I think they are one and the same as this 40W emitter, and I remembered they even listed 60w with the same number of die and footprint (also with less lm/w, which confirms my suspicion).
As Djozz have tested, these “40w” parts could easily be run at 60w (as long as you can cool it), and might even survive a brief period (minutes) of 100w without degradation.
I see…but why have different model numbers? Pure marketing “We have a model tailored to your needs”?
That’s very possible but maybe it would be good to ask for clarification?
I did tried that exact same convoy driver at some point on C8.2, though the stock host doesn’t give good enough contact and I can’t go into turbo as a result.
I did later try to bypass the terminals with solder braid. With Liitokala 5000mAH, it worked when fully charged, but will drop out of turbo on 50-75% SoC. After a while, I recklessly try to go into turbo repeatedly and probably eventually killed the driver with the transient after 100th attempt or so. To sum it up, if I want to use that driver again, I will probably need a higher drain battery or better bypass mod. Handling 10+ amps from a single cell is no joke here.
Alternatively, there’s a GB attempt by nzoomed. It’s a driver that could potentially drive the emitter at 50W out of single cell.
