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 Tongue Out

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.

yeah, mine had a big, and strange, chip/burr at one of the lanyard holes, and it was completely anodized lol

hardly touched it and it fell off.

I should have taken a picture. I couldn't figure out how they made it.  It was like a donut.  maybe they drill a pilot hole then hog it out to size real fast.

When the finish gets beat up I'm going to strip the anodizing and shot peen it.  might not even wait for that...

I've finished shimming the collar w/ copper.  Easy mod if you have the right size sheet.  I'll do some pictures at some point, the epoxy is setting...

I'm not as into throwers as most of you guys are...so I'm not sure what to make of this photo.

It looks like it really stomps the BC40 (which I'm assuming is stock) - but I have no idea what reputation the BC40 has...

It's simple a good quality and cheap flashlight ($40 from DD with coupon) with good balance of flood-throw,  overall nothing special.

A common UltraFire C8 xm-l has almost the same ability as BC40, but the quality difference is significant.  Plus you get a lot of spare o-rings + a holster with bc40.

here is a comparison C8 mouse out, bc40 over

C8 has a little better throw ability (when the battery is full)

very helpful, thanks for taking the time to post that.

I don't own a jetbeam, yet, but I imagine they're much higher quality than this thing.

nice pics Smile

Meanwhile, I measured the led current (with the modified driver) , and got only 3.2A. In this case, the driver efficiency is somewhere 72%. But something wrong with this, because I tried out the reflector with an another led which was powered directly from a lab power supply, and around 4A got the same 53000cd. That's interesting, maybe the DMM self resistance, or the PWM output ditsurbed the measurment.

 ...and I did a new modification. Now, if I turn off the light and wait about 5sec and turn on, it will start in Hi mode in any case.

How did you did such mod? Modes in this flashlight sucks, when I turn off, next time I turn on it starts in the next mode, and not the last used.

 

I have to say that, if anybody wants to make a review of this flashlight here at BLF, you can use my pics Wink

a resistor there Smile :

You can play the value of the resistor. I used a 30kohm, but if you put a higher resistance, for example 100kohm, the time will increase to about 10sec.

This is how mine behaved stock (might have been a few seconds longer than 5).

But I !@#%@#^!@#$%^  cooked my driver yesterday.  Not exactly sure how, probably too much heat from soldering gun (small iron is broken and stupidly used 140W automotive one).

Hearing that it was inefficient makes me feel just a bit better about it.

That was 5 minutes in my case.

Bad to hear that. 140W is a little strong. Smile

I think my current measurment was inaccurate so the efficiency is higher than 72%.

actually, I misremembered that from when I had a weller - it is 150/230W!

http://www.sears.com/craftsman-solder-gun-150-230-watt/p-00954046000P

great for most stuff - goes cold to hot in under a minute - not so great for circuits.

Well, additional info: Stock driver pulls 2.70Amps to the LED, in my case with two fresh charged 18700 XTAR.

Don't know why the SST-50 driver takes so long, I ordered both things at same time! Both with Tracking N°.

I wish the $20 one was the same - 55.87mm head versus 58mm, as well as fewer fins.

 

If anyone has an extra one they would like to sell or barter for, please let me know.

I'm starting to realize why you guys joke about the xxxfire lottery.  There is one small imperfection in my reflector, but otherwise, no build quality issues with mine.

I ordered the sst-50 driver on Dec. 8th.  They shipped it Jan 8th.

Anyway, it won't fit the pill, or at least it will require a serious mod.  I will do it if I can't find one that fits.  I want at least 4A but not more than 4.5.  The light will just be used for 'wow' and brief long distance searching, otherwise I would consider that a big waste of battery capacity.

I've ordered this for testing.  http://kaidomain.com/product/details.S009442

aqualab driver db says a user reported 3.3A but doesn't sound like it was heatsinked.  KD says 5A. 

So far I have resisted stripping the ano but if I like what I end up with I will strip it.  I've done some informal experimenting w/ bare and anodized aluminum and a torch.  I think ano holds in a lot of heat.  Flaw in my experiment...measuring by touch - it might not make much difference w/ air as the sink.

Truthfully though, I just don't like it much.  Give me silver, black, a color, and in shiny or matte, but this is just kind of weird...

Sorry Chicago-X, I'd been watching price on every version of this torch for awhile:)  The manafont one looks pretty good. 

If this ends up an (exceptional) performer I might buy this one. 

