hey, i need a lamp that will light up the area around me HARDCORE, like within the 20 meter area. i dont mind paying whatever it costs im just torn between the myo rxp, duo5 and duo 14. dont see a buzillion flood light led's on the myo rxp like there is on the duo and im wondering if that will matter. any info will help. thanks

The defuser on the RXP really does a great job of spreading out the already bright beam. When you hit the boost button with the defuser up, it really lights up the night. On the lowest setting, which is 8 lumens, you can easily cook or I even was able to hike on less technical parts of the trail. I don't even use the 9 or 10 setting because its just to much and for the fact that those two settings aren't regulated.

The MYO RXP is rated greater than 20 meters at all program levels for several hours (varies with program level, but greatest is 35 hours/23 meters). The MYO RXP doesn't need the flood to maintain this output since it uses ultrabright LEDs. The DUO LED 5 is rated 70 meters at 30 minutes, 22 meters at 10 hours, and 9 meters at 30 hours (4xAA batteries); 24 meters for 12 hours with NiMH batteries. The DUO LED 14 is rated at (average), 34 meters through 3.5 hours and 9 meters at 10 hours at maximum power and 26 meters through 10 hours at optimum power. So, it all comes down to light/time. Since you need to light up 20 meters, use that as your constant and then go for the most time. The MYO RXP offers the most time for >20 meters at 35 hours (program 1) in addition to having several program levels, it also has a "boost" setting for up to 97 meters for short duration (but will reduce overall usable time significantly). It's the most versatile of the headlamps you mentioned. As for total battery life, the MYO RXP varies from 54 - 95 hours, DUO 5 = 65 hours for the 5 LEDs (AAx4 batteries) and 30 hours for the NiMH batteries, and the DUO 14 = 183.5 hours at maximum and 148 hours for optimum. Just looking at the numbers, the best battery performance is the DUO 14 followed by the MYO XRP. Overall, the MYO RXP looks like the best option, with the DUO LED 5 being the worst. I've presented the data here since I don't know what you need as far as light/time or what you need for overall battery life. Of course, if you want really hardcore lighting, the Petzl ULTRA would be the airport beacon on your head option. It illuminates up to 120 meters for 1.5 hours, 80 meters to 4.75 hours, and 40 meters for 16.75 hours. Battery life is short, however, with 2 hours, 5 hours, and 16 hours respectively.
