Thought you meant on-one.

Does look pretty good, wonder how it will compare to exposure and such.

Meh it's nothing special and severely overpriced, uses a p7 emitter that is common to the dx torches people have for about £30.

Hang fire for the xpg emitters that are out end of the month, 4 of those will net you 1300/1400 lumens with about the same draw as a p7, make of that what you will.

Btw it's not 900 lumens more like 6/700 max.

Absolute rip off.

looks alot like the Nukeproof reactor

which happens to be cheaper

I just fell off the sofa looking at the price.

So who's producing lights with these new emitters for us MTBers?

1300/1400 lumens FFS, so what the point in riding at night, christ it'd be like strapping a football floodlight to your bars.


mind could blind a few twat drivers.

Depends... If you like night riding in low light, then even the 700 lumen lights are too much really, but if you just like riding and it happens that you're riding at night, rather than specifically out to do a night ride, then more could be better.

Though... I think the lumens arms race should be just about done now, these modern lights are pretty fantastic in terms of output, personalyl I don't feel I need more at all. But the XPGs don't just produce more light, they're more efficient too so instead of chasing big numbers, we should soon be looking at medium settings which produce all the light of the current P7s on full, with 50% or more extra burn time. And then that can lead to smaller batteries as well

rudedog

this is pretty much the same thing for a fraction of the price

Not quite, the xpg's do produce more light, it's BECAUSE they're more efficient you can push them further, an r2 at 1a is about 250lm whilst the xpg will be 345@1a.

Your getting muddled with the xpg using the same phosphor as the xre r2.

As for why need such light, true but i like to see everywhere!!

This is the same liberator design but with xre's as the xpg's aren't released until the end of this month, as you will see a trout light is far beyond most lights if not all.

Plus i can have my beam pattern however i want and can change it quite easily, how many lights on the market let you do that, too many out there are concentrated in a small area, that's no good as you end up blinding the riders in front of you remember lumens is total light not how it's spread.

And for £170 for the unit and £115 for a 5.2ah pack and charger i really can't complain.

Are you talking to me? I don't know anything about phosphors etc, but I'm guessing the comment was at me. I know you can't seperate efficiency and output but the point I was making is that the xpgs don't just produce more light- they can be used to produce the same amount of light as a P7 but with lower consumption. To me, that's going to be more useful, since we're already up to **** me that's bright levels. Time to lay off the lumens and work on packaging and practicality IMO. But I doubt that's what'll actually happen mind, since people are drawn to big numbers...

supersonic

I think I might be right in saying the harder you drive the LED, the more efficient it gets (percnetage wise)

Dazzza

Yup plus the xpg actually is more efficient hence it pushes out more at the same amperage, but it was more aimed at 77rlc and his questioning the need for such a light.

For me it's not the total light more the spread, i've seen to many lights that compensate a poor output buy not having a very floody beam, even a lupine betty isn't that floody and it has but a tiny edge over the p7 on it's own hence the picture above just a nice solid wall of light no doughnuts, halos or white spots anywhere and imo a perfect spread of light it just happens to have a high lumen count because of it's spread.

Common misconception is high lumen always equates to a silly light, it all depends on how well the light optics are put together hence my choosing the troutie, that and he puts them together making any upgrades or changes quite easy.

Plus it also means i can run less led's should i wish with the driver that's fitted meaning exceptional run times and still a decent amount of light, this is going to be my bontrager 24/12 light as im a night owl anyway from my ta days.

Hope that explains enough........

Dazzza

And for those that are curious more details on the nuke proof light.

http://s199.photobucket.com/albums/aa46 ... man/BRNTS/

Troutie helped brant perfect this light with things like rubberized cables and different optics, similar to the luu light but better and a bit cheaper at full retail, still pricey but a better alternative.

supersonic

What powepack is the NP using, and drivers? I still doubt it outputs 900lm.

Sorry for just the link, it's late. :oops:

supersonic

CHeers for that.

Looking at the figures of 4 hrs from the 'super mode', it ties in with 4x 18650 cells in parallel. Probably more efficient optics thatn your standard torches, I think you have to say will be around 6-700lm. Just like you said ;-)

LUX rating is interesting, but without area or beam angle is as useful as a candela rating.

