PT Eos 50lm
Petzl Tikka plus (old one)
I had a PT Apex, but sold it as I didn't like the beam (horrible, guess I was unlucky there and taking it apart didn't resolve the issue. I also had an old MYO XP, which died and went to headlamp heaven.
The Eos is nice, but feels a little bulky on the forehead.
I am impressed with the little Tikkina, no messing about or high tec multiple modes, just high mode to let you walk about, low mode to read or for inside the tent. No annoying strobes or SOS!
The old Tikka Plus now resides in the glovebox of the car in case of breakdown. Interesting to note that with LED advancements the Tikkina above is brighter but has half the LED number!
The Zebralight H30 is my most used headlamp, for close work and reading it cannot be beaten by the others I own. Low for reading, mid for walking in the woods and high for anytime I want to light up a big area. Although I have noticed a very light PWM flicker on low mode, you really have to look for it but it is there.
The Silva Siju is a little gem, totally ultralight and all I take with me on mid-summer backpacking expeditions where over here in the UK we only have 4 hours of darkness in June.
My two sheckels.
