Well I am actually about 11 months into use of a dual 600L and 140L rear light combo. I first bought a single 600L and the rear 140L, but I felt like I needed a bit more front light, so I got the extra 600L kit.

REAR 140L REVIEW:

This has worked flawlessly from day one with one minor exception (see below). The light is intensely bright and can be seen very very well from nearly a mile back. I have gotten tons of complements from other riders that have seen me using them. 3 other people I know have either gotten them or are in the process of getting them. The mount works very well with the O-ring, and stays in place. The cord is long enough. The cord to battery connection is very good and very water protecting too. The battery lasts more than plenty on flash mode. It charges like it did on day one too.

The only gripe I have with it so far is that the pad under the mount and under battery is rather thin and wears out over time very easily. I have a carbon bike and the site where the light mount goes and where the battery sits have already scratched the paint significantly over the last 7 months. I would suggest doubling up the padding at least!!

600L REVIEW:

Since I have 2 different sets, each came with a charger and 2 of the 4 cell lithium batteries. So, 2 total chargers and 4 total batteries. The instructions for them were rather generic to all the different lights they sell, which may or may not apply to some of these. I would suggest model specific and better instructions. However, the things I really needed to know were clear:

1. Each light with a single 4 cell battery should last 3.5 hr on high mode.
2. Press the button on my left when looking at the back of the lights to start on high mode.
3. At about 3 hr of high intensity use, the left button will turn red and the light will flash warning that there is about 30 min. or so left of battery life.
4. Each battery is good for at least 500 charges.

I specifically went with DiNotte because of the battery life. My night rides last about 2 hr and 15 min. or so, but I wanted a battery life of at least 3 hr incase of mechanical failures or if I decided to extend my ride to about 3 hr or so. Given those requirements, these lights fit the bill perfectly.

Intensity:

For me personally, the single light was probably on the borderline of enough. Hence, the reason I got an extra one. The combination of both of the 600L on the front is perfect enough for me. One I point a bit closer to the front wheel and the other I focus a bit further up the road than the first one. The combo works perfect for me. Also, I do like the white nature of the lights. It did take a couple of rides for my eyes to get used to at the beginning. The light engines themselves don't get hot, which is a plus.

Clamping/mounting:

This was easy enough. The little rubber inserts used for the clamping brackets DO NOT glue themselves well to the brackets, and as a consequence I have lost them already. I hardly ever take off the mounting brackets though, and I do have carbon bars. They have not come loose, and easily maintain their position once in place. They also swivel up and down and sideways, which is a plus for initial adjustments.

Battery life:

This is where the bulk of my complains and dissatisfaction with this product has come from. My lights started to flicker and warm me of low battery at about 3-4 months into it, which progressively got worse to the point that it was happening at the 1 hr mark. Now, let me remind you I only use the lights 3-4 times per week at most, and since I have 2 sets of 2 batteries each, I alternate the batteries in use. So, at the 10 months mark, you can say each set of 2 batteries have been used the equivalent of 5 months at 3-4 times per week.

Problems:

A. One of my light engines seemed dimmer than the other from the get go. Since I was using them both combined, I never gave it too much thought to sending it back for repair/replacement. However, when it seemed that I was sending something in (read below), I took the chance to send it in for repair. They sent me a new one in its place at no cost to me. Actually, they sent me a loaner in the meantime due to miscommunication.

B. Given the issues with my batteries, They instructed me to send in the one light for repair and 3 of my batteries. The other I could keep in the meantime to continue to use while they send me new batteries. They did send me 4 new batteries and later instructed me to simply dispose of the last old battery. They also sent me 2 new chargers and had me send back the old ones. They suggested maybe they were bad and causing the battery problems.

Now, I have 4 new batteries, and original 600L light engine, and the new 600L light engine.

Ongoing problems:

The new batteries are warning at the 1hr and 45 min run time after a full charge overnight! I contacted them pretty frustrated about it and they said "it may take several charges for a full charge to set in". They also said the warning light may not mean that it only has 30 min, but it may have 2 hr of battery life left.:twitchy: Well, what good is that "warning" for if I have no idea how much life I have left??:mad:

Communication/customer service:

Needless to say, so far they have backed their product. Their communication was extremely poor though as in the process of all this I got about 7 different set of instructions on what to send back, what they will send, what they will do, what I should do, etc. Ultimately, we got on the same page despite emails and phone calls.

I am giving these new batteries a try for another week. So far, I am pretty disappointed. Do they get me through my 2 hr of riding in the dark? Sure they do, but I should not be happy of getting 2/3 of what I bought.:notamused:

Light? Very good
Battery life? Suck!!

