Lovely little light unit. I did not read the size specs prior to buying and was surprised at how small they are, but, it works out well as they are for my hallways so the closer the ceiling the better. The only downside is that they fix to a joist with no option for a metal mounting bracket. All good if you have a joist to fix to otherwise it could be an issue trying to mount directly onto just plasterboard. In a nutshell these are lovely looking small lights and check, no bulbs, it is stated in the description and standard GU10 Led bulb fittings so no problem with that at all.
