I am looking for integral LED GU10 3.6w for a fire place. Please can you let me know if this is the right bulb?

I would need more information on what you are replacing I'm afraid. The GU10 cap is a standard size, also the spotlight itself are generally the same size. If it's a GU10 you are replacing it will be perfect. If you are unsure, please contact us either using online chat or sales@lampshoponline.com with a photo.
