Light 'em up boys (and girls)

Postby Uba Tracker » Sat Jun 28, 2008 11:27 am

Well given the lack of daylight hours we are currently languishing in I figured it might be timely to discuss lights. My personal experience saw me buying a collection of of headlights in the hope of spending a little and getting alot. I knew in the back of my mind I was kidding myself but I couldn't help it, after four different lights in as many years I finally caved in and bought a decent light, a NiteRider MiNewt. What a fantastic little unit, 3.5 hours(ish) on high beam, 7 hours on low and about 21 hours on flash. It uses ultra bright LED technology up front and Lithium Ion batts in the engine room. I paid $350 for it from my local bike shop but I have seen them a bit cheaper on-line, I had the 'Kid in the lolly shop,' head on that particular day so there was no waiting for one. Other riders have commented on how bright it is, one chappy was coming towards me probably three k's away, when we finally met up he stopped me just to check out the light, he noted that the further away I was the brighter it appeared. I like how compact it is and how simple the fit up was.

This is my homebrew light...

Image

Image

Image

Image

3 x Cree XR-E 3 watt LED's driven with a 1 amp current limiter circuit, but clamped to 670mA (2 watts per LED).

The light put out 480 lumens, with about 8% loss through the optics. The optics are 2 x 9 degree collimators, on the outsides, and one 15 degree in the middle. I have a few side-by-side comparison shots around here somewhere, taken at night against a 12v 20 watt halogen overvolted to at 14v, and this light is a bit brighter. It can be dialed up a further 120 lumens (at a cost in runtime), to be as bright as a 30 watt halogen.

It's powered by a 2200mAh Lithium-ion polymer battery, good for about 3 1/2 hours runtime. The battery weighs 190 grams, I haven't weighed the head or circuit but I would guess maybe 100 grams.

It's temporarily mounted on the stem from my upright bike untill I work out a more permanent (cleaner) mounting solution. This was just the quickest & easiest way to move it over to the 'bent.

Hi Matt,
Yes, these lights are seriously bright. The rear red light can be seen in bright day light too. Riding in the dark, I set the rear light pointed slightly downward to cast a red light on the road as pointing directly to motorist is rude and can be blinding.

Leigh, I love riding after dark or before sun up, there's something really gratifying about carving up the darkness on a lonely road and looking skyward to see countless stars. It's a bit harder to find the enthusiasm on these cooler mornings but it's so worth it once you're out there.

cheers

Glad I'm not the only "Night Rider"

LED lights are just tops. I have two yes 2 Dinotte rear red lights one pointing to the road the other pointing level back one steady the other flashing. I was told by the local police that I looked like an ambulance going down the road. I also have two, yes 2 Dinotte 200 lumen lights pointing forward. One on my handle bars and one on my helmet. This is all mostly for the CRAZY drivers here in El Paso TX. Yes, it's a cool thing riding at 4AM in the morning climbing the steep hills here and ripping down them with a spectacular view of the west desert near sunrise. Our lows are near 34 and highs near 44 this time of year. Thanks for science inventing the rechargable battery! - Just ride -Rod

That is a really nice looking bike, I really like the yellow/black combo.

Do you have more details of the rear wheel covers? more detail photos?....and what is that front wheel?

Hi Cyclaholic,

I promise I'll answer all your questions about the wheel covers this week - I'll start a thread about them.

The wheels are Velocity Deep-Vs as shown in this thread.

Cheers,
Graeme

Slightly off-topic, but how does one attaches a handle-bar mounted headlight onto a the front-derailleur post of a 'bent? I have seen a commercially available bracket that has a tube the same as a standard handle bar but I can't remember the brand name.

My new Toscana 2026 USS from Just Bents arrives next week!

thanks,
Jeremy

G'day Jeremy,

Take a look at Cyclaholic's first photo in this thread. You can see he has mounted a normal handlebar stem to his der post. Just get a small length of 1" tube from Bunnings and mount it in the stem, then mount your lights on that.

Cheers,
Graeme

... so I can post this photo of the boom and front derailleur post

... that seems to be sealed. How am I meant to put a handlebar stem into it?
Cyclaholic, did your derailleur post come sealed like this or did you modify yours?

A threadless stem should see you right froodh. They wrap around the pillar.
This pic...

of Cyclaholics setup shows the pinch bolts at the back of the stem.

You need a threadless type then it can clamp over the derailleur post.

I have one here but that,s not much good for you :(

Ahh, OK. Understand now. I was thinking of the old quill-stem headsets - shows how old all my other bikes are!

Thanks guys.

I was tempted by the MiNewt X2 for $174 US at Amazon a few days ago, but thought I'd a wait a little longer for them to come down even more. Checked back yesterday and they'd gone down to $49 US!!!! Needless to say I have ordered one and it's on it's way.
