There's no LS headlamp on the way that I know of. I'm sure there will be, though, since it's such an obvious way to use a Luxeon. I would be stunned if, say, Princeton Tec wasn't working on one, but they aren't saying anything. We'll just have to wait and see.
In the meantime, you could put one in a Walmart type headlamp. The Rayovac "kids" headlamp is good, and there's a 3 AAA headlamp that they sell for around $18 that will take one (with resistor), and also has 3 LEDs and dual switch.
I'm currently working on putting one in a 3 AAA headlamp I got from ****'s Sporting Goods for $25, which I think is a little better quality. In fact, I'm charging NiMHs as we speak for some current draw and heat generation tests. It also has 3 modes: 1 red LED, 2 white LEDs, and the main lamp. I find these multiple colors and brightness levels to be VERY useful.
