For the past two years, my two main headlamps for hiking and camping have been the Petzl Tikka 2 and the Black Diamond Spot. I like both of them; although I also intend to do a gear review about the Tikka, and also of a new Energizer headlamp I acquired just the other week; this review would deal with the Spot.
See the PinoyMountaineer Gear Review for Petzl headlamps
I purchased my Black Diamond Spot headlamp in the famous street of outdoor shops in Zhongshan Road North, Taipei, where it was sold for just 1300 NTD (less than 2000 pesos). Since then, this headlamp has seen action in Mt. Kilimanjaro and Holy Ridge in Taiwan - both of which are six-day treks.
The Black Diamond Spot is a good standard headlamp for hiking; it has higher luminescence than its Petzl counterparts, such as the Petzl Tikka, Tikka 2, and even the Tikka XP. In fact, the newer models of the Spot just upgraded from 75-80 to 90 lumens, making them even more powerful. Better still, the power / function button acts as a 'dimmer switch' and you can actually go as low as 5 lumens. You can adjust the brightness depending on the situation!
Moreover, it has a red light option, unlike the Tikka (the Tikka XP, however, has red light modes).The red light is preferred by many for night vision. As the REI website explains: "Red light does not cause our pupils of our eyes to shrink the way white light can, so it's nice to use when viewing the night sky."
There are higher-level models, such as the Black Diamond Storm, which has more lumens (100 vs. 45-6) an the Black Diamond Icon, which has a bigger battery pack, but I don't think these are necessary for hiking purposes; actually, even a 45 lumen-headlamp would suffice and the Spot is already on the 'brighter' side of the spectrum. It compares favorably with the Petzl Tikka 2; and its edge lies on its two bonus features and more luminescence that I have mentioned.
Having said thus, I highly recommend the Black Diamond Spot as a standard hiking headlamp.
