This delivers great close proximity lighting and has more beam power levels than any light we tested. The extra "R" in RXP stands for "regulated" as you there are three lighting modes, for each of which the user can select the power from among ten possible levels, from 8 to 140 lumens. While this feature sounds cool, we didn't find we used it. The three default levels that the headlamp comes with are fine. We did find a big drawback to the regulated feature: the battery life was not nearly as good as the MYO XP. Whereas the MYO XP had one of the longest battery lives of any headlamp tested, the RXP was just OK in our tests. Due to that and the fact that the RXP is $15 more expensive, we recommend you stick with the standard MYO XP. For the price of the RXP, you can get the super bright Black Diamond Icon or nearly get three Coast HL7 headlamps.
The MYO RXP is a programmable model of the Petzl MYO XP headlamp. Overall, these two headlamps are similar in their brightness and functionality.
