if it's brighter than a dinotte tail light, it might be a good thing that there's no strobe or flash mode.
anyone who's been behind a dinotte tail light can attest to that.

solid/steady on will give drivers a better perception of how fast they are gaining on you compared to a blinking light source. one reason why I like to use 2 rear blinkies with one on flash and one set to steady.

I wish it came in a smaller packaged, it's not exactly 'small' at 30 x 132mm. For size comparison a TR-801 is only 24 x 114mm
I'm trying to work out in my head how to mount it to the rear at the proper angle, aside from mounting it on the helmet without using a rack.

IIRC the DiNotte is 140 lumens, which is well more than the flashlight.

FWIW, I use flashlights for my front lighting and couldn't be happier with them, but I just don't see this as being a good taillight due to runtime, mounting issues, and lack of a strobe or flash mode. Hopefully someone will come out with a self contained light to rival the DiNotte....

Luxeon list 3 Red K2's

LXK2-PD12-Q00 60 Lumens
LXK2-PD12-R00 75 Lumens
LXK2-PD12-S00 100 Lumens

All at 700 mA

good info.

I don't mean to hijack, but I've managed to find a green version of the red: https://www.dealextreme.com/details.dx/sku.20331

comes in blue and violet as well, but I don't see those being too useful.

how is green for a visability/be seen light?

The green would be good for the right side on a boat.

Only doctors and ambulances are allowed to use green over here.

would have loved to see an amber light, but green is the next best thing.
you can't use blue, but green is allowed here.

Runtime is unconfirmed as yet.

I'll mount to the seatpost with a Fenix mount I already have.

Lack of strobe is a complete non-issue as I already have lots of blinkies and it's a legal requirement to have a fixed light here (it's actually more complicated than that a single rear blinky can meet the requirement, provided that it hasn't got a steady mode and meets the required standard -having looked I don't think one exists).

Erm...this is a self contained light to rival the dinotte.

Runtime tests to follow.......

How can it rival a Dinotte when it lacks the basic features of the Dinotte?

Mine was shipped on 3/7, so, Unknown, I may beat you to the initial tests.

I think this may be a super cheap option to a DiNotte with a little modification (new driver with modes). The form factor is large enough to accommodate modification.

Only question is how well it puts out light behind the bike.

I, like Unknown, have flashy/blinky rear lights. This would be great steady. And simple math reveals the runtime SHOULD be well over an hour.

Waiting patiently,

One man's 'basic features' are another man's 'annoying never to be used options'.

Mine still hasn't shipped.

However they have shipped the lens I later ordered.

From the few light studies I have read at work, green was rated as one of the most visible color lights, then blue.

The reason green is not used on emergency vehicles is that green means go to motorist.

Funny you mention, because I heard (dont remember where) that a red light is purposely designed to be much more visible than a green because it's more important.

Help me out here, I've looked on the dinotte site, which rear light are you talking about ?

on a secondary research it seems I can't use green (or maybe just a strobing green) since it's for volunteer firefighters and volunteer EMS.
oh well, if DX only stocked amber.

Seeing as they have red and green it's possible they will stock amber eventually

I'm not sure you are allowed amber over here, I think it's only allowed for turn signals.

You could always fit an amber LED ?

EDIT: thinking about it, breakdown trucks and road gritters have amber lights

amber can be used for many things here, exceptionally slow moving vehicle for one.

Here's the spec sheet for the 140L. Strange that it's actually 120 lumens according to their spec sheet. Why not call it the 120L? Does the 140 signify something else?

I made a taillight using two Lux I emitters running at 30 lumens each at a relatively wide angle, roughly +/- 30 degrees, and it was close to being too bright. I dialed them down to 15 lumens each, added two more emitters, and now it's perfect. I can't imagine how blinding this torch will be. I'm sure you'll have to point it downward.

I did wonder how they managed to get 140 lumens from a single red LED

Actually, a Lux III can be run up to 1.4 A and gives 140 lumens for red and 190 lumens for red-orange.

I picture attaching this to my back rack and angling it down, so it casts a large red area on the ground behind me.

At least that's what I see (hope) in my minds eye. I will post picture as soon as it arrives. Nothing in the mail today....

That's going to be producing a lot of heat and efficency will be down.

Is that the LED dinotte use ?

anyone come up with a 'creative' way to mount these to the rear?
I've only figured out how to do it with my folder, using a minoura space/swing grip, but I can't use the same solution with my other bikes because it's blocked by a saddle bag.

I had thoughts about using a lock block into the velcro straps on the saddle bag, but it didn't work out too well. There's a possiblity of mounting it to the chainstay, but it's lower than ideal. So, aside from mounting it to a rear rack, I'm out of ideas, so I will think up of some more ways to mount it to the rear.
