With regards your enquiry about the SP-50L7HX. I can advise that the bulb has an expected life of 30,000 hours and is covered by the 12-month warranty. As this unit is so new there is not an exact price for a replacement bulb but we expect it to be in the region of £50. I hope this has been of some assistance to you. If you do have any further queries, please do not hesitate to contact us.

Maybe someone else could mail them too and see if they get a different answer.
