For a long time, no there was no work on internal battery lights, for me. The design you refer to was book-shelved, but I could revive it. I'd need to look into that particular design, again. Other than that, I can't say anyting just yet (its difficult, must resist), but hopefully, soon I might be starting my own light thread... In addition to just chatting about lights, when the opportunity arises Cheers <img src="http://singletrackworld.com/forum/my-plugins/bbcode-buttons/default/icon_wink.gif" title=";-)" class="bb_smilies" alt=""/> wors on "Luu 900 lm bike light (on-one)" http://singletrackworld.com/forum/topic/luu-900-lm-bike-light-on-one/page/2#post-1738338 Tue, 24 Aug 2010 11:43:55 +0000 wors 1738338@http://singletrackworld.com/forum/ Are you still working on that self contained unit then?

Its been computer simulated and tested, also having a thermal cut-out to prevent damaging the internals. CNC Ali housing produced by one the best Machining companies in the UK. They do Aero, Auto and motor race stuff, as well as specialist tooling and the machining of special materials, and petro-chem stuff too. As far as machining Companies go, they're 1st class. I'm not big business for them, I think they do my work just to help out. I like them because of the quality of their work, but also cos I'm giving work to a UK company. It helps also that the guy I deal with there is an ex-team rider, darkside, and has a genuine interest, so he makes a real good job of the CNC work, getting stuff to with very fine tolerances, including some detailed features. Most companies really wrag their machines to get machining time for an item, as short as possible, which has an effect on final overall fit and finish. For larger numbers, L&M and Lupine use castings, with which there are both pros and cons. <img src="http://singletrackworld.com/forum/my-plugins/bbcode-buttons/default/icon_wink.gif" title=";-)" class="bb_smilies" alt=""/> pabsw1982 on "Luu 900 lm bike light (on-one)" http://singletrackworld.com/forum/topic/luu-900-lm-bike-light-on-one/page/2#post-1738243 Tue, 24 Aug 2010 11:18:44 +0000 pabsw1982 1738243@http://singletrackworld.com/forum/ Yeah I see that. Absolutely. there's always a trade-off for something. for me durability, quick recharge and reliable run times are key. In the L&M I've found these things plus a light that's powerful enough for my commute and occasional trail night ride. I carry a small BLT backup light but that's it and the roads ain't lit here on my commute. so yep I'm happy with it for now - but of course, you see something newer and better and you immediately reach into your pockets to find.... some lint and a couple of pennies. so is the barrel length on your 601 mainly the heatsink? I must say it looks like good workmanship - do you CNC your own aluminium parts for it?

More like a Web-page, it could be better. <img src="http://singletrackworld.com/forum/my-plugins/bbcode-buttons/default/icon_redface.gif" title=":oops:" class="bb_smilies" alt=""/> Could use some help with that, if anyone's interested. No, the Model 601 light you see, uses an external battery, theres two configurations now, the 601, and for this season there will be the 601 Enduro. The Enduro doesn't quite match the 601 on output, but has longer runtime Lights with batteries inside....hhmmmmmmm <img src="http://singletrackworld.com/forum/my-plugins/bbcode-buttons/default/icon_wink.gif" title=":wink:" class="bb_smilies" alt=""/> I remember having a chat with an Autocar Journo years ago, one of the first things he said was "theres no such thing as the perfect car". Perhaps something similar could be said about night riding lights, hence the choice and the variation on the theme. This thread started with someone reporting about a light they were disappointed with. It would seem that there are still some shonky lights out there. The guy I know with the LUU light says its too dim and too heavy for realistic helmet mount in his opinion, so hes looking for something else for this winter. It would seem that the light you have now is much better put together than your previous light, allowing you to use it as intended. I think the smartest cookies are commuters who buy a good spec front light, then use it, double-duty, for the commute and for the night rides. <img src="http://singletrackworld.com/forum/my-plugins/bbcode-buttons/default/icon_smile.gif" title=":-)" class="bb_smilies" alt=""/> pabsw1982 on "Luu 900 lm bike light (on-one)" http://singletrackworld.com/forum/topic/luu-900-lm-bike-light-on-one/page/2#post-1738117 Tue, 24 Aug 2010 10:48:30 +0000 pabsw1982 1738117@http://singletrackworld.com/forum/ oh and regarding the battery - I've been using it to commute for 2 years now and seen no discernable fall-off in the battery longevity. I think they use some kind of special charger which caps the charge when the battery is a certain amount full then enters a kind of hibernation mode. just as well when a replacement battery is so costly! pabsw1982 on "Luu 900 lm bike light (on-one)" http://singletrackworld.com/forum/topic/luu-900-lm-bike-light-on-one/page/2#post-1738090 Tue, 24 Aug 2010 10:42:44 +0000 pabsw1982 1738090@http://singletrackworld.com/forum/ yeah HID is still way beyond LED's in terms of intensity but there's the cost of the bulb and the energy issue I believe. I should point out that I am not a light guru at this point however <img src="http://singletrackworld.com/forum/my-plugins/bbcode-buttons/default/icon_smile.gif" title=":)" class="bb_smilies" alt=""/> I had a look on your website luminous, they look nice. are they integrated units like exposure lights? Luminous on "Luu 900 lm bike light (on-one)" http://singletrackworld.com/forum/topic/luu-900-lm-bike-light-on-one/page/2#post-1738054 Tue, 24 Aug 2010 10:31:56 +0000 Luminous 1738054@http://singletrackworld.com/forum/ Yeah, I make lights, by hand, which I would hope gives me a little bit of a handle on whats out there and on offer. Theres a price point for all who are seeking night riding lights, and for some, that leads to price per lumen assessments, etc. 2.5 hours to charge a 5.2Ah battery still seems a bit rapid, but I guess L&M aren't too concerned as batteries are consumables anyway.

