It arrived today. It's going to be a few days before I have all my thoughts together, though.

One question for you - did your shows up with a hex tool that let you open the light? The instructions show one, but mine does not have one. My Specialized multi-tool doesn't even have the right size hex wrench on it. I was able to get it open because I realized I have another, bigger, Crank Brothers tool that does have the right hex wrench size on it. Curious what you opened yours up with (you have to open it up to put the batteries in, so it's weird it doesn't come with a tool).

This is all the info from the bottom of mine:
K676
4xLR6/AA Bat.
BF48L20 BBL
2111

The other website another poster mentioned said this -
Philips Saferide 80 Comes with: Lamp + 4 x 2600mAh NiMH batteries + charger. Manufacturing date 4112 or later, so with better electronics, neutral white LEDs, better status LEDs and more runtime, standard mount.

So I'm not sure if 2111 is the manufacturing date on mine, and amazon is selling the older model (which is the one I have)? Since they're selling for $100 on amazon (original retail was more around $200), it wouldn't be a huge shock.
