Thanks for fixing the link, E1320. I received the first pouch today with the batteries and the charger. Unfortunately the charger has the wrong plug. So do they automatically pack a US plug and not the required country plug @ DX? Or shall I claim the wrong plug? The other thing is that the batteries didn't arrive welded in plastic foil, but in a damaged and scratched plastic case. I wonder if I have received used batteries or if DX usually ships the batteries in a plastic case? Shall I claim this to get brand new batteries or (if I did receive brand new ones) to get a acceptable plastic case?

They should have included the correct plug by the location on your order. Definitely notify DX ASAP so they can send you the right plug. The batteries should have been shrink wrapped in plastic, I am sure they were damaged during shipping some of the packages I have received from them have been very beat up.

I am already visualizing the duct tape over your mouth.

I finally received the delivery of the flashlight and the bike mount after returning from holiday today. And I have to say that I'm again disappointed with it: The flashlight has deep scratches on the head and the tail cap although packed well in bubble foil. And the bike mount is not working as it should. The flashlight isn't hold tightly even screwed absolutely tightly. And the plastic grip of the screw (for using by hand without a screw driver) that should fix the flashlight drops away when screwed tightly because it contacts the tube. I have just prepared the dropin with aluminium foil and will test the flashlight tonight. Hopefully I won't be disappointed with the light itself. Should I order this bicycle mount http://www.dealextreme.com/p/universal-adjustable-bicycle-mount-for-flas... in order to attach the flashlight securely on the handle bars?

Did you use the included rubber inserts to make sure the flashlight fits tightly, see the inserts in this picture.

Ofcourse I did use the rubber inserts, but the flashlight could still easily be moved back and forth.
I hope that the mount with the velcro strip will hold the flashlight stronger.

 

I tested the flashlight last night and I have to say that I'm also a little disappointed with it.
The light is really bright and the illumination in the close range is really good. But I asumed that the beam would be farther.

I think this is construction related issue of the P60 drop-ins, right?

In order to get a farther beam I probably need a flashlight with a bigger refelector. However the reflector may not be to big as the flashlight shall be wearable inside a trouser pocket.

 

So is there any recommendation?
I found the Keygos EK5 XM-LT6 which seams to have a farther beam and a refelctor seize I could live with. What do you think?

I have never heard (or seen) DX to change to correct plug. However, most of eBay sellers do this regularly.

In DX, there are some chargers available with different plug, but they are always listed with different SKU. If the charger you want can't be found with correct plug, you need to order also a converter. For example this converter can be used for US->EU.

Your drop-in was underdriven for longer runtimes, right? That might affect the throw significantly.

What I have read, that Keygos has a tight hotspot, possibly making it not suitable for a bike light. Of course you could use both! Your current light for flood and add Keygos for throw..

DX has already sent me the cable with EU plug.

I don't know if the drop-in is underdriven. How can I check this?

So, if the Keygos has a tight sport it doesn't come into consideration.
I should check if my drop-in is underdriven and may look for a directdriven one.

If you have a DMM, you can check the tailcap current. See instructions on HKJ's page: http://www.lygte-info.dk/info/Measurement%20UK.html

Anything over 2.5A is good, less than 2A is what I would call "underdriven".

A well-known good drop-in can be found here: http://www.manafont.com/product_info.php/ultrafire-cree-t6-3mode-memory-led-dropin-module-42v-max-p-5178

I got one of those and it draws about 3.4A from a XTAR2600.

Yup, OP reflector and 1.4A current afects the throw. Just get full current drop-in with SMO reflector and then interchange parts so you'll find the best combination for you.

As a mount I would suggest this - plain, simple and good grip for 18650 based lights. We are using it on several bikes. For biger dia hadle bars use some tight strip insted of screw.

Thanks for your explanation and the link.

I will check and come back with the current.

What is the difference between OP and SMO reflector?
How can you remove the felector from the dropin? Just pull it down?

Is there any other 1x 18650 flashlight with a bigger refelctor than the P60s that makes a better throw than a directdriven WF504B?

 

I can't imagine that the flashlight should hold tightly on this mount at it doesn't get fixed on it at all.
I prefer the mount with the veclro stip because it can be removed fast and span the flashlight completely.

You can just unscrew reflector from drop-in. Find all about drop-in at http://flashlight-wiki.com/P60 and http://flashlight-wiki.com/DIY_P60.