I'm glad you're happy with your seca 700 <img src="http://singletrackworld.com/forum/my-plugins/bbcode-buttons/default/icon_smile.gif" title=":-)" class="bb_smilies" alt=""/> What other lights have been measured and quote Lux ? Well, theres my light, and theres the Busch & muller Big Bang. 70 lux, at 10 metres, 140 Lux at 10 metres, respectively. I think CRC had a lux rating in the sales blurb for the Nuke-Proof light, but with a figure of 310,000 lux, I suspect "fat fingers" may have been at work there, and you need a distance value to go with your lux value. However, the Big-Bang is a massively expensive light, but monster bright too. Probably the best of the HiD lights. <img src="http://singletrackworld.com/forum/my-plugins/bbcode-buttons/default/icon_smile.gif" title=":-)" class="bb_smilies" alt=""/> pabsw1982 on "Luu 900 lm bike light (on-one)" http://singletrackworld.com/forum/topic/luu-900-lm-bike-light-on-one/page/2#post-1737976 Tue, 24 Aug 2010 10:09:50 +0000 pabsw1982 1737976@http://singletrackworld.com/forum/ as I said it's not all about lumens, it's about the quality of the reflectors and the lens too for throw and spread on the trail. plus the battery and the workmanship. EDIT - as I also said as I use the light I don't run it completely down therefore it fully recharges in 2hrs for me and the manufacturers charge from empty is 2.5hrs using multicell li-ion. Look it up. plus you make your own lights so you might possibly be a little bias <img src="http://singletrackworld.com/forum/my-plugins/bbcode-buttons/default/icon_smile.gif" title=":)" class="bb_smilies" alt=""/> Luminous on "Luu 900 lm bike light (on-one)" http://singletrackworld.com/forum/topic/luu-900-lm-bike-light-on-one/page/2#post-1737951 Tue, 24 Aug 2010 10:04:40 +0000 Luminous 1737951@http://singletrackworld.com/forum/ Still not the best light you can get for £250 - £300, esp on the lumen count. Although I prefer Lux, and have my lights independantly lab measured. But way more useable than those LUU lights, imo. EDIT: Charging a 5.2Ah battery in less than 2 hrs ?, thats some charge rate. I wonder what the Battery Gurus say about that. pabsw1982 on "Luu 900 lm bike light (on-one)" http://singletrackworld.com/forum/topic/luu-900-lm-bike-light-on-one/page/2#post-1737828 Tue, 24 Aug 2010 09:33:41 +0000 pabsw1982 1737828@http://singletrackworld.com/forum/ was trawling through the posts and I KNOW this is old but I figured that winter is a breath away now so.. I haven't tried the LUU, but, I did try a 800 lumen light before from the australian company niterider, the photon max. the battery button dissappeared into the battery housing after 2 rides and the light output was pretty good compared to my old cateye ABS 25's, BUT... then I sent it back for a refund and worked a deal on a light and motion seca race 700. despite this being theoretically lower output it is much much much brighter with greater trail visibility as well. L&M claim to be the only company that actually tests their lumen output as you would experience as a user. I have to say that everything about it is kick ass. they are also massively reduced now - you can get up to 38% off in some places - due to them releasing a new 1400 lumen beast! the 1400 lumen one would be too bright for me, but the seca race imho is a great light for the money and goes to show that actual 'claimed' lumen output is not everything, you must consider the quality of the lenses too. the custom lenses do half the work, the LED output the other half. so you buy a powerful LED with a crappy lens and you will be dissappointed if you compare it with a quality lens. plus the whole thing rechaerges in less than two hours with the way I use it for my commutes.

