Decent mount for seatposts, but $$$$$, ugly, and doesn't work on rear racks.

My favourite combo for super bright taillight is still the same setup I made 3 years ago. Super bright $11 red led flashlight (cost $20 3 years ago) with highly adjustable mount that work on racks, handlebars, and seatposts. The flashlight is secured with a quick release, so it's super easy to take off and put on.

Yes. You can't go wrong once you are set up with the 18650 batteries and charger. My headlight is a Shiningbeam 1 x 18650 flashlight. I also have a cheaper, DealExtreme 1 x 18650 flashlight, and a cheapo DealExtreme 1 x 18650 1 mode red flashlight. I just pulled the trigger on the 5 mode red flashlight listed above. It will replace the Cygolight Hotshot that I lost a month or so ago.
I'm trying to standardize all my lights to use 18650 batteries.

Any opinions on Exposure lights?

fietsbob 12-25-13 04:58 PM

Never heard of them.. till you mentioned it ..

I see it's British.. DIY comparison http://www.use1.com/exposure-lights/lights-comparison

UK stuff is not so easily distributed , we get German stuff because Peter White invested
to be the distributor in North america..

seems from surfing the site, an Off Road , light up the trees and the trail . kind of beam

theres others using that approach too. I expect the CNCwork and Anodizing is fine.

have bought some USE seat post shims , same company.

as far as taillights, this one looks cool http://www.use1.com/exposure-lights/...r-lights/blaze
if you got nothing else on your seatpost.. its U$D 152.

It seems they operate on this side of the pond as well:

http://www.exposurelightsusa.com/ edit... Actually this site looks to be a reseller...?

and Competitive is selling them... I like the form factor, rather compact.

how many hours of blinking do you get on the serfas before needing recharge?

The MagicShine MJ-818 - it's essentially half of a Dinotte 300. Buy two of them and a battery pack (assuming you aren't already running a compatible battery pack) for about $80. It does use a separate battery pack, so it's a little more complicated. If you are running a compatible battery pack already you can power it from a Y cable and buy it with the Y cable for $30. This is a ridiculously good value.

However, assuming you're looking for a stand-alone light:

In the less expensive camp, the Cygolite Hotshot is quite good, though the beam is pretty spotty - max visibility only directly behind you. $28 on Amazon.

The Serfas Shield is VERY good, nice wide pattern, decent side visibility. They've recently dropped the price from about $53 to $39 (on Amazon) so that's probably my choice if I have to choose ONE taillight. BEWARE of the strap clip for that - it's useless. Mine fell off three times on me, the 3rd time I never found the light again.

I have a Knog Blinder 4V, which has the best dispersion I've ever seen (equally as bright from any angle behind you) and is very bright, but the battery in it is very short lived - I have to charge it more frequently than any other light I own. It's nice to keep on the road bike in the summer just in case you get caught out after dark, because it totally blends in with the seat post and weighs little. But I wouldn't buy it as a primary light in the winter when I was using it daily.

Here's a video I shot a while back:
http://youtu.be/12xDjS-ot8w

As you can see, the Serfas is a friggin' blowtorch.

IMO, running two completely independent taillights is an absolute must. If you lose your taillight you're in trouble, and you won't know it's out. I personally usually run three; a Hotshot on my helmet (fast blink), a Magicshine on the rack (steady), and a Knog Blinder 4V on the seat post (fast blink). Even if I had a Dinotte 300, I'd still want a 2nd taillight on at all times.

What is your preferred brand of 18650 battery? Buddy gave me an Ultrafire, and I made a bar mount for it out of old nightsun parts. Its great, but the batteries are crap. One goes dead in 20 minutes, the other was not so bad, but not very good either.
Thinking about getting a couple more, mounting two on the bar. That should be very bright, but need to get better batteries for them.

How old were those batteries your friend gave you? That's what they do when they wear out. I pitch them as soon as they won't hold a charge.
I don't buy any particular brand. All I've ever seen are the blue ones. Seems like I get about 2 years use out of them and I keep about 3 pairs which I rotate.
I know there are cheaper chargers but I sprung for the Pila a few years back and it has performed beautifully.
The nice thing about the 18650's is that there is so much power in a single cell. You don't have to fumble with numerous cells like you do when using AA's. Makes for an easy battery changeout when you are out on a ride on a cold, dark night.

I really don't remember. I don't think I ever tested it. I was using it at the same time as the Knog Blinder 4V and I always take all my lights off at once when charging any of them, because I can't keep straight "OK, I charged the Cygolite on Tuesday, it lasts 6 days, the Knog on Monday, it lasts 3, so I should charge this on October 43rd, carry the 6...."

The Knog has the worst battery life of any light I've owned, I have to charge it twice a week, so everything got charged twice a week.

Anyway, this is from their web page. It doesn't sound wrong to me. Probably the Serfas wouldn't last that much longer than the Knog, I usually ran it on bright flashing.

