At the risk of hijacking Davide's thread . . . honestly I would not bother with an older 8 AA model for a focus light. I got a similar light long ago, also huge and heavy. Then I replaced it with one of these from Big Blue that uses only 3 AAA and weighs nothing but puts out higher quality light even if rated the same output. The LEDs are so much better now, and cheaper. Big Blue also has a few models that can be focused from wide angle to narrow spot.
Now I use a model from iTorch that also has genuine red light, like Sola, and like it so much better. The ability to power down to lower intensity is really useful, especially at night.
Anyway, there's a separate thread for focus lights so perhaps we should move over there:
