DEAL ENDED - DX XM-LT6 900-Lumen 5-Mode White LED Flashlight - Titanium Color (2x18650) - $29.99 (Normally $41.30)

here's a teaser for you

imho, this light is very well designed - except the lack of a side switch...

Yep...looks like it, you need to compare with others to compare how much though.

I will buy a better one...it just keeps getting bumped down the list by lights, drivers, emitters, etc lol

Can you post a pic of the bottom of the driver. Is it a cheap driver?

driver - as you can see it is soldered to a brass collar in the pill, otherwise I'd pop it out so you could see the other side...

I took it at an angle so that you could see the little gap between the pill and collar

here it is again w/ the collar removed. the little hole at 9 o'clock must be to aid in removing the driver

and one more to show how the pill sits in the collar. I'm holding the pill slightly higher than where it actually sits or you wouldn't see the gap.

if you put a 1" copper coupling around the pill there is a gap, and there is also a gap between the coupling and the collar. I forget which gap is larger - one was 0.012 and the other 0.022. It should be very easy to use copper sheet to fill both gaps.

There's really no need to do it though. After thoroughly greasing all the threads and doing a 20 minute tailstand run on high the whole light is nearly the same temperature - very warm - (by feel...didn't bother w/ temp probe). Even the tailcap...

Finally arrived. Hmmm, very budget feeling, a lot of failure (dents) outside on the anodized layer, very dusty lens and reflector, no memory function(??wft), little off center emitter.

Measured 1.38A at the tailcap, but it depends on the multimeter and the leads, with thinner leads I got 1.6A.

Overall brightness is about 8% less than BC40.

42000cd that is not so bad, but the quality...

after a little modification on the driver, now the tailcap current jumped from 1.38A to 1.9A, with thin leads from 1.6A to 2.2A. The led current is somewhere 3.8A.

I got a solid 50000cd. I tried with higher current (2.2A with thick leads), and got above 53kcd, but the brightness sag was so strong, and I didn't want to overstress the driver and the led, so I reverted to the lower 1.9A.

Now, I am satisfied with the result.

I just put an additional 0.56ohm resistor there:

I tried it without the poor glass lens, and reached 55000cd. Something wrong with this lens.

edit:

Okay, I found a lens with almost the same diameter, which is far better than the original, and finally, the best value was 53000cd @1m (measured from 3.17m). That is enough for me.

SWEET. love you man lol

I have to find my bag of resistors, I might have one of those.

edit: although, I will probably stress the LED a little more because if it burns out I have an excuse to buy better tint

ugh, came home for lunch, it seems I only have resistors in the 4 - 6 kohm range

this is where my knowledge is seriously lacking - ie where to get or scavenge stuff like this...

So in output, this is no Trustfire X8, huh?

First, I am not an expert. :)

As I see, the most important part of the circuit the power mosfet, which drives the led. This is a "40n03" mosfet, and its rated current is 4A continuous and 16A pulsed. The other power component is a 4.7uH coil,

and conclude from its size, its rated current above 5A. So if you don't want too much from the driver, it can be modify.

no, you have to put a lower resistor somewhere 0.3-0.4ohm range (if your driver is the same as mine).

HA! maybe you're not, but that sure sounds like some 'expertise' to me

where do you get your resistors? I just browsed radioshack's site in the hope I could snag one locally but didn't see any near that range.

first mouse over/out pic

distance 200m

mouse out UF D1

mouse over Jetbeam BC40

I ordered from here: http://net-market.hu/elektroart/, but this isn't so helpfull because this is a hungarian site. :)

Try to find a webshop. Better if you order resistors with difference values, for example 0.1, 0.22, 0.33, 0.56 0.82ohm etc., you can fine tune the driver with these.

thanks, I'll find a US one, to hopefully save on shipping. A big kit would be great, so I don't mess around ordering $1 parts every time I need one...

your beamshots show why I can't use this light around my house (tight suburban homes). Inside 30 yards (backyard), novices would think the xeno e03 is brighter. But shine it down the street 4 houses away and people inside turn their lights on to see wtf is going on

Do you have any other lights in this class to compare it too? I don't...so I'm just curious what your opinion is. I'm not too into this kind of light...but they're cool enough that if there is a better (budget) one, I'll get it eventually.

Today arrived mine, feels cheap, seems to throw well (tested with daylight, comparing with my throwers)

LED is too blueish/purple, but I don't care in this case, for me color is OK.

I haven't measured anything yet because I'm waiting for the SST-50 driver to arrive, ad then I'll see if mod, or change the driver, depending of the current at the LED.

huh, I wouldn't describe mine as feeling cheap...definitely feels budget though.

But, the more I look at the textured shiny gray anodizing, the more I think it looks cheap.

but hey...it WAS cheap

I just tested it at night and... I like it, and very much.

Even standard-stock, it is awesome and better if you consider the price.

I said it was cheap because of some small imperfections before the anodizing, and also at the tail I had to remove some aluminium... But it is OK anyway, not the best, not the worst.
