There is absolutely nothing wrong with your evaluation of three landing lights available to general aviation aircraft. (See March 2009 Aviation Consumer.) I think it will be extremely useful to many aircraft owners who have to wonder what the best option for landing lights really is. However, I am writing because I believe that my company, Laminar Flow Systems Inc., has available a Final-Light LED landing light which would have produced quite a different result, if it could have been included in the tests. I am not faulting Aviation Consumer for not including it—the Final-Light is only just now becoming available, although I showed it a Oshkosh a year ago. It comes with an FAA DER approved 8110-3 form included in the $350 to $400 price. Since there is no immediate prospect of a new test happening, I have made a video of a similar test, which included our Final-Light as well as the ones AC tested, and some other combinations. You can see the video at You can also find it on YouTube by searching "LED Landing Light Test." I cannot pretend to the impartiality of the Aviation Consumer tests, but I will state that all the lights were tested under the same conditions. I will also be sending Aviation Consumer a Final Light in the hope that you will get a chance to evaluate it soon.
