What are my rights regarding repairs?

What are my rights as a landlord if my tenant provides false information about repairs? For several months my tenant has asked that I call out an electrician as she has had several light bulbs blow in the house. I explained to her that this is normal and suggested better quality bulbs. This did not satisfy the tenant, so I then consulted my electrician. He gave me a report with the common causes of blown bulbs and again recommended better bulbs if she was not satisfied, he also advised that blown light bulbs did not by themselves indicate that anything needed repairing. After passing this information along to the tenant I was then informed that one of the kitchen lights had stopped working and I had 10 days to get it fixed or we would be off to the tribunal. My electrician went out to the house and charged me for two hours labour plus travel to replace five light bulbs. He could find no fault. Is there anything I can do?
