Emitter cell always on?

Has anyone seen this and have an explanation? The cells remains lit with the light on. But if I disconnect battery it goes off? Any way to fix it? It’s a CREE XHP70.2 emitter.

Thanks.

What’s the light?

I had similar problem with a 4*18650 Astrolux light a while back, MF02 if I remember correctly.

Edit to add: yes MF02, this is the video I made to send to Banggood. They sent a replacement head instead of a refund.

It’s a Thrunite TC20 V2. Did you sort it?

If it has a FET it could be that that’s leaking a bit of current.
Interesting it’s only one segment that’s lit.