Are you using these lights to commute? Are they left outside during the summer or in a very high temperature area? I do not know anything about the manufacture of batteries, but the Li-ion batteries begin losing capacity from the moment they leave the factory. This loss is a function of time, temperature, and the percentage charge capacity during storage. Ideally you would store a battery at a 50% capacity in the refrigerator and virtually no capacity would be loss, say a couple of % per year. Stored at 100 degrees Fahrenheit on a full charge a permanent capacity loss of up to 40% could be lost in a year, if my memory serves me correctly. Practically speaking the life of a li-ion battery is 2-3 years.

This is a great source for battery information.
http://batteryuniversity.com/index.htm

This is the section on how to prolong lithium ion battery life. Give it a read and see if there is anything significant that may be causing your shortened life and give us a report if you don't mind. I meant to store my Princeton Tec battery in the refrigerator this year. At least it was in an air conditioned home over the summer.

no commute. I ride at 3 am on weekdays and during the day on sundays. Batteries sit on the floor in my air conditioned home year round. I am in south Florida.

Thanks for the links. I will check them out.

are you leaving the battery plugged in? this my only real complaint the switch will draw power and drain the cells if left connected.

Well, you just answered a question I had. I'll have to start unplugging the light from the battery when I'm done.

Any idea how much power the switch draws when the battery is left plugged in?

I emailed dinotte to get that answer and how much power was used. but I was only told that there is a drain.

No, I am not. Because I am paranoid, I put the batteries on the bike right before I go to ride. Until then, that set stays plugged in. Then, the other set goes on the chargers.

sounds like everything was replaced but one light. do both lights drain the batters at the same rate? are you using both lights on one battery? it does not sound like it since they should ahve 3 hours per cell.
myself I would test run time by trying the light with a fan on it to help keep it cool and time the run time.

Yes. It was actually because of the new loaner they sent me that I was able to weed out the light engines as the source. Both drain it at the same rate.


are you using both lights on one battery? it does not sound like it since they should ahve 3 hours per cell.

No. I run each light engine on its own battery. Rear is on a 2 cell battery and each front on its own 4 cell battery. Length of time is almost exactly the same give or take a few minutes.


myself I would test run time by trying the light with a fan on it to help keep it cool and time the run time.

I did this already for each of my battery sets before I sent them back to DiNotte for replacement. Results were exactly the same. Actually, I even did it with the batteries charged with the old charger first and then the same with the new charger. Same results. I have not done it with the new batteries, but will do it this weekend.

I am not one to bash manufacturers. I tend to give a lot of room for performance, but no matter how I look at it this remains poor in my book. Actually, pretty poor. For the batteries that is.

When I sent my stuff in, I noticed they had a new 800L model. I see their advertised battery duration is about 2 hrs, but they use the same batteries that the 600L uses. I was ready to either order a dual 800L light engine or trade my 600L for it, which they offered to do for me for a fee. I wanted to wait and see what happened with the new batteries. I am glad I did because if I am getting 2/3 of the battery life with the 600L, the 800L would be either leaving me stranded in the dark daily or I would have to run them at medium intensity, defeating the purpose of going with higher lumen in the first place.

Just beware.............:notamused:

Hrmmm...so the chargers might be bad? I just received a dual 400L set and the battery charger's indicator light does not light up. No idea what it is doing or if it is doing anything.

Try a different outlet. Make sure the batteries are in tight.

Thanks...I've tried at least three different outlets...no idea how much tighter I can jam them both in.

My helmet light is a 400L and it came with (2) 2 cell batteries. My ride is about 2 1/4 hours. I would get the flashing low light indicator at about the 2 hour mark. The batteries are rated at about 2.5 hours.

It is baffling to me why they don't know what the flashing low warning time is.

I have put the 400L on a 4 cell battery, since I don't what to be bothered changing batteries in the middle of nowhere at 4:00AM. My 600L (handle bar mounted) is good because running full power with a 4 cell gets about 3 hours, which is well within my ride time.

Keep us posted. This is a very interesting thread.

the Li-I charger for dinotte should light up green when there's no battery connected or fully charged and red when it's charging.

the AA/AAA NiMH charger will light up once you plug a battery into it.

IronMac

Ok, then it's officially dead because the light never comes on. Drats...

Okay, I'll throw one more thing into the mix (Note - I still have to email Dinotte to get their take on it):

My charger light pulses from dim green to bright green when I plug a charged battery into it. I thought it was supposed to be steady green.

Anyone have this happen on their charger?

Steady RED when charging.

dgasmd,

Check out the Dinotte home page for a link to info regarding a recall notice for batteries manufactured before May 2007. I don't know if this applies to your issues, but it's good to know that Dinotte stands behind their products.
