Unless also riding to and from the trails most folk rarely ever ride for more than 2 hours* at night.

I get where you're coming from and the approx 600g of weight is not enough to worry about or to slow me down on my night jaunts. I would say on average my night rides are roughly 3 hours + with riding too and from the woods, the dimmer the lights yes your eyes do adapt, but you also have to ride slower to see all the obstacles. watch my video above to see the difference it makes riding around the local woods.I know we all would like a zillion lumens and would love to show how much brighter it is at night with our lights than during a cloudy day where we wouldn't even consider using a light, but seriously guys these lights you are promoting are really heavy weights, literally from all the battery power on board.
Can I ask the question ? Your eyesight will and does get acclimatised to the dimmer 2000 lumen lights, do we really need all the additional weight and cost to actually enjoy riding at night, particularly as it would seem most of you are having to run at lower settings to even get two hours of riding, carrying all the extra weight that will give you two minutes of max power.

I beg to differ Gary, at short distances you need a wide beam to flood the area with light, you need peripheral as well as directional to see obstacles and dangers at shorter distances that more often than not are not in line with your bars. The cheaper Chinese lights use exactly the same Cree T6 LED’s as their more expensive counterparts, which in the smaller lense format of say the X2 do not have the precision of the more expensive lights and thus are more suited to flood duties.If you're going to use cheap lights, for obvious reasons a bar mounted flood along with more of a spot helmet mounted would be the way to go rather than the other way around.
But even then cheap lights do not all offer the same quality of light or even colour of light.
flogging a dead horse about how great your cheap lights are to a bunch of folk who already have far better lights is a bit futile don't you think?
Thought you might.I beg to differ Gary
Lets ignore stupid amounts of lumen lights that last for a few minutes before throttling back ( heat ) and lets talk about the 2K to 4K lumen lights which can last for a minimum of 2 hours at that rate, which I'm probably meaning both cheapo Chinese and some of the more expensive lights out there.Thought you might.
I can't even be bothered explaining why you're wrong. You are though.
You need to substantiate that Gary, I know you only seem to ride road bikes and I can understand that perhaps roadies are different to mtb riders in their requirements, but from where I'm sitting you are talking a load of bollocks and wishing to denigrate personally rather than have actual factual proof of your statements . Certainly we gave up with spots on our helmets due to the shadowing problems an intense very directional light gave.Flood on the bars and spot on the lid has been the fairly widely recognised ideal combination for off road riding and has been for the last few decades. Until you came along Wayne.
You see thats actually quite hard to do as there's almost no scientific testing over varied testers and terrain on the internet, other than light tests of the latest and greatest all purporting to be the best from 1 - 10 with 3/4's of them almost totally impractical in the real world due to size and weight and low run times. Seems the advertising and branding world at one of its best examples.That goes both ways Wayne...

So lets have a bit of actual proof rather than Gary's internet based " hearsay ".
Stop poking the bear mate.You see thats actually quite hard to do as there's almost no scientific testing over varied testers and terrain on the internet
Just to confirm, as this thread has gone off topic a few times, we are still talking bikes aren't we ?but I don't have the spare dosh to blow on something that'll get used a few rides per year
I'm sorry. It gets confusing. We have people saying Lights aren't light enough and then some say the heavier ones are often lighter .....Lights Zim, we're talking about lights.
No. We were enjoying riding our bikes with shit lights rather than getting into pissing contests with people we’ll probably never meet.Were we getting the same fights over the benefits of 20w cateye halogen
How come the pissing contest evolved around showing your superiority by pissing higher or further than someone else ?No. We were enjoying riding our bikes with shit lights rather than getting into pissing contests with people we’ll probably never meet.
It's not quite that simple, unfortunately. The triple optic (khatod or carclo by the looks of it) is patterned like that partly to reduce beam artifacts from the LED's you can swap them out for different beam patterns if you want. The LEDs dies are physically bigger in said triple, this requires a bigger individual optic to focus the light Into something useable. I don't know exposure stuff, but it's probably got the xm-l sized emitters in there.I haven't read(yet) the above squabble, but the 'bike' package I had from Exposure was the Diablo head torch and the MaxX D bar mounted torch.
the Diablo helmet torch has 3 LED's and each one has a diffuser lens in front of it helping to emit a spread/wide light.
the MaXx D has 4 LED's and only one has a diffuser lens in front of it to give a more directional long throw of light.
So according to Exposure.... wider spread on helmet, directional on bars
to illustrate, here's the MaXx D, take note of the bottom lens....

Interesting and always open to learn from more erudite people. Can I have a clarification please. You quote the four LED unit as the helmet unit when in fact it’s the three LED unit, can I ask you to comment please.It's not quite that simple, unfortunately. The triple optic (khatod or carclo by the looks of it) is patterned like that partly to reduce beam artifacts from the LED's you can swap them out for different beam patterns if you want.

I don't know exposure stuff, but it's probably got the xm-l sized emitters in there.
The quad you have as a helmet light is using a custom designed optic, as you rightly said the lower one will give you a long, narrow beam to illuminate down the trail, the others are there for spread. The individual optics are smaller because the LED dies are physically smaller, probably xp-g sized. These naturally throw more light down the trail and are easier to focus.
Most light manufacturers just use an off the shelf optic that fits the bill. Manufacturers have been known to tighten the beam up and throw it further down the trail because it's what people perceive to be 'bright'. Lots of lovely side spill costs lumens, lots of lumens, but a nice wide beam on the bars is the way I do it, a tight beam just looks like you're waving a light sabre through the trees
Now, your head is a perfectly stable platform. It stays dead level and true, for your eyes and that. So I run a spot beam on my helmet. It goes where I look, and I don't want the weight of a 3000 lumen light strapped to my head.
