Just added a LH351D in 2700k and 5700k to my collection. (Note: the LH351D were on 10, XM-L2 8x7135 on 35, and 219C/SST-20 4x7135 on 100%)
Left to Right - Cree XM-L2 6500k, Cree XM-L2 4500k, Cree XM-L2 3000k, Samsung LH351D 5700k, Samsung LH351D 2700k, Nichia 219C 5700k, Luminus SST-20 2700k.
This is a big step. Kudos for Simon for implementing it. With the 10 times tap I keep entering the config mode unintentionally which is very frustrating. With this driver that won’t happen anymore.
@Simon, when will the 5A 12 group driver receive this update?
AA/14500 driver can use 12 groups program, but the cost will increase greatly. Because T2 did not sell much before, I did not consider producing this driver.
There seems to be some margin for error with the new drivers (like there was with the old drivers…)
I have 3 of the new 17mm 5A 12 group drivers. One of them acts strange. When programming the light the LED remains on but dim in between programming blinks, and seems to have a much higher lowest mode than the other two.
The other two drivers work as expected, the LED is off between programming blinks and the lowest mode is pretty low.
I ordered a few more to mess around with. I’ve used two of them to make S2+ triples.
Simon Mao, on my flashlight from the last order (convoy s2 + LH351D 5 Amperes), a shunt in the spring from the side of the button fell off, and this happened almost immediately, literally after 2-3 battery replacements. I don’t know how to do soldering and I don’t have a soldering iron!
The question is: what are the consequences?
It is possible that because the internal resistance becomes larger, the low-voltage protection will be entered in advance. I have a switch with a copper spring, which can be sent to you for replacement.
Well, that’s a shame. I have some button top 1000mah Vapcells I was hoping to use with the T2 I just ordered. Might need to look into what is preventing the fit.
On another note, I’m looking forward to my M21C-U XHP70.2 and another simple S2+ with a Dogfart and the new FET driver from the same order.
I wish we had figures for the new XHP35 HI offering in the M21C though, I would have maybe bought another if there were candela ratings available.
