Our Verdict

If weight and price are key considerations for you, then the Black Diamond Astro may be just the ticket. It's not bright for distance viewing, but has a low price and great battery life. If this doesn't make it into your pack, consider one for the glove box of your car, or your thingy drawer at home. It stands just behind the similarly priced and Best Buy winning Petzl Tikkina. The Tikkina is a much better trail finding headlamp and is brighter. The Astro has a better close proximity beam. Both offer excellent battery life, are quality lights, and sell for less than $20. For those looking for an inexpensive lamp to primarily provide close proximity flood lighting, the Astro is an ideal choice.

Cons Too weak a beam for trail finding or distance viewingExpensive, 18650 Li-ion battery is not included, heavier than averageMore expensive, heavier than average, claimed battery life is very misleadingBelow average battery life, claimed battery life is wildly misleading, single button hard to use, lame waterproofingAverage battery life, heavier and bulkier than most
Bottom Line Our favorite budget light if your needs are limited to close proximity workA stunningly bright light that offers impressive battery life. If you can afford it, it won't disappointYou can't go wrong with the Storm, high performance, quality optics, and durable designOffering excellent optics, a bright wide beam, and strong performance for the price, the Spot is one of our favoritesWe used to love the Coast, but competing lights have stepped up, while the HL7 is unchanged

Our Analysis and Test Results

The Astro is a high-quality headlamp that is reasonably priced, compact and simple-to-use, yet offers performance for close proximity work that is better than you might expect.

Trail Finding


This is not the best trail finding headlamp - it just doesn't have that much umph — and only gets a 3 of 10 score. This is the main advantage of the Best Buy winning Petzl Tikkina (5 of 10 score) as demonstrated by the side-by-side photos below.

Petzl Tikkina

However, the Tikkina works OK at distance, certainly passable, where the Astro is not a headlamp we recommended for serious nighttime hikes or any situation where a long-distance beam thow is required.


Close Proximity


Close proximity is the Astro's strongest feature. Not only did it score well with an 7 of 10, it scored better than some headlamps that cost 3 times as much. It casts a nicely diffused, wide, evenly lit beam.


Battery Life


The battery life is above average, scoring 6 of 10. It lasted 4.8 hours in high mode, which is only OK for a beam with under-par brightness like the Astro. But, low-mode output lasted 95 hours, an impressive amount (although far outdistanced by the Tikkina's >200 hours).


The Astro uses (3) AAA batteries, which are easy to replace.

Weight


At 3 ounces the Astro is light and small, typical of the lower cost lights. It is not nearly as lightweight as the Petzl e+LITE (1 ounce, 27 grams) but it also costs less, is easier to use, and offers better overall performance.


Ease of Use


The Astro is quite easy to use for basic functionality with a single button that has a nice tactile feedback. It has a nice feature of remembering its last brightness setting, so if you turn it off, it turns back on at the previous level of brightness. It also offers the ability to lock the on switch, which is neat, but we found it a bit tricky to access without referring to the manual since a long button press operates both the dimming feature and the on-switch lock.


The Astro's large single button is easy to use with gloves on.

Best Applications


This could be the ideal headlamp for you for around home and camp. It casts a soft, even light which not only makes it easy to find things, you won't be blinding your fellow campers. If your main use will be close-proximity, the Astro is an excellent choice that will serve you well. It is not the headlamp you want for following a difficult and confusing trail at night or going cross-country.

Value


The Astron is an excellent value at $20 list, and often available for less online. It was a contender for our Best Buy award. But, the Petzl Tikkina beat it out as our Best Buy winner because at the same price it offers a stronger beam, that shines nearly twice as far, and much better battery life.

Conclusion


While this is not quite the Best Buy winner, we recommend the Astro without hesitation for those who are primarily looking for excellent close proximity flood lighting at a reasonable price. It is just so compact, easy-to-use, and exceptional at close proximity applications.