HAIII and 4.3A

http://www.cnqualitygoods.com/goods.php?id=1185

no group pricing but I bet he'd be happy to do some Sealed

edit: but...i guess if you're thinking multi emitter mod, you'd want the cheapest option...

dthrckt, Ric said he only has 1 last piece for the On The Road X6.  That piece is flawless. 

I have the OTR X5, it definitely does not feel like it's a budget light.  More of Solarforce M8 / Dereelight.

Thanks for the heads up. 

That's unfortunate, since I've already spent about $300 in the last 3 weeks (on this stuff alone).  I know...just average for you:) 

I've been watching that page for quite awhile, hoping I'd snipe one (...it!) if the price dropped a little.

I did notice that last night - so tempted, but yeah, the price is really ~72 because I'd swap the emitter right off.  I guess I could ebay the sst-50.

the driver is as wide and tall as the pill

dx sku  13619 (59mm mentioned above) and 13569, 66mm

much more dome and much less edge on 66mm

it also has a shorter focal length than the other, and does make a good image of emitter, albeit w/ a substantial corona. 

the focal length is so close to d1 emitter distance when placed on directly on reflector that I would have to rig some kind of holder (so as not to use reflector) to determine the exact best distance.

But, it is unfortunately significantly too wide.  You would have to remove more of the dome than viffer did here http://budgetlightforum.com/node/6030#comment-98081

I get 2x the lux w/ just the reflector than w/ both (visually and on meter), and although the beam would look better, I can't see how not using the reflector would increase reading (w/ only lens).

But, I will eventually find a host for this lens - it should be very impressive.

avoid the 59mm sku 13619, this is my second sample and both make multiple scattered emitter images at focal length.  maybe Ok for just tightening a beam, but not full throw.

some notes:

don't force, tighten the pill too strong, because you could break the ceramic pad of the led, beside that, if you haven't lucky you could short circuit the driver 

here is mine

you see the lower part of the emitter, nevertheless I don't want to replace, it works perfecly

I made a bigger hole for the led

Yeah, same characteristic as hs-802, but not so aggressive.

HS-802 reflector  with xr-e isn't so good with unusable tight spot, but with xm-l much better. I like its beam profile, a very strong spill with a strong spot. Here are some comparison pics with difference shutter speed:

left: hs-802 +xm-l

I've also modded my HS802 with XML (tried it with R5 too, but result is not worth mentioning - bad). But than again, with XML it throws similar liek Keygos - much smaller, compact light. 

But you lose throw with XM-L. The 802 deserves a XR-E R2 @1.5A to 2A IMO

Received manafont driver (linked above) from Chicago X today - thanks!.  Excellent packaging and quick shipping, hooray!

The base can be trimmed to fit the pill.  The vertical board can be very minimally trimmed to an interference fit. 

The coil (transformer?) is an obstacle.  The pill must be bored ~1/8" and still the coil has to be pushed down and toward the center.  I'm taking a break from that to keep from getting hasty.

Height might be an issue.  It is so close that I can't say for sure until I'm done boring.

I'll probably have to plastidip the board/coil to ensure it doesn't short to the pill.

Driver fits.  The height is ok by about the thickness of a penny.

measured current to emitter - 4.3A, 1.8A, 0.4A

OUTSTANDING

Done for the day, I don't want to push my luck.

http://www.manafont.com/product_info.php/flashlight-component-triple-t6-...

note: if you shave the contact board slightly more on the side opposite the coil, you'll have to bore just a little less...

Anyway - 4 < 4.3?  not according to match's tests. 

http://budgetlightforum.com/node/2603

Also, his readings were taken 10seconds after power on, and brightness during those ten seconds is my primary goal. 

This will be a fair weather search light in my boat and will rarely run even 10 seconds at a time.  You're not supposed to use 'headlights'...they obscure the lights that indicate your boat's heading to other boats.  I just do short bursts to make sure there isn't some obstacle in my path (floating log) and to search for a spot on a distant shore.

BUT, since I'm undoubtedly not heat sinked as well it might be true in practice w/ the D1, especially beyond 10 seconds.

In any case, I prefer to err slightly higher than lower.  I'm not concerned about emitter longevity, I always have a backup and...I'm sure I'll be swapping the emitter to U2, and then whatever is available next Smile

SST-50 Driver from DX will never fit, it's way too big and can't be modded. It just doesn't fit! Sad

Please dthrckt post a pic of the pill with the new driver if you can.
