Good to see that DX finally got the accessories that Geoman has had for a while now.

The cable accessories are no good for me though, because of the cheapness of the connectors I'm going to wind up cutting them off and soldering on new connectors anyway, and then I'll be able to roll any cable I want.

Besides DX and Geomangear sites, is there other site that you can order the MS from?
I have seen posts for other sellers, but I can not find it now.
Thanks,

There are some eBay sellers. I think I read that they charge more than the other places. Not sure why anyone needs a choice besides Geoman. He ships immediately, free shipping, uses USPS priority which gets anywhere in the US in like 2 days, and his prices are close to as good as you can find, and many, many stories here show that he has as good customer service as anyone.

I ride DiNottes. Love them. But I know a guy who rides MagicShine, and I can always see him from a goodly distance. Lumens/dollar, it's resetting the market. Durability and warrantee coverage is the only question, not saying MS isn't durable, I don't know. But I can say, if you want light up your pathway, and let drivers know you are there, and you don't want to spend $400+ for a bright light, MS is REAALLY GOOOD.

The MS is not as durable as the LiIon Dinottes, certainly. But the durability is not worth 5x as much. As I've said a few times, I wish MS would have another model with heavier wire, a solid mount, really good connectors and a sealed battery box. They could sell it for $150, have more profit and I think people would jump on it.

The existing one is probably fine for people who don't ride in wet conditions, which really is a decent amount of the market, but there are plenty of us who would pay the extra for the extra durability.

However, the Magicshine is more like a standard bike light, has 4x the energy stored in it's battery pack (it's 4x as big) so it can go longer, and is a bit brighter (like 10-20% brighter) at least for me.

If you're talking about "resetting the market", give credit where credit is due -- they're both doing it.

the p7 flashlights are the same brightness, but as you've mentioned, lack the runtime. i don't think a light with ~45min of runtime can be considered a serious bike light.

In my experience (I do own both), the DX P7 flashlights are slightly less bright -- probably due to a lower voltage (4.2v max vs. 8.4v max into the control circuit.)

But they make great bike lights. They seem to last about an hour in maximum brightness mode, and it's trivial to carry around a few batteries as spares (at $4.09 each, why not?) In the lower brightness modes, they'll last about 4.5 (medium) and 9 (low) hours and even the lowest mode is still brighter than most < $70 bike lights.

Personally, I leave mine in medium mode most of the time and go to high as needed. But then again, most of my riding is in the city where there's other light sources and I rarely need the full brightness -- but it's nice to have it there when I do.

I have a Magicshine as well, and use it in the same way -- though with only one battery pack, it's a little harder to have a spare, so I can't just ignore the battery's condition like I can with the flashlight. (I guess I could make a spare battery pack -- that's easy enough to do -- but I haven't done it yet.)

Added advantage of the flashlight version: put a $1.55 mount on each bike, and just move the light from bike to bike as needed.

The single 18650 cells are probably not going to be quite as bright, because I don't think any of them have regulation circuitry. I've looked at output curves for 18650 cells, and it looks to me like the flashlights will only have maximum output for MAYBE 10 minutes. By the time they get near their 45 minute limit, they are probably only going to be putting out HALF the light, if that.

The MS starts with 2x the voltage and current necessary, and has a regulator so the current to the LED will be constant until it shuts off.

If you're arguing that the $90 Magicshine is a better bike light than the $50 ($33 light, $4 battery, $1.50 mount, $6 or $12 charger) DX P7 flashlight, sure.

However, they last over an hour on full, not 45 minutes, and while the brightness does decrease near the end, it's not really noticeable until you get close to the end. I do believe there is a regulator of some sort in there, at least in the model I have (I've got a third one that has no flash modes and it seems to use a resistor to reduce the brightness rather than PWM for the low light mode. Nasty!)

I have two of them, so I may have to do some tests -- fully charge both, compare the brightness (they're approximately equal, I've already done that) then run one on full (with a fan to cool -- they do get warm with no airflow) for 30 minutes and then turn on the other long enough to compare brightness then turn off, 10 minutes more, compare brightness, 10 minutes more, compare, etc. repeat until the first one dies. I'll report here when I've completed this.

Larger Magicshine Battery Back in stock?

looks like all the sales over at all-battery.com are over and done with;

both the 7.4VDC/8.8aH and the 7.4VDC 5.2aH li-ion batteries are all sold out;

and have gone back up to the normal day-to-day pricing(which is still decent btw).
-------------
Fortunately, I managed to pick up two more of the 7.4VDC/8.8aH li-ion batteries.

