Hoping to appeal to some folks with more experience and expertise on these things.
I recently purchased a Taz 1500. After using SECAs in years past and seeing the beam pattern of my girlfriend's Urban 700, I knew that I wanted a L&M for night/snow riding this year.
The box arrived, and I opened it with the greatest of anticipation. The light is beautiful, compact, and everything I had hoped...until I turned it on. On high, it sends a glorious, crushingly bright rectangular beam pattern out. On medium, low, pulse, it also sends out a loud, super-high pitched sound that gave me a headache for about an hour. I charged it up, and let it run a little bit with the same result. I thought, "you're just being sensitive." So, I took it outside hoping that it wouldn't be so noticeable there. But it was.
I contacted the ebay seller, who very graciously offered to take it back under warranty. So, I sent the light back.
Today, I received a message from her that the L&M rep had actually stopped by their shop, inspected the light, and stated that this was normal. She also said that several SECA's, a Taz 1200, and even some Lezyne's made similar sounds and that this is inherent to high powered LEDs.
I have owned a Magicshine 1000, held an operating taz 1200 in my hands, and used SECAs for several night races. I also have a nightrider lumina 700, and I have used my gf's urban 700. I have never heard anything like this before.
At this point, I am attributing the difference in experiences here to variations in high frequency hearing. And I do not believe that this sound is inherent to high powered LED's, mainly because the sound is louder when the light is stepping down the output and is not present when it is on high.
So, any opinions or help out there? Any Taz 1200 or 1500 owners care to chime in on this? Do your lights make a headache-inducing high pitched sound?
