When brand new. I'd love to see how bright they are after about 10 years in service (LED's do lose considerable brightness over their lifetimes...).
This is true of strobes as well. They slowly get dim until they burn out completely. I work for an ambulance and one of our trucks has a combination of LED
's and strobes. The LED
's are gen 1 as the truck is from 2003 however they are still extremely bright. We recently had to replace one of the strobe units on the rear, and the new one is much brighter than the old one, however the LED
's which are the original from 2003 are just as bright as the new strobe.
Whelen which makes aircraft lighting products along with emergency vehicle lighting systems has been using LED
's for over 10 years. The newest systems are extremely bright and use much less energy than strobes. The only think I dont like about the new LED
aircraft lights is the flash pattern. Instead of having a rapid on and off flash like the strobes, they stay on for a second before turning off, making more of a blinking pattern than a quick strobe like pattern. I dont think it as as eye catching and I'm curious to know of any other pilots have noticed this.
