FWIW, I have recently purchased a customDUO insert to replace the halogen bulb in the headlamp (see details below). This was intended to complement the 14-LED side module in the headlamp. It took about 4 weeks to ship from the UK, and I received it in time to install it on the first evening of the TSA Convention in my Petzl Duo headlamp. Installation was really simple and only required a small screwdriver from my Leatherman tool. Several cavers joined me in walking off into the woods to compare the light output of this insert (cost: about $100) with a Stenlight S7 (cost: about $310 for the standard version, including charger and extra battery; $60 extra for version with premium LEDs) and a Scurion 700 model (cost: about $700, including spare battery and charger).
Verdict: customDUO insert compares favorably in light output to the Stenlight S7 on highest setting, and to the Scurion700 on lowest setting. The beam pattern is intermediate between the highly focused Stenlight and the very diffuse low setting of the Scurion. Details about insert: cd701-XPG twins, two Cree XPG LEDs, focussed and full flood. Smooth spot optic. Single mode (700 mA regulated) providing 280 lumens. R4 neutral white LEDs. I have not had the opportunity yet to test this on a caving trip, but will report on my impressions of the insert once I get the chance.
