Maybe the best choice for the caving headlamp- H50 2.0

The H50 has won the favor of members of the expedition team with its ultra-wide beam angle of 125° and high CRI light source.

In a scientific caving mission to explore the 'Jade Dragon Cave', Acebeam H50 gave full play to the advantages of its wide light-emitting angle and near-natural light source, giving the explorers a broader and safer visual perception in the dark and empty cave, and a near-natural sunlight experience.

The mission was a complete success, recorded and published in the 'Geographic of China' column.

In 2022, Acebeam launched the H50 2.0 version, which uses SST20 LED, and retains the throw TIR lens in the middle, but changed to a flood TIR lens on two sides, it can realize complementary functions of spotlight and floodlight.

A few questions?
1) are all modes fully regulated (except for turbo)?
2) Are the LEDs on their own mcpcb and can they be easily accessed?
3) Is it possible to order an extra floody optic to replace the center spot one?

Thank you

thanks for your asking:
1)Acebeam uses a constant-current circuit and boost driver design in flashlights. This means that your LED should maintain its average brightness until the battery dies out instead of slowly dimming over time.
2)the three LEDs on the same mcpcb base;
3)we do not recommend changing the standard project;

Hi Acebeam!

I have two of your lights so far, TK18 and H17. Very pleased with both of them - great products...

I was checking out the specs of this light a few days ago. The previous model H50 claimed to be "fully regulated" but ZeroAir review found PWM.

You say "Acebeam uses a constant-current circuit and boost driver design in flashlights."

That's great, but can you confirm if the new H50 2.0, specifically, is constant current?

That is to say, does it use Pulse Width Modulation or not?

Just wondering is this normal or is something failing already:

Low
Real life difference in led brightness is quite significant.. but it's only in low mode
