l 3 high power CREE LED, make sure LED keep bright while use

l Power supply in DC(48V)& AC(110-240VAC), the light could work normally when input 48VDC/110VAC/240VAC

l LED power supply board includes short circuit and open circuit protection, Line surge protection by metal oxide varistor


l Bird deterrent spike on top

l Unique designed PMMA lens for converging light and good transparency

l High translucency and anti-UV polycarbonate cover could use 3-5years without yellowing

l UV protection Powder coated bright yellow color base make better visibility and also long life in harsh environments

l Base material is die casting aluminum which has strong corrosion resistance, Shock and Vibrations protection

l 3/4inch thread hole make pole installation easy

l No screw fix type - just twist, the cover will be fixed tightly

System design

l Built-in photocell for day/night operation(dusk to dawn operation, automatically turn on when background luminance is below 50cd/m2

l Steady(factory setting)/20FPM/30FPM/60FPM DIP switches on PCB

l Surge and lightning protection


l Alarm contact(NO COM NC)for remote monitoring

l Infrared LED for pilot using NVG

l GPS sync flashing
