I'm doing the happy dance.
I got my Headlamp in the mail today. It's a Silva 478 (see
here and
here). I bought it from
sailgb.com (or
extremegb.com , same company) because it was the cheapest headlamp I could find. That was before I found out the Swedish companies list their prices with 25% VAT added in, and the actual prices are lower if you're not subject to the EU-VAT tax. (Although you should verify that if you decide to order---My one order from a Swedish company was shipped using that 25% portion. I would have asked for cheaper shipping if they'd asked me.
Anyway, the headlamp was $113 with about $20 shipping (I think). I didn't buy a battery because they're outrageously priced. Instead, I bought NiMH cells (Sanyos) from a battery supplier and made the pack myself. I paid about $50 total for a 10-cell, 8000mA-hr pack. (Although right now I've got it configured as two 5-cell packs.) I did buy extra connectors from Sweden so I can make more packs and some connectors for hooking up test equipment (like a voltmeter or ammeter).
I opened the box and stuck it on my head. It was a lot lighter than I expected, and it doesn't bounce at all. I have been charging and discharging my 5-cell packs, but I hadn't actually soldered on a connector, so I went into the basement and got it ready.
I finished in about 20 minutes or so, most of which was looking for wire and a weird set of crimpers. I tried it out outside, and it was really cool. It's a lot of light.
It was a little after 10pm, and it took me about 2 seconds to decide to go for a run. I know, I know. Running on the street, in public, with one of these on is just about the geekiest thing one could ever do. I didn't put heatshrink on my pack, I just stuck it in a ziplock and used the pack from a small camelback (1L?) under my T-shirt to hold the battery.
I was really surprised by the light. It's very even, with two areas. The spot is a little wider than a sidewalk as you're running, and 2 or 3 times as long. The flood is very wide and very nice for map reading. Wearing the battery on your back is the way to go. The headlamp feels so light on your head.
I think my two bulbs are reversed. The directions say moving the switch left is low, and on mine it's high. The low beam (10 Watts) is physically lower than the high beam (20 Watts). I'll switch them sometime and see how they look the other way. I used low for 95% of the run. It was all I needed. The few times I was in a really dark spot, I put it on high. It was brighter, but I really need to try it in the woods.
I can really see why Spike loves his headlamp.
Amazingly, I ran all the way up the big hill tonight. A few weeks ago I felt like I was completely out-of-shape, and then I go to a night-O and run for most of an hour, and now this. I'm doing better than I thought I was, but I really need to get out the door a lot.
And I got a headlamp! w00t!
