Discussion: Headlamp

Hello which headlamp is better ? Lumonite Leader or Ledx Cobra? Plus and minus between this two lamps?

I believe any of the high-end lamps are perfectly fine these days, i.e. I have two versions of the old champion Lupine Betty (regular and X), when I got them they were in fact the best you could get but since then all the serious vendors have comparable versions.
BTW, last night we ran 'Retronatta', i.e. the retro night-O event where we have no age or sex classes but only divisions based on your class of lamp, going from classic Silva/Mila dual-reflector halogen via a couple of luminosity-graded backup light classes to "football pitch floodlight", i.e. the modern lights.

I agree with Terje. On the other hand I also suspect for a serious athlete neither of those would do as the only headlamp. They need also a more lightweight one for Jukola and 10mila twilight, that would also be more comfortable for casual night training runs. For example Jukola's first leg is quite often not that dark really especially first fhalf, carrying almost 1 kg light (lamp, headband, wires, battery, vest) is overkill. For some of us it might be smart to invest to the more practical "middle size" (~2000 lumen / 300g) headlamp first and get the high power one when/if it really is needed.

@Jagge: I agree! Those modern lightweight lamps are still far brighter than anything we ran with in the seventies and eighties, i.e. a year ago my wife gave me an OLIGHT for Christmas, it is both the perfect backup light for Tio/Jukola and strong enough on its own (~500 lumen) to be used for sub-hour training events. It uses micro-USB charging, and can even be used as an emergency charger for a cell phone.
Last night I used that lamp in low-power mode, in which case it last several/many (I have not actually measured it) hours.

If you find a lamp in Jagges sweet spot (~2000 lumen) it will be fine for any event, the main problem is that a 60 year old need about 3X lumens compared to a 20 year old, so the old 300 lumen halogene Silva would be more like my original 10W incandescent lamp using non-rechageable 9V batteries.
