Was out last night with a group, mostly running new LED lights of some sort, though a couple were still using Halogen Lumi’s. Anyway, Was running the Airbike SL2 P7 light on my bars as per usual, and my new MTE P7 on my head for a bit extra.
My P7 is the 2 mode like this one rather than the 5 mode (I have a 5 mode R2 which is great too, but I find the 5 modes annoying), and used it on low mode for most stuff, whilst keeping the Airbike SL2 on my bars in low or medium setting, then for any DH stuff, I upped them both to full power, and had a combined 1800 Lumens or therabouts! It was like riding in broad daylight! Nobody else’s lights even came close by comparison.
Waiting to find out how long the battery lasts on low power, but I’m told over 5 hours. On a 90 minute ride last night, switching the light off when we stopped, keeping it on low for most things, then on high for the DH bits, the battery is still nowhere near flat. So Just keeping one spare battery with me should be plenty even for most uses.
