Grid Shift Predator Solar Streetlight
The Grid Shift Predator solar streetlight is a high-performance, low-profile lighting solution engineered for durability, efficiency, and long-term reliability in demanding environments. Featuring an integral monocrystalline silicon solar panel with up to a 30% conversion rate, the fixture delivers exceptional output of up to 177 lm/W while fully recharging in as little as eight hours. A built-in photocell sensor ensures automatic dusk-to-dawn operation, while the deep-cycle battery is designed for more than 2,000 charge and discharge cycles over a 25-year lifespan. Constructed with marine-grade aluminum and stainless steel and finished with a UV-stabilized polyester powder coat, the Predator offers superior corrosion resistance and longevity. Its streamlined design reduces wind resistance, and all key components are housed beneath the solar panel for enhanced protection and easy maintenance. Available in 3000K–6500K CCT options, including a wildlife- and turtle-friendly amber CCT, the Grid Shift Predator is a versatile, environmentally responsible choice for modern solar site and roadway lighting applications.

City of San Bruno Solar Streetlight Conversion
The city of San Bruno is located 12 miles south of San Francisco, on the San Francisco peninsula. Fog and low overcast are common in the summer months but that didn’t stop the city from deciding to convert its troublesome unreliable, and obsolete regulated output (RO) street lighting system to solar-powered streetlights.
The city began the process to explore solar options in 2023 and after an exhaustive evaluation selected GridShift, represented by GBL Infrastructure Solutions. The GBL team, and GridShift application engineers, worked closely with city staff to understand its climate, neighborhood site conditions, lighting criteria and overall goals and objectives. GBL and its partner GridShift, provided the client the conceptual design, photometric design, product specification details, and structural engineering services. To ensure success and address the challenging climate, GridShift modified its popular Predator series product to maximize solar exposure and battery run times. GBL’s project management team coordinated the overall project which included documentation management, quote and order placement, shipment, delivery, installation support and commissioning.
Phase 1 of the conversion is now complete, and citizens are once again experiencing
well lit, safe streets.

Capitola Wharf
Capitola is a small seaside town in Santa Cruz County, located on the northern shores of Monterey Bay. The city is a popular tourist destination with vibrant shops and restaurants and a centrally located beach. Capitola was named a best California beach town by “USA Today” and is also recognized as the inspiration for the film “The Birds”; in the summer of 1961 hundreds of birds attacked the town, thus inspiring Alfred Hitchcock, a nearby resident, to direct the film.
A key infrastructure feature of Capitola is the wharf which dates back to the 1850s, originally serving as an outlet for the produce and lumber grown in the interior. The wharf sustained significant damage from severe winter storms in January 2023, including a section being torn in half by powerful waves. The community of Capitola organized, and the wharf underwent a year-long $8 million reconstruction, reopening in September 2024.
GBL worked with local firms Triad Electric and Fuse Architects, along with city staff, to help with the re-lighting portion of the project.
GBL looks forward to continuing to work with the city on the eventual development of the “Head of Wharf” master plan.
Gunner Ranch Trail Solar Lighting Project
GBL collaborates with Madera County’s Valley Children’s Hospital on Gunner Ranch Trail solar lighting project.
Situated atop the San Joaquin River bluffs and surrounding Valley Children’s Hospital (VCH), Gunner Ranch West is a development project in Madera County, California, encompassing residential units, commercial property, hospital-related services, and recreational spaces including the Gunner Ranch Trail. The parks, trails, and open space components connect into a cohesive community, providing ample passive and active recreational opportunities as well as access to the San Joaquin River Parkway. The final element in the project recently completed was to expand the use of these “wellness path” trails into the evenings through the integration of solar lighting. VCH and the County of Madera design team at Westwood Professional Services worked with GBL and its manufacturing partner Grid Shift, to develop a solar lighting solution that would provide ample, uniform lighting along the paths. The Grid Shift “Siege” All In One (AIO) system was selected for its robust design, proven performance and reliable lumen maintenance, assured by Grid Shift’s Burn Time Testing™. To provide incremental power to a small weather station on the site, Grid Shift also designed a unique ‘power station’ pole which consisted of the conventional Siege solar lighting luminaire and a supplemental panel/battery pole-mounted assembly to generate the power for the weather station. To reduce the cost of the system, motion sensors were incorporated into luminaires. GBL and Grid Shift provided the client the conceptual design, photometric design, product selection and specification details, and the structural engineering. GBL’s project management team coordinated the overall project which included documentation management, quote and order placement, shipment, delivery, installation support and commissioning. The project was recently completed to the delight of the area’s residents and visitors.

South Lake Tahoe ‘Dark Sky’ 2200K Lighting Upgrade
GBL collaborated with the city and its various agency partners in re-lighting bicycle paths along U.S. Highway 50. U.S. Highway 50 is a prominent gateway road to the region’s alpine skiing and entertainment venues. The city owns, operates, and maintains approximately 700 pedestrian light fixtures and approximately 200 metal halide pedestrian light fixtures along roadways, walkways, parks, and trail networks. According to the city, Phase One of the project was completed in 2023 which included the conversion of aging first generation 5000K LED luminaires pedestrian lights to more energy efficient, ‘dark sky’ friendly 2200K light fixtures. The application of 2200K light sources, a warmer color of light, is believed to be one of the largest decorative conversions in the state. GBL’s partner, Lumecon, a lighting manufacturer based in Farmington, Michigan (Detroit) developed the 2200K retrofit “engine” to meet the city’s photometric, installation, and reliability specifications. The Lumecon kit improves the luminaire’s ‘cut off’- the directing of all its light to the ground-and provides improved uniformity to enhance visibility. Phase Two* is for additional sections of Highway 50 and includes completely new Lumecon 2200K decorative luminaires and specially designed steel poles from GBL’s partner Valmont, based in Valley Nebraska (Omaha). Steel poles are often used in place of concrete poles due to their light weight, availability, and reliability. To ensure long life in the harsh Sierra climate, the steel poles will be finished with Valmont’s proprietary “V-Pro” finish. Valmont’s V-Pro Protection Systems were developed utilizing comprehensive testing and are evaluated under numerous environmental conditions by an independent laboratory.
