GX53 fittings can be surface mounted (slim profile, easily hid by cupboard pelmet or invisible if the cupboard is low enough, recessed (hole in cupboard base) or standalone metal fitting (typically IP rated wall light but usable anywhere).
Always check if the GX53 bulb comes with the fitting - they are about =A35+delivery otherwise which adds up, some fittings say the do not come with them (and yet do!) whereas others rely on someone assuming they do. For a look at fittings do a search on Ebay for GX53 with & without the search "include description" ticked.
Always check bulb life, it can be a lot shorter than you think.
Alternatively if the light is too poor close to the cooker, have you considered a cooker hood with a light? Simple stainless Elica Krea was about =A389-99 on Ebay, John Lewis. Easy fit, you need a 127mm core drill because recirculation sucks and extracting cooking moisture is a very good idea.
