Hello,
I am considering buying a flashlight from Convoy. Before doing my research, I was planning to purchase the 3X21A model with the LHP531 combination. However, when I asked Gemini, it mentioned that seven LHP531 LEDs could provide 2,000–3,000 lumens during long-term (stable) use. I know it will heat up very quickly in Turbo mode, but I was estimating that it could provide 5,000–6,000 lumens stably under normal conditions.
Will I only get 2,000–3,000 lumens during prolonged use? Is there an LED combination in the 3X21 series that can provide 5,000–6,000 lumens for long-term use? Or, what is the optimum combination among Convoy flashlights for maintaining the highest lumen output for the longest duration?
Would you like me to help you answer these technical questions about the Convoy 3X21 series and LED efficiency as well?

Check out the 3x21b, with 70.3 it sustains really well. Hybrid beam, very useful.
As far as I know, about 2-3K lumens is the limit for passive cooled lights. Just about every light that sustains 5K lumens or higher is actively cooled with a fan, an example being the acebeam x75.
The xhp70.3 is a little better for sustained output in the 3x21b but it’s going to be much more expensive because the xhp70.3 is an $8 LED whereas the lhp73b or lhp531 is $1.80 a pop.
