Coast HL8 LED Headlamp Review

The Coast HL8 LED Headlamp is one of the most popular headlamps among hikers. Its bright light, good looks and easy operation make it very attractive to many people. It comes with a rechargeable lithium ion battery which lasts up to 6 hours of use. The light is powered by two CR2032 batteries (not included).

You can charge the batteries using any USB power source such as a computer or wall adapter. The light uses a single AA battery (included) so you won’t need to carry extra batteries.

As mentioned above, the light features three brightness levels: Low, Medium and High. Each level offers different color temperature settings and a strobe mode. There are no special modes for low-light conditions like night hiking or when your eyesight is poor. The light will automatically switch between the three brightness levels according to your surroundings.

The light has a compact design and weighs just 4 ounces. It’s easily carried in your backpack or pocket. The light is made out of aluminum alloy, which makes it lightweight and durable. The light measures 1 inch wide x 3 inches long x 0.5 inch thick and weighs 2 ounces without batteries or charger.

Yes, provided that the battery is removed or the battery is able to be turned off. Leaving the battery in the lamp with the switch off may cause the battery to be accidentally turned on during transport.


How can I keep my headlamp from malfunctioning?

Headlamps have many small parts that are sensitive to impact, temperature changes, and moisture. Dropping your lamp, leaving it in your car on a hot day, or getting it wet may cause it to malfunction. If you notice anything out of the ordinary, check to make sure the battery compartment is firmly closed and dry. If any moisture has built up inside, immediately wipe it down and dry it thoroughly before using it again.

How can I tell if my headlamp needs to be cleaned?

In order for your lamp to function properly, its interior mechanisms may need to be cleaned. Dust or other small debris may hinder the proper functioning of the light. If you find that the lamp is working intermittently or having lighting problems, take a can of compressed air and spray it directly into the lens and interior mechanisms of the lamp. This will remove any dirt or debris that may be causing the problem.

Will storing my headlamp in the dark or cold affect it?

No, as long as you are sure it is completely dry internally, storing your lamp in less than ideal conditions should have no effect on it.

How can I tell when my batteries need to be changed?

The batteries will no longer hold a charge and your lamp may not turn on at all when the ON/OFF button is pressed. You may also notice a dimming of the light over time. It is important to change your batteries before they die completely as the light may begin to malfunction and can cause permanent damage.


What is my headlamp’s battery life?

On Low, the battery should last over 75 hours and over 25 hours on high. Duracell claims that their 3-volt lithium battery will last up to 10 years, but we recommend replacing them once a year regardless.

Does my lamp contain any toxic materials?

There are no harmful substances within in the casing of the lamp.

Does my lamp contain a recycling program?

Duracell, Energizer and other major battery companies have recycling programs in place where you can send in your used batteries to be recycled for free. Please see our Customer Service page for details on how to send your old batteries back to Duracell for recycling and they will send you new ones for free!

Will my headlamp work with any other battery brand?

No, the lamp is not compatible with any other brand of battery. While some of the cheaper knock-offs may fit in the battery compartment, they will not provide adequate lighting when compared to Energizer or Duracell brand batteries.

My lamp seems to be dimming after an hour on high.

Is something wrong with it?

Not at all! All headlamps have a mechanism that prevents the bulb from burning out. This is normally done by reducing the flow of current to the bulb over long periods of time. This is not a malfunction.

How exactly does the focus mechanism work?

The Focus mechanism moves a curved piece of plastic back and forth in front of the beam of light to narrow or widen the beam. Over time, friction can cause the mechanism to stick. This is easily repairable and you can learn how on our How-To page.


I heard that headlamps are bad for your skin. What does that mean?
