The Coast HL7 has a lot of good things to offer, a strong beam that shines for 112 meters, very good flood lighting, and it is an easy to use product. It remains a strong competitor, but it no longer makes it into the top three scoring lights in our test. Lights such as the Black Diamond Storm and Spot offer better performance a similar or lower price. Our issue with it today is mostly that it is largely unchanged, while the competition has been improving lights much more significantly each year.

|Pros||Excellent brightness and beam control, often available online at discount||Bright wide beam, good battery life, durable design, rechargeable||Excellent trail finding and close proximity beam, waterproof, above average battery life||Excellent spot light capability, wide evenly lit flood beam, above average in most ways||Bright, wide spotlight, clear/smooth optics, long battery life, robust design|
|Cons||Average battery life, heavier and bulkier than most||Expensive, 18650 Li-ion battery is not included, heavier than average||More expensive, heavier than average, claimed battery life is very misleading||Below average battery life, claimed battery life is wildly misleading, single button hard to use, lame waterproofing||Heavy, bulky, and expensive|
|Bottom Line||Previously one of our favorites, but hasn't kept pace with competitor's innovations||An impressive, powerful light in a small package that won't disappoint if you can get past the price||A durable light that will last for years with a bright high-quality beam, slightly higher in cost and weight||A quality, durable, and bright light that hits the sweet spot for most people's needs, despite dubious marketing claims||A quality light with strong battery life, but no longer our top pick for epics|

Our Analysis and Test Results
The Coast HL7 has been around since 2012, and has had a few upgrades in performance since its original introduction. The design remains largely unchanged, even though it is today brighter than the version we first tested. Unfortunately, competing headlamps have changed a lot in that time, and so while the HL7 remains a very good product, we no longer recommend it over competing lights, in particular, the Black Diamond Storm and Spot offer better performance today, at either about the same price, or even lower cost.
The HL7 offers an excellent trail finding beam in its spot mode, shining 112 meters, and with very good optics. The beam is a bit hot in the center, not as even and wide as top competitors like the BD Storm.
The HL7 also offers very good flood lighting, which is easy and intuitive to get to by rotating the front lens to zoom in or out. Lighting is wide and fairly even, above average.
We find the Coast to be easy to use, and intuitive. With a single button to turn it on in the front, a zoom dial on the lens, and a lever on the rear battery pack to change brightness. Each function is obvious, and simple.
The Coast is a bit heavy at 4.5 oz or 127g, and the two part package, with the battery in the back and light element in the front is somewhat bulky.
Battery life is OK, but only about average, with 3.1 hours run-time in high mode, and 23 hours in our low mode test (using a similar brightness level to competing lights best mode for close proximity use).
The Coast is a quality product, that offers compelling performance. It ranks in the top 5 in our review on overall performance, which is impressive in a field of more than 20 top headlamps. And, typically found at a reasonable street price around $35 online. Our issue with the Coast today is not so much with it, but simply that competing lights, selling for about the same price, offer a better value. The BD Storm outperforms the HL7 in every category except ease of use, and sells for about the same street price. The BD Spot bests the HL7 overall, yet can typically be found at a lower street price online.
