Not taken much notice of the P7 threads recently, but now looking for a new helmet light. Thinking of getting an Airbike SL2, But what are the other P7 options, make model, supplier, price etc.

mte p7 from dealextreme.com get the 2 mode, less hassle clciking to fing hi or lo than the 5 or 8 mode.

5 Mode P7 from deal-extreme, 2 version is ok the 5 version loads more versitile.

on and one of these http://www.dealextreme.com/details.dx/sku.2709 to convert the charger.

They aren’t the ideal helmet light IMO as they are a full-on flood rather than spot. So long as you are happy with a flood throw on your helmet light it will be fine. I use the 5-mode version on my bars and do find the mid setting useful (low is just too low)

Got an Airbike SL2 myself, though only handlebar mounted. It’s a good light, better than the P7 torches? Well it’s got a convenient battery pack that lasts a full 3 hours on full beam, so its more convenient by some margin.

That said, I spoke to Planet X and they don’t have any helmet mounts for it, or any cable extensions (the current cable is too short to mount he unit on your head with the battery in your camelbak), and don’t plan to do so it seems. Could of course make your own though!

Regarding the P7 torches, the one that z1ppy pointed out is not a "C Bin" meaning it’s not the latest and prightest P7, that said it’s probably the cheapest and 5 modes means you can alter its brightness a bit. Having a P7 light (My airbike SL2) on the bars, I wanted something with a bit more of a spot beam on my lid and went for one of these:

It’s the same LED as in the Exposure Joystick (and the same as Hope use in their Vision 1 light) but a fraction of the cost. It adds a useful spot when you’re riding downhill anyway. The fact it will last over 2.5 hours on a full charged battery is also a bonus too, as it minimises the need to swap a battery whilst out on a ride.

That said, I’ve since noticed a much smaller/lighter unit on dealextreme:

It uses the older Q5 Led rather than a new R2, but it’s only 20 Lumens less output. But the unit is about half of the weight of the R2 torch I bought (which in itself is not heavy), so you could use 2 of them on your helmet, for the equivalent output of a Hope Vision 2, for about £40 all up including batteries and a charger!

Oh, and just a word when it comes to Lumens. Those P7 torches may boast 900 Lumens, but in reality the beam patterns are often too much of a flood to make them totally usable anyway. From what I’ve heard, most are more like 500 Lumens anyway (which is still a lot of light for the price indeed!). The smaller Cree units tend to be more of a spot beam (better for helmet mounted use) and throw a REALLY long way (my R2 will light up a small spot in the centre 50 metres away easily), and their quoted Lumen output is generally closer to that actually acheived.

All the P7 lights and torches I have seen use a reflector and lense rather than an optic (which would give a better spot?) – any reason why this is?

Regarding the P7 torches, the one that z1ppy pointed out is not a “C Bin”

I was informed that it was.

Very confusing all these P7 threads – bike? Torch? 😆

I’d go for a 2 mode for the helmet.
