I dunno for sure, but thinking ~4.6A, maybe less to the LED. The MT-G2 runs at a higher voltage than a XM-L2, so the voltage output of the 2 cells in series is delivered to the LED, unlike a buck driver for an XM-L2. How this buck driver regulates the MT-G2? No idea... I'm sure there are loss's from the cells to the LED - always is with buck drivers.
Thing with these lights is the batteries and charger cost more than the lights. Ordered one with tubes, thanks for the discount the. I think going to let my in-law buy the batteries. I know giving a gift that doesn’t work is strange, but I can’t get myself to buy new batteries!
Might change my mind though… I’m already 6 batteries behind
Thanks to the for setting this up. I did miss the other GB from GB.
Ordered one plus two tubes. My brother-in-law has been wanting a good cheap thrower to wow his Boy Scout troop on night hikes to spot animals, so he got in on the deal also.
Did I read a thread here about some potential slow shipping with GearBest? I never ordered from them before.
Shipping from GB has been decent for me. Not as fast as FT or IOS, but not like some people experienced. I’m not sure if it was just people outside the USA, but some people had big shipping delays.
I ordered one with 2 tubes. Has anyone tried 4 or 5 * C batteries? I am thinking about it. I have two other 3 * 26650 lights that run off C batteries. Not as well as 26650 but good enough in an emergency
It’s sold in up to 3s configurations. I’d assume that 12.6v is the highest sanctioned input voltage. I haven’t made a list of QX9920 based drivers, but this is what I came up with just now:
HX-1175b - spec’ed a few different ways, but the highest input voltage spec I’ve seen is 15v. Other listings say 8.4v.
Solarforce XM-L2 dropin driver at Solarforce-Sales - Spec’ed at up to 9v. My (brief) earlier look into this indicated that they skipped the (semi) “regulated” PSU section for the QX9920, so this driver is probably limited by that more than anything else.
Patrol King - no spec, but it’s physically setup for 2s, so take that FWIW.
