After unsatisfactory duration of burn in my Spiderfire B200 I decided a second light was necessary. Ideally this one would have a three hour burn time. After searching for a while I found the Hope Vision One LED Bike Light from wiggle.co.uk and purchased it with the added bonus that it runs on 4 AA batteries. Having just purchased 16 AA batteries of 2600mah rating I thought this was a good thing.
The unit only required the mount to be assembled. It warned of being careful with one of the bolts and the rubber ‘o’ ring. I dropped it a couple of times but it wasn’t that tricky. The drops were mainly from rushing. I was excited: this was the light to solve all my lighting issues.
The mount has a lever-actuated cam to lock the clamp into place. I had to put two rubber inserts into the clamp-rings to fit my bars. I think the clamp is intended for larger diameter bars (30mm?). The mechanism is quite clever. Not to be left on the bike where a risk of theft exists. It’s very easy to remove.
Mounted it doesn’t look that big. It’s a little smaller than my venerable old Cateye HL500: which runs on twin C-cells.
The fit of the screw-cap is excellent. Threading is very accurate and it tightens nicely. I did find it a tad disappointing that the battery-pack was made in Taiwan when Hope say the light is made in the UK. This is kind of accurate in lawyer-snake-speak as the light-body was made there (assembled). The battery-pack looks a little cheap but I don’t think it needs to be that robust. Time will tell, though.
The Hope Vision One is operated by a domed button on the body.
- First press turns it on in “low” mode.
- Second press and it ups-output to “medium” mode.
- Third press and the output is at “high” mode.
- Fourth press and the output is at “max” mode. It’s spec’d to get 3hours on this mode out of 4 AA 2700mah batteries.
- Fifth press and it goes to “flash” which is a flashing “low” mode.
It’s a pain that flash is last. It should be first. The light is fussy about voltage and will shutdown without warning if it doesn’t receive the correct voltage. When your batteries are low it would be good to swap to flash mode to get some light until the batteries are drained. You cannot do this because you have to go to “max” and drained batteries will mean the light shuts down as you enter “max”. This is the only functional flaw of the light.
Overall I think the Hope Vision One is an excellent light with one weakness: having “flash” mode after “max”, preventing its use with drained batteries which is when one would need to go to “flash” so there’s some light rather than none.
