Did you choose the Thrunite T1 because the 18350 battery gives longer runtime compared to the 16430? 

Why was your S1 problematic? 

So far the only problem I encountered with all of my Olights is with my S1A.
Once you drop it (waist height), it creates a dent on the button top of the protected 14500.
Then can't use the battery unless remove the PCB and button top altogether. 
Dent is like something like below pic.

Damn... 
Got send back to dealer to claim warranty? 

olights have serial numbers and afaik, if it came from gadgetworld2u, they will honour the warranty even without the receipt so long as the light came from their stock (they keep records). excellent customer service, i must say. had an issue with one of my lights and they replaced the defective unit, no questions asked 

+9999 
I've been buying from Dannie, unker Foong and Gwen since their old shop upstairs till now downstairs and got torchlight warranty honoured before. 

whoa... i spot a tn 40 in the mix 

yeah, guess we've all been there... higher lumens, furthest throw etc etc etc. but end of day, for practical considerations, for me it boils down to price/hours of use 

query: do you guys take the battery out if not used for a long time (say 3 months or so?). i guess the modern lights have zero discharge on standby, but just curious...

p.s. mr-2, do note that olight's BATTERY warranty is only for 1 year so that's something to consider.

Nice little lights you have there.
They seem to complement one another.

For your E14, is it cool white or neutral white?
I joined the BLF groupbuy for these 2 lights combo and for the E14, I opted for the 4000K neutral white tint.
As this will be my first Samsung LED, I'm not sure what to expect of their tint, as my neutral white tints light are mainly Nichias 219B, 219C, XPL-HI and SST-40 emitters.

I just received a Jetbeam RRT03 with Nichia 219C 4000K and hopefully I can compare the tint of the Samsung and Nichia when the BLF combo arrived.
