(I have just now registered here) IMPORTANT INFO: I don't know if this was posted earlier in this thread. Here are some answers for you folks who need Lumen and need to Upgrade the Light OS. Be sure to check out the following YouTube video: The video is "Hacking the Light L16 Camera Part 1" (BTW, I have not found Part 2 yet, it may not be posted). Just under the video there are also two critical links - one for downloading Lumen to a Mac and the other for downloading Lumen to a Windows PC. You need Lumen in order to get the most out of your L16.
Also, I will soon try to follow-up with more info (it's a link) on where and how to get the latest Light-OS. The latest and last version is actually LightOS-126.96.36.199-118 and I can tell you that I have successfully updated my several (yep, I have several) Light L16 cameras to this version. What I really like is that - two versions back - Beta Video was included. In this final version it is simply called Video (no Beta anymore). I am quite satisfied with my L16 cameras now. This is as good as it gets, and I am happy with what we now have. Again, I will follow-up with this additional info. I am traveling right now, but soon I will get back to all this.
So, yes, L16 owners, take heart. You can indeed upgrade your L16 cameras. Do not junk them just yet or sell them. You really can do some nice photography with them, and even get some passable video.
