Aircraft anti collision beacon. Made in Germany.
The main difference between the Rotating Beacon and the Anti Collision beacon is the physical size of the unit is shorter, and the lighting pattern is an instantaneous 360 degree strobing effect versus the ‘light bar’ rolling around the circumference of the ERB2. Both units will do effectively the same job, and both look amazing.
Eye protection is definitely recommended if you are too close to these lights. They will leave you praising Jesus, walking into stuff and seeing red spots for about 5 minutes (ask me how I know).
The main point of difference between the Thiesen Electronics products versus other manufacturers (such as Whelan or AeroLED) is the moulded plastic resin that is used to completely enclose the Thiesen lights. NOTHING will ever get onto your LED lights with this system. There is no lens to crack, no gaps to allow water or salt air in and corrode your lights. I think they compare favorably on price and you get a 3 year factory warranty.
