After seeing these little lights, I thought that it should be very handy when I didnt wat to carry something bigger. Ordered direct from LP and recieved it today. Put a fresh AAA in and it worked for about 5 minutes. Its highest setting didnt equal the medium setting on my Preon. After it quit working, I took it apart, did the usual cleaning, changed the battery just to be sure and still doesnt work. Thats when I also noticed that the lens was also cracked. I can chalk up another brand that I wont be buying again. The only plus was that the Preon head fits the LP body, so I do have the option of using it as a clicky for the Preon. At least I have that.
