sampie Posted May 30, 2008 Posted May 30, 2008 I agree, the sa site have no info on products, the .com one a bit more. Had to surf the web to get some specs and read up on some reviews on this product. Must say, the reviews i read by people using it are quite good. So far i got replies from them within a day of the queries i had. Aren't all stuff 'Made in China?'
WillemT Posted May 30, 2008 Author Posted May 30, 2008 what about rabtron? It's a good option if you're okay with Luxeon's. I spoke to them ALOT aswell. In short, they are not allowed to import other LED brands. A luxeon will give you max 80 lumens per LED and for the same power consumption you can get 200- 250 lumens from a cree Q5... Some of the guys have build some nice lights with the luxeon's, so it's a option. I can get some cheaper LEDs but at the end it's just better buying the good stuff, not the best though cause then you're going to pay alot extra for a small difference. With the LEDs it's all about efficiency, one cree q5 wil cost you not nearly as much as three Luxeon IIIs and it uses a third of the power consumption... and thats what you want, so at the end the older LEDs will be more expensive lumen wise... night tider2008-05-30 03:47:50
Marius Posted May 30, 2008 Posted May 30, 2008 Sweet, please get the good stuff for us Nt and don?t compromise.<?: prefix = o ns = "urn:schemas-microsoft-com:office:office" />
WillemT Posted May 30, 2008 Author Posted May 30, 2008 oh no!!!!! all stuff are not made in china. My dad and his business partner import all their stuff from the USA and none of it is made in china. They want to switch to some taiwanese PICs but not chinese. Somebody PMed me and asked about drivers.In short, i'm thinking of using normal luxdrive buckpucks, they're simple and works good, there's also some other drivers that I will look at but they're about three time's the price or more, there is some really nice ones though!! And they're step up drivers wich opens some very nice battery options! Will defenitly get at least one of them for an option.
WillemT Posted May 30, 2008 Author Posted May 30, 2008 where can you get cree q5s? Well you've just managed to describe my whole mission, to get cree Q5's, affordable, genuine and a reliable supplier. So as soos as I got that figured out i'll give you more info... Still waiting from a few suppliers to reply from USA, europe, and australia... I'm going to try and get them straight from the factory, that in it's turn will be a little complicated because you have to be a company that manufacture electronics as far as I know. Have a few contacts so i'll see what I can do...oooo wil be so nice if I can get that done!!!!

[/quote'] Keep up the good work night tider and please keep us up to date with your efforts.My research showed the same as yours, so I just settled for the Luxeons to get a light built.I plan to build a second light and if I can get some Cree Q5's it will be great! If only I could have the time available you have as a student.... enjoy!
Captain Fastbastard Mayhem Posted May 30, 2008 Posted May 30, 2008 Howzit guys - just gone to the DEALEXTREME site - still coming out good for prices etc. Went to their contact us section, and - guess what... They're based in.... that't right. HONKEY KONG! Night tider, if u can get Cree q5's cheaper than from then, I'll come in with you to get some as well for myslelf, as well as some reflectors/lenses. Good luck with the exam!
WillemT Posted May 30, 2008 Author Posted May 30, 2008 Love being a student!!! Still lives at home, wich not always nice but has some huge advantages!!! Ok so I put together a few ideas, really just had 30 mins so it's done very rough, just the idea... When I have some time on my hands i'll make nice a nice detailed design... Anyway basic I have two ideas for housings. The one you see below is just a normal alluminium tube. It will get a glass cover in the front. At the rear you can put a grommet for the wire or maybe a pannel mount DC socket where you see the whole, you can put flip switches in the back just like the grander housing. The idea for mounting on this is a hole drilled in the bottom(not in the pic), the screw that goes in there will be screwing into the back plate behind the LEDs, tha cover plate at the back will be connected to the LED backplate with stack screws working as spacers. So basicly the screw in the bottom will hold the whole assembly together. If you take out that screw the internals can be pulled out the back. The better housing of the two has a taperred inside (right where you see the "fins" on the outside) where the LED mounting plate (approx 5mm thick) contact the housing and the heatsink is integratet with the housing as you can see. In 2 of the pics you'll be able to see a flat part on the outside meant for mounting. This housing will have to get a screw on lid or something on the front wich will hold the LEDs and somthing simmilar at the back. This is just a shape idea that in did in 10 mins so it doesn't have the detail of the design yet. I will find out next week more or less what the manufacturing costs will be of a housing like this one. Bottom view:bottom side view: Side view: The three pins sticking out is where i'll put my toggle switches.I'm going to go with 3 toggle swichtes wich will give you on, of, dimm, bright, 4 Leds, 2 LEDs (with the 3 LED light you'll just have 1 2 or 3). So this is more or less my two ideas in development... night tider2008-05-30 11:58:35
WillemT Posted May 30, 2008 Author Posted May 30, 2008 both housings can take either three of four LEDsWill make a muck simpler and smaller one to take 1 LED
mountain_lion Posted May 30, 2008 Posted May 30, 2008 I don't understand your mounting system.Mounting the housing onto a handlebar and/or helmet is the most complicated part of a bike light.You want something that is easy and fast to mount and remove, but is still secure on rough terrain. mountain_lion2008-05-30 12:09:02
The Saint Posted May 30, 2008 Posted May 30, 2008 Nevermind I can answer my own question as it seems like I am talking to myself tonight. 500 Lumens will equate to 39.77 candlepower. Not very bright. I ride with 2500 candle power and that is still not good enough.
WillemT Posted May 30, 2008 Author Posted May 30, 2008 i'll quickly you post a photo of the mount I have in mind.
WillemT Posted May 30, 2008 Author Posted May 30, 2008 this a mount of a cateye. I'm looking for a mount like this. I know you can buy the bottom part of this at the LBS, but not the top part. You'll see the screw standing out, that's where i want to mount the light.
