Sorry for not getting back to this sooner, it was not going to be possible to reply correctly to all points raised truing to tip it on the iPhone.
I have though long and hard about replying and defending myself against this attack on me, in case it is viewed as ME trying to bait others..But I feel i must try and defend what I have said. Apologies if that is wrong.
And you need to realize it's harder than that to insult the intelligence of those who know what's what. We don't play "Heh heh heh, this is for, um, 'off road usage', heh heh heh, wink wink" games here.
I am not playing those games at all..If i'd want t for road use I'd happily say so, and take the flak for it. I am not trying to insult anyone. I am just pointing out what I had already said and that it was in the first post.
I know I don't know
what's what (to use your words) and I am not trying to insult anyones intelligence. This is why i am here to ask.
If any one has been insulted I feel it is me, in that you are thinking that I am playing games and using the 'nudge nudge' wink wink 'it is only for off road use'. When I say it is for off road use, that I mean that.
I don't feel I have done any trolling or baiting at all. I already stated it was not for road use. I am very concerned NOT TO blind people on the road. If my link had been followed to my earlier post it can be seen that, I am also on the lookout for a proper on road bicycle light with correct road angled high low dip beam.
It is of great concern to me that there are so many people going around with badly adjusted lights blinding on-coming cars. I can see legislation coming soon over here, there is already concern begin raised in the local newspapers. The last thing I want to do is to draw more attention to myself by blinding people and causing accidents.
It is an insult to me that you feel I would do that.
As you correctly noted I did say
might even be usable on road with a suitable beam angle and reflector..but
Note the words "
might" &
suitable beam angle and reflector. If it was suitable adjusted to throw a pool of light to the ground with a sharp cut off, so not to blind it
might be usable as a road lamp. But that is not what i am after as I have stated.
If there is any baiting going on i'd say it was begin done to me, in the deliberate ignoring and disbelief of what i am saying.
a car headlight, when you are on the road and being tailgated, the car lights instantly our class and swamp your bike lights.
Really? Interesting. I haven't noticed that effect at all when I'm riding my e-bike off road, probably because there aren't a lot of tailgating cars off road.
Who was talking of it happening off road? I was replying to SemiMans answer about car head light brightness and my experience ON road with my current bike light setup. There was no mention of off road, it was a discussion of perceived brightness of car lights and their lumen output in relation to bike lights and the perceived brightness on the road, caused by reflector design.
So I can't work out if this is another deliberate attempt to bait me or really misunderstanding of what was being discussed. I am assuming the latter.
This is that quote, from part of that discussion with SemiMan about the current brightness
SemiMan said
You don't need 10,000 lumens for an e-bike, on or off the road and certainly never-ever on road. Car headlights, low beams, are 1/10 this.
So he was saying are lamps are around 1000 lumen. and I was saying I was not so sure about that , but I do have a basic understanding of the subject. So, I
can understand how it could be, that a 1000lumen car lamp, (well 2000 if both lamps are working on the car), could give a much greater and brighter pool of light than my small single De Noitte lamp, with a manufacturers figure of 2100 lumen.
Lumens/ lux etc, and what it appears as, All I know is that I have a De Noitte lamp..they claim 1600 lumen...and car lamps appear much much brighter when a car approaches from behind, the bike light is soon swamped with the 'volume' of light from the less bright car lights.
edit ..actually they claim 2100 lumen

I know vaguely the difference between lux/ light levels per square unit area etc...I am not totally blind to the issues, but it would just be crazy..no more need than guys that have stupid power audio systems in the ri cars.
Not going to go around on the road blinding people ..and getting cyclist a bad name...check out my earlier post about proper dip bicycle headlamps for road use. Damn what is needed, I want to know if I can make a a portable 16,000 lumen flood lamp that i can power off my 20s4p 20 Ah bike pack
I do still want to know how I can do it. I don't like upsetting people, and I am sorry if anything i have said has come across that way. But I am only responding to what others have said.
Yes I do have a powerful e-bike, but still it is not as OTT as many out there. When I first built it it was a lot more powerful, as I overbuilt it. I used to run it all the time at 24 series (100volts). Now generally only 20 series charged to 4.0- 4.1 per cell, so 80 volts hot off charger. I have de tuned the controller to limit the power and current to a max draw of about 50 amps from the battery, where it used to pull 140 peaks.
I actually live in Jersey, which is an island, and although part of the UK, we have our own government and laws, so UK regs don't apply to us here in Jersey, although we do have similar. I have discussed my bike with people at the local vehicle inspection authority offices, and although they have similar regs in Jersey, they are not interested as long as I don't go around building them for others and acting a total idiot on the roads. Which I 100% do not do. I actually get often passed on the shared cycle paths by hooligans riding like idiots amongst pedestrians. Just because you have a vehicle that is fast does not mean you ride or drive it at that speed everywhere.
I had stated what I was wanting it for in the very first line of my first post, I also mentioned that it would need a suitable beam angle and reflector
IF it were ever to be needed to be used for road use. I even linked to a thread of mine where I was asking about a road use bike lamp with proper high low Dip beam , not just high low power. For my use as a portable flood lamp powered from my bike pack, I did not think I need one. But it was certainly considered as I mention it being needed if I wanted it for road use. If you feel as a flood lamp it will too need some sort of reflector then i am oped to suggestions.
Some bike lamps have high / low power, but not easy to access while riding, they are usually buttons on the lamp, and not a switch on a wire that can be fitted on the bars in easy reach of the hand. Any high / low lamps are certainly not beam shaping.
I have actually been in discussion via e-mail with Bruce Barnes from Phoenix Electroformed Products to see if they had anything like a high / low dip beam reflector available for LED lighting units, or if not what the process would be to get something made to do the job. Justin from ebike.ca tells me they do have a proper high low lamp in design at the moment, so i am trying to get details of their reflector unit.
