Florescent lighting has characteristics that affect color rendition. This color shift is not usually visual to the human eye but will cause adverse effects on film.
When shooting under "daylight" florescents your pictures will have a purplish tone. Hoya's FL-D filter corrects and restores a normal color balance.
In industrial situations you might encounter "warm white" florescents which will give a greenish tone, requiring Hoya's FL-W corrective filter.
Both filters are available in coated and multi coated (stronger flare prevention) versions and all popular sizes.
One reason why the Hoya 67 FL-W is popular is because of its Clear optics

Good value product.
I just received the filter a couple days ago and have only used it once and the results are fine, It will give me another tool for the bag that I can use when needed
This filter really makes the sunrise sky and the setting sun sky look impressive. This filter makes the most dramatic skies of any of my filters. The colors are great.
Another nice filter to the collection
