Modded Weltool T1Pro V3 – FFL351A 3700K

Decided to fix the T1Pro V3’s cold, greenish tint by swapping in an FFL351A HI 3700K. The result? Really impressive. It keeps alot of that awesome throw but gives me a much more usable hotspot, and of course, a much nicer tint and High-CRI. I also beefed up the internals by switching Weltool’s thin MCPCB for a 16mm Convoy board. Had to use a thinner gasket to compensate for the extra height so everything would close up properly.

Since the 3700K runs a bit hotter than the stock SFT-25R, the extra copper should really help with the thermals.

Excuse the scuffed emitter edges, my cheap tweezers definitely left their mark 😉. It's from an older swap, but the emitter works just fine.

Did a quick runtime test, but I had to cut it short at the 10-minute mark when it hit nearly 70°C🔥. In the real world, though, that’s not an issue, I rarely blast it on high for long stretches. Medium mode is my go-to, and it’s more than enough for daily carry.

Output is 670 lumens on high/turbo, with medium coming in at 250 lumens, and is sustainable without the light getting hot at all.

I can already tell this will be in my rotation much more often. Between the slim profile, the crisp, tactile tail-switch, and a UI that just works for me, it was already a great light, now it’s even better.

Overall, it’s basically a tactical 14500 take on the SC65c or FC11C, but with a more compact form factor and that tactical tail-switch.
