I am trying to learn about par 36 led landing lights for my experimental aircraft. I am currently using 100 watt halogen lights. I would like a useful light output although I seldom fly at night. I like the wig wag feature to increase people’s ability to see my aircraft during the day. The light output seems to vary widely as does the price. How many lumens do I need? I purchased some led spot lights at an auto parts store and light output was mediocre and they didn’t last long. Please help me to make an intelligent purchase this time. Thank you.
