamic power modulation,
• reduced energy consumption during low-traffic periods,
• increased solar autonomy.

Elektra is thus one of the best fixtures on the market for optimizing the autonomy and performance of Sunna Design’s solar solutions.
