Petzl E87 P2 Myo RXP 2 Headlamp

I'll keep it short.... this light works great! I was hesitant about jogging with a light on my head but this thing changed my mind right when I put it on. The weight is so minimal and evenly balanced that you barely even notice it's there. It feels much the same as a normal head/sweatband. The Flood lens is amazing. It illuminates about a 10 x 10 area in front of me so I have no trouble seeing my surrounding. Battery life might be a concern if you use the highest setting (10). I use setting 4 and the battery indicator is still in the green after two weeks of use. Bottom line.... this thing feels, looks, and works great!

After doing a lot of research on headlamps, I have found that their performance relies on the limitations of battery technology. Unfortunately, society has still not discovered a way to get more power output from a much smaller battery cell.... yet. This headlamp requires 3 AA batteries and places the battery case on the back of the head. I do like this design of putting the battery weight in the back, instead of putting a lot of weight on the forehead where the lamp is located. Three AA batteries would be too heavy in the front. In comparison to my Petzl Tikka XP that uses three AAA batteries on the forehead, this Myo RXP lamp produces a lot brighter light output and a different beam color (a warmer yellowish color). The visibility is definitely better. Lumen output is brighter, although on the brightest regulated setting the batteries won't last long unless you are using an unregulated setting.I also looked at headlamps that use rechargeable battery packs but did not like the lack of flexibility in those; if you're outdoors away from power sources, how are you to change out batteries? Or on a trip and you forget an extra battery pack, you cannot stop by a convenience store to pick up extra batteries unless the pack also can use conventional batteries. That seemed like too much trouble, so I stuck with a headlamp that uses conventional batteries for easy replacement.The reason for purchase of this lamp was for ultradistance trail running/races with extended periods of running in the dark. However, I haven't tested it for a full night's run but would expect at least one battery change for such an application.It's a versatile headlamp and I think if you own just this one, it will cover most of your needs as a nighttime trail runner or around the house if you're fixing something in the dark like car repair or plumbing.

After seeing a review of the same problem "wire going into the housing non-functional after approx. 3 years"... I returned it and purchased a NAO

I bought Petzl MYO RXP to replace a $9 4 LED Energizer headlamp (3 AAA HomeDepot style) which I used for several years while nighttime road running. My review is relative to that type of light.I typically run between 8 and 20 miles, occasionally more. Pace is typically between 8 min / mile and 9:30 min / mile [not a pro :) ]. I feel the three major features of any running light are illumination, battery life, and comfort.Illumination:The MYO RXP can certainly throw out some light!! The brightness levels are adjustable, 1 (dim) to 10 (bright). The MYO on 10 is much brighter than the Energizer light. However, the Energizer (with all 4 LEDs on) is brighter than the MYO on settings below 7.The MYO has a light diffuser 'flap' which spreads the light evenly on the ground. The Energizer light has no equivalent feature.Depth perception can be a problem with the Energizer light; colors are washed out and uneven surfaces look flat. The MYO RXP with the diffuser flap up provides much better depth and color perception. With the diffuser flap down (spotlight mode), depth perception using is better than the Energizer, but not as good as when the flap is up.I recently ran a night 10k Trail race and used setting 10 with the diffuser up (most of the time), and had no problem seeing the trail and picking a line over roots, rocks, and holes.Battery life:The MYO on 10 eats 3 AA batteries very quickly. The light will begin to dim a little in just a few hours. Settings below 7 do allow for consistent light on longer runs, but only average lighting. The Energizer light stays bright for hours and hours and hours. I think I only changed the 3 AAA batteries every few months - and then only because I thought I should. In my opinion the Energizer is far more energy efficient (cheaper to run) than the MYO.Comfort:This is again a relative category, having a light on your head while running simply isn't that comfortable. That said, the MYO and Energizer have tradeoffs: The Energizer light is much lighter than the MYO, and the weight is all up front. It just has a small foam pad that presses on a single spot which is irritating after a couple hours. (I wore a head sweatband under the light to make it more comfortable)The MYO's lamp (front part) is very light and fits great on my forehead (lamp to skin). But the battery pack is so heavy (because of the 3 AA batteries) that it constantly slides down the back of my head until the strap hits my ears. I do not like this. There is a top strap included with the MYO that does keep the back in place, but I feel like a dork when using it. I have been wearing my Brooks running hat (baseball style) turned backwards, with the lamp resting on the hat's adjustment strap and the battery pack supported by the hat's visor. This set up works fairly well.In my opinion, the MYO is a good light and better for trail running than an Energizer light. If you run roads only, the Energizer is sufficient and far cheaper.

I'm a dental hygienist. I'm using this light at work. It's perfect for me. From my sitting distance, the pt's eye doesn't get blinded. It illuminates an area just large enough so I can see their mouth. This device is more useful than my loupes. It's far too difficult to move the overhead around constantly. To have a source of light coming directly from the point of view of the eyes is most useful.I use three AA rechargeable and charge them overnight. I have the default setting on "7". It was originally 9 I think, however, I could only get through about 4 or 5 pts. I turned the intensity down a bit and experimented. Now I can get through all my pts through the day (sometimes I see 8 pts) and it's not a problem. It is just bright enough to see.My previous MYO XP did not allow me to adjust the intensity of the light. I really like this model. It is really flexible. The DDS I work with has also purchased one of these. He uses it on the brightest setting which is really bright. He goes through batteries like crazy and simply has 2 sets of batteries that he charges throughout the day.
