I noticed today that the “blf” code does not work for items that are on special.

I just added 3 of the olive ones to my cart and applied the bulk discount and BLF coupon. The result was a total cost of $11.82 for all 3 posted, which works out as $3.94 each

Yeah I just ordered 3 olives for the same price as you and also 2 of the c8 3 mode which is on sale for $10. I want to order silver ones.

Olive is silver…. They have it mis labeled I think. Though it does have a very slight greenish tint… I mean slight…

If the Olive is closer to silver I’ll probably buy one myself soon as that’s my preferred color. I bought a Blue one months ago and I’m very pleased with it. Great value for such a good quality small torch. On 10440 it runs very nicely. I think this is one of the best deals around for anyone wanting a AAA/10440 size torch at a low price.

Good to hear the ones I ordered are the silver ones. Looking forward to these lights. Where can I get decent 10440 batteries?

I received a pair of Ultrafire 10440’s years ago (5+) as a free gift on a purchase on Dealsextreme if i remember correctly and only used them recently for the KD Buckle and found they were still working after all those years.

I found a similar set on Fasttech

https://www.fasttech.com/products/1420/10000930/1078100-ultrafire-10440-...

These should be ok, there are probably better around. Mine provide 25 minutes of runtime.

Those have been fine for me too, but I can’t say I use them a lot. I’ve had them for years without any issues though.

The EFEST 10440's are far better - mtnelectronics.com EFEST. RMM shows the HKJ's comparisons, comparator here: http://lygte-info.dk/review/batteries2012/CommonSmallcomparator.php. The UltraFire's in capacity, stay with the EFEST up til 0.5A, but higher, the UltraFire's fade away.... I still have a bunch of UltraFire's, but really prefer the EFEST's. There's not much choice out there though.

That doesn’t surprise me at all. I would get the efests without a second thought if I needed some new ones. Good link and info.

That's always a problem with these very low capacity cells. The best charger is one with a 200-250 mA charge rate. The UltraFire's, even though they say 600 mAh are actually about 350 mAh, so normally you want to charge at or below 1/2 the capacity (0.5C), though some say up to 1C.

I use the OPUS BT-3100 for these now, but the XTAR MC0 looks like a nice quality, cheap charger for this: mtnelectronics MC0 for $5.90. Also the "VP" series of XTAR's Richard sells will work fine. Richard is listing these chargers the right way - he won't say a charger supports 10440's unless it supports a low enough level. Others advertise chargers supporting 10440's just because they can physycally fit -- big difference...

Thanks Tom E, I already ordered the MC0 from gearbest as they have a sale going on. Will order the efest batteries from mtnelectronics.

If you have a charger that can charge LiFePO4, I have been using the Soshine LiFePO4 AAA’s in my buckle with a good increase in brightness over Alkaline. Not as much as a 10440, but runs cooler too… Just an idea.

i asked CS and got very fast response:

Quote:
Hi Martin,

Thanks for your inquiry.

For XHP50 5500k (S024311), it is J4 3C.

For XHP50 6500k (S024311), it is J4 1C.

Our XHP70 is N4 6000K to 6500K. According to the Cree specification, N4 is better than N2.

Or do you have any preference?

If you have any question, please feel free to contact me. Thanks

@ our Pros:
how good are the hxp50s?

Could you tell what the point of a u4 bin is? Surely that’s a step back from the xml2.

> what the point of a u4 bin is?

That wouldn’t be the main target of the production run.

Binning takes the output of the run and sorts them by color and efficiency.

The odd bins collect the emitters that came out a bit off the target; they get sold cheap by discounters to people willing to buy small lots or single items.

Quote:
During production, LEDs will vary in colour, flux and forward voltage and this is also true for products from the same batch. The differences are significant and therefore LEDs are measured and delivered to the market in subclasses or groups called bins and this process of segregating LEDs is called binning. So a particular bin may contain LEDs, which emit light within a range of wavelength, range of flux values and also the range of forward voltage that can be applied safely to the LEDs….
… In the case of a high quality LED luminaire product, proper binning will ensure all the LEDs used have no visible differences in flux (brightness) or colour. However, in case of a failure it has to be ensured that the new or replacement LED has to come from the same bin as the LED which has failed.

But the u4 bin is not as bright as an xml2 u2?

I’m seeing 869 lumens for the XPL U4 VS 1119 lumens for the XML2 U2.

I don’t see the point in the XPL at this bin.

Please tell me if I am missing something as I have no experience with the XPL.
