Marginally. According to djozz’s test it looks like at 6 amps, the Luxeon V has a VF that’s 0.1 volts lower. Probably not enough to make a big difference though. Lumen output looks nearly identical despite the Luxeon V being a 4000K LED. So if you’re going for a CCT change, the Luxeon V could be a good fit. You might have to modify the V’s 4040 MCPCB a little to accommodate the screw sticking up to prevent it rotating. I measured the stock MCPCB at 16.7 mm. Honestly, swapping for a different SST40 would be a much easier option.
I recently tried swapping mine with an 3V XHP50.2 just for fun. Lumens increased a little, but it also got hotter faster. I will say, I expected the tint shift to be worse than it is. On a while wall, I can see it but it’s really not too bad.
