IMHO a parallel LED arrangement would be the logical choice. A parallel arrangement would more closely match Vin from a single cell, 3S = 9-10Vf, 3P = 3.2Vf. So a less complex driver circuit could be used in a 3P setup. Also, 18650 cells (and their protection circuits) can easily exceed 3.5A too (FWIW).
How hard the emitters are driven is anyones guess. My experience is 18650 cells get unstable at currents greater than ~5.5-6A for 3-4 minutes. Mine get SCORCHING hot under such conditions, and I generally get an uneasy feeling when they near the ~1.5C mark. So hopefully the lights designers kept this in mind.
I have had this light in my cart for a month… not going to pull the trigger just yet though. I just can’t get past that hideous gold color YUK!! I’d snag one in a heartbeat if it were gray or black
*Just for info, a lot of sites rates sites like for example dealextreme, dinodirect, shenzhen-wholesale and many other sites such as these as untrustworthy. But they are not from the experiences here in BLF. Definitely there would be issues/mix-ups experienced before, but they are not scammers.
Powerwholesale net is the same coy as bestinone, i think the main one is sz-eyoung. If you search this site it is where lots of us get our generic IMR cells. Same ones as shao.fu.tzer is selling in CPF marketplace.
Lots of people here have done biz with bestinone before. 1 of my packets took 29 days though, but that’s with the problem with CPAM.*
Anyway, ergotelis ( Greece) and eudardo (USA I think) just got their 2 units of Trustfire X100 2 weeks ago and reported on the 3300 lumens OTF findings, both within 3 working days. Purchased from this site via DHL.
BTW I made a mistake and I’d like to clarify that shenzhen-wholesale and szwholesale are 100% not related, and szwholesale is the source for the XTAR cells and not shenzhen-wholesale which is another business entity. I have edited the above.
Thanks !! Appreciate the good wishes…
You never know what you’ll end up with a untested re-seller.
I paid with PayPal , so I’m at least partially safe.
Before I forget ……
Mine arrived in New York this am.
If all goes well , should be in hand Monday / Tuesday . (sooner I hope)
The ad states that the light uses 2x18650/26650 batteries yet the picture and the advertised length of 177mm suggests only 1 battery. Am I missing something? I am willing to take a chance on a light like this but I am a little confused.
Don’t know. I just thought it sounded kind of short for two 18650 batteries. I was going by my 7g5 with the extension for the 4th cr123 is quite a bit longer than that. I guess the crelant has a much deeper head though. Wouldn’t the clicky tailcap take up another 20mm or so leaving only 20-25 mm for the head? Just trying to visualize this. I like it and want it but just want to make sure.
I never trust specs on any Chinees sites.Think they are just copied/pasted from something in a rush. DinoDirect is one of the worst examples of this.Headline says “Single” and picture looks like one battery.Hope for an extension?
I’ve ordered a lot of things so far this year. With the exception of a
tail cap for my G2 from DX , everything has arrived in short time.
Apparently, this will not be one of them…
