Black Diamond Cosmo Vs Petzl Tikka – Best Headlamp for Backpacking?

A good headlamp can be a backpacker’s greatest ally in the wilderness. Stashed in the bottom of a daypack, it will come to the rescue when the sun sinks below the horizon sooner than expected. Many backpackers enjoy hiking late into the night with the help of a high lumen headlamp.

At first glance, it might be tough to tell the difference between a $20 headlamp and a $50 headlamp. Some headlamps can cost as high as $200 – but pack way more of a punch than most backpackers require.

In our research, the Black Diamond Cosmo headlamp has the best cross-section of price and functionality for backpacking, but when Petzl released a newly redesigned Tikka headlamp in 2017, they decided to give the Cosmo a run for it’s money.

Black Diamond Cosmo

Lumens 200
Weight 89 grams
Max Battery life 180 hours
Waterproof IPX8
Max Range 70m
Best Feature Dimming

At $29.95, the Cosmo blasts an impressive 200 lumens with 45 hours of battery life at the highest setting.

Our favorite feature was the ability to dim or brighten the beam to our desired setting – instead of being stuck with the standard high, medium, and low.

Only weighing 86 grams, the Cosmo great for hiking and backpacking, and easy to stash in your daypack and forget about until the sun starts to set.

The 180 hour battery life continued to impress us as we took it on longer late night hikes.

Petzl Tikka

Lumens 200
Weight 89 grams
Max Battery life 240 hours
Waterproof IPX4
Max Range 60m
Best Feature Rechargeable Battery

After getting a redesign, the Petzl Tikka quickly caught up the Black Diamond line of headlamps, now offering 200 lumens at the same price point and weight.

While not as waterproof as the Cosmo, the battery life is 60 hours at the highest setting and soars to 240 at the lowest. A

major downside is that the maximum range of the Tikka is 10 meters less than the Cosmo.

Our favorite feature is the ability to use a rechargeable battery, reducing overall waste.
