FW3T

Just want to know what people’s opinions are of the FW3T in stonewashed titanium are

as to what , exactly?
I think it performs almost the same as an aluminum, but the heat transfer is poorer. Poorer still than the copper version…

Do you mean people’s opinions on how it looks?? Because that should only matter to you…if you like it, buy it

anyone in NE ILLinois into get togethers?

Does that mean that it gets hotter faster

Yes..I believe it will throttle back faster

It’s the other way around. Titanium conducts heat less well compared to Aluminium, therefore you’re not going to notice temperature increase quickly. However, heat will build up inside the light, and the led temperature will rise much faster.

Edit: inside the light it gets hotter faster as heat builds up. And outside the light where you hold it with your hands it does not get hotter faster.

So to be clear, the Ti will not pull heat from the LED as well as copper or aluminum.
So it will throttle back on output a bit faster than those two. Looks stunning though..

Then again , these lights can pull off quite a show, albeit for a short time…Then they have regular old boring output..

How much heavier is the Ti-Cu version compared to the all-Ti version?

I don’t think this conclusion can be drawn. The light should throttle back faster, but this depends on the design.

1) Thermal sensor is placed on led board. The light will throttle down faster, because the led board will get hotter quicker as heat is dissipated slower. I know Thrunite does this, and I believe this is not the case with the FW3T.

2) Thermal sensor is placed on the driver. I think this is the case with the FW3T. This means that the heat from the led board has to travel via the Titanium shelf (single piece with the head) to the driver. This means there is a higher thermal barrier compared to an Aluminium light. So the ledboard increases in temperature faster, but the Titanium shelf slows down this“information” to the driver where the thermal sensor is placed. I suspect testing is required to get accurate numbers, and my guess is that the Titanium light needs a different thermal program compared to the Aluminium variant.

Anyhow, this is just my take on it.

Ti is 74.5g , and I assume the Ti-Cu could be ~ 90g

Nice guess. I measured mine to be 87g.
