Good question. For that led it definietly need some more cooling fins. Maybe a design like MF02.
But I think they will do the cheap way. Slap in the led and it will heat up superfast and stap down.

This LED won’t be any worse than the XPH50.2 edition?

I’d love to see this light with a flat white.

It depends what you mean by worse. It’ll heat up faster than the XHP50.2 but also have a lot more throw.

Without additional cooling, you’ll get 3 seconds on turbo before your hand combusts Wink

I’m sure it’ll last at least a minute on turbo. More cooling fins dont help turbo runtime much. Thermal mass does. If the smaller and lighter NI40 can handle this LED I’m sure the FT03 will be fine. Only thing is it might take long to cool down once it’s heated up.

Nah, I will have full 4 seconds thanks to the help of oven mitts. My hands could do even longer but solder melts so fast…

But jokes aside – IIRC my Emisar D4 pulls 18A and I don’t complain about it overheating too fast. This one will be fine.

On a separate topic, I’m fantasizing about having this light with Andruil. Is the charging board on the same PCB as the driver or is it separate?

I don’t think it will heat up that fast, the head is quite large. The handle is long, and hoping for a better beam profile than the NI40, similar to the current ft03 with XHP50.2

Aaah…before I forget, this sbt 90.2 beast only consume high drain battery rate 20amp rather than mid drain battery. You tell me, where are the high drain battery you’ll get from?? Its in “21700” category only, e.g 40T, p42a, vtc6,.

So, my point is that…why would we build a “26650” host FT03 where I think 26650 is still in the mid drain category? Even 21700, single of it gonna drain like crazy? I thought is that, we need a specialize high drain battery host just about enough amp for the sbt 90.2 to function properly.

So,
● single 21700 high drain cell, enough power(or not) but short of capacity(it will short live boring)

● single 26650, short of amp but longer capacity(less lumen than advertised)

Option(probably) ● triple(or quad?) cell host design not sure specific 21700 or 18650, ofcourse in parallel connection. With this, gonna give the sbt90.2 suitable amp draw.

So what do guy think? Take a look deep at the Lux perpetua project and I must been thinking, he has probably more true about sbt 90.2. Here link

In search of the most ideal flashlight in town:
1. BRIGHTNESS
2. Durabillity
3. Design
4. Quality
5. Price$$$
