Orienteering (Night) 30:00 [3]
Near home map. Getting used to new lamp. RG
Some comments about the lamp:
Lamp was quite nice. I had some difficulties in a very dense bush because the light was so bright. I guess I need some practise to get used to the brightness. Also course/terrain was a bit too urban (Helsinki central park) to tell much about what it is to run in deep forest with this light.
The head band loosened during the run, and I had to stop once to tighten it. The band and the material isn't as good as it should. I think may havet to get better head band.
I kept the batter in he back pocket of my running tights and it worked well.
I think I'll try again tonight.

Note
OK, HID is history, now I am a happy led head lamp user. Anyone want to see / know more?

Note
I'll put some lamp photos here. This is the frst one. Our head lamp arsenal. Can you pick the new one?
Now I noticed the carpet is yellow. This also is the last day for Bubo's photo contest and this is the only photo I have, so I must try my luck with this one.
The new lamp: photo 1 and photo 2
Led with 15W power vs halogen 20 W (Mica)
Led 9W vs halogen 20 W (Mica)
Led 1W vs halogen 20 W (Mica)
Led 15W vs halogen 20 W (Mica with nimh battery) vs halogen 20W
(my stone age Silva with nicd battery)
I don't have comparison photos of the broken Mila HID, but I am quite sure this led is a brighter that the Mila hid. They claimed Mila had about 950 lumens and this led should have only 830, but I guess Mila must have been closer to 700 lumen. Or at least this led look's a lot brihter.
The led look very impressive in real life. Minna did dome test loops two days ago, and when she came back it looked like there was some forestry machine/trackor working or a trainn coming, it so bright and white it doesn't look like O head lamp light at all.
I also compared this with one year old Lupine Edison X, and this led was far brighter. It seems like Lupine HID lights are used to dim quite fast, so you need to change the bulb/reflector pretty often if you use to lamp if you like to have bright light - and the bulb is pretty expensive. I believe led is the way to go at from now on. You even can drive it with different wattage to ge the light you need and as far as you need.
EDIT:
If you wonder: Li-ion battery weights about 200 g and it should give over 2.5 hours light with 15W power. I will keep it in the pack pocket of my running tights, so no battery vest needed.

Orienteering 15:00 [1]
Head lamp testing, compared a tiny led lamp against my old 20W halogen. Too sick to run, just walked and jogged about 15 min. Minna ran the actual test course.
The new Mila HID got broken and I need to find a replacement. The led light we tested is one alternative, it's so tiny and light you don't need any battery vest with this.
