CX2829 is the controller and the MEM2309 is the FET. Though really the 2309 FET only has one input, plus 3legs is for Vcc and four legs is for Vout - theoretically only need three pins so why they put in in 8-legs I never know.
CX2829 is somewhat kick-ass cheap controller being able to provide output 1.5A by itself in that tiny package. But it’s only used to control the 2309 FET here, and this FET in my experience can only give out around max 3A when driving older XMLs.
But we’re probably jumping the gun here - not sure which driver we’ll get anyway - this one will be Ultrafire version (instead of Skyeye).
Cutter sells triple and quad boards that fit 35mm TIR optics. The Ledil Cute-3 and Cute-4 as well as the low profile GT4-xp series. The only 2 boards I’ve ever seen anywhere else fit these fantastic optics where Pilotptk’s integrated board and one made in EU, also integrated.
Yes, all dealers close for the week-ends. Nothing will happen till sometime in their Monday afternoon. So, some time Sunday in the wee hours, or best look sometime Monday. Most likely with a bunch of orders, it will be Tuesday till they start to move out.
I was going to order two, plus a couple of other items. Total was just over $30, and was going to add tracking but decided I might as well use that $2 towards another light and get free tracking. Like getting the third one for $8.
Now, knock off this group buy madness for a few months. Please!
I just got an email today with a (China Post, I think) tracking number (I paid the $1.99 for the number). The number is still not working, but will post back when it does. I’ll wait until the number starts working, then I need to “remind” them that they need to refund PP for a light (not an F13) that I had included in the same order, but which they said was out-of-stock).
For the record, it took about 6 days for the order to get to this point, but 2 of those days were weekend, so net, about 4 days for them to ship and/or get a tracking number to me.