Dazzza

Yeah, im glad trout had a hand in it's final design, it shows how much he knows when manufacturers even listen to him, makes me glad im having a light whilst no one has signed him up.

daveplanetx

not sure which pricing youve looked at , but on a like for like basis the luu lights are circa 40% better priced than the nukeproof, plus have the added advantage of you have the option of screw in AA battery case. Theres definitely a bit of misinformation in this thread.

the price differential is simply explained because on-one buy direct from Luu , are their exclusive uk distributor and sell direct and not through retailers

nukeproof have more traditional distribution, they buy from Luu , sell through hotlines , to dealers , and sell on , hence the 40% uplift .

We believe the Luu light is a more versatile light , its definitely better priced by around 30-40% from on-one , most of the light / internals are exactlu the same , as Mr Trout will confirm next week when he gets a light to test. .

bikefish

If you like lights, how about a Deal Extreme P7 like torch then? These can be got for 20 quid each, and just over thirty notes with two cells, charger and bar mounts!

One has to be careful making statements like this without testing the product and seeing what it can do! sureley... We have offered Troutie a Luu LED to have a look at and Dazza seems like you want to see one as well
This may be true on the Chinese P7 torches, but you cannot tar the same

I tested this several months at my old job (lighting). :idea: I ran it in a heat room at 35deg with probes on it. This Luu LED light has some excellent features. I have posted some LED 101 lighting engineering considerations here http://www.on-one-shop.co.uk/?p=3019

900lumens is the LED emitter output so you cannot really say that it is more like 700 without testing. Also it is not really a measurement that you can quantify without a good reflector or optic. Lux and light spread is the measurement that the public need to measure. However I have seen poor optic or reflector design halve the light output from LEDs so this is REALLY more important.

It is also important to have a uniform beam pattern....

Personally i'm just glad we are starting to get decent light set's with good output and good optics designed to do what we want and all at decent prices AT LAST ! No more looking at Lupin light sets ect and thinking ohh how i wish i could spend £600+ on a set of lights for my bike :shock: :roll:

Dazzza

It's not a question of the light itself nor the optics it's the limitation of the emitter itself, most p7 emitters top out at around 6-700 lumens the 900 ssc quote is a theoretical maximum.

Lol i like to see any light in action it's what i do.

When i said it's nothing special i meant more it doesn't bring anything new to the table and choosing aa's for the battery pack is an unusual choice when li-ion handles the current drain far better, then again you might be using li-ion aa's i don't honestly know.

Don't get me wrong it's a nice and at £199 not bad it's when it bumps to £299 then the scale of economy come into play, i know of one light set by a reputed brand, kicks out an actual 1120 lumens which makes it close to double of the p7 and can be had for £349.

The problem with the p7's isn't so much current supplied but thermal they get very hot if left on for a while.

The p7 doesn't lend itself as a spot light as the optics on the die combined with the spread of the die's themselves lends it to be floody by nature.

What would be ideal right is a luu light but instead of a p7 try using 3-4 of the new xpg emitters that are out this month, they have a max rating of 345 lmens, 3 of those in a luu light would knocks spots off the p7 and have a better run time.

It's great seeing all of these lights about but they've come to the party a little late, led's are constantly evolving and it's the guys like the trout that are keeping an eye on what is going on.

stevoisonone

Dazza email me at stevo@on-one.co.uk and we will loan you something..

The LUU does come with a 4CELL Lithium Ion giving 4.5 hours at full punch
The Extra CNC battery allows extra 1.5hours but will run longer on other modes

All LED systems have some kind of compromise
I do think that Luu has brought something to the table. The Multi use aspect allows for both Bar and Helmet mount Narrow / Med / Wide beams...
We are in the twilight of LED technology here.. :shock:

Had mine on for an hour last night and they weren't even warm, sorry but unless a while means all night then you are completely wrong.

Dazzza

Depends on the current being supplied.

I do like how you can change the optics, what would be a nice step up would be to be able to change the optics and the emitter board that way you can keep up with the constant changes.

Thanks for the loan offer it's very nice but im terrible for looking after them. :oops:

Have a nose at this k light, something like this but from luu now that would be interesting with the xpg emitters.

http://www.cutter.com.au/proddetail.php?prod=cut889

Just had a closer look at the luu, it's certainly an interesting concept.

bikefish

Stevo, how much current is being supplied the P7 emitter in your lamps, and what capacity is the battery pack?

Surely the Lux measurements need to take into account the beam angle as, just like a laser, you can calculate some impressively high looking, but useless figure. Also beam pattern as some lux ratings at a specific point will be different if the beam is not uniform.

While this is true of the lumen measurement, at least you get an idea of luminous 'power'. Maybe all the figures need measuring to give a full picture, as one on it's own doesn't.
