Looking for an adjustable continuous light for macro shooting (ring?)

[JBW]

Brian, on Amazon (UK), I came across:
Neewer CN-160 Dimmable Ultra High Power Panel Video Light Kit, for £38.99 GBP. LED of course!
It specifies 660 lumens, and 900 lux at 1 metre.
Any help?

Of course, more grist for the mill, thanks
