Do you have information on how long will the new regulated (constant output level) models operate on various intensities, please? I like the hybrid battery option very much, but did not find any relevant information on the performance.
I tried emailing a Petzl representative in my country (Czech republic), but she did not know. I stated my surprise with Petzl not providing this information as they did with previous models. The representative said the reason is that stating correct numbers actually made Petzl models seem worse that their competition. I agree with this as most other brands I looked at -Len Lenser (named Coast in the US), Fenix, Black Diamond - just state the maximum luminosity a maximum running time (until the light drops to something unusable like 5 lumens). It is difficult to find out whether their models are regulated and how long they last before they drop too much. This information is important to me since I'm looking for a headlamp for night trail running and need to make sure I have sufficient light for the whole event.
Now I own Petzl Tikka+ and I'm happy with it. Unfortunatelly, on 110 lm it lasts only 2 hours, so I was looking for a headlamp, that would last longer.
Would the Aktic Core be compatible with the Tikka Adapt Kit to put it on my helmet? I have a Tikka XP attached to my helmet with the Adapt Kit.
If yes, I would maybe consider bying the Aktic Core.
Fantastic news about the E-lite hitting 50 lumens. That might explain why they had them on sale so that I bought 4 of them a bit ago:-( LOL
Crap, the new one has a whistle on the headband, still runs off the 2 coin cells, comes with a case and they are still claiming 26 grams. For $29 I'm breaking out the credit card right now.
Interesting, says "SKU not available". (SKU: E02 P4). I'll try later. Oh yes.... she will be mine.
The specs tells me it should burn 60h on 300 lumen. That is very long in comparison with HL60R that has 3h runtime on 400 lumen on paper with 1x 18650.
There's no LED so efficient that it will burn for 60h at 300 lumens with such a small Li-ion or Lipo battery The battery doesn't hold that much energy. That spec has to be an unregulated mode starting at a quoted 300 lumens and then fading. To really get a full 300 lumens for 60 hours with the most efficient electronics and LEDs, I think you would need about 15 to 18 x 18650s (more or less).