Now mind you the regular 7.4VDC/8.8aH li-ion battery at $72 is still a great buy;

cost competitive with two li-ion 7.4VDC/4.4aH batteries at $38.00 apiece or $76.00 for two.

The nice thing is one has the option of doubling the amp hour capacity to 8.8aH;

for about the same price, which should yield much less overall wear and tear

on the li-ion battery and extend its life significantly as an added bonus and dividend.
--------------------
Looks like 2009 has been a good year indeed for Magicshine having taken the;

bicycle LED high intenisty lighting system market by storm.
-----------------------
Just got the li-ion battery order in from all-battery and the magicshine DC power connector jacks

from geomangear, so I can finally solder on the the DC power connector jacks onto the ends of the li-ion batteries.

Now I will have not only one of the brightest cost effective high intensity LED lighting systems on the market;

but also one of the longest lived li-ion battery running times to go along with that as well; which is just as important.
----------------------------
This is because during cold weather the chemical reactions going on inside the li-ion batteries slows down

quite significantly. thus the total overall li-ion battery amp-hour reserve capacity is reduced commensurately.

Fortunately, this will no longer affect me any longer since I will have a newfound seriously augmented and

amplified six hour li-ion battery amp-hour reserve capability.
----------------------------------
I will also be putting the li-ion battery pack in a protective insulating medium provided by the combination

of a neoprene sock and also a thick 70% merino wool sock combination together.

This combination is designed to thermally protect and allow the lithium ion battery to stay as warm as possible even

in sub 32 degree freezing weather for as long as possible to allow even more efficient li-ion electro chemistry

reactions and thus subsequently allow the most efficient energy production in very cold temperatures.
Please correct me but it looks like they are back in stock at $31.99, plus cost of connector.

If the flashlight has modes (high low etc) it has some form of "regulation". Probably in the form of simple pulse width modulation.

Warning: I bought one of those back when they had it with the "right" connector for the Magicshine - I'm finding that the connector is only "sort of" right. It works OK but the light cuts out when you hit a bad enough bump.

I found that taping the two connectors (male and female) together after insertion made it stop, because they couldn't wiggle one inside the other. But still, it's a bit of a pain to wrap a bit of tape around the connector every morning.

Right, which doesn't change the fact that the light fades over time. On high the regulation is "on all the time" and it'll fade. If the "low" mode does current sensing and boosts the duty cycle as the current delivered to the LED fades, then it might help, but I doubt it does. I bet the thing just delivers a fixed duty cycle on low mode, and in that case it would still fade.

Anyone haivng issues with the extender cable (or any cables in general)? The cable split where the it meets the bottom of the connector. It hasn't completely torn apart but no longer works.

I guess I need to get a replacement from Geoman.

You mean besides this one?

Tenergy had one that was bigger, but I bought one and the connector isn't exactly right, and it's more expensive than that now that it's off sale. If I needed a new battery I'd just get one of the ones linked above.

Have you removed the plastic wrap from the old battery, dried it thoroughly, let it sit and dry overnight, then tried recharging? It'll probably still work fine. I have had very good luck with drying out electronics and having them still work.

Here's another -- https://www.dealextreme.com/details.dx/sku.32756

Downside of using this link vs. IJM's -- it will arrive in about a month rather than a week. Possibly more difficult to get support if needed.
Upside of this source -- it's $30 instead of $42 (with shipping).

More like two months. The last item I ordered form DX was listed as 'In Stock' and took 59 days to reach me. The order before that took about the same, plus Chinese New Year is coming up which will delay things even further.

It's not even remotely worth it to save $12.

I've made 21 orders from DX of various things. Two have arrived in two weeks, three or so in three weeks, the vast majority in approximately a month, perhaps three in five weeks and one took about two months (that one actually went to Poland first according to the HK PO's tracking page!)

As for the $12 -- that saves you almost 30%. It may not even be "remotely worth it" to you, but it might be to somebody else. It also comes with the cover where GM's doesn't. (Which you probably don't care about if you've already got a cover.)

(Though really, if somebody is able to do some soldering and re-use parts of their old pack, they could just buy two two packs of the 18650 of batteries for about $16 total, saving a whole lot of money. Though to be fair, soldering batteries does require some skill -- if you're not fast enough, you'll ruin them.)

DX used to be a lot faster, but in the last six months or so they've really gone downhill with their shipping times and stock availability.

I when it comes down to it I'm, willing to pay an extra $12 to be able to ride at night within the week, not within months.
