Right!

Some long term observations on these cree style models I bought about 18 months ago:

http://www.ebay.co.uk/itm/UltraFire-WF- ... 4171e0efff

Having to commute in temperatures of around 0c to -7c, these lights showed up their weaknesses. The cold killed of the circuit operation so the torch became pretty useless. Once switched on and out on the handlebars, as the cold penetrated the torch would be comes stuck in whichever mode you happened to have it on. The glass lens is very fragile and I found mine rattled. Also as I went over potholes and bumps the damn thing would change 'modes'. I found that the part that combines the reflector and LED had come slightly loose so the glass was free to move around and rattle.

A bit of blu-tac secured it but an 'O' ring would sort this out but it wouldnt prevent the cold issue.

Battery life was unaffected, 15 miles a night and they were charged once a week.

I have trawled through ebay and have found the later models have better sealing and a more robust finish which should address some of the above issues.


I also used two of them in late summer and they were amazing. 'Medium' was more than enough to light a dark country B road with oncoming cars dipping from a fare distance. The fixed beam is well spread.

Been running these for a number of years since I started this thread and they have stood up very well: http://www.ebay.co.uk/itm/Top-Quality-C ... 20cec33520

Standard AAA alkaline batteries last a few weeks with 1 to 2 hours use every day. The beam was just enough to see and be seen. To be seen was the most important requirement for me on a busy well lit A road.

I also have one of these on stand-by but found the battery holder useless on my road bike and will modify it sometime to suit. Finish is of very high standard when compare to the above, just let down by the rather naff nylon battery case. Chopper's idea of securing it in an innertube seems a good idea. I was able to compare these to a 2011 Exposure 6 pack, obviously not as good but for around a tenth of the money, I leave that up to you!

The whole reason I started this thread was due to the seemingly daft prices of some products and being a tight wad, I wanted to show that there were usable alternatives.

My latest purchase and I'm quite impressed for £27 delivered!
I bought the 4600mAh version and high beam so far has lasted me over an hour and still going, I've yet to see how long before it cuts out.

Below are comparisons with my old Hope Vision HID and Hope Vision 1. All pictures taken with no other light source and on a iPhone 5S

I bought one like that from DX, branded a Fandyfire, a couple of months back. Used it on a couple of rides and it's been OK so far. One of the rides was a 2+ hours ride at Glentress, didn't run it on high all the time, would switch it down to lower settings when not descending so don't know how long it would last constantly on high. Might get another in new year from the guy in earlier link as it's down to £24.99 and from UK so might get here quicker than 3 weeks.

That clamp on the hope vision one looks like their universal clamp. You should be able to use that instead of the rubber oring things on the new lamp.

I had the same thoughts but I think I would have to drill and tap the light to fit it and besides the Vision 1 is on commuter duty :-)

Assuming the Twin is fixed to the clamp in the same way the Single is, then you take the padding off and undo the Allen bolt under it, then fit the Universal clamp.

The clamps are only 8quid at CRC and well worth paying for. viewtopic.php?p=1484299#p1484299
