Bulb for Rangemaster cooker hood

Hi

I’m struggling to source a bulb for a rangemaster cooker hood.. it’s only been fitted for 2 weeks and bulb flickering already, but bought (new) via eBay months ago, so no warranty. The bulb looks smaller than the usual MR16 types. Picture below. Any thoughts on what I can get / from where?
The hood is model LEIHDC110SC

Cheers

James