There are a lot of bigger reflector ones like C8 style. They have thighter hotspot but you still have to chose which reflector suits you best SMO or OP - same game as with P60. I like it SMO more because it gives more even beam and you see more surroundings. But you have to try it by yourself - depends also on speed. The higher speed - more throw is needed ie. tighter hotspot.

Belive me, rubber mount is better and holds flashlight very tight. I use it on downhill through woods on very bumpy trails. You need a lot of power to pull flashlight off. Welcro mount might be slipy (depends on flashlight body surface) and can be better for smaler lighter flashlights.

Is there any flashlight with a bigger reflector than P60 that makes more throw and the same flood and however at the same time is not too big to still wear it in a cargo pant pocket?
This flashlight should be at same price level as the W504B is.

I think I will try both of the mounts a see which one is the better for me.

I tried to check the voltage of the dropin today with a noname DMM at 20mA. The DMM showed me values between 7 and 9A. That can't be possible. Is it just because of the bad quality of the DMM? Or could I have done something wrong?

You need a DMM with a 10A plug so you can measure up to 10 amps. Setting your DMM at 20ma will not give you a valid reading. So you need a better DMM to answer your question.

I am already visualizing the duct tape over your mouth.

Okay, thanks for your reply, E1320.

So I will check with a friend's DMM that has a 10A mode.


By the way, can the dropin be damaged while checking.
Especially at the beginning when the contact to the battery tube was not so good, the light flickered a bit.

It is pretty unlikely you shorted out the drop in testing the amperage draw with a DMM the flickering was probably damage being done to the DMM not the drop in.

Could that be the reason for the inexact data?

I think the flickering was only beacuse I pushed the -pin on the thread and there was no proper contact.
Later it worked and the light was permanently on.

 

I only wanted to know if this flickering is not good for the dropin.

So I finally measurd that amps draw of the dropin today and I am surprised that it is 4,66 A in high mode! And course the flickering was only because of the different mode that changed when the contact of one pin was interrupted. So the dropin is not underdriven at all and the flashlight should make the bst light possible for this configuration. The flashlight is very bright, not a question. But the beam should be thrown around 50 metres further. In order to get a further beam I need a flashlight ith a bigger reflector, right? What 18650 flashlight do you recomend that still fits into a pocket of a cargo short?

I have been using a pill from UF XM-L dropin in this host. Throws like an animal, but gives you some usable flood as well.

You already have a well performing dropin, so you can just buy the host and replace the pill. Easy mod, no soldering, grinding or whatsoever. Just separate the pill from dropin, screw in the pill to the new host and you are done.

That might be the best alternative, if it fits your pocket. Should fit?

Thanks for the recommendation.

Is this also a clone of the Ultrafire U80 as the Keygos EK5 XM-LT6?
If so the Keygos should be the better bang for buck light.

Are there any other U80 mutation that could come into consideration?

TF-R2 is actually a Dereelight DBS clone. It's a bit larger than Keygos, which is unbelievably small (just received mine), and has bigger hotspot. Keygos has small, very focused hotspot.

TF-R2 feels better in hand and seems to be higher quality. Keygos feels like a toy to me Smile

Is there another thrower that has also an acceptable flood? Is the flood much worse compared to the WF504B? I don't like this hotsport of the TF-R2. Does this stand out outside, in normal condition, also? The WF504B has a more even beam and not such a hotsport what is an advantage. Is there a thrower like the TF-R2 with a more ven beam like the WF504B?

Throwers tend to have a tight hotspot. That's what makes them throw so well..

If you want throw without tight hotspot, you need lumens. Many many lumens. For example any of the 3xXM-L will throw quite well AND make some kind of "wall of light" as flood.

A flashlight's reflector with 3 XM-L is probably to big for carrying in a cargo pant pocket. And it will be too expensive, too. Are there any action pics of the TF-R2?

The C2 XML-T6 has no issues with the hotspot. The SSC P7 of the Magicshine MJ-816 has a visible donuthole in the hotspot, the hotspot of the C2 has no donuthole, it is brighter, and the hotspot is a little bit wider.

IS there the C2 body avaiable seperately or only the comnplete flashlight? The KD C8 from Kaidomain seems to be a clone of the C2. What is better TF-R2 or C2? Are there any alternatives to these two flashlights?
