10 Wheels

This should be a much better test. 6:00 PM 2-7-09

Control: Toyota 2002 :PBSF on Trunk Left Side:
Dinotte on Trunk Right Side

Added Bicycle Front Lights to contrast as in traffic.

I had just returned at 6 PM from a 100 mile ride

Wow that is a fantastic daytime light. I'm wondering if it is overkill at night, and you just convinced me the 140L is King of daytime riding.

Siu Blue Wind

Wow. That IS pretty bright. Thanks. The vid really helps.

i've been trying to tell everyone....

Thanks a lot for the demo.

I wouldnt mind having a Dinotte but not the cost. Interesting note on your video- The PB looks way brighter in Steady mode. Maybe PB should rethink the speed of their strobe and make the "on" a little longer.

The PBSF is Brighter on Steady.

My goal was to present a Fair Test.
I came close using the car for a control.

The Dinotte Remains Bright from a very long distance while the PBSF will soon disappear from site.
My camera was on an auto setting so made some adjustments to the lights.

One has to see a Dinotte in the Real to fully appreciate how bright is is.

CastIron

^^ Absolutely. I've seen both in many traffic situations and the PBSF is great in the dark. The DiNotte is just plain magnificent. No qualifiers needed.

Its nice when purchase something and you feel it doesn't cost much, I get that. But tail lights are all about personal safety. Any cost analysis goes out the window for me when it comes to personal safety. My next of kin won't appreciate how frugal I was being.

Looks like the PBSF on Steady is about as bright as the Dinotte on Low - not bad for a little $20 bugger.

KungPaoSchwinn

I myself was holding back from buying one because my bike costed only $165,added helmet and other cheap needed things and they costed almost as much as the bike,i just bought the Dinotte 140 L last month and it's bright even under direct sunlight, not sure if the PBSF can perform under such condition,money well spent on the Dinotte, good service support is a bonus.

Actually, this great video is convincing me that my PBSF is more than enough! The Dinotte is kick-butt no doubt, but I think the brightness of the PBSF is more than adequate.

The thing I like about this test video is that its done from the distance a driver would need to identify a bicyclist if they were coming up on one at speed and needed time to alter their course enough to give the rider some space. At 45mph a car is on a rider from that distance in seconds. So many people judge their tail lights from two or three feet which is a worthless test.

Also keep in mind that this test was done in clear conditions, not rain or fog, so if you think the PBSF is adequate in this test you have to ask yourself would it be in the rain or fog?

10wheels,

Awesome video. I thought you;re coming into the video in your birthday suit for a moment there. O_o;; LOL. I'm so saving this video to the ipod itouch to show other riders along the way so they can see from a distance. Sometimes people have to see it to understand it.

I Moved away from the BPSF because it continuously fails in rain - water get inside and soaks the switch, the light goes dark.

Am now very pleased with a homebrew solution, shown below in comparison to a PBSF. Never had the opportunity to directly compare it to a Dinotte, but I estimate my light is better visible for drivers that are not directly behind my bike.

I moved back to the PBSF from my Dinotte now that it is much lighter when I leave work, making the PBSF sufficient enough to get motorists' attention when used in conjunction with my Serfas TL2000 tail light. Plus I wanted to reduce the cost of my lighting system in case of theft since I realistically only need my high powered lighting system 3 months out of the year.

Being that the PBSF light has a very focused beam, viewing your photo, looks like the PBSF would be better suited on a more rigid surface such as on the rack so that it is not pointing downward as shown.

Another video, showing the 140L and PBSF at twilight, along with bar-tip blinkies:


The PBSF (mounted on the rear rack) basically vanishes in the wake of the 140L. If you mix it up with fast traffic, the DiNotte's much harder to overlook, especially if you want advance detection in daylight.


Static shots showing the NiteRider Cherry Bomb, which is on par with the PBSF, compared to a DiNotte 140L.


Cherry Bomb on steady-burn. The PBSF is similar in overall power.

I bought my Dinotte 140L after thinking about what the PBSF would look like in fog.

I used to run an amber strobe in the back; I don't even really think the Dinotte 140L is quite enough for heavy fog. It would be if people drove sanely, but once in a while you get the moron doing 50 with 10 feet of visibility.

An amber arc light won't save you from the idiots.

davidad

I have been behind Fred's, Sharon's and Doug's Dinottes in the day time and night. Nothing comes close. A car's brake lights are not as bright.
At night the 140 is too bright to ride behind unless it's pointed down slightly.

ItsJustMe

No, but from experience I know that if I'm lighting up the entire fog bank with a strobe light, drivers slow down. I've seen it happen - OK, I've HEARD it happen, as they approach from behind and get within about 100 feet where they can see something strobing ahead - amber strobes make people think of road service trucks or emergency vehicles or cops or something else they don't want to hit, and I hear them slow down.

Incredible lighting demo. I couldn't stop laughing at the black knee high socks that guy was wearing.

what do you have against black?
