Review: So Far So Good - This is a great value as a two pack. I must admit I was skeptical as I have purchased replacement bulbs in the past and had to send them back multiple times as the bulbs I received were defective. Much to my surprise both bulbs worked. Unfortunately, the head on my canister filter short-circuited and burned out one of the brand new bulbs. I ordered another set and, once again, both bulbs worked. I highly recommend this set.
Review: It lasts thru all 4 seasons in N.Y. - This is great for your outside ponds to prevent algea growth. I keep it on all yr, all 4 seasons & have to replace twice a yr.
