Rated 5 out of 5 by walt49 hard to find, expensive if you do
1000bulb has these in stock, locally the electrical wholesale house could not find them in their catalogs
1000 bulbs worked personally with me to up grade my pond installation to increase my wattage application( upgrade ballast) into my existing ultraviolet pond filter to use these lamps which are less costly then the existing 8 watt lamps saving me money and allowing my application to be much more efficient, cleaner water no algae.
I buy six at a time ,use two every summer into fall

Rated 4 out of 5 by alpinehap UV light helps clear up water.
I purchased this UV light to help with algae control in our outdoor pond. It definitely helps in clearing up the water.
I will be ordering more of these.
