R&D in solar warning lights emphasizes longer service life

Makers are utilizing high-power LEDs and batteries in new releases.

TOP TRENDS

  • Upgraded light source: Recent China-made solar warning lights come with LEDs that can function for at least 50,000hr. Some diodes can even go beyond 100,000hr. These have luminous efficacy at 80 lm/W and can be seen from about 800m. 
  • New raw materials: For the housing, makers adopt acrylic in most releases because of its durability. Its service life can exceed three years even under harsh weather conditions. Metal such as aluminum is employed as well.

Enhanced batteries: Several units have integrated NiMH, NiCd or Li-polymer batteries that can last at least 12hr after a full day of solar charging. A few can function for about 3 nights.
