In my experience, (making note that I know not what I say) when the meter shows that “-” in front of the amperage number the current is being read in the wrong direction. Changing the position of the wires fixes that and almost always shows a different number, usually lower.

I'll re-measure when I get home from work tonight, with leads reversed to see if the DMM gives a different reading. I don't think it does, at least on this meter, so I don't worry about the lead orientation.

On that note, when testing amps at the emitter, has anyone noted different readings taken from each side? Is there a preferred side to take the reading from?

I'd assume not, being the one circuit, but someone might know otherwise.

Ok - Just took measurements of the same setup back to back to back, & using my meter, there is no appreciable difference with the leads reversed.

I really wish I had not read this thread. I really never intended to mod anything again.

Ordered one of these from GB tonight

• Have to make a new Copper shelf for the led.

• Modify the Reflector - take out the center flat area in the bottom and make a custom thin centering ring. Stipple the reflector. Not going for max throw obviously.

• XHP70 led and custom mcpcb.

• Time to go look at what I got for drivers for the XHP70, or email RMM.

• Rework the spring plate 2S/2P. Actually, the batts will probably load from the tail end now, like the modified SRKs I’ve done.

• Make a different handle maybe.

I hate you guys. (Not really, but the wife will hate me ).

Well, I can’t speak for anyone else. But for me, it’s good to see you back in the game. I’ve missed reading your awesome build threads! :bigsmile:

+1 - it really is an inexpensive platform for something of this size. Looking forward to O-L's results - sounds like a plan .

NO STOCK AT GEARBEST. As usual, they are selling stuff that there is no stock on and as usual, I canceled the order. Thank's Gearbest, you are my best line of defense when impulse buying, because you never have anything in stock.

Gearbest dropping the ball again, sigh. :|

I interpret GB's 3-5 biz days as this:

"we ain't got it, but we thinks we can get it quick"

So technically true - anything 3-5 biz days is not in stock with GB. The "we thinks" part can drive you nuts at times though .

BOSS1 gb is up for discussion today. Apologize to all for the delay, vendor overlooked one of my 4th Jan reply. I proposed for custom upgrade parts but it was turned down due to low demand (<100). Anyway, we will try our best to group buy back on track and list the stock light up for sale soon.

MAY’s answer was “we may get it next week, if it comes”. Not good enough for me, “3-5 days” here means it shipped and will take 3-5 days to arrive.

Sorry to disorganize the GB. It looked like it was on hold and not moving forward, so I posted about GB.

Back to the original thread.....

[bugsy36]

Hey Justin - No worries. Soon the wife will join BLF to find out what you need to mod and then order a bunch of stuff for ya....just to get you out of the house. LOL

[Tom_E]

Yikes, with May saying 'if it comes', I'd be in doubt for sure. Glad to see the GB is getting a bump. Thanks freeme, again!!

I confirm that, just recieved a mail, they ask me could i wait just a little….10-15 working days, maybe a little bit more….

What can i say, i was so exited about that flashlight….

Oh well, stock is acceptable. Time to start setting aside cash for batteries for this ridiculous beast. :P

[DB_Custom (Dale)]

Have batteries, will wait.

Nice to see you contemplating again Justin, warming up a bit huh? Beautiful day today, just gorgeous out… 65 and a light breeze, blue skies, but I’m sure we’ll get some nasty yet, always seem to in late Jan or early Feb.

[Mitko]

65 and a light breeze

I think its time for you to accept the SI system, that 65 is kinda scary to me
Celsius, meters, good things like that

He was speaking in Celsius.

it gets hot in Texas

[Mitko]

OMFG! Realy? I cant believe that! Once i had 54 in Egypt back in 1999 and i never ever want to “feel” it again

65……and Tamafly costs 130$….Texas isnt a place for me realy :bigsmile: realy 65? Come on, its unholy temperature

Tom… here we go…

Edit: Sorry, forgot to mention, each LED was tested for 20 seconds.

It was difficult taking photos with my mobile phone of all the readings I took. I eventually only took 2 photos of my setup.

Here I’m measuring a fully charged 25R. I’ve used the 25R to get an indication of the voltage drop when applied to an XP-G2 S4 LED. With initial contact, it dropped to 3.99-4.00 volts.

I then had to dialed in my power supply (seen in the background) to 4.70 volts to get 3.99-4.00 volts when applied to the LED. The wires running from my power supply is thin and quite long.

The wires running from the amp meter to the LED is 18 gauge and around 10cm long. The amp readings I get on this meter is 99% in line with that of my Fluke Clamp Meter.

Here’s what I got. From low to high readings:

IOS XP-G2 S4 2B, domes on

4.6 Amps | 3.97 Volts (18.262 Watts)
4.6 Amps | 3.98 Volts (18.308 Watts)
4.7 Amps | 3.95 Volts (18.565 Watts)
4.7 Amps | 3.96 Volts (18.565 Watts)
4.8 Amps | 3.94 Volts (18.912 Watts)
4.8 Amps | 3.94 Volts (18.912 Watts)
4.8 Amps | 3.95 Volts (18.960 Watts)
4.8 Amps | 3.95 Volts (18.960 Watts)
4.9 Amps | 3.93 Volts (19.257 Watts)

I then reflowed my only 5 x FastTech XP-G2 S2 2Bs onto 16mm noctigons, domes on

4.6 Amps | 3.97 Volts (18.262 Watts)
5.3 Amps | 3.85 Volts (20.405 Watts)
5.3 Amps | 3.86 Volts (20.458 Watts)
5.4 Amps | 3.85 Volts (20.790 Watts)
5.7 Amps | 3.78 Volts (21.546 Watts)

For the fun of it, I them measured 5 x XM-L2 U4 1C I had available, dedomed

4.7 Amps | 3.95 Volts (18.565 Watts)
4.7 Amps | 3.95 Volts (18.565 Watts)
4.8 Amps | 3.93 Volts (18.864 Watts)
4.8 Amps | 3.94 Volts (18.912 Watts)
4.8 Amps | 3.94 Volts (18.912 Watts)

I think they got you pretty good, I think they were kidding about celcius and Farenheit.

That's right, it only gets that hot down here ;)
