Do you live in the US? It looks like daylight PDT is not approved in the US for use with Metvix. I'm not sure why they stopped it. But it is available in Canada, Mexico, the UK, Australia, New Zealand, 7 other European countries, and probably other locations. Hopefully the FDA will approve it soon because it's efficacy has been proven to be the same as blue/red light photodynamic therapy and much less painful. If I ever need to get it done in the near future I will definitely be going to Canada or overseas.
