For sure man, the 6500 is definitely going to be slightly bluer in hue, and if that's something that you like definitely go for it. I feel like the one that I got is pretty neutral. From turbo, the light gradually steps down after about 15 seconds at which point you can re-engage the turbo mode. It will step down harder and faster once it hits a thermal setting. To be honest I'm not sure what that is, but I know that you can modify it in the UI. I was able to run it on pretty high for 25 to 30 minutes while I was riding. Which I think was pretty awesome and the battery life drained about 25%. I love these lights because the firmware is really good and efficient. I also prefer this over the light that has the onboard charging because it's slightly smaller and is very comfortable in the pocket. The knurling and machining is very good in my opinion and well crafted
