Needed a headlamp for photography at night and did not want to spend a fortune. This lamp, with three red LEDs, does just that. The mechanism is a little "fiddly" - but at the price OK: One must be careful when inserting the little three AAA batteries that the "O-Ring" is not lost and remains in its position. So you should not need to change the batteries at night.
The white light is enough to find the way, the red light enough to find in the dark, the buttons on the camera on the tripod and not to be too blinded. The batteries are in the front housing (some lamps have two housing front the lamp, behind the battery) - this ensures a small pack size in the camera bag.
