Convoy L6 alternative

Hi,

I like the form factor, and the price range, of the Convoy L6, just not its down-step in output ( Review: Convoy L6 XHP-70 (2x 26650/18650) ) . Thus, I’m looking for something with similar form factor, and price (I’m willing to go up) of the Convoy L6, but with a constant current of 3000+ lms for at least one hour. Is it possible?

Note: Convoy L2 does NOT have a flat run time. In Zeroair review, it was cooled to achieve the curve Convoy L2 Flashlight Review – ZeroAir Reviews