Run Times: (60 lumens = 2.4 hours; 35 lumens =5 hours; 60 lumens flashing = 4.5 hours; 35 lumens flashing = 14 hours)

UltraFire

The light my friend gave me was new, but bought off of Amazon, don't know if its a knockoff or what. The batteries read ultrafire. Read reviews, and gathered that Chinese manufacturers will take apart lithium ion battery elements that have been "recycled" and reassemble them in new packaging, thus the 10 dollars for a light, two batteries and cheap charger.

Was thinking about getting some other brand that might not be as prone to this, but still not sure. The knockoff lights are fine, but don't want to have to keep changing batteries on the side of the road.

sknhgy 12-26-13 12:17 PM

Most of my night rides last about 90 minutes. I run my Shiningbeam MC-E on medium and it is good for a full ride and more. I'll click to high beam if I need to flash an oncoming vehicle or if I want to look at something off to the side of the road.
I have a $10 DealExtreme flashlight that I converted to run straight off the battery, bypassing the circuitboard. I thought about mounting it on my handlebars to use as a superbrite auxiliary light but I just haven't got around to doing that. That one only gets used for short bursts because of heat and battery drain. I've been using that light for a couple of years and haven't had any problems with it.

I've heard this too, but I've torn apart a few of the UltraFire batteries I've had and have seen no evidence of them being recycled from other purposes.

I'm not saying it couldn't happen, but I do wonder how accurate those reports are. I wonder if they're just guesses that have been elevated into legend by being repeated many times ...

ItsJustMe 12-26-13 02:07 PM

Honestly I don't believe the recycled thing. Sounds to me like a story that people selling high end batteries make up as a FUD campaign against lower cost competitors. I don't think the cost combined with the low yield would be worth it.

Combine that with the fact that if they did this, no two batteries in a purchase would have anything like the same capacity, as some would always be more or less depleted than others, so anything like this would be detected quickly.

I don't remember exact numbers, but I did do a voltmeter test on the two batteries, and they were radically different. Add to that the twenty minutes of life on one, with about thirty five or so on the other. I do know that the charger it came with has a lot of, Ahem, chinglish. I would never leave it unattended, that's for sure.

did some light googling(no pun intended)and found a few threads on various forums on the subject, here's one. http://www.candlepowerforums.com/vb/...attery-warning
Nothing conclusive, but interesting. Post #24 is the most interesting, though he does not cite any proof. I am a believer in not buying the cheapest thing I can find.

Still, I love the light while it shines, and can only imagine having two would be incredible on the front.

On the OP thread topic, I am sort of torn between the PB turbo or the Serfas shield.

ItsJustMe 12-26-13 04:59 PM

I think if there is someone selling "Trustfire" or "Ultrafire" batteries and they're recycled, it's probably a bootleg. I really doubt that the companies that own these brands are doing it.

There is a lot of bootlegging going on in Asia. People get IC chips that are just plastic blobs with wires sticking out, for instance, and they have major name brands stamped on them.

I have a Blinder 4V and I love the light that it produces, but I don't like much else about it. The flip out USB charger is a pain in the rump, I have to unplug other stuff to get it in to my computer. The battery is the shortest lived one of any light that I own, and the mounting really only works for one thing, the seat post. There's no way to use it on any of the normal places I put lights, like on the rack, my helmet, or my bag.

I just relegated it to living on my road bike in the summer in case I get caught out after dark.

It's a Smart V2.0 (1W, or rather, 2x0.5W).

Where do you buy a Smart v2.0? I just searched online and couldn't find anyone selling them. Just a bunch of YouTube videos. The Danger Zone, OTOH, is easy to find almost anywhere.

I found a Smart light that looks like a copy of the Planet Bike Superflash. They even call it the "Smart Superflash"

It looks to me more like they are exactly the same lights, but are being distributed by different companies on different continents.

SmallFront 12-27-13 04:58 PM

It's not a copy of the Planet Bike Superflash. Planet Bike just did the same as Portland "Design" Works: Calling it their own even when it isn't.

The dual light also comes in a headlight, where the lower is a reflector, and the upper, the actual light:

If you do a search on "Smart RL321" (perhaps without the """), you should be able to find the tail light, even on Amazon.com.

Also try searching for "Smart Bike". It may be more widespread in Europe, but Portland "Design" Works are being untruthful when they claim it is theirs, and so is Planet Bike with the Smart Superflash.

It is telling that the Portland Design Works still carries the "Smart" name, so I seriously doubt this is just a question of different distributors. It may very well be that PDW is the distributor of Smart lights, but since they still carry the "Smart" name over there, it seems they are at most the distributor of Smart lights, if you know what I mean.

It's available, with shipping, for 20 euros from the German Amazon. There are several other Smart cycling lights there; several look like a variant branding of what I'm used to seeing from Planet Bike in the US.

It's out of stock in the Canadian Amazon and I don't see the brand on other Amazons.
