Well, as promised I'm reporting back on the Ultrafire C8 Cree 390 lumen torch that I posted about further up the thread.
Ordered on 22/7/10 from the Hong Kong eBay outlet and delivered yesterday (28/7) via airmail for a £17.99 Paypal payment - and they marked the packet up as a 'Gift' without any prompting from me.
First impressions are very favourable. It's a small but chunky piece of anodised (?) machined aluminium with all the right O rings and a good looking reflector in a large diameter head. It comes with a 3.9V rechargeable battery that looks like an AA on steroids, plus a 240v charger that has a couple of flat blade pins on it. I'm sure I've an adapter somewhere but if not I'll do a direct connection to a 3 pin plug.
The light emmitter is retina scorching - as someone here found out when they switched it on while looking into it! The fixed focus beam is tight and without much scatter and will be ideal for me to at least 60 metres and maybe beyond, (that's in our lane, I'll give it a better assessment tonight in the field), so I'm going to swap it for the Lenser P7 on the Mossberg.
The other advantage it has over the Lenser is that the Ultrafire has a simple base on/off switch. The Lenser has a press and hold for maximum, release for 80% and click again for low power - good for general hand use but not so good gun mounted.
All in all it's looking a good buy for the price but maybe as someone said earlier, one of the higher output jobs will be a better option if you're looking to push things out to 100 metres plus.
