Ebay has light meters from £10 up to £££. Varied ranges, accuracy and
features.

The meter is required to evaluate optimal downlighter options (kitchen
worktop etc).

Any recommendation(s) please?

A secondhand one from your local photographic dealers. They can be had
for next to nothing now that cameras are all largely automatic.

The main limitation with photographic meters is that they are intended
to measure reflected light, and for this application one wants to
measure incident light - i.e. taking the illuminated surface
reflectivity out of the equation.

A simple Lux meter like: http://r.ebay.com/DCs70G will do this quite well.