Once I'd figured to bring the aim back a bit, using a narrow beam, them I was more than happy with what it can do. It's not quite as good as the Nightmare's flood and distance compromise, but it good enough robgarrioch on "Luu 900 lm bike light (on-one)" http://singletrackworld.com/forum/topic/luu-900-lm-bike-light-on-one#post-885311 Thu, 26 Nov 2009 09:10:57 +0000 robgarrioch 885311@http://singletrackworld.com/forum/ Finally tried out my LUU light last night, with a lap of Glentress red. IMO the light is great - believe I used the 'spot' lens, on 'medium' power 80% of the time, & didn't want for any more. In conjunction with my Fenix torch strapped to the helmet, felt quite happy. Granted, GT is a fairly tunnel-like experience, but I'd expected major disappointment after the comments above, so pleasantly surprised that it's actually fine. Bigger thumbs-up to the bar-mount, after an early tighten it stayed rock-solid despite many rough landings & 1 slip-off. Provided reliability is ok (we'll see), I now wouldn't hesitate to recommend the LUU, whether or not it is 900Ln. Now, to get on with some night-riding without worrying about how dark it is! <img src="http://singletrackworld.com/forum/my-plugins/bbcode-buttons/default/icon_smile.gif" title=":-)" class="bb_smilies" alt=""/> CountZero on "Luu 900 lm bike light (on-one)" http://singletrackworld.com/forum/topic/luu-900-lm-bike-light-on-one#post-868753 Fri, 20 Nov 2009 17:37:00 +0000 CountZero 868753@http://singletrackworld.com/forum/ When the LUU was first advertised I thought people might be a bit surprised when they got them, and posted as much. The P7 emitter is around 700Ln, exactly the same as the DX Bike light, and the On-One AirBike light, and some DX torches that people use as headlights. I bought an AirBike, and was a bit disappointed with it, as it was very 'floody'. I got a DX last winter, and I was blown away by the quality for the cost. Much tighter beam, decent build, easy to mount. Excellent little light. I really think the LUU is a bit overpriced for what you get, but there are a lot of lights using the P7 now, and most are fairly pricy, so look carefully before buying to avoid disappointment. thisisnotaspoon on "Luu 900 lm bike light (on-one)" http://singletrackworld.com/forum/topic/luu-900-lm-bike-light-on-one#post-868341 Fri, 20 Nov 2009 15:32:55 +0000 thisisnotaspoon 868341@http://singletrackworld.com/forum/ lumens are like watts for light bulbs, i.e. they measure the ammount of light energy emitted form an emitter. Efficiency can be measured in lumens per Watt (arround about 250 for good LED's) lux is the measure of brightness hence the name, "luminous flux", also conveniently the latin for light, and can be thought of as lumens per area. So yes 2 360lumen emitters make 720lumen, but it might not appear any brighter as the human eye just constricts the iris to let less light in. The only way to realy compare two lights is to set them up in a room then produce a radar plot showing luminous intensity Vs angle. dss1234 on "Luu 900 lm bike light (on-one)" http://singletrackworld.com/forum/topic/luu-900-lm-bike-light-on-one#post-868224 Fri, 20 Nov 2009 15:06:03 +0000 dss1234 868224@http://singletrackworld.com/forum/ Just thought I'd give you guys an update. Decided to send my Luu light back to Planet-X. Just to re-assure anybody that has bought or plan's to buy a Luu, it's certainly a nice light - good quality and great burn time. I would stand by my impression that it's not really putting out 900 lumens though, but then I then I think it seems pretty clear that the Soeul P7 is never actually going to do that in the real world. In essence, I think my expectations were a little on the high side. So, nice light, good quality - probably plenty bright enough for most situations, but PX offered me a refund so I thought I'd go for that, save a few more quid and get some Ay-ups.

The quality of the lens and what they do with the light is so much more important (within reason of course). Of all the lights i have seen i really liked the ay ups a mate had. It was the fact that you could use all the output from them and direct them exactly where needed.
