I just removed all characters from the URL from the '?' onwards, and then it worked fine.il padrone wrote:Linky..... she no work!
Couldn't help laughing at their "Mil-Spec" claim, though. I wonder which military specification document they claim their product conforms to? I'm more interested in how much the light + battery weigh, something they've omitted from the description (or at least Cell Bikes' description).
By the way, in response to the OP: here's a review of a similar light: http://reviews.this link is broken/product ... Light.html

use code 'BLF' for $44.21
I'm banking on the range of settings covering my needs for the upcoming winter.

Agree your point about aiming concentric beam lights. PITA. My partial solution is to aim my helmet to the left when passing oncoming cyclists through narrow spaces like the SHB cycleway.MattyK wrote:^ This guy gets it.rdp_au wrote:.... Recently, the Philips Safety Light was on special and I was able to pick one up for $80 delivered. My initial impressions are that it will work very well as a proper road light. The optics are designed to comply with European regulations which require a cutoff to prevent dazzling oncoming road users. This works very well, as there is a broad and fairly even spread of light from close to the front wheel out to a long way down the road. The beam is also wide so it spreads out to light up the sides of the road as well. Comparing the two lights while standing about 20 metres in front of the bike parked in my driveway is interesting. The AYUPs are very bright and quite dazzling - as to be expected. The Philips looks just like a car headlight on dipped beam.
You just can't achieve the same effect by tilting a concentric beam pattern light downwards. All it does is blow out the foreground exposure and reduce the distance illumination, and it still doesn't eliminate the glare.
Very interested to try lights with a cutoff beam off-road to see the difference.
I suspect it would be excellent for groomed race courses like the Mont 24 where proper attention is given to keeping the high part of the trail corridor clear of head-height "coathanger" obstacles, but unfortunately our local trails don't seem to get that attention from land managers and I frequently smack my helmet on low branches as it is
An arrangement similar to car head lights where an additional bulb (LED) comes into play to change the beam pattern would be required, I suspect.

No cut-off beam however, it runs triple concentric-beam LEDs.The E3 Triple was developed for 24h MTB-races and is used successfully by the Supernova Racing Team. Even Olympic gold medal winner Bart Brentjens and his 4-man team put their faith in the E3 Triple at the 24h-race of the Nuerburg- ring, Germany, winning the race with this dynamo light.
The Big Bang was a light designed to cope with both off-road high beam, and a cut-off, dazzle-free lens that meets the German road rules on bike lights. It was hugely expensive and HID rather than LED, but is no longer listed by Supernova on their range.

Does that say it has a 30 minute run time? Seems a little on the short side.Jonno wrote:I just purchased this one:

As TG hinted at, I really think the Luxos would miss out on the trail foliage judgement stakes. It is designed as an excellent on-road commuter/touring light really.

Aah, so this is the more recent reasoning. I must have misunderstood your earlier post from which I thought the problem was with the "victim"not having flash enough lighting.trailgumby wrote:Do you think I am the only one around Sydney having AyUps on my commuter bike? So long as I avoid looking directly at the oncoming lights I have no problem with being dazzled. Yes it is a little bit uncomfortable, but so what? You just just deal with it. It really isn't that hard.
In that respect it is no different to dealing with oncoming car headlights on country roads. You just look down and to the left of the opposing lights. They need to have enough light to be able to see where they are going too. I don't see how bikes should not be afforded the same allowance.
As I do not stare directly at bright lights coming at me any more than I do when driving, I still can't work out why my more than adequate headlight is still inadequate during the dark mornings half a dozen times a day to allow me to see well enough not to have to rely on trust that I am still staying on path and prior knowledge of what is underfoot. Perhaps you have another explanation? Other than the obvious one of course - that some people just have unreasonably bright lights.trailgumby wrote:The only whingers are those with idiotically inadequate or no lights. Complaining about my lights when you are a dark indeterminate barely detectable object heading in my direction on a possible collision course, well, i make no apology for reflexively giving you my headlight spot beam to work out what sort of threat you might be. Harden up and get some better lights you can see by you goose.
Back in the real world I do suffer some unplanned dismounts directly caused by an inability to see a depression or a tree-root damaged path. Perhaps one day it will be a brick or rock that does not belong. Not something for which I thank twats indulging in an "arms race" to the best and biggest set of spotties.

But isn't this the cause of the misunderstanding? Your acceptance that a brick or rock will knock you off cause you didnt see it is someone elses (mine included) version of not bright enough.ColinOldnCranky wrote:Back in the real world I do suffer some unplanned dismounts directly caused by an inability to see a depression or a tree-root damaged path.

Am I only allowed one reason? Interesting.ColinOldnCranky wrote:Aah, so this is the more recent reasoning. I must have misunderstood your earlier post from which I thought the problem was with the "victim"not having flash enough lighting.
Those riders that are visible, I am conscientious to avoid dazzling by pointing my helmet lights away. Sometimes I forget, but not often.
Of the half-dozen or so who've complained to (or at) me in the last 18 months or so, the strike rate is 100%: they've either been ninjas without any lights at all, or their lights were so close to dead they might as well have been unlit ninjas. Do they really believe a single LED powered by an almost-dead watch battery does anything to help others see them?
I mean this seriously, what do they realistically expect people to do? They're as good as invisible, a collision waiting to happen, how is it they can be surprised people feel the need to use their lights to identify what they are and confirm they're not going to collide?
Maybe they're just a bit dim (pun intended).
