Apart from any consideration on the seller (which I don't know)
my bigger question is from a technical point of view: 5 XM-L claiming over 5000lm??
That means a lot of juice from the batteries!
I don't believe it's possible to achieve those numbers from only two 18650 in series.
The rule of thumb of one 18650 for one XM-L applies I think...
If those 5 leds are in series, it would need roughly 3,5v x 5 = 17.5v at an Amperage of no less than 4A to achieve 1000lm each. 17.5v x 4A = 70Watts from TWO 18650 batteries??? No way!!! even with boost drivers there's no way, a theoretical (unreal) 100%efficient driver would need more than 8A from the 2 in series 18650 batteries, recipe for explosion, maybe?
With a good boost driver, and pumping 4A from the batteries (which could be safe if high quality with pcb) each XM-l should see somewhere around 1.8A that means a max overall output about 3000lm.
Hi Rockspider, you are very correct to say that. :) Check out the other Trustfire TR-J12 threads, we have made measurements and you would know what to expect.
I would like to offer my apologies to Mr. Karlnapf.
I had to track my posts down since the watched post engine was reloaded but I didn't forget to make sure I made things right about my accusation, to either prove it or not. Well it is certain that I was wrong about you Jorg and I do apologize. I do hope everyone understands my reason I was so sure you were a spammer from reading my posts above. Mr. Admin has deleted the know spammer sanseven who was the first to respond to this thread. All other posts that sanseven was involved in was tag team spam, please understand I wasn't judging you Jorg on your grammar or spelling!
I'm glad you stuck around Jorg! This is a great place and we all, like myself, seem to guard it from scum bag sellers posting spam links and we have took alot of spam from blulans.
I didn't mean to hijack this thread but I just wanted to make public my embarrassment for accusing you and offer my formal apology. I was wrong and I am sorry...I do hope you forgive me and may the flashlight gods be with you and bring you many padded envelopes!!
The light should be the same really but i like Manafont better due to faster shipping so to me its worth paying more, but each person will have a diffrent opinion i quess.
I am waiting now for more then one month. I am on "backorder" . Has anybody else this bad experience with Deal Extrem? I never ever will buy anything again. Happy that everybody knows that I am not a spammer.
Hey Rockspider.. 70W from 2x 18650 (and even double of that - 140W) is quite possible if those 18650's are A123's LiFePO4 ones ;) That's what I am using with my FF STL-V2 mod and they work like beast (+ they are completely safe, which is main advantage of me as I wouldn't risk running more than 2 Li-Ions in series)
