I have a Laguna 2000 (I think) UV filter with 16 watt bulb in it. The
bulb is dead and the protective glass around it is broken.
Could anyone point me where I can buy spare parts and a bulb?
TIA

We have a Laguna 2000 pump and I am betting that is what you are saying. We
also have a Laguna UV light that has the 16 watt bulb. If you can't get the
bulb in a store where you live, I would suggest going on the internet to get
it. Just look up Laguna products on a search and you should be able to come up
with the actual Laguna web page.
