hmm I set fire to anything when I was a kid with a magnifying glass..even a neighbours shed with lots of petrol in it....and a dumped car..dont give a 6yr old a good magnifying glass would be my tip of the day..

Quite right, for road use. For off road though, some light higher is useful to show low branches etc.

I do use mine off road and don't have an issue with seeing eye gougers and scalper branches. I find the less intense non centre throw of light does me ok there while still being gentle enough on the eyes of fellow road users.

That said, I always use full power off road and the generally the lower power setting on it.

I see that one of them is about the rigging of the Scottish independence referendum. Who do we know who has an interest in that topic and form for sock puppetry?

Nobbers everywhere.

A new CycleChat member who has made just one post, and that one post is saying how wonderful a product is?
Even without my tin foil hat on I'm not sure this new member has our community's best interests deep in his heart.

Reverse-pshycology spamming, well that's not really a new thing

P.S don't buy any of my novels, they all suck, your friends will laugh at you, lovers will spurn you and reading even a handful of my words can lead to genital warts.

Can you let National Grid know about this? I'm sure they'd like to know how you get this much output from a battery

For sh*ts and giggles I found a battery that will give you around 14kW for an hour or so - they seem to be used for solar panel storage. It cost £10,000 and weighed 280kg.

Ever put your hand near a lightbulb?

Hence their inefficiency as a light source compared to fluorescent, which have better energy usage due to the fact that they are producing light, not so much heat and light. LEDS produce heat, but within the device itself, often shielded from the environment by the enclosing material. They produce about thrice the amount of light for energy over incandescent light, however.

Old bottle generator and a battery light still get the job done for me.

So, stupid bright lights get hot. Who would have thought?
I've got a cree T6 LED torch that gets warm in use. Lump loads of them together in a housing without sufficient cooling and they'll get hotter and at Fahrenheit 451 auto ignite. Incidentally, Incidentally Ray Bradbury is a much better fiction writer than the OP.

There'd have to be an awful lot of infra red coming out of that LED lamp to burn paper, looks like BS to me.

I have a bright light light and I love it. They only cause a nuisance to others if the user is a fool.

The problem with 'bright lights' is in our frame of reference, no-one ever says 'I've got some dim lights on my bike' , even the pathetically feeble Smart 7 lumen city light looks 'bright'.

I must admit that I have to admire the integrity of the people who complain lights are too bright....

I have two "regulars"

One prevents blinding others by using an old green flashing LED visible at about 10m, and the other uses no lights at all

I can see why compared to their opinion of adequate lighting that mine is "excessive"

 

[shouldbeinbed]

The sort of person who insists on ducking down in front of you to see how bright it is?

ummmm *shuffles awkwardly on the spot* I forgot if I'd charged my rear light or not the other day, just to check I casually switched it on while it was pointing directly at my eyes.

I found out I had charged it and it is very bright at that proximity.

I need to start writing charts of this stuff.

Sort of a unified field theory?

According to the British Epilepsy Society, the only recorded fit caused by a bicycle light was in exactly this situation
