The Elwis Pro H4-R is a focusable and rechargeable LED head torch that offers a maximum output of 410 lumens from a 5 W Cree XPG2-S2 LED.
This light has the ability to be focused from a spot to flood beam, giving the user the flexibility to select the best focus for the task at hand. The wide beam profile provides a 1.2 metre diameter circle of light at 1 metres distance for excellent peripheral visibility, while the spot provides a tight 20 cm diameter of light from 1 metres distance.
A simple push button on the top of the head torch controls all LED functions. Press the button once to turn the light on in high and then again to change to low and a third time to turn it off. The light can also be turned off in either mode by holding the button down for two seconds, and the last used mode will be remember if the light is turned off in this way. This is useful if you are using low mode and want the light to turn back on in the low setting rather than the high.
There is also two side red LEDs that can be accessed by holding the button down for 2 seconds. Red light preserves your night vision and is good for multiple tasks such as watching wildlife as the red light does not affect them like white light, on a campsite to not disturb your fellow campers, night reading and astronomy.
The lithium polymer 1000 mAh 3.7 V battery pack sits inside the main head lamp unit, by popping open the cover on the back, thus reducing the weight on the back of the head. The battery is easily charged back up by inserting the supplied USB charging cable into the micro USB port on the battery itself and then inserting the other end straight into a computer USB port, or a USB mains/car adaptor. This can be done with the battery still inside the torch by opening the battery compartment door, or it can be removed from the head torch. A red LED will illuminate to indicate that the unit is being charged and will go green when charging is complete.
As well as the lithium polymer battery pack, the H4-R can also be powered by three AAA alkaline batteries, which is useful if you are out camping and don't have a power source to recharge the battery.
The head torch can run up to 4 hours on high power down to 1 lumen, or 3 hours on high power down to 10% of maximum output. The head lamp can be tilted downwards so you can position the light where you need it.
Automatic temperature protection will reduce the light output if the headlamp becomes too warm after continuous use in order to protect the LED from overheating. Once the temperature drops the light output will increase again.
