    Ordered this lamp for our UV water treatment system, price was good and delivered safely next day.
    The lamp ELC supplied was the industry code for this bulb (GX018T5L-S400) but was perfect. Michael responded quickly and thoroughly when this was queried. Would be helpful to others to detail that in the description.
    It’s now fitted and working well.

      Many thanks for the positive feedback. I’m glad we were able to help you get your uv system up and running again. I have amended the product description as suggested which will help others to cross reference this lamp.
