LED h2 emergency headlamps’ sales trends are continuing increase. in order to protect earth, save energy, improve efficiency, many scientists try to use innovative energy technologies, such as the solar technology’s application.



Unlike most rechargeable LED headlamps, this one uses lithium-ion batteries that can hold their charge for a year - making this an option for disaster preparation and household power outages as well as for hiking. For even more uses, you can set the LED solar headlamp to a photocell mode that automatically turns the light on at dusk and off at dawn. Since you never need to replace batteries, this headlamp is also an option for travel. The main drawback is the lack of red light for night vision, but the manufacturer tells us this is a feature they plan to add.


The EL8 Solar Headlamp is getting well-deserved attention right now. This innovative solar headlamp uses a 5-LED array to provide a wide beam in several modes, including a strobe light for alerting rescuers. Testers say the brightest setting provides enough light for night hiking, while the low setting is fine for campsite tasks.


The 3-ounce headlamp is powered by a small external 3-ounce solar panel that can be attached to a backpack or jacket. Both headlamp and solar panel are water-resistant. Charging the solar panel in full sun for eight to ten hours provides 12 hours of bright light, then 12 to 18 more hours at a dimmer level. A battery meter tells how much charge is available. The solar panel also charges the headlamp even under tree cover or on an overcast day, but takes twice as long to do so.

Besides, the LED emergency h2 headlamp is also a good choice for you. You can use this headlamp on a clip as well as its elastic headband. The beam is wide to illuminate tasks very well, but can project usable light as far as 60 feet. Maximum output is 21 lumens (or 23 lux at two meters), so it's not as bright as some headlamps. But its main drawback is relatively short battery life - 35 hours at its high setting, 45 on low.
