Review: NANJG 105A 2800mA driver

Haven't found one either. Well, with all the XM-L lights flooding the market let's hope that more different drivers will follow.

Thanks for the replies, brted & sixty545!

[note to myself: find out how to quote multiple persons in one post]

sixty545 if you can be bothered to do current draw for hi med lo at tailcap that would be sweet.

Spendid review. 4.70$ of mine are on their way to HK.

I first considered this as it works fine with my MC-E:

I will be happy to measure the current draw, but am not able to do it yet. Thanks to our dear government I could not buy a drop-in with XM-L which costs way over our import limit, so I had to make two orders of one XM-L star each at DX. That happened dec.23 and I have heard nothing from them since. I have a Skyray P60 host and reflector with pill ready to assemble my first XM-L light.

The percentage numbers in my review are from oscilloscope measurements of pulse width's.

I think it will be safe (but expensive) to use 2 x CR123A 3V primaries if you only look at voltages. But there will be generated lots of heat. The two extra Volts dropped in the regulator at 2.8 Amp will generate 2 x 2.8 = 5.6 Watt on top of the 10-11 Watt with a single Li-Ion cell. That must be a no-go.

Thanks for a great review. I especially like being able to eliminate the irritating strobe and SOS modes.

Yeasterday I got this http://www.kaidomain.com/ProductDetails.aspx?ProductID=11130 XM-L from KD

I put it in a P60 with this driver http://www.kaidomain.com/ProductDetails.aspx?ProductID=1845

I put 4 volts direct to the led and measured 3.4 amps on my lab power supply.

With 4 volts through the driver I measured 2.7 amps. Installed in the light I measured 2.4 amps

Very happy with the lightoutput - amazing. The led was ordered from KD the 23rd and arrived on the 8th.

KD has improved a lot lately!

At how much is your import limited to? Mine is 22€ which is 29,xx USD atm acording to google.

I think the free of duty limit is set by the EU. The UK version is £18 which is roughly the same amount. But our Post Office doesn't seem to care much about stuff from China. Up until now, I have never had any order queried or opened. And I doubt Customs here are all that bothered.

Looks like a good driver. Was that measured at the LED or tailcap?

He is from Denmark and he has troubles getting a dropin which is roughly 17usd... that picked my interest.

Since the values on the packages are all incorrect, what our customs know, they check them from time to time. Sure they are unable to estimate the real value either way. But when they open one and they feel like asking for a proof, they usually charge 11 euros for the procedure, regardless if the receipt shows, it was less than 22 euros or not. When I order goods from a store, where I have to pay the shippment I don't split the orders. Usually, three out of four of them go through anyway without to get checked. So finally, when I count all together I still win.

The limit is 10€ (incl postage!). Over this: 25% wat and 22 € handlingfee to postalservice for collecting this for the customs.

The limit where you have to pay 25% VAT is 80 Danish Crowns and has NOT been changed in 15 years!. That limit is equal to about $13.80 but the PO add another $28 fee to do you the favour. That way an order of $14 becomes $45 . In the Christmas razzia I got confiscated 3 lights costing around $16 each. I will not throw good money after bad ones so I just cry a little and wait for another opportunity to re-order. The PO returns the goods to HK I think.

We only have to pay toll on orders bigger than about $198 and normally this is only 6%.

Ouch! That is low. The USA the last time I looked allowed $100.

The UK limit is also including postage, but I thought all of the EU now had the same Customs regulations.

I measured it by connecting the possive to the +spring up through the light

and the negative to the threads at the tailcapend of the tube.

I have now tried to put the + to the +spring as last time, but now put the negative

to the spring in the tailcap and this to the threads on the tube. Now I measure 2.2 amps.

A small loss in the switch apparently.

Træls!

Here it functions this way: If the EU regulations are to the benefit of the population or customers,

its the national rules that apply. If EU rules benefits the State the national rules dont apply!!

Go-daw do!
