9090 LED's (6x) in dive light - what are they?

See this Scubaboard thread for more information on these lights - ‘Cheap Chinese Video Light’

A chap reviews the differences between the A11, A15, A10

I have the A15 and find it very good. From the other posts in the thread though I am wary about the clicky switches failing after more than a few dives.

As I posted in that thread, has anyone had any experience with the new type popping up now? COB Led versions

Only ~£30 i’m tempted to pick one up.
4 x 18650 as per the others, looks to be the same chassis just with a different led.

‘uranusFire’

‘Brett’

The LED is a COB type - can’t find any information as to which one.

Im curious to see if this is more powerful / has a different beam profile to the 15 x XML-2 variants

EDIT: I have started a new topic on these COB lights here
