Petzl e+LITE
Petzl introduced their e+LITE "emergency headlamp," the smallest headlamp in their line. There are a trio of 5mm white LEDs and a 3mm red LED. Weight is 0.9 oz (26 g) with its pair of 2032 3v lithium coin cells (10 year storage life). Packed in its storage case, it weighs 1.6 oz (45g). There's a lever action switch to the side of the LEDs with 8 positions. In the lock position, the switch handle is almost flush with the case to help prevent inadvertent switching, Rotating counterclockwise (when looking at ti form the front) the switch positions are: Off, Economy (low brightness), High, Flashing White, Flashing Red, Steady Red and then another OFF position. The switch is easy to operate one handed and once moved off the Lock position, can be operated with heavy gloves on.
To give you an idea of scale, the circular switch portion of the e+LITE is almost exactly the size of a quarter.
The single elastic headband has a plastic cord-lock style slide for quick adjustment. The plunger on this also does double duty as a tool to open the battery compartment. The light can be removed from the headband easily via slotted attach points and then can be clipped to a cap or clothing using a broad spring clip that's integrated into the backplate. This spring clip will only accommodate relatively thin surfaces; a cap visor would be about the maximum. Using the clip, the easy way is to slip it onto a stiff mounting point, such as a visor, because it was a bit difficult to manipulate manually (think: paper clip). It does not squeeze open like a conventional clip.
For storage the backplate is folded up against the face of the light. For use, it rotates behind the case using a ball and socket attachment on the bottom of the light, presenting a smooth surface to your head. This ball and socket allows a wide range of adjustment both up and down and side to side.
It comes in a translucent red hard plastic storage case with its slip-on cap held in place with an o-ring that wraps around the perimeter of the case. The light itself has a black body with red switch and backplate. It's rated waterproof to 1 meter.
At $30 MSRP, the e+LITE costs twice that of my current favorite micro-headlamp,
Essential Gear's eQ Hands-Free Multi-Light (which is also available as a
Doug Ritter Special Edition with a yellow case). With three LEDs, on high setting battery life is rated at 35 hours, but would inevitably be at least half to one-third compared to the eQ with a single LED and the same batteries. Petzel claims 45 hours on the "economic" setting." Petzel claims 16 lumens on high in a flood pattern, no focusing lens, but it's difficult to compare output since there is no industry standard. Subjectively, it is certainly brighter than the single LED eQ at short ranges, with wider illumination, but the difference is much narrower at longer range when the lens comes into its own. On economy the e+LITE is quite a bit dimmer than the single LED eQ, but plenty adequate for reading and finding your way down a trail or around camp in the dark. Options are nice.
Bottom line is that it performs quite a few more tricks, at the expense of the KISS principle and a much higher price. Still, the price is quite reasonable for all that's there. Any way you look at it, it appears to be a very nice package and very well thought out. Availability is listed as January 2007, though the Petzl representative indicated there may be limited availability for the 2006 Holiday season.
