Petzl MYO 370 Myo series is after the Tiikka one of the most recognizable headlamps on the market. Over the years it has undergone only minor changes, new colors,  updated regulated driver in the RXP version, this time it gets a new LED which allowed her to catch up with the fast fleeing competition again.

 

Some marketing data.

Petzl MYO 370 - 2015 back

Powerful multi-beam headlamp intended for endurance-oriented outdoor activities. 370 lumens.

The MYO RXP headlamp is perfectly adapted to endurance activities, thanks to its balanced weight distribution on the head. It is equipped with a flip-up wide angle lens that can shift instantly from a wide beam (proximity lighting) to a focused beam (long-range vision).

CONSTANT LIGHTING technology for Economic and Optimum modes:

- brightness does not decrease gradually as the batteries drain

- automatically switches to reserve mode when batteries are nearly spent

STANDARD LIGHTING technology in Maximum mode, it also has Boost mode (370 lumens), which offers temporary access to maximum power.

Okay, that would be enough of a press release...

What's new for the user ?

New colors - there is nothing better than a white headband ;-). The user will have a motivation to wash it (quite frequently).

Looking closely you can see the old optics and quite distinctive shape of the Cree XP-G2 led.

Ok, there is a new LED, but does it change anything for the user ? Comparing the specifications of the old Myor RXP with the new MYO 370 the differences are quite obvious.

Ib the highest mode we are getting twice the light output, in regulated mode (6-optimal) the increase is similar 110 vs 63 lumens and the burn time rises from 3 to 5 hours. In addition we are getting one more regulated mode n. 9 - 170 lumens for 2 hours.

There is almost no increase in range, It is caused by the use of old collimator designed for the Luxeon I LED - basically the new MYO 370 is modded version of MYO RXP 2 - you need only to replace the LED.

How does it light ?

Summary.

It's good but it could have been better. I still do not know why Petzl chose not to use dedicated optics for the Cree XP-G2, which would greatly improve the range and eliminate some of the artifacts from the beam of light (on the wall, the light spot is a bit rectangular). Probably they will wait 2 more years for another update ;). However, the new MYO 370 is still one of the best and most versatile headlamps on the market - it can be seen even after the number of headlamps sold on eBay.

Remember about one thing, before You buy the new MYO it is worth to consider to modify your old XP or RXP, especially that the new Cree XP-G3 are widely available.

And so the new Myo 370 could easily be Myo 450 cool, but that would probably be too much competition for Petzl NAO money-mouth.
