I bought a new Fenix L2D from Amazon.com a short time ago. It worked fine out of the box when I tested it. I used it on my commute (as a helmet light) for the first time last week. My commute is 40 minutes or so one way, and the temperature that morning was just above freezing, so the light should have been well cooled. It was set at steady light, medium brightness.
I arrived at my coffee stand and turned off the light so as not to blind the barista. After getting my coffee, the L2D would not turn on again. Completely dead. About an hour later, at work, I tried the light again and it turned on, but would only operate in four of the six modes it's supposed to have (the three steadies--low, medium, and high, and the SOS flashing mode). I was using Sony NimH rechargeable batteries, which were fully charged when I started my ride.
Went home that day and switched the rechargeables for Costco Kirkland AA batteries. Used the bike the next day, and the same thing happened--light won't turn on again after it's been turned off--only four of six modes working. I pulled the Kirkland AAs out of the light and one of them was leaking. The batteries were brand new when I put them in!
Also, when I've turned the bezel to switch between 'general' and 'turbo' modes on the light, per the instructions, the only thing that happens is that the light goes from on to off; there is no change in brightness.
I've sent the Fenix back to Amazon for an exchange, but I'm wondering if I chose the wrong light. I'm not impressed with the L2D so far.
Has anyone else experienced similar problems with the Fenix L2D? Is this an anomaly or is this a flashlight I'm going to have to baby, make sure it doesn't get too hot, check the batteries every day, etc., and even then not be sure it will work when I need it?
