I think the Haikelite MT03’s hotspot diameter might be a little too big for your usage. Not talking about the absolute throw distance but rather it hitting the ground/water, esp since you are gonna be kayaking.
Maybe get both the Convoy L6 and the BLF Q8? Actually if you don’t mind hearing me out, may I suggest the BLF Q8 and Sofirn Q8?
The soda can form factor really makes practical usage sense, cutting the flashlight length dramatically but still maintaining hand-holdable diameter. I have over 50 flashlights, very big to very small, very long to very short, and those in between.
In fact these soda cans are still pocketable in case you are gonna take it out from the Kayak mount, just a bit on the heavy side so when you walk you’d feel the mass moving around. Also they use 18650s, so the batts are interchangeable. The Convoy L6 uses 26650s. The L6 and Sofirn Q8 would come in handy should you need 200+ metres illumination, which could be rare in your case but not impossible i guess?
When the lights are that good, you’d not only mount it on the kayak mostly……as you progress farther along the path of a flashaholic other than just for hunting and kayaking use. And in those cases, you’d want to pocket the light in one way or another (jacket, jeans, vest, coat etc).
Trust me, most of us have been there done that. I have been in the hobby for like 17 years now, though i took a short break and “came back” recently.
The Sofirn Q8 is a 100k cd cool white version of the BLF Q8. Hotspot area of the Sofirn Q8 is going to be around half of the BLF Q8. Both are very good price, the Sofirn can probably be had for just a few dollars over usd 39.95.
If you think having 2 different variants of Q8s is crazy, then the L6 would do also.
