Convoy H4

Headlamp I recommend is Convoy H4 519a 4000K constant current driver. It’s right angle so you can use it handheld also. It is ultimate bargain under $30. I have 2 of them, one 3000K & one 4000K.

the Convoy H4 is so much better. I thought the spot plus flood mode would be nice to have but the brightness drops off too much. So I really only like the hi cri flood & the H4 519a beats the pants off of it.

I would go with H4 Nichia 519a 2700K for high cri or 1800K for warmer low cri. It comes with perfect 45 degree bead optic.

I have a convoy H4 with the B35AM 5700k and it's super nice. The 21700 battery does make it a bit heavy, perhaps, but I found the included convoy strap sufficient to keep it quite steady.

get an H4 with the B35AM in 4000k (maybe H2 - use those 18650's? B35AM isn't a very thirsty emitter).

I have the H4 in the same setup. Absolutely love it and use it all the time.

I got a Convoy H4 on a whim when it first came out, with a B35AM in 4500K. It has become one of my most used work lights, and I don't even use it as a headlamp (although it weighs 10 grams less than the 18650-based HS21 when both are weighed with batteries in them!).

In fact, by adding Convoy H4 to the Alpine backpack shown in the image, you can use a total of three flashlights at the same time.
