Many available renewable sources are hardly harnessed due to high conversion cost and sophisticated technical need. Solar is one of the reliable renewable resource and it is environment friendly

20/1/2020 · 2.High Efficient Solar Panel:Adopted monocrystalline silicon solar cells, the conversion rate reaches up to 20.5%. It has 15% electricity more than other products in the same solar light time, Made with high impact ABS lamp body that has high-temperature resistance, anti-corrosion and waterproof too,which ensures longer usage time.

OiSCAPE is a manufacturer of solar & led lighting, we supplying products with the latest in solar integration, energy storage, and led lighting distribution, always provide high-quality and cost-effective solar illumination for outdoor applications. Our breakthrough

High-quality LED tunnel lights can function for up to 100,000 hours. Some of the LED lights used in tunnels have a beam angle with a horizontal axis of 100° and a vertical axis of 90°. The luminaires distribute light using a beam pattern and the input voltage is 100-277V AC.

Smoothing out the luminance transition from high to low resulted in responses of greater visual comfort, even though glare metrics do not take this into account. Traditionally, the outdoor luminaire’s “glare” angles have been 75° to 90° from nadir.

Costs for pedestrian and bicycle safety infrastructure often vary greatly from city to city and state to state. This document (and associated database) is intended to provide meaningful estimates of infrastructure costs by collecting up-to-date cost information for

【High-efficient Solar Panel】: This solar led outdoor lights works automatically without electricity as the solar panel absorbs the sun rays and generates power for the light. Our hikeren solar security lights panel of polycrystalline silicon converts up to 20% of the sunlight into electricity energy which ensure long lasting standby time.

pedestrian areas is currently dominated by metal halide (MH) and high-pressure sodium (HPS) sources. quality, optical design, thermal management, and cost. Current LED product quality can vary significantly among manufacturers, so due diligence is ...
